avpak - bupropion hydrochloride (unii: zg7e5poy8o) (bupropion - unii:01zg3tpx31) - bupropion hydrochloride 75 mg - bupropion hydrochloride tablets are indicated for the treatment of major depressive disorder (mdd), as defined by the diagnostic and statistical manual (dsm). the efficacy of bupropion hydrochloride tablets in the treatment of a major depressive episode was established in two 4-week controlled inpatient trials and one 6-week controlled outpatient trial of adult subjects with mdd [see clinical studies ( 14)]. - bupropion hydrochloride tablets are contraindicated in patients with a seizure disorder. - bupropion hydrochloride tablets are contraindicated in patients with a current or prior diagnosis of bulimia or anorexia nervosa as a higher incidence of seizures was observed in such patients treated with bupropion hydrochloride tablets [see warnings and precautions ( 5.3)]. - bupropion hydrochloride tablets are contraindicated in patients undergoing abrupt discontinuation of alcohol, benzodiazepines, barbiturates, and antiepileptic drugs [see warnings and precautions ( 5.3) , drug interactions ( 7.3)].  - the use of maois (intended to treat psychiatric disorders) concomitantly with bupropion hydrochloride tablets or within 14 days of discontinuing treatment with bupropion hydrochloride tablets are contraindicated. there is an increased risk of hypertensive reactions when bupropion hydrochloride tablets are used concomitantly with maois. the use of bupropion hydrochloride tablets within 14 days of discontinuing treatment with an maoi is also contraindicated. starting bupropion hydrochloride tablets in a patient treated with reversible maois such as linezolid or intravenous methylene blue is contraindicated [see dosage and administration ( 2.4, 2.5), warnings and precautions ( 5.4), drug interactions ( 7.6)] . - bupropion hydrochloride tablets are contraindicated in patients with known hypersensitivity to bupropion or other ingredients of bupropion hydrochloride tablets. anaphylactoid/anaphylactic reactions and stevens-johnson syndrome have been reported [see warnings and precautions ( 5.8)].  pregnancy category c risk summary data from epidemiological studies of pregnant women exposed to bupropion in the first trimester indicate no increased risk of congenital malformations overall. all pregnancies, regardless of drug exposure, have a background rate of 2% to 4% for major malformations, and 15% to 20% for pregnancy loss. no clear evidence of teratogenic activity was found in reproductive developmental studies conducted in rats and rabbits; however, in rabbits, slightly increased incidences of fetal malformations and skeletal variations were observed at doses approximately equal to the maximum recommended human dose (mrhd) and greater and decreased fetal weights were seen at doses twice the mrhd and greater. bupropion hydrochloride tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. clinical considerations consider the risks of untreated depression when discontinuing or changing treatment with antidepressant medications during pregnancy and postpartum. human data data from the international bupropion pregnancy registry (675 first-trimester exposures) and a retrospective cohort study using the united healthcare database (1,213 first trimester exposures) did not show an increased risk for malformations overall. no increased risk for cardiovascular malformations overall has been observed after bupropion exposure during the first trimester. the prospectively observed rate of cardiovascular malformations in pregnancies with exposure to bupropion in the first trimester from the international pregnancy registry was 1.3% (9 cardiovascular malformations/675 first-trimester maternal bupropion exposures), which is similar to the background rate of cardiovascular malformations (approximately 1%). data from the united healthcare database and a case-control study (6,853 infants with cardiovascular malformations and 5,763 with non-cardiovascular malformations) from the national birth defects prevention study (nbdps) did not show an increased risk for cardiovascular malformations overall after bupropion exposure during the first trimester. study findings on bupropion exposure during the first trimester and risk for left ventricular outflow tract obstruction (lvoto) are inconsistent and do not allow conclusions regarding a possible association. the united healthcare database lacked sufficient power to evaluate this association; the nbdps found increased risk for lvoto (n = 10; adjusted or = 2.6; 95% ci: 1.2, 5.7), and the slone epidemiology case control study did not find increased risk for lvoto. study findings on bupropion exposure during the first trimester and risk for ventricular septal defect (vsd) are inconsistent and do not allow conclusions regarding a possible association. the slone epidemiology study found an increased risk for vsd following first trimester maternal bupropion exposure (n = 17; adjusted or = 2.5; 95% ci: 1.3, 5.0) but did not find increased risk for any other cardiovascular malformations studied (including lvoto as above). the nbdps and united healthcare database study did not find an association between first trimester maternal bupropion exposure and vsd. for the findings of lvoto and vsd, the studies were limited by the small number of exposed cases, inconsistent findings among studies, and the potential for chance findings from multiple comparisons in case control studies. animal data in studies conducted in rats and rabbits, bupropion was administered orally during the period of organogenesis at doses of up to 450 and 150 mg per kg per day, respectively (approximately 11 and 7 times the mrhd, respectively, on a mg per m 2 basis). no clear evidence of teratogenic activity was found in either species; however, in rabbits, slightly increased incidences of fetal malformations and skeletal variations were observed at the lowest dose tested (25 mg per kg per day, approximately equal to the mrhd on a mg per m 2 basis) and greater. decreased fetal weights were observed at 50 mg per kg and greater. when rats were administered bupropion at oral doses of up to 300 mg per kg per day (approximately 7 times the mrhd on a mg per m 2 basis) prior to mating and throughout pregnancy and lactation, there were no apparent adverse effects on offspring development. bupropion and its metabolites are present in human milk. in a lactation study of 10 women, levels of orally dosed bupropion and its active metabolites were measured in expressed milk. the average daily infant exposure (assuming 150 ml per kg daily consumption) to bupropion and its active metabolites was 2% of the maternal weight-adjusted dose. exercise caution when bupropion hydrochloride tablets are administered to a nursing woman. safety and effectiveness in the pediatric population have not been established [see boxed warning, warnings and precautions ( 5.1)] . of the approximately 6,000 subjects who participated in clinical trials with bupropion sustained-release tablets (depression and smoking cessation trials), 275 were aged ≥65 years and 47 were aged ≥75 years. in addition, several hundred subjects aged ≥65 years participated in clinical trials using the immediate-release formulation of bupropion (depression trials). no overall differences in safety or effectiveness were observed between these subjects and younger subjects. reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. bupropion is extensively metabolized in the liver to active metabolites, which are further metabolized and excreted by the kidneys. the risk of adverse reactions may be greater in patients with impaired renal function. because elderly patients are more likely to have decreased renal function, it may be necessary to consider this factor in dose selection; it may be useful to monitor renal function [see dosage and administration ( 2.3), use in specific populations (8.6),  clinical pharmacology ( 12.3)] . consider a reduced dose and/or dosing frequency of bupropion hydrochloride tablets in patients with renal impairment (glomerular filtration rate: less than 90 ml per min). bupropion and its metabolites are cleared renally and may accumulate in such patients to a greater extent than usual. monitor closely for adverse reactions that could indicate high bupropion or metabolite exposures [see dosage and administration ( 2.3), clinical pharmacology ( 12.3)] . in patients with moderate to severe hepatic impairment (child-pugh score: 7 to 15), the maximum dose of bupropion hydrochloride tablets is 75 mg daily. in patients with mild hepatic impairment (child-pugh score: 5 to 6), consider reducing the dose and/or frequency of dosing [see dosage and administration ( 2.2), clinical pharmacology ( 12.3)] . bupropion is not a controlled substance. humans controlled clinical trials conducted in normal volunteers, in subjects with a history of multiple drug abuse, and in depressed subjects showed some increase in motor activity and agitation/excitement, often typical of central stimulant activity. in a population of individuals experienced with drugs of abuse, a single oral dose of 400 mg of bupropion produced mild amphetamine-like activity as compared with placebo on the morphine-benzedrine subscale of the addiction research center inventories (arci) and a score greater than placebo but less than 15 mg of the schedule ii stimulant dextroamphetamine on the liking scale of the arci. these scales measure general feelings of euphoria and drug liking which are often associated with abuse potential. findings in clinical trials, however, are not known to reliably predict the abuse potential of drugs. nonetheless, evidence from single-dose trials does suggest that the recommended daily dosage of bupropion when administered orally in divided doses is not likely to be significantly reinforcing to amphetamine or cns stimulant abusers. however, higher doses (which could not be tested because of the risk of seizure) might be modestly attractive to those who abuse cns stimulant drugs. bupropion hydrochloride tablets are intended for oral use only. the inhalation of crushed tablets or injection of dissolved bupropion has been reported. seizures and/or cases of death have been reported when bupropion has been administered intranasally or by parenteral injection. animals studies in rodents and primates demonstrated that bupropion exhibits some pharmacologic actions common to psychostimulants. in rodents, it has been shown to increase locomotor activity, elicit a mild stereotyped behavior response, and increase rates of responding in several schedule-controlled behavior paradigms. in primate models assessing the positive-reinforcing effects of psychoactive drugs, bupropion was self-administered intravenously. in rats, bupropion produced amphetamine-like and cocaine-like discriminative stimulus effects in drug discrimination paradigms used to characterize the subjective effects of psychoactive drugs.

