tizanidine hydrochloride capsule

zydus pharmaceuticals (usa) inc. - tizanidine hydrochloride (unii: b53e3nmy5c) (tizanidine - unii:6ai06c00gw) - tizanidine 2 mg - tizanidine hydrochloride is a central alpha-2-adrenergic agonist indicated for the management of spasticity. because of the short duration of therapeutic effect, treatment with tizanidine hydrochloride capsules should be reserved for those daily activities and times when relief of spasticity is most important [see dosage and administration (2.1)] . tizanidine hydrochloride capsules are contraindicated in patients taking potent inhibitors of cyp1a2, such as fluvoxamine or ciprofloxacin [see drug interactions (7.1, 7.2)]. risk summary there are no adequate data on the developmental risk associated with use of tizanidine in pregnant women. in animal studies, administration of tizanidine during pregnancy resulted in developmental toxicity (embryofetal and postnatal offspring mortality and growth deficits) at doses less than those used clinically, which were not associated with maternal toxicity (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% to 4% and 15% to 20%, respectively. the background risk of major birth defects and miscarriage for the indicated population is unknown. data animal data oral administration of tizanidine (0.3 to 100 mg/kg/day) to pregnant rats during the period of organogenesis resulted in embryofetal and postnatal offspring mortality and reductions in body weight at doses of 30 mg/kg/day and above. maternal toxicity was observed at the highest dose tested. the no-effect dose for embryofetal developmental toxicity in rats (3 mg/kg/day) is similar to the maximum recommended human dose (mrhd) of 36 mg/day on a body surface area (mg/m2 ) basis. oral administration of tizanidine (1 to 100 mg/kg/day) to pregnant rabbits during the period of organogenesis resulted in embryofetal and postnatal offspring mortality at all doses. maternal toxicity was observed at the highest dose tested. oral administration of tizanidine (10 and 30 mg/kg/day) during the perinatal period of pregnancy (2 to 6 days prior to delivery) resulted in increased postnatal offspring mortality at both doses. a no-effect dose for embryofetal developmental toxicity in rabbit was not identified. the lowest dose tested (1 mg/kg/day) is less than the mrhd on a mg/m2 basis. in a pre- and postnatal development study in rats, oral administration of tizanidine (3 to 30 mg/kg/day) resulted in increased postnatal offspring mortality. a no-effect dose for pre- and postnatal developmental toxicity was not identified. the lowest dose tested (3 mg/kg/day) is similar to the mrhd on a mg/m2 basis, respectively. risk summary there are no data on the presence of tizanidine in human milk, the effects on the breastfed infant, or the effects on human milk production. animal studies have reported the presence of tizanidine in the milk of lactating animals. the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for tizanidine and any potential adverse effects on the breastfed infant from tizanidine or from the underlying maternal condition. there are no adequate and well-controlled studies in humans on the effect of tizanidine on female or male reproductive potential. oral administration of tizanidine to male and female rats resulted in adverse effects on fertility [see nonclinical toxicology (13.1)]. safety and effectiveness in pediatric patients have not been established. tizanidine 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. clinical studies of tizanidine did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently than younger subjects. cross-study comparison of pharmacokinetic data following single dose administration of 6 mg tizanidine showed that younger subjects cleared the drug four times faster than the elderly subjects. in elderly patients with renal insufficiency (creatinine clearance <25 ml/min), tizanidine clearance is reduced by more than 50% compared to healthy elderly subjects; this would be expected to lead to a longer duration of clinical effect. during titration, the individual doses should be reduced. if higher doses are required, individual doses rather than dosing frequency should be increased. monitor elderly patients because they may have an increased risk for adverse reactions associated with tizanidine. tizanidine 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. in patients with renal insufficiency (creatinine clearance < 25 ml/min) clearance was reduced by more than 50%. in these patients, individual doses should be reduced during titration. if higher doses are required, individual doses rather than dosing frequency should be increased. these patients should be monitored closely for the onset or increase in severity of tizanidine common adverse events (dry mouth, somnolence, asthenia and dizziness) as indicators of potential overdosage [see dosage and administration (2.2) , warnings and precautions (5.7)  and  clinical pharmacology (12.3)]. the influence of hepatic impairment on the pharmacokinetics of tizanidine has not been evaluated. because tizanidine is extensively metabolized in the liver, hepatic impairment would be expected to have significant effects on pharmacokinetics of tizanidine [see dosing and administration (2.3) , warnings and precautions (5.2) , and  clinical pharmacology (12.3)]. abuse potential was not evaluated in human studies. rats were able to distinguish tizanidine from saline in a standard discrimination paradigm, after training, but failed to generalize the effects of morphine, cocaine, diazepam, or phenobarbital to tizanidine. tizanidine is closely related to clonidine, which is often abused in combination with narcotics and is known to cause symptoms of rebound upon abrupt withdrawal. three cases of rebound symptoms on sudden withdrawal of tizanidine have been reported. the case reports suggest that these patients were also misusing narcotics. withdrawal symptoms included hypertension, tachycardia, hypertonia, tremor, and anxiety. withdrawal symptoms are more likely to occur in cases where high doses are used, especially for prolonged periods, or with concomitant use of narcotics. if therapy needs to be discontinued, the dose should be decreased slowly to minimize the risk of withdrawal symptoms [see dosage and administration (2.2)]. monkeys were shown to self-administer tizanidine in a dose-dependent manner, and abrupt cessation of tizanidine produced transient signs of withdrawal at doses > 35 times the maximum recommended human dose on a mg/m2 basis. these transient withdrawal signs (increased locomotion, body twitching, and aversive behavior toward the observer) were not reversed by naloxone administration.