solco healthcare us, llc - levetiracetam (unii: 44yrr34555) (levetiracetam - unii:44yrr34555) - levetiracetam 250 mg - levetiracetam is indicated for the treatment of partial-onset seizures in patients 1 month of age and older. levetiracetam is indicated as adjunctive therapy for the treatment of myoclonic seizures in patients 12 years of age and older with juvenile myoclonic epilepsy. levetiracetam is indicated as adjunctive therapy for the treatment of primary generalized tonic-clonic seizures in patients 6 years of age and older with idiopathic generalized epilepsy. levetiracetam tablets are contraindicated in patients with a hypersensitivity to levetiracetam. reactions have included anaphylaxis and angioedema [see warnings and precautions (5.4) ]. there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (aeds), including levetiracetam, during pregnancy. encourage women who are taking levetiracetam during pregnancy to enroll in the north american antiepileptic drug (naaed) pregnancy registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org/. risk summary prolonged experience with levetiracetam in pregnant women has not identified a drug-associated risk of major birth defects or miscarriage, based on published literature, which includes data from pregnancy registries and reflects experience over two decades [see human data] . in animal studies, levetiracetam produced developmental toxicity (increased embryofetal and offspring mortality, increased incidences of fetal structural abnormalities, decreased embryofetal and offspring growth, neurobehavioral alterations in offspring) at doses similar to human therapeutic doses [see animal data] . in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. the background risk of major birth defects and miscarriage for the indicated population is unknown. clinical considerations levetiracetam blood levels may decrease during pregnancy [see warnings and precautions (5.11)] . physiological changes during pregnancy may affect levetiracetam concentration. decrease in levetiracetam plasma concentrations has been observed during pregnancy. this decrease is more pronounced during the third trimester. dose adjustments may be necessary to maintain clinical response. data human data while available studies cannot definitively establish the absence of risk, data from the published literature and pregnancy registries have not established an association with levetiracetam use during pregnancy and major birth defects or miscarriage. animal data when levetiracetam (0, 400, 1200, or 3600 mg/kg/day) was administered orally to pregnant rats during the period of organogenesis, reduced fetal weights and increased incidence of fetal skeletal variations were observed at the highest dose tested. there was no evidence of maternal toxicity. the no-effect dose for adverse effects on embryofetal developmental in rats (1200 mg/kg/day) is approximately 4 times the maximum recommended human dose (mrhd) of 3000 mg on a body surface area (mg/m2 ) basis. oral administration of levetiracetam (0, 200, 600, or 1800 mg/kg/day) to pregnant rabbits during the period of organogenesis resulted in increased embryofetal mortality and incidence of fetal skeletal variations at the mid and high dose and decreased fetal weights and increased incidence of fetal malformations at the high dose, which was associated with maternal toxicity. the no-effect dose for adverse effects on embryofetal development in rabbits (200 mg/kg/day) is approximately equivalent to the mrhd on a mg/m2 basis. oral administration of levetiracetam (0, 70, 350, or 1800 mg/kg/day) to female rats throughout pregnancy and lactation led to an increased incidence of fetal skeletal variations, reduced fetal body weight, and decreased growth in offspring at the mid and high doses and increased pup mortality and neurobehavioral alterations in offspring at the highest dose tested. there was no evidence of maternal toxicity. the no-effect dose for adverse effects on pre-and postnatal development in rats (70 mg/kg/day) is less than the mrhd on a mg/m2 basis. oral administration of levetiracetam to rats during the latter part of gestation and throughout lactation produced no adverse developmental or maternal effects at doses of up to 1800 mg/kg/day (6 times the mrhd on a mg/m2 basis). risk summary levetiracetam is excreted in human milk. there are no data on the effects of levetiracetam on the breastfed infant, or the effects on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for levetiracetam and any potential adverse effects on the breastfed infant from levetiracetam or from the underlying maternal condition. the safety and effectiveness of levetiracetam for the treatment of partial-onset seizures in patients 1 month to 16 years of age have been established [see clinical pharmacology (12.3) and clinical studies (14.1)] . the dosing recommendation in these pediatric patients varies according to age group and is weight-based [see dosage and administration (2.2)]. the safety and effectiveness of levetiracetam as adjunctive therapy for the treatment of myoclonic seizures in adolescents 12 years of age and older with juvenile myoclonic epilepsy have been established [see clinical studies (14.2)]. the safety and effectiveness of levetiracetam as adjunctive therapy for the treatment of primary generalized tonic-clonic seizures in pediatric patients 6 years of age and older with idiopathic generalized epilepsy have been established [see clinical studies (14.3)]. safety and effectiveness for the treatment of partial-onset seizures in pediatric patients below the age of 1 month; adjunctive therapy for the treatment of myoclonic seizures in pediatric patients below the age of 12 years; and adjunctive therapy for the treatment of primary generalized tonic-clonic seizures in pediatric patients below the age of 6 years have not been established. a 3-month, randomized, double-blind, placebo-controlled study was performed to assess the neurocognitive and behavioral effects of levetiracetam as adjunctive therapy in 98 (levetiracetam n=64, placebo n=34) pediatric patients, ages 4 to 16 years old, with partial seizures that were inadequately controlled. the target dose was 60 mg/kg/day. neurocognitive effects were measured by the leiter-r attention and memory (am) battery, which measures various aspects of a child's memory and attention. although no substantive differences were observed between the placebo and drug treated groups in the median change from baseline in this battery, the study was not adequate to assess formal statistical non-inferiority of the drug and placebo. the achenbach child behavior checklist (cbcl/6-18), a standardized validated tool used to assess a child’s competencies and behavioral/emotional problems, was also assessed in this study. an analysis of the cbcl/6-18 indicated on average a worsening in levetiracetam-treated patients in aggressive behavior, one of the eight syndrome scores [see warnings and precautions (5.1)] . juvenile animal toxicity data studies of levetiracetam in juvenile rats (dosed on postnatal days 4 through 52) and dogs (dosed from postnatal weeks 3 through 7) at doses of up to 1800 mg/kg/day (approximately 7 and 24 times, respectively, the maximum recommended pediatric dose of 60 mg/kg/day on a mg/m2 basis) did not demonstrate adverse effects on postnatal development. there were 347 subjects in clinical studies of levetiracetam that were 65 and over. no overall differences in safety were observed between these subjects and younger subjects. there were insufficient numbers of elderly subjects in controlled trials of epilepsy to adequately assess the effectiveness of levetiracetam in these patients. levetiracetam is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function [see clinical pharmacology (12.3)]. clearance of levetiracetam is decreased in patients with renal impairment and is correlated with creatinine clearance [see clinical pharmacology (12.3)] . dose adjustment is recommended for patients with impaired renal function and supplemental doses should be given to patients after dialysis [see dosage and administration (2.5)].

accord healthcare, inc. - sertraline hydrochloride (unii: uti8907y6x) (sertraline - unii:quc7nx6wmb) - sertraline 25 mg - sertraline hydrochloride tablets are indicated for the treatment of the following [see clinical studies (14)] : - major depressive disorder (mdd) - obsessive-compulsive disorder (ocd) - panic disorder (pd) - posttraumatic stress disorder (ptsd) - social anxiety disorder (sad) - premenstrual dysphoric disorder (pmdd) sertraline hydrochloride tablets are contraindicated in patients: - taking, or within 14 days of stopping, maois, (including the maois linezolid and intravenous methylene blue) because of an increased risk of serotonin syndrome [see warnings and precautions (5.2), drug interactions (7.1)] . - taking pimozide [see drug interactions (7.1)] . - with known hypersensitivity to sertraline (e.g., anaphylaxis, angioedema) [see adverse reactions (6.1, 6.2)]. pregnancy exposure registry there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy. healthcare providers should encourage patients to enroll by calling the national pregnancy registry for antidepressants at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/research/pregnancyregistry/antidepressants risk summary based on data from published observational studies, exposure to ssris, particularly in the month before delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage [see warnings and precautions (5.3) and clinical considerations]. overall, available published epidemiologic studies of pregnant women exposed to sertraline in the first trimester suggest no difference in major birth defect risk compared to the background rate for major birth defects in comparator populations. some studies have reported increases for specific major birth defects; however, these study results are inconclusive [see data] . there are clinical considerations regarding neonates exposed to ssris and snris, including sertraline hydrochloride, during the third trimester of pregnancy [see clinical considerations]. although no teratogenicity was observed in animal reproduction studies, delayed fetal ossification was observed when sertraline was administered during the period of organogenesis at doses less than the maximum recommended human dose (mrhd) in rats and doses 3.1 times the mrhd in rabbits on a mg/m 2 basis in adolescents. when sertraline was administered to female rats during the last third of gestation, there was an increase in the number of stillborn pups and pup deaths during the first four days after birth at the mrhd [see data] . the background risk of major birth defects and miscarriage for the indicated population are unknown. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. advise a pregnant woman of possible risks to the fetus when prescribing sertraline hydrochloride tablets. clinical considerations disease-associated maternal and/or embryo/fetal risk a prospective longitudinal study followed 201 pregnant women with a history of major depression who were euthymic taking antidepressants at the beginning of pregnancy. the women who discontinued antidepressants during pregnancy were more likely to experience a relapse of major depression than women who continued antidepressants. consider the risks of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum. maternal adverse reactions use of sertraline hydrochloride in the month before delivery may be associated with an increased risk of postpartum hemorrhage [see warnings and precautions (5.3)]. fetal/neonatal adverse reactions exposure to ssris and snris, including sertraline hydrochloride in late pregnancy may lead to an increased risk for neonatal complications requiring prolonged hospitalization, respiratory support, and tube feeding, and/or persistent pulmonary hypertension of the newborn (pphn). when treating a pregnant woman with sertraline hydrochloride during the third trimester, carefully consider both the potential risks and benefits of treatment. monitor neonates who were exposed to sertraline hydrochloride in the third trimester of pregnancy for pphn and drug discontinuation syndrome [see data]. data human data third trimester exposure neonates exposed to sertraline hydrochloride and other ssris or snris late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. these findings are based on post-marketing reports. such complications can arise immediately upon delivery. reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. these features are consistent with either a direct toxic effect of ssris and snris or, possibly, a drug discontinuation syndrome. in some cases, the clinical picture was consistent with serotonin syndrome [see warnings and precautions (5.2)] . exposure during late pregnancy to ssris may have an increased risk for persistent pulmonary hypertension of the newborn (pphn). pphn occurs in 1 to 2 per 1,000 live births in the general population and is associated with substantial neonatal morbidity and mortality. in a retrospective case-control study of 377 women whose infants were born with pphn and 836 women whose infants were born healthy, the risk for developing pphn was approximately six-fold higher for infants exposed to ssris after the 20 th week of gestation compared to infants who had not been exposed to antidepressants during pregnancy. a study of 831,324 infants born in sweden in 1997 to 2005 found a pphn risk ratio of 2.4 (95% ci 1.2 to 4.3) associated with patient-reported maternal use of ssris “in early pregnancy” and a pphn risk ratio of 3.6 (95% ci 1.2 to 8.3) associated with a combination of patient-reported maternal use of ssris “in early pregnancy” and an antenatal ssri prescription “in later pregnancy”. first trimester exposure the weight of evidence from epidemiologic studies of pregnant women exposed to sertraline in the first trimester suggest no difference in major birth defect risk compared to the background rate for major birth defects in pregnant women who were not exposed to sertraline. a meta-analysis of studies suggest no increase in the risk of total malformations (summary odds ratio=1.01, 95% ci=0.88 to 1.17) or cardiac malformations (summary odds ratio=0.93, 95% ci=0.70 to 1.23) among offspring of women with first trimester exposure to sertraline. an increased risk of congenital cardiac defects, specifically septal defects, the most common type of congenital heart defect, was observed in some published epidemiologic studies with first trimester sertraline exposure; however, most of these studies were limited by the use of comparison populations that did not allow for the control of confounders such as the underlying depression and associated conditions and behaviors, which may be factors associated with increased risk of these malformations. animal data reproduction studies have been performed in rats and rabbits at doses up to 80 mg/kg/day and  40 mg/kg/day, respectively. these doses correspond to approximately 3.1 times the maximum recommended human dose (mrhd) of 200 mg/day on a mg/m 2 basis in adolescents. there was no evidence of teratogenicity at any dose level. when pregnant rats and rabbits were given sertraline during the period of organogenesis, delayed ossification was observed in fetuses at doses of 10 mg/kg (0.4 times the mrhd on a mg/m 2 basis) in rats and 40 mg/kg (3.1 times the mrhd on a mg/m 2 basis) in rabbits. when female rats received sertraline during the last third of gestation and throughout lactation, there was an increase in stillborn pups and pup deaths during the first 4 days after birth. pup body weights were also decreased during the first four days after birth. these effects occurred at a dose of 20 mg/kg (0.8 times the mrhd on a mg/m 2 basis). the no effect dose for rat pup mortality was 10 mg/kg (0.4 times the mrhd on a mg/m 2 basis). the decrease in pup survival was shown to be due to in utero exposure to sertraline. the clinical significance of these effects is unknown. risk summary available data from published literature demonstrate low levels of sertraline and its metabolites in human milk [see data] . there are no data on the effects of sertraline on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for sertraline hydrochloride and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition. data in a published pooled analysis of 53 mother-infant pairs, exclusively human milk-fed infants had an average of 2% (range 0% to 15%) of the sertraline serum levels measured in their mothers. no adverse reactions were observed in these infants. the safety and efficacy of sertraline hydrochloride have been established in the treatment of ocd in pediatric patients aged 6 to 17 [see adverse reactions (6.1), clinical pharmacology (12.3), clinical studies (14.2)] . safety and effectiveness in pediatric patients in patients with ocd below the age of 6 have not been established. safety and effectiveness have not been established in pediatric patients for indications other than ocd. two placebo-controlled trials were conducted in pediatric patients with mdd, but the data were not sufficient to support an indication for use in pediatric patients. monitoring pediatric patients treated with sertraline hydrochloride monitor all patients being treated with antidepressants for clinical worsening, suicidal thoughts, and unusual changes in behavior, especially during the initial few months of treatment, or at times of dose increases or decreases [see boxed warning, warnings and precautions (5.1)] . decreased appetite and weight loss have been observed with the use of ssris. monitor weight and growth in pediatric patients treated with an ssri such as sertraline hydrochloride . weight loss in studies in pediatric patients with mdd in a pooled analysis of two 10-week, double-blind, placebo-controlled, flexible dose (50 mg to 200 mg) outpatient trials for mdd (n=373), there was a difference in weight change between sertraline hydrochloride and placebo of roughly 1 kg, for both children (ages 6 to 11) and adolescents (ages 12 to 17), in both age groups representing a slight weight loss for the sertraline hydrochloride group compared to a slight gain for the placebo group. for children, about 7% of the sertraline hydrochloride-treated patients had a weight loss greater than 7% of body weight compared to 0% of the placebo-treated patients; for adolescents, about 2% of sertraline hydrochloride-treated patients had a weight loss > 7% of body weight compared to about 1% of placebo-treated patients. a subset of patients who completed the randomized controlled trials in patients with mdd (sertraline hydrochloride n=99, placebo n=122) were continued into a 24-week, flexible-dose, open-label, extension study. those subjects who completed 34 weeks of sertraline hydrochloride treatment (10 weeks in a placebo-controlled trial + 24 weeks open-label, n=68) had weight gain that was similar to that expected using data from age-adjusted peers. however, there are no studies that directly evaluate the long-term effects of sertraline hydrochloride on the growth, development, and maturation in pediatric patients. juvenile animal data a study conducted in juvenile rats at clinically relevant doses showed delay in sexual maturation, but there was no effect on fertility in either males or females. in this study in which juvenile rats were treated with oral doses of sertraline at 0, 10, 40 or 80 mg/kg/day from postnatal day 21 to 56, a delay in sexual maturation was observed in males treated with 80 mg/kg/day and females treated with doses ≥10 mg/kg/day. there was no effect on male and female reproductive endpoints or neurobehavioral development up to the highest dose tested (80 mg/kg/day), except a decrease in auditory startle response in females at 40 and 80 mg/kg/day at the end of treatment but not at the end of the drug-free period. the highest dose of 80 mg/kg/day produced plasma levels (auc) of sertraline 5 times those seen in pediatric patients (6 to 17 years of age) receiving the maximum recommended dose of sertraline (200 mg/day). of the total number of patients in clinical studies of sertraline hydrochloride in patients with mdd, ocd, pd, ptsd, sad and pmdd, 797 (17%) were ≥ 65 years old, while 197 (4%) were ≥ 75 years old. no overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. in general, dose selection for an elderly patient should be conservative, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. in 354 geriatric subjects treated with sertraline hydrochloride in mdd placebo-controlled trials, the overall profile of adverse reactions was generally similar to that shown in table 3  [see adverse reactions (6.1)], except for tinnitus, arthralgia with an incidence of at least 2% and at a rate greater than placebo in geriatric patients. snris and ssris, including sertraline hydrochloride, have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse reaction [see warnings and precautions (5.8) ] . the recommended dosage in patients with mild hepatic impairment (child-pugh score 5 or 6) is half the recommended dosage due to increased exposure in this patient population. the use of sertraline hydrochloride in patients with moderate (child-pugh score 7 to 10) or severe hepatic impairment (child-pugh score 10 to 15) is not recommended, because sertraline hydrochloride is extensively metabolized, and the effects of sertraline hydrochloride in patients with moderate and severe hepatic impairment have not been studied [see dosage and administration (2.4), clinical pharmacology (12.3)] . no dose adjustment is needed in patients with mild to severe renal impairment. sertraline exposure does not appear to be affected by renal impairment [see clinical pharmacology (12.3)] . sertraline hydrochloride tablets contain sertraline, which is not a controlled substance. in a placebo-controlled, double-blind, randomized study of the comparative abuse liability of sertraline hydrochloride, alprazolam, and d-amphetamine in humans, sertraline hydrochloride did not produce the positive subjective effects indicative of abuse potential, such as euphoria or drug liking, that were observed with the other two drugs.