LEVETIRACETAM tablet, film coated United States - English - NLM (National Library of Medicine)

levetiracetam tablet, film coated

lupin pharmaceuticals, inc. - levetiracetam (unii: 44yrr34555) (levetiracetam - unii:44yrr34555) - levetiracetam 250 mg - levetiracetam tablets usp are indicated for treatment of partial-onset seizures in patients 1 month of age and older. levetiracetam tablets usp are indicated as adjunctive therapy for the treatment of myoclonic seizures in patients 12 years of age and older with juvenile myoclonic epilepsy. levetiracetam tablets usp are 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 is contraindicated in patients with a hypersensitivity to levetiracetam. reactions have included anaphylaxis and angioedema [see warnings and precautions (5.4)] . pregnancy exposure registry 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 (5.10)]. 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 incidences of fetal skeletal abnormalities at variations at the mid and high dose and decreased fetal weights and increased incidence of fetal malformations at the high dose, which  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). the effect of levetiracetam on labor and delivery in humans is unknown. 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 studies (14.1)] . the dosing recommendation in these pediatric patients varies according to age group and is weight-based [see pharmacology (12.3) and clinical studies (14.1)] . 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 to 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 to 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 day 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)] .

forteo- teriparatide injection, solution

eli lilly and company - teriparatide (unii: 10t9csu89i) (teriparatide - unii:10t9csu89i) - teriparatide 250 ug in 1 ml - forteo is indicated: - for the treatment of postmenopausal women with osteoporosis at high risk for fracture (defined herein as having a history of osteoporotic fracture or multiple risk factors for fracture) or who have failed or are intolerant to other available osteoporosis therapy. in postmenopausal women with osteoporosis, forteo reduces the risk of vertebral and nonvertebral fractures. - to increase bone mass in men with primary or hypogonadal osteoporosis at high risk for fracture or who have failed or are intolerant to other available osteoporosis therapy. - for the treatment of men and women with osteoporosis associated with sustained systemic glucocorticoid therapy (daily dosage equivalent to 5 mg or greater of prednisone) at high risk for fracture or who have failed or are intolerant to other available osteoporosis therapy. forteo is contraindicated in patients with hypersensitivity to teriparatide or to any of its excipients. hypersensitivity reactions have included angioedema and anaphylaxis [see adverse reactions (6.3)] . risk summary there are no available data on forteo use in pregnant women to evaluate for drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. consider discontinuing forteo when pregnancy is recognized. in animal reproduction studies, teriparatide increased skeletal deviations and variations in mouse offspring at subcutaneous doses equivalent to more than 60 times the recommended 20 mcg human daily dose (based on body surface area, mcg/m2 ), and produced mild growth retardation and reduced motor activity in rat offspring at subcutaneous doses equivalent to more than 120 times the human dose (see data ). the background risk of major birth defects and miscarriage for the indicated population is unknown. the background risk in the us general population of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies. data animal data in animal reproduction studies, pregnant mice received teriparatide during organogenesis at subcutaneous doses equivalent to 8 to 267 times the human dose (based on body surface area, mcg/m2 ). at subcutaneous doses ≥60 times the human dose, the fetuses showed an increased incidence of skeletal deviations or variations (interrupted rib, extra vertebra or rib). when pregnant rats received teriparatide during organogenesis at subcutaneous doses 16 to 540 times the human dose, the fetuses showed no abnormal findings. in a perinatal/postnatal study in pregnant rats dosed subcutaneously from organogenesis through lactation, mild growth retardation was observed in female offspring at doses ≥120 times the human dose. mild growth retardation in male offspring and reduced motor activity in both male and female offspring were observed at maternal doses of 540 times the human dose. there were no developmental or reproductive effects in mice or rats at doses 8 or 16 times the human dose, respectively. risk summary it is not known whether teriparatide is excreted in human milk, affects human milk production, or has effects on the breastfed infant. avoid forteo use in women who are breastfeeding. the safety and effectiveness of forteo have not been established in pediatric patients. pediatric patients are at higher baseline risk of osteosarcoma because of open epiphyses [see warnings and precautions (5.1)] . of the patients who received forteo in the osteoporosis trial of 1637 postmenopausal women, 75% were 65 years of age and older and 23% were 75 years of age and older. of the patients who received forteo in the trial of 437 men with primary or hypogonadal osteoporosis, 39% were 65 years of age and over and 13% were 75 years of age and over. of the 214 patients who received forteo in the glucocorticoid induced osteoporosis trial, 28% were 65 years of age and older and 9% were 75 years of age and older. no overall differences in safety or effectiveness of forteo have been observed between patients 65 years of age and older and younger adult patients. no studies have been performed in patients with hepatic impairment [see clinical pharmacology (12.3)] . in 5 patients with severe renal impairment (crcl<30 ml/minute), the auc and t1/2 of teriparatide were increased by 73% and 77%, respectively. maximum serum concentration of teriparatide was not increased. it is unknown whether forteo alters the underlying metabolic bone disease seen in chronic renal impairment [see clinical pharmacology (12.3)] . forteo® (for-tay-o) teriparatide injection user manual important: first read the medication