have not reported a clear association with zolpidem and major birth defects [see data]. oral administration of zolpidem to pregnant rats and rabbits did not indicate a risk for adverse effects on fetal development at clinically relevant doses [see data]. the estimated background risk of major birth defects and miscarriage for the indicated populations are unknown. all pregnancies have a background risk of birth defect, loss, or other adverse outcomes. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. clinical considerations fetal/neonatal adverse reactions zolpidem crosses the placenta and may produce respiratory depression and sedation in neonates. monitor neonates exposed to zolpidem during pregnancy and labor for signs of excess sedation, hypotonia, and respiratory depression and manage accordingly. data human data published data from observational studies, birth registries, and case reports on the use of zolpidem during pregnancy do not report a clear association with zolpidem and major birth defects. there are limited postmarketing reports of severe to moderate cases of respiratory depression that occurred after birth in neonates whose mothers had taken zolpidem during pregnancy. these cases required artificial ventilation or intratracheal intubation. the majority of neonates recovered within hours to a few weeks after birth once treated. zolpidem has been shown to cross the placenta. animal data oral administration of zolpidem to pregnant rats during the period of organogenesis at 4, 20, and 100 mg base/kg/day, which are approximately 5, 25, and 120 times the maximum recommended human dose (mrhd) of 10 mg/day (8 mg zolpidem base) based on mg/m 2  body surface area, caused delayed fetal development (incomplete fetal skeletal ossification) at maternally toxic (ataxia) doses 25 and 120 times the mrhd based on mg/m 2  body surface area. oral administration of zolpidem to pregnant rabbits during the period of organogenesis at 1, 4, and 16 mg base/kg/day, which are approximately 2.5, 10, and 40 times the mrhd of 10 mg/day (8 mg zolpidem base) based on mg/m 2 body surface area caused embryo-fetal death and delayed fetal development (incomplete fetal skeletal ossification) at a maternally toxic (decreased body weight gain) dose 40 times the mrhd based on mg/m 2 body surface area. oral administration of zolpidem to pregnant rats from day 15 of gestation through lactation at 4, 20, and 100 mg base/kg/day, which are approximately 5, 25, and 120 times the mrhd of 10 mg/day (8 mg zolpidem base) based on mg/m 2 body surface area, delayed offspring growth and decreased survival at doses 25 and 120 times, respectively, the mrhd based on mg/m2 body surface area. risk summary limited data from published literature report the presence of zolpidem in human milk. there are reports of excess sedation in infants exposed to zolpidem through breastmilk [see clinical considerations]. there is no information on the effects of zolpidem on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for zolpidem and any potential adverse effects on the breastfed infant from zolpidem or from the underlying maternal condition. clinical considerations infants exposed to zolpidem through breastmilk should be monitored for excess sedation, hypotonia, and respiratory depression. a lactating woman may consider interrupting breastfeeding and pumping and discarding breast milk during treatment and for 23 hours (approximately 5 elimination half-lives) after zolpidem administration in order to minimize drug exposure to a breast fed infant. zolpidem is not recommended for use in children. safety and effectiveness of zolpidem in pediatric patients below the age of 18 years have not been established. in an 8-week study in pediatric patients (aged 6 to 17 years) with insomnia associated with attention-deficit/hyperactivity disorder (adhd) an oral solution of zolpidem tartrate dosed at 0.25 mg/kg at bedtime did not decrease sleep latency compared to placebo. psychiatric and nervous system disorders comprised the most frequent (>5%) treatment emergent adverse reactions observed with zolpidem versus placebo and included dizziness (23.5% vs. 1.5%), headache (12.5% vs. 9.2%), and hallucinations were reported in 7% of the pediatric patients who received zolpidem; none of the pediatric patients who received placebo reported hallucinations [see warnings and precautions ( 5.5)] . ten patients on zolpidem (7.4%) discontinued treatment due to an adverse reaction. a total of 154 patients in u.s. controlled clinical trials and 897 patients in non-u.s. clinical trials who received zolpidem were ≥60 years of age. for a pool of u.s. patients receiving zolpidem at doses of ≤10 mg or placebo, there were three adverse reactions occurring at an incidence of at least 3% for zolpidem and for which the zolpidem incidence was at least twice the placebo incidence (i.e., they could be considered drug related). a total of 30/1,959 (1.5%) non-u.s. patients receiving zolpidem reported falls, including 28/30 (93%) who were ≥70 years of age. of these 28 patients, 23 (82%) were receiving zolpidem doses >10 mg. a total of 24/1,959 (1.2%) non-u.s. patients receiving zolpidem reported confusion, including 18/24 (75%) who were ≥70 years of age. of these 18 patients, 14 (78%) were receiving zolpidem doses >10 mg. the dose of zolpidem tartrate tablets in elderly patients is 5 mg to minimize adverse effects related to impaired motor and/or cognitive performance and unusual sensitivity to sedative/hypnotic drugs [see warnings and precautions ( 5.2 ) ]. women clear zolpidem tartrate from the body at a lower rate than men. c max and auc parameters of zolpidem were approximately 45% higher at the same dose in female subjects compared with male subjects. given the higher blood levels of zolpidem tartrate in women compared to men at a given dose, the recommended initial dose of zolpidem for adult women is 5 mg, and the recommended dose for adult men is 5 or 10 mg. in geriatric patients, clearance of zolpidem is similar in men and women. the recommended dose of zolpidem in geriatric patients is 5 mg regardless of gender. the recommended dose of zolpidem tartrate tablets in patients with mild to moderate hepatic impairment is 5 mg once daily immediately before bedtime. avoid zolpidem tartrate tablets use in patients with severe hepatic impairment as it may contribute to encephalopathy [see dosage and administration ( 2.2), warnings and precautions ( 5.8), clinical pharmacology ( 12.3)]. zolpidem tartrate is classified as a schedule iv controlled substance by federal regulation. abuse and addiction are separate and distinct from physical dependence and tolerance. abuse is characterized by misuse of the drug for non-medical purposes, often in combination with other psychoactive substances. tolerance is a state of adaptation in which exposure to a drug induces changes that result in a diminution of one or more of the drug effects over time. tolerance may occur to both desired and undesired effects of drugs and may develop at different rates for different effects. addiction is a primary, chronic, neurobiological disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. its characterized by behaviors that include one or more of the following: impaired control over drug use, compulsive use, continued use despite harm, and craving. drug addiction is a treatable disease, using a multidisciplinary approach, but relapse is common. studies of abuse potential in former drug abusers found that the effects of single doses of zolpidem tartrate 40 mg were similar, but not identical, to diazepam 20 mg, while zolpidem tartrate 10 mg was difficult to distinguish from placebo. because persons with a history of addiction to, or abuse of, drugs or alcohol are at increased risk for misuse, abuse and addiction of zolpidem, they should be monitored carefully when receiving zolpidem or any other hypnotic. use of zolpidem tartrate tablets may lead to the development of physical and/or psychological dependence. the risk of dependence increases with dose and duration of treatment. the risk of abuse and dependence is also greater in patients with a history of alcohol or drug abuse. zolpidem tartrate tablets should be used with extreme caution in patients with current or past alcohol or drug abuse. physical dependence is a state of adaptation that is manifested by a specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level of the drug, and/or administration of an antagonist. sedative/hypnotics have produced withdrawal signs and symptoms following abrupt discontinuation. these reported symptoms range from mild dysphoria and insomnia to a withdrawal syndrome that may include abdominal and muscle cramps, vomiting, sweating, tremors, and convulsions and delirium. the following adverse events, which are considered to meet the dsm-iii-r criteria for uncomplicated sedative/hypnotic withdrawal, were reported during clinical trials with zolpidem tartrate tablets following placebo substitution occurring within 48 hours following last zolpidem treatment: fatigue, nausea, flushing, lightheadedness, uncontrolled crying, emesis, stomach cramps, panic attack, nervousness and abdominal discomfort. these reported adverse events occurred at an incidence of 1% or less. however, available data cannot provide a reliable estimate of the incidence, if any, of dependence during treatment at recommended doses. there have been postmarketing reports of abuse, dependence and withdrawal with zolpidem.

the north american drug pregnancy registry can be found at http://www.aedpregnancyregistry.org/. risk summary trokendi xr can cause fetal harm when administered to a pregnant woman. data from pregnancy registries indicate that infants exposed to topiramate in utero have increased risk for cleft lip and/or cleft palate (oral clefts) and for being small for gestational age (sga) [see human data] . sga has been observed at all doses and appears to be dose-dependent. the prevalence of sga is greater in infants of women who received higher doses of topiramate during pregnancy. in addition, the prevalence of sga in infants of women who continued topiramate use until later in pregnancy is higher compared to the prevalence in infants of women who stopped topiramate use before the third trimester. in multiple animal species, topiramate demonstrated developmental toxicity, including increased incidences of fetal malformations, in the absence of maternal toxicity at clinically relevant doses [see animal data] . in the u.s. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2-4% and 15-20%, respectively. clinical considerations fetal/neonatal adverse reactions consider the benefits and risks of topiramate when prescribing this drug to women of childbearing potential, particularly when topiramate is considered for a condition not usually associated with permanent injury or death. because of the risk of oral clefts to the fetus, which occur in the first trimester of pregnancy before many women know they are pregnant, all women of childbearing potential should be informed of the potential risk to the fetus from exposure to topiramate. women who are planning a pregnancy should be counseled regarding the relative risks and benefits of topiramate use during pregnancy, and alternative therapeutic options should be considered for these patients. labor or delivery although the effect of topiramate on labor and delivery in humans has not been established, the development of topiramate-induced metabolic acidosis in the mother and/or in the fetus might affect the fetus' ability to tolerate labor. trokendi xr treatment can cause metabolic acidosis [see warnings and precautions (5.4)] . the effect of topiramate-induced metabolic acidosis has not been studied in pregnancy; however, metabolic acidosis in pregnancy (due to other causes) can cause decreased fetal growth, decreased fetal oxygenation, and fetal death, and may affect the fetus' ability to tolerate labor. pregnant patients should be monitored for metabolic acidosis and treated as in the nonpregnant state [see warnings and precautions (5.4)] . newborns of mothers treated with trokendi xr should be monitored for metabolic acidosis because of transfer of topiramate to the fetus and possible occurrence of transient metabolic acidosis following birth. based on limited information, topiramate has also been associated with pre-term labor and premature delivery. data human data data from pregnancy registries indicate an increased risk of oral clefts in infants exposed to topiramate during the first trimester of pregnancy. in the naaed pregnancy registry, the prevalence of oral clefts among topiramate-exposed infants (1.1%) was higher than the prevalence of infants exposed to reference aeds (0.36%), or the prevalence in infants of mothers without epilepsy and without exposure to aeds (0.12%). it was also higher than the background prevalence in united states (0.17%) as estimated by the centers for disease control and prevention (cdc). the relative risk of oral clefts in topiramate-exposed pregnancies in the naaed pregnancy registry was 9.6 (95% confidence interval=[ci] 4.0-23.0) as compared to the risk in a background population of untreated women. the uk epilepsy and pregnancy register reported a prevalence of oral clefts among infants exposed to topiramate monotherapy (3.2%) that was 16 times higher than the background rate in the uk (0.2%). data from the naaed pregnancy registry and a population-based birth registry cohort indicate that exposure to topiramate in utero is associated with an increased risk of sga newborns (birth weight <10th percentile). in the naaed pregnancy registry, 19.7% of topiramate-exposed newborns were sga compared to 7.9% of newborns exposed to a reference aed, and 5.4% of newborns of mothers without epilepsy and without aed exposure. in the medical birth registry of norway (mbrn), a population-based pregnancy registry, 25% of newborns in the topiramate monotherapy exposure group were sga compared to 9% in the comparison group who were unexposed to aeds. the long-term consequences of the sga findings are not known. animal data when topiramate (0, 20, 100, or 500 mg/kg/day) was administered orally to pregnant mice during the period of organogenesis, incidences of fetal malformations (primarily craniofacial defects) were increased at all doses. fetal body weights and skeletal ossification were reduced at the highest dose tested in conjunction with decreased maternal body weight gain. a no-effect dose for embryofetal developmental toxicity in mice was not identified. the lowest dose tested, which was associated with an increased incidence of malformations, is less than the maximum recommended human dose (mrhd) for epilepsy (400 mg/day) or migraine (100 mg/day) on a body surface area (mg/m 2 ) basis. in pregnant rats administered topiramate (0, 20, 100, and 500 mg/kg/day or 0, 0.2, 2.5, 30, and 400 mg/kg/day) orally during the period of organogenesis, the frequency of limb malformations (ectrodactyly, micromelia, and amelia) was increased in fetuses at 400 and 500 mg/kg/day. embryotoxicity (reduced fetal body weights, increased incidences of structural variations) was observed at doses as low as 20 mg/kg/day. clinical signs of maternal toxicity were seen at 400 mg/kg/day and above, and maternal body weight gain was reduced at doses of 100 mg/kg/day or greater. the no-effect dose (2.5 mg/kg/day) for embryofetal developmental toxicity in rats is less than the mrhd for epilepsy or migraine on a mg/m 2 basis. in pregnant rabbits administered topiramate (0, 20, 60, and 180 mg/kg/day or 0, 10, 35, and 120 mg/kg/day) orally during organogenesis, embryofetal mortality was increased at 35 mg/kg/day and an increased incidence of fetal malformations (primarily rib and vertebral malformations) was observed at 120 mg/kg/day. evidence of maternal toxicity (decreased body weight gain, clinical signs, and/or mortality) was seen at 35 mg/kg/day and above. the no-effect dose (20 mg/kg/day) for embryofetal developmental toxicity in rabbits is equivalent to the mrhd for epilepsy and approximately 4 times the mrhd for migraine on a mg/m 2 basis. when topiramate (0, 0.2, 4, 20, and 100 mg/kg/day or 0, 2, 20, and 200 mg/kg/day) was administered orally to female rats during the latter part of gestation and throughout lactation, offspring exhibited decreased viability and delayed physical development at 200 mg/kg/day and reductions in pre-and/or postweaning body weight gain at 2 mg/kg/day and above. maternal toxicity (decreased body weight gain, clinical signs) was evident at 100 mg/kg/day or greater. in a rat embryofetal development study which included postnatal assessment of offspring, oral administration of topiramate (0, 0.2, 2.5, 30, and 400 mg/kg/day) to pregnant animals during the period of organogenesis resulted in delayed physical development in offspring at 400 mg/kg/day and persistent reductions in body weight gain in offspring at 30 mg/kg/day and higher. the no-effect dose (0.2 mg/kg/day) for pre- and postnatal developmental toxicity is less than the mrhd for epilepsy or migraine on a mg/m 2 basis. risk summary topiramate is excreted in human milk [see data]. the effects of topiramate on milk production are unknown. diarrhea and somnolence have been reported in breastfed infants whose mothers receive topiramate treatment. the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for trokendi xr and any potential adverse effects on the breastfed infant from trokendi xr or from the underlying maternal condition. data limited data from 5 women with epilepsy treated with topiramate during lactation showed drug levels in milk similar to those in maternal plasma. contraception women of childbearing potential who are not planning a pregnancy should use effective contraception because of the risks to the fetus of oral clefts and of being small for gestational age [see drug interactions (7.5) and use in specific populations (8.1)] . seizures in pediatric patients 6 years of age and older the safety and effectiveness of trokendi xr ® for treatment of partial onset seizures, primary generalized tonic-clonic seizures, or lennox-gastaut syndromes in pediatric patients at least 6 years of age is based on controlled trials with immediate-release topiramate [see adverse reactions (6.1), clinical studies (14.2, 14.3)] . the adverse reactions in pediatric patients treated for partial onset seizure, primary generalized tonic-clonic seizures, or lennox-gastaut syndrome are similar to those seen in adults [see warnings and precautions (5) and adverse reactions (6)] . these include, but are not limited to: - oligohydrosis and hyperthermia [see warnings and precautions (5.3)] - dose-related increased incidence of metabolic acidosis [see warnings and precautions (5.4)] - dose-related increased incidence of hyperammonemia [see warnings and precautions (5.13)] not recommended for pediatric patients younger than 6 years of age the safety and effectiveness of trokendi xr for treatment of partial-onset seizures, primary generalized tonic-clonic seizures, or lennox-gastaut syndromes in pediatric patients younger than 6 years of age has not been established. because the capsule must be swallowed whole, and may not be sprinkled on food, crushed or chewed, trokendi xr ® is recommended only for children age 6 or older. the following pediatric use information for adjunctive treatment for partial onset epilepsy in infants and toddlers (1 to 24 months) is based on studies conducted with immediate-release topiramate, which failed to demonstrate efficacy. safety and effectiveness of immediate-release topiramate in patients below the age of 2 years have not been established for the adjunctive therapy treatment of partial onset seizures, primary generalized tonic-clonic seizures, or seizures associated with lennox-gastaut syndrome. in a single randomized, double-blind, placebo-controlled investigational trial, the efficacy, safety, and tolerability of immediate-release topiramate oral liquid and sprinkle formulations as an adjunct to concurrent antiepileptic drug therapy in pediatric patients 1 to 24 months of age with refractory partial-onset seizures were assessed. after 20 days of double-blind treatment, immediate-release topiramate (at fixed doses of 5, 15, and 25 mg/kg per day) did not demonstrate efficacy compared with placebo in controlling seizures. in general, the adverse reaction profile for immediate-release topiramate in this population was similar to that of older pediatric patients, although results from the above controlled study, and an open-label, long-term extension study in these pediatric patients 1 to 24 months old suggested some adverse reactions not previously observed in older pediatric patients and adults; i.e., growth/length retardation, certain clinical laboratory abnormalities, and other adverse reactions that occurred with a greater frequency and/or greater severity than had been recognized previously from studies in older pediatric patients or adults for various indications. these very young pediatric patients appeared to experience an increased risk for infections (any topiramate dose 12%, placebo 0%) and of respiratory disorders (any topiramate dose 40%, placebo 16%). the following adverse reactions were observed in at least 3% of patients on immediate-release topiramate and were 3% to 7% more frequent than in patients on placebo: viral infection, bronchitis, pharyngitis, rhinitis, otitis media, upper respiratory infection, cough, and bronchospasm. a generally similar profile was observed in older pediatric patients [see adverse reactions (6.1)]. immediate-release topiramate resulted in an increased incidence of patients with increased creatinine (any topiramate dose 5%, placebo 0%), bun (any topiramate dose 3%, placebo 0%), and protein (any topiramate dose 34%, placebo 6%), and an increased incidence of decreased potassium (any topiramate dose 7%, placebo 0%). this increased frequency of abnormal values was not dose related. creatinine was the only analyte showing a noteworthy increased incidence (topiramate 25 mg/kg/day 5%, placebo 0%) of a markedly abnormal increase [see adverse reactions (6.1)] . the significance of these findings is uncertain. immediate-release topiramate treatment also produced a dose-related increase in the percentage of patients who had a shift from normal at baseline to high/increased (above the normal reference range) in total eosinophil count at the end of treatment. the incidence of these abnormal shifts was 6 % for placebo, 10% for 5 mg/kg/day, 9% for 15 mg/kg/day, 14% for 25 mg/kg/day, and 11% for any topiramate dose [see adverse reactions (6.1)] . there was a mean dose-related increase in alkaline phosphatase. the significance of these findings is uncertain. topiramate produced a dose-related increased incidence of hyperammonemia [see warnings and precautions (5.13)] . treatment with immediate-release topiramate for up to 1 year was associated with reductions in z scores for length, weight, and head circumference [see warnings and precautions (5.4) and adverse reactions (6)] . in open-label, uncontrolled experience, increasing impairment of adaptive behavior was documented in behavioral testing over time in this population. there was a suggestion that this effect was dose-related. however, because of the absence of an appropriate control group, it is not known if this decrement in function was treatment related or reflects the patient's underlying disease (e.g., patients who received higher doses may have more severe underlying disease) [see warnings and precautions (5.7)] . in this open-label, uncontrolled study, the mortality was 37 deaths/1000 patient years. it is not possible to know whether this mortality rate is related to immediate-release topiramate treatment, because the background mortality rate for a similar, significantly refractory, young pediatric population (1 month to 24 months) with partial epilepsy is not known. other pediatric studies topiramate treatment produced a dose-related increased shift in serum creatinine from normal at baseline to an increased value at the end of 4 months treatment in adolescent patients (ages 12 years to 16 years) in a double-blind, placebo-controlled study [see adverse reactions (6.1)] . a one-year, active-controlled, open-label study with blinded assessments of bone mineral density (bmd) and growth in pediatric patients 4 to 15 years of age, including 63 patients with recent or new onset of epilepsy, was conducted to assess effects of immediate-release topiramate (n=28, 6-15 years of age) versus levetiracetam (n=35, 4-15 years of age) monotherapy on bone mineralization and on height and weight, which reflect growth. effects on bone mineralization were evaluated via dual-energy x-ray absorptiometry and blood markers. table 8 summarizes effects of immediate-release topiramate at 12 months for key safety outcomes including bmd, height, height velocity, and weight. all least square mean values for immediate-release topiramate and the comparator were positive. therefore, the least square mean treatment differences shown reflect an immediate-release topiramate-induced attenuation of the key safety outcomes. statistically significant effects were observed for decreases in bmd (and bone mineral content) in lumbar spine and total body less head and in weight. subgroup analyses according to age demonstrated similar negative effects for all key safety outcomes (i.e., bmd, height, weight). metabolic acidosis (serum bicarbonate <20 meq/l) was observed in all immediate-release topiramate-treated patients at some time in the study [see warnings and precautions (5.4)]. over the whole study, 76% more immediate-release topiramate-treated patients experienced persistent metabolic acidosis (i.e., 2 consecutive visits with or final serum bicarbonate < 20 meq/l) compared to levetiracetam-treated patients. over the whole study, 35% more immediate-release topiramate-treated patients experienced a markedly abnormally low serum bicarbonate (i.e., absolute value <17 meq/l and ≥ 5meq/l decrease from pre-treatment), indicating the frequency of more severe metabolic acidosis, compared to levetiracetam-treated patients. the decrease in bmd at 12 months was correlated with decreased serum bicarbonate, suggesting that metabolic acidosis was at least a partial factor contributing to this adverse effect on bmd. immediate-release topiramate-treated patients exhibited an increased risk for developing an increased serum creatinine and an increased serum glucose above the normal reference range compared to control patients. preventive treatment of migraine in pediatric patients 12 to 17 years of age safety and effectiveness of topiramate for the preventive treatment of migraine was studied in 5 double-blind, randomized, placebo-controlled, parallel-group trials in a total of 219 pediatric patients, at doses of 50 mg/day to 200 mg/day, or 2 to 3 mg/kg/day. these comprised a fixed dose study in 103 pediatric patients 12 to 17 years of age [see clinical studies (14.4)], a flexible dose (2 to 3 mg/kg/day), placebo-controlled study in 157 pediatric patients 6 to 16 years of age (including 67 pediatric patients 12 to 16 years of age), and a total of 49 pediatric patients 12 to 17 years of age in 3 studies for the preventive treatment of migraine primarily in adults. open-label extension phases of 3 studies enabled evaluation of long-term safety for up to 6 months after the end of the double-blind phase. efficacy of topiramate for the preventive treatment of migraine in pediatric patients 12 to 17 years of age is demonstrated for a 100 mg daily dose in study 3 [see clinical studies (14.4)] . efficacy of topiramate (2 to 3 mg/kg/day) for the preventive treatment of migraine was not demonstrated in a placebo-controlled trial of 157 pediatric patients (6 to 16 years of age) that included treatment of 67 pediatric patients 12 to 16 years of age) for 20 weeks. in the pediatric trials (12 to 17 years of age) in which patients were randomized to placebo or a fixed daily dose of immediate-release topiramate, the most common adverse reactions with immediate-release topiramate that were seen at an incidence higher (≥5%) than in the placebo group were: paresthesia, upper respiratory tract infection, anorexia, and abdominal pain [see adverse reactions (6.1)] . the most common cognitive adverse reaction in pooled double-blind studies in pediatric patients 12 to 17 years of age was difficulty with concentration/attention [see warnings and precautions (5.7)] . markedly abnormally low serum bicarbonate values indicative of metabolic acidosis were reported in topiramate-treated pediatric migraine patients [see warnings and precautions (5.4)] . in topiramate-treated pediatric patients (12 to 17 years of age) compared to placebo-treated patients, abnormally increased results were more frequent for creatinine, bun, uric acid, chloride, ammonia, total protein, and platelets. abnormally decreased results were observed with topiramate vs placebo treatment for phosphorus and bicarbonate [see adverse reactions (6.1)] . notable changes (increases and decreases) from baseline in systolic blood pressure, diastolic blood pressure, and pulse that were observed occurred more commonly in pediatric patients treated with topiramate compared to pediatric patients treated with placebo [see clinical pharmacology (12.2)] . preventive treatment of migraine in pediatric patients 6 to 11 years of age safety and effectiveness in pediatric patients below the age of 12 years have not been established for the preventive treatment of migraine. in a double-blind study in 90 pediatric patients 6 to 11 years of age (including 59 topiramate-treated and 31 placebo patients), the adverse reaction profile was generally similar to that seen in pooled double-blind studies of pediatric patients 12 to 17 years of age. the most common adverse reactions that occurred in immediate-release topiramate-treated pediatric patients 6 to 11 years of age, and at least twice as frequently than placebo, were gastroenteritis (12% topiramate, 6% placebo), sinusitis (10% topiramate, 3% placebo), weight loss (8% topiramate, 3% placebo) and paresthesia (7% topiramate, 0% placebo). difficulty with concentration/attention occurred in 3 topiramate-treated patients (5%) and 0 placebo-treated patients. the risk for cognitive adverse reactions was greater in younger patients (6 to 11 years of age) than in older patients (12 to 17 years of age) [see warnings and precautions (5.7)] . juvenile animal studies when topiramate (30, 90, and 300 mg/kg/day) was administered orally to rats during the juvenile period of development (postnatal days 12 to 50), bone growth plate thickness was reduced in males at the highest dose, which is approximately 5-8 times the maximum recommended pediatric dose (9 mg/kg/day) on a body surface area (mg/m 2 ) basis. clinical studies of immediate-release topiramate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently than younger subjects. dosage adjustment may be necessary for elderly with creatinine clearance less than 70 ml/min/1.73 m 2 . estimate gfr should be measured prior to dosing [see dosage and administration (2.5) and clinical pharmacology (12.3)] . the clearance of topiramate is reduced in patients with moderate (creatinine clearance 30 to 69 ml/min/1.73m 2 ) and severe (creatinine clearance less than 30 ml/min/1.73m 2 ) renal impairment. a dosage adjustment is recommended in patients with moderate or severe renal impairment [see dosage and administration (2.5) and clinical pharmacology (12.3)] . topiramate is cleared by hemodialysis at a rate that is 4 to 6 times greater than in a normal individual. a dosage adjustment may be required [see dosage and administration (2.6) and clinical pharmacology (12.3)] .

are indicated for the preventive treatment of migraine in patients 12 years of age and older. none. pregnancy exposure registry there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (aeds), such as topiramate, during pregnancy. patients should be encouraged to enroll in the north american antiepileptic drug (naaed) pregnancy registry if they become pregnant. this registry is collecting information about the safety of antiepileptic drugs during pregnancy. to enroll, patients can call the toll-free number 1-888-233-2334. information about the north american drug pregnancy registry can be found at http://www.aedpregnancyregistry.org/. risk summary topiramate extended-release can cause fetal harm when administered to a pregnant woman. data from pregnancy registries indicate that infants exposed to topiramate in utero have increased risk of major congenital malformations, including but not limited to cleft lip and/or cleft palate (oral clefts), and of being small for gestational age (sga) [see human data] . sga has been observed at all doses and appears to be dose-dependent. the prevalence of sga is greater in infants of women who received higher doses of topiramate during pregnancy. in addition, the prevalence of sga in infants of women who continued topiramate use until later in pregnancy is higher compared to the prevalence in infants of women who stopped topiramate use before the third trimester. in multiple animal species, topiramate demonstrated developmental toxicity, including increased incidences of fetal malformations, in the absence of maternal toxicity at clinically relevant doses [see animal data] . all pregnancies have a background risk of birth defects, loss, or other adverse outcomes. the estimated background risk of major birth defects and miscarriage for the indicated population is unknown. in the u.s. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2% to 4% and 15% to 20%, respectively. clinical considerations fetal/neonatal adverse reactions consider the benefits and risks of topiramate when prescribing this drug to women of childbearing potential, particularly when topiramate is considered for a condition not usually associated with permanent injury or death. because of the risk of oral clefts to the fetus, which occur in the first trimester of pregnancy before many women know they are pregnant, all women of childbearing potential should be informed of the potential risk to the fetus from exposure to topiramate. women who are planning a pregnancy should be counseled regarding the relative risks and benefits of topiramate use during pregnancy, and alternative therapeutic options should be considered for these patients. labor or delivery although the effect of topiramate on labor and delivery in humans has not been established, the development of topiramate-induced metabolic acidosis in the mother and/or in the fetus might affect the fetus' ability to tolerate labor. topiramate extended-release treatment can cause metabolic acidosis [see warnings and precautions (5.4)] . the effect of topiramate-induced metabolic acidosis has not been studied in pregnancy; however, metabolic acidosis in pregnancy (due to other causes) can cause decreased fetal growth, decreased fetal oxygenation, and fetal death, and may affect the fetus' ability to tolerate labor. pregnant patients should be monitored for metabolic acidosis and treated as in the nonpregnant state [see warnings and precautions (5.4)] . newborns of mothers treated with topiramate extended-release should be monitored for metabolic acidosis because of transfer of topiramate to the fetus and possible occurrence of transient metabolic acidosis following birth. based on limited information, topiramate has also been associated with pre-term labor and premature delivery. data human data data from pregnancy registries indicate an increased risk of major congenital malformations, including but not limited to oral clefts in infants exposed to topiramate during the first trimester of pregnancy. other than oral clefts, no specific pattern of major congenital malformations or grouping of major congenital malformation types were observed. in the naaed pregnancy registry, when topiramate-exposed infants with only oral clefts were excluded, the prevalence of major congenital malformations (4.1%) was higher than that in infants exposed to a reference aed (1.8%) or in infants with mothers without epilepsy and without exposure to aeds (1.1%). the prevalence of oral clefts among topiramate-exposed infants (1.4%) was higher than the prevalence in infants exposed to a reference aed (0.3%) or the prevalence in infants with mothers without epilepsy and without exposure to aeds (0.11%). it was also higher than the background prevalence in the united states (0.17%) as estimated by the centers for disease control and prevention (cdc). the relative risk of oral clefts in topiramate-exposed pregnancies in the naaed pregnancy registry was 12.5 (95% confidence interval=[ci] 5.9 to 26.37) as compared to the risk in a background population of untreated women. the uk epilepsy and pregnancy register reported a prevalence of oral clefts among infants exposed to topiramate monotherapy (3.2%) that was 16 times higher than the background rate in the uk (0.2%). data from the naaed pregnancy registry and a population-based birth registry cohort indicate that exposure to topiramate in utero is associated with an increased risk of sga newborns (birth weight <10th percentile). in the naaed pregnancy registry, 19.7% of topiramate-exposed newborns were sga compared to 7.9% of newborns exposed to a reference aed, and 5.4% of newborns of mothers without epilepsy and without aed exposure. in the medical birth registry of norway (mbrn), a population-based pregnancy registry, 25% of newborns in the topiramate monotherapy exposure group were sga compared to 9% in the comparison group who were unexposed to aeds. the long-term consequences of the sga findings are not known. animal data when topiramate (0, 20, 100, or 500 mg/kg/day) was administered orally to pregnant mice during the period of organogenesis, the incidence of fetal malformations (primarily craniofacial defects) were increased at all doses. fetal body weights and skeletal ossification were reduced at the highest dose tested in conjunction with decreased maternal body weight gain. a no-effect dose for embryofetal developmental toxicity in mice was not identified. the lowest dose tested, which was associated with an increased incidence of malformations, is less than the maximum recommended human dose (mrhd) for epilepsy (400 mg/day) or migraine (100 mg/day) on a body surface area (mg/m2 ) basis. in pregnant rats administered topiramate (0, 20, 100, and 500 mg/kg/day or 0, 0.2, 2.5, 30, and 400 mg/kg/day) orally during the period of organogenesis, the frequency of limb malformations (ectrodactyly, micromelia, and amelia) was increased in fetuses at 400 and 500 mg/kg/day. embryotoxicity (reduced fetal body weights, increased incidences of structural variations) was observed at doses as low as 20 mg/kg/day. clinical signs of maternal toxicity were seen at 400 mg/kg/day and above, and maternal body weight gain was reduced at doses of 100 mg/kg/day or greater. the no-effect dose (2.5 mg/kg/day) for embryofetal developmental toxicity in rats is less than the mrhd for epilepsy or migraine on a mg/m2 basis. in pregnant rabbits administered topiramate (0, 20, 60, and 180 mg/kg/day or 0, 10, 35, and 120 mg/kg/day) orally during organogenesis, embryofetal mortality was increased at 35 mg/kg/day and an increased incidence of fetal malformations (primarily rib and vertebral malformations) was observed at 120 mg/kg/day. evidence of maternal toxicity (decreased body weight gain, clinical signs, and/or mortality) was seen at 35 mg/kg/day and above. the no-effect dose (20 mg/kg/day) for embryofetal developmental toxicity in rabbits is equivalent to the mrhd for epilepsy and approximately 4 times the mrhd for migraine on a mg/m2 basis. when topiramate (0, 0.2, 4, 20, and 100 mg/kg/day or 0, 2, 20, and 200 mg/kg/day) was administered orally to female rats during the latter part of gestation and throughout lactation, offspring exhibited decreased viability and delayed physical development at 200 mg/kg/day and reductions in pre- and/or postweaning body weight gain at 2 mg/kg/day and above. maternal toxicity (decreased body weight gain, clinical signs) was evident at 100 mg/kg/day or greater. in a rat embryofetal development study which included postnatal assessment of offspring, oral administration of topiramate (0, 0.2, 2.5, 30, and 400 mg/kg/day) to pregnant animals during the period of organogenesis resulted in delayed physical development in offspring at 400 mg/kg/day and persistent reductions in body weight gain in offspring at 30 mg/kg/day and higher. the no-effect dose (0.2 mg/kg/day) for pre- and postnatal developmental toxicity in rats is less than the mrhd for epilepsy or migraine on a mg/m2 basis. risk summary topiramate is excreted in human milk [see data] . the effects of topiramate on milk production are unknown. diarrhea and somnolence have been reported in breastfed infants whose mothers receive topiramate treatment. the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for topiramate extended-release and any potential adverse effects on the breastfed infant from topiramate extended-release or from the underlying maternal condition. data human data limited data from 5 women with epilepsy treated with topiramate during lactation showed drug levels in milk similar to those in maternal plasma. contraception women of childbearing potential who are not planning a pregnancy should use effective contraception because of the risk of major congenital malformations, including oral clefts, and the risk of infants being sga [see drug interactions (7.4) and use in specific populations (8.1)] . adjunctive treatment for epilepsy pediatric patients 2 years of age and older the safety and effectiveness of topiramate extended-release as adjunctive therapy for the treatment of partial-onset seizures, primary generalized tonic-clonic seizures, or seizures associated with lennox-gastaut syndrome have been established in pediatric patients 2 years of age and older and is based on controlled trials with immediate-release topiramate [see adverse reactions (6.1) and clinical studies (14.3, 14.4)] . the adverse reactions (both common and serious) in pediatric patients are similar to those seen in adults [see warnings and precautions (5) and adverse reactions (6)] . these include, but are not limited to: - oligohydrosis and hyperthermia [see warnings and precautions (5.3)] - dose-related increased incidence of metabolic acidosis [see warnings and precautions (5.4)] - dose-related increased incidence of hyperammonemia [see warnings and precautions (5.12)] pediatric patients below the age of 2 years the following pediatric use information is based on studies conducted with immediate-release topiramate. safety and effectiveness in patients below the age of 2 years have not been established for the adjunctive therapy treatment of partial-onset seizures, primary generalized tonic-clonic seizures, or seizures associated with lennox-gastaut syndrome. in a single randomized, double-blind, placebo-controlled investigational trial, the efficacy, safety, and tolerability of immediate-release topiramate oral liquid and sprinkle formulations as an adjunct to concurrent antiepileptic drug therapy in pediatric patients 1 to 24 months of age with refractory partial-onset seizures were assessed. after 20 days of double-blind treatment, immediate-release topiramate (at fixed doses of 5, 15, and 25 mg/kg/day) did not demonstrate efficacy compared with placebo in controlling seizures. in general, the adverse reaction profile for immediate-release topiramate in this population was similar to that of older pediatric patients, although results from the above controlled study and an open-label, long-term extension study in these pediatric patients 1 to 24 months old suggested some adverse reactions/toxicities not previously observed in older pediatric patients and adults; i.e., growth/length retardation, certain clinical laboratory abnormalities, and other adverse reactions/toxicities that occurred with a greater frequency and/or greater severity than had been recognized previously from studies in older pediatric patients or adults for various indications. these very young pediatric patients appeared to experience an increased risk for infections (any topiramate dose 12%, placebo 0%) and of respiratory disorders (any topiramate dose 40%, placebo 16%). the following adverse reactions were observed in at least 3% of patients on immediate-release topiramate and were 3% to 7% more frequent than in patients on placebo: viral infection, bronchitis, pharyngitis, rhinitis, otitis media, upper respiratory infection, cough, and bronchospasm. a generally similar profile was observed in older pediatric patients [see adverse reactions (6.1)] . immediate-release topiramate resulted in an increased incidence of patients with increased creatinine (any topiramate dose 5%, placebo 0%), bun (any topiramate dose 3%, placebo 0%), and protein (any topiramate dose 34%, placebo 6%), and an increased incidence of decreased potassium (any topiramate dose 7%, placebo 0%). this increased frequency of abnormal values was not dose-related. creatinine was the only analyte showing a noteworthy increased incidence (topiramate 25 mg/kg/day 5%, placebo 0%) of a markedly abnormal increase [see adverse reactions (6.1)] . the significance of these findings is uncertain. immediate-release topiramate treatment also produced a dose-related increase in the percentage of patients who had a shift from normal at baseline to high/increased (above the normal reference range) in total eosinophil count at the end of treatment. the incidence of these abnormal shifts was 6% for placebo, 10% for 5 mg/kg/day, 9% for 15 mg/kg/day, 14% for 25 mg/kg/day, and 11% for any topiramate dose [see adverse reactions (6.1)] . there was a mean dose-related increase in alkaline phosphatase. the significance of these findings is uncertain. topiramate produced a dose-related increased incidence of hyperammonemia [see warnings and precautions (5.12)] . treatment with immediate-release topiramate for up to 1 year was associated with reductions in z scores for length, weight, and head circumference [see warnings and precautions (5.4), adverse reactions (6.1)] . in open-label, uncontrolled experience, increasing impairment of adaptive behavior was documented in behavioral testing over time in this population. there was a suggestion that this effect was dose-related. however, because of the absence of an appropriate control group, it is not known if this decrement in function was treatment related or reflects the patient's underlying disease (e.g., patients who received higher doses may have more severe underlying disease) [see warnings and precautions (5.6)] . in this open-label, uncontrolled study, the mortality was 37 deaths/1,000 patient years. it is not possible to know whether this mortality rate is related to immediate-release topiramate treatment, because the background mortality rate for a similar, significantly refractory, young pediatric population (1 to 24 months) with partial epilepsy is not known. monotherapy treatment for epilepsy pediatric patients 2 years of age and older the safety and effectiveness of topiramate extended-release capsules as monotherapy for the treatment of partial-onset seizures or primary generalized tonic-clonic seizures have been established in pediatric patients aged 2 years and older and is based on controlled trials with immediate-release topiramate [see adverse reactions (6.1), clinical studies (14.1)] . a one-year, active-controlled, open-label study with blinded assessments of bone mineral density (bmd) and growth in pediatric patients 4 to 15 years of age, including 63 patients with recent or new onset of epilepsy, was conducted to assess effects of immediate-release topiramate (n=28, 6 to 15 years of age) versus levetiracetam (n=35, 4 to 15 years of age) monotherapy on bone mineralization and on height and weight, which reflect growth. effects on bone mineralization were evaluated via dual-energy x-ray absorptiometry and blood markers. table 11 summarizes effects of immediate-release topiramate at 12 months for key safety outcomes including bmd, height, height velocity, and weight. all least square mean values for immediate-release topiramate and the comparator were positive. therefore, the least square mean treatment differences shown reflect a topiramate induced attenuation of the key safety outcomes. statistically significant effects were observed for decreases in bmd (and bone mineral content) in lumbar spine and total body less head and in weight. subgroup analyses according to age demonstrated similar negative effects for all key safety outcomes (i.e., bmd, height, weight). metabolic acidosis (serum bicarbonate < 20 meq/l) was observed in all immediate-release topiramate-treated patients at some time in the study [see warnings and precautions (5.4)] . over the whole study, 76% more immediate-release topiramate-treated patients experienced persistent metabolic acidosis (i.e., 2 consecutive visits with or final serum bicarbonate < 20 meq/l) compared to levetiracetam-treated patients. over the whole study, 35% more immediate-release topiramate-treated patients experienced a markedly abnormally low serum bicarbonate (i.e., absolute value < 17 meq/l and ≥ 5 meq/l decrease from pre-treatment), indicating the frequency of more severe metabolic acidosis, compared to levetiracetam-treated patients. the decrease in bmd at 12 months was correlated with decreased serum bicarbonate, suggesting that metabolic acidosis was at least a partial factor contributing to this adverse effect on bmd. immediate-release topiramate-treated patients exhibited an increased risk for developing an increased serum creatinine and an increased serum glucose above the normal reference range compared to control patients. pediatric patients below the age of 2 years safety and effectiveness in patients below the age of 2 years have not been established for the monotherapy treatment of epilepsy. preventive treatment of migraine pediatric patients 12 to 17 years of age safety and effectiveness of topiramate for the preventive treatment of migraine was studied in 5 double-blind, randomized, placebo-controlled, parallel-group trials in a total of 219 pediatric patients, at doses of 50 to 200 mg/day, or 2 to 3 mg/kg/day. these comprised a fixed dose study in 103 pediatric patients 12 to 17 years of age [see clinical studies (14.5)] , a flexible dose (2 to 3 mg/kg/day), placebo-controlled study in 157 pediatric patients 6 to 16 years of age (including 67 pediatric patients 12 to 16 years of age), and a total of 49 pediatric patients 12 to 17 years of age in 3 studies for the preventive treatment of migraine primarily in adults. open-label extension phases of 3 studies enabled evaluation of long-term safety for up to 6 months after the end of the double-blind phase. efficacy of topiramate for the preventive treatment of migraine in pediatric patients 12 to 17 years of age is demonstrated for a 100 mg daily dose in study 13 [see clinical studies (14.5)] . efficacy of topiramate (2 to 3 mg/kg/day) for the preventive treatment of migraine was not demonstrated in a placebo-controlled trial of 157 pediatric patients (6 to 16 years of age) that included treatment of 67 pediatric patients (12 to 16 years of age) for 20 weeks. in the pediatric trials (12 to 17 years of age) in which patients were randomized to placebo or a fixed daily dose of immediate-release topiramate, the most common adverse reactions with immediate-release topiramate that were seen at an incidence higher (≥ 5%) than in the placebo group were: paresthesia, upper respiratory tract infection, anorexia, and abdominal pain [see adverse reactions (6.1)] . the most common cognitive adverse reaction in pooled double-blind studies in pediatric patients 12 to 17 years of age was difficulty with concentration/attention [see warnings and precautions (5.6)] . markedly abnormally low serum bicarbonate values indicative of metabolic acidosis were reported in topiramate-treated pediatric migraine patients [see warnings and precautions (5.4)] . in topiramate-treated pediatric patients (12 to 17 years of age) compared to placebo-treated patients, abnormally increased results were more frequent for creatinine, bun, uric acid, chloride, ammonia, total protein, and platelets. abnormally decreased results were observed with topiramate vs placebo treatment for phosphorus and bicarbonate [see warnings and precautions (5.4) and adverse reactions (6.1)] . notable changes (increases and decreases) from baseline in systolic blood pressure, diastolic blood pressure, and pulse were observed occurred more commonly in pediatric patients treated with topiramate compared to pediatric patients treated with placebo [see clinical pharmacology (12.2)] . pediatric patients below the age of 12 years safety and effectiveness in pediatric patients below the age of 12 years have not been established for the preventive treatment of migraine. in a double-blind study in 90 pediatric patients 6 to 11 years of age (including 59 topiramate-treated and 31 placebo patients), the adverse reaction profile was generally similar to that seen in pooled double-blind studies of pediatric patients 12 to 17 years of age. the most common adverse reactions that occurred in immediate-release topiramate-treated pediatric patients 6 to 11 years of age, and at least twice as frequently than placebo, were gastroenteritis (12% topiramate, 6% placebo), sinusitis (10% topiramate, 3% placebo), weight loss (8% topiramate, 3% placebo) and paresthesia (7% topiramate, 0% placebo). difficulty with concentration/attention occurred in 3 topiramate-treated patients (5%) and 0 placebo-treated patients. the risk for cognitive adverse reaction was greater in younger patients (6 to 11 years of age) than in older patients (12 to 17 years of age) [see warnings and precautions (5.6)] . juvenile animal studies when topiramate (0, 30, 90 or 300 mg/kg/day) was administered orally to rats during the juvenile period of development (postnatal days 12 to 50), bone growth plate thickness was reduced in males at the highest dose, which is approximately 5 to 8 times the maximum recommended pediatric dose (9 mg/kg/day) on a body surface area (mg/m2 ) basis. clinical studies of immediate-release topiramate did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently than younger subjects. dosage adjustment may be necessary for elderly with creatinine clearance less than 70 ml/min/1.73 m2 . estimate gfr should be measured prior to dosing [see dosage and administration (2.3) and clinical pharmacology (12.3)] . the clearance of topiramate is reduced in patients with moderate (creatinine clearance 30 to 69 ml/min/1.73 m2 ) and severe (creatinine clearance less than 30 ml/min/1.73 m2 ) renal impairment. a dosage adjustment is recommended in patients with moderate or severe renal impairment [see dosage and administration (2.4) and clinical pharmacology (12.3)] . topiramate is cleared by hemodialysis at a rate that is 4 to 6 times greater than in a normal individual. a dosage adjustment may be required [see dosage and administration (2.5) and clinical pharmacology (12.3)] .