DIVALPROEX SODIUM tablet, delayed release United States - English - NLM (National Library of Medicine)

divalproex sodium tablet, delayed release

remedyrepack inc. - divalproex sodium (unii: 644vl95ao6) (valproic acid - unii:614oi1z5wi) - valproic acid 125 mg - divalproex sodium is a valproate and is indicated for the treatment of the manic episodes associated with bipolar disorder. a manic episode is a distinct period of abnormally and persistently elevated, expansive, or irritable mood. typical symptoms of mania include pressure of speech, motor hyperactivity, reduced need for sleep, flight of ideas, grandiosity, poor judgment, aggressiveness, and possible hostility. the efficacy of divalproex sodium delayed-release tablets  was established in 3-week trials with patients meeting dsm-iii-r criteria for bipolar disorder who were hospitalized for acute mania [see clinical studies ( 14.1)] . the safety and effectiveness of divalproex sodium delayed-release tablets  for long-term use in mania, i.e., more than 3 weeks, has not been demonstrated in controlled clinical trials. therefore, healthcare providers who elect to use divalproex sodium delayed-release tablets for extended periods should continually reevaluate the long-term usefulness of the drug for the  individual patient. divalproex sodium delayed-release tablets are indicated as monotherapy and adjunctive therapy in the treatment of patients with complex partial seizures that occur either in isolation or in association with other types of seizures. divalproex sodium delayed-release tablets are also indicated for use as sole and adjunctive therapy in the treatment of simple and complex absence seizures, and adjunctively in patients with multiple seizure types that include absence seizures. simple absence is defined as very brief clouding of the sensorium or loss of consciousness accompanied by certain generalized epileptic discharges without other detectable clinical signs. complex absence is the term used when other signs are also present. divalproex sodium delayed-release tablets are indicated for prophylaxis of migraine headaches. there is no evidence that divalproex sodium delayed-release tablets are useful in the acute treatment of migraine headaches. because of the risk to the fetus of decreased iq, neurodevelopmental disorders, neural tube defects, and other major congenital malformations, which may occur very early in pregnancy, valproate should not be used to treat women with epilepsy or bipolar disorder who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable. valproate should not be administered to a woman of childbearing potential unless other medications have failed to provide adequate symptom control or are otherwise unacceptable [see warnings and precautions (5.2, 5.3, 5.4), use in specific populations (8.1), and patient counseling information (17)]. for prophylaxis of migraine headaches, divalproex sodium is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see contraindications (4)]. - divalproex sodium should not be administered to patients with hepatic disease or significant hepatic dysfunction [see warnings and precautions (5.1)]. - divalproex sodium is contraindicated in patients known to have mitochondrial disorders caused by mutations in mitochondrial dna polymerase γ (polg; e.g., alpers-huttenlocher syndrome) and children under two years of age who are suspected of having a polg-related disorder [see warnings and precautions (5.1)]. - divalproex sodium is contraindicated in patients with known hypersensitivity to the drug [see warnings and precautions (5.12)]. - divalproex sodium is contraindicated in patients with known urea cycle disorders [see warnings and precautions (5.6)]. - for use in prophylaxis of migraine headaches: divalproex sodium is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see warnings and precautions (5.2, 5.3, 5.4) and use in specific populations (8.1)]. pregnancy exposure registry there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (aeds), including divalproex sodium delayed-release tablets, during pregnancy. encourage women who are taking divalproex sodium delayed-release tablets during pregnancy to enroll in the north american antiepileptic drug (naaed) pregnancy registry by calling toll-free 1-888-233-2334 or visiting the website, http://www.aedpregnancyregistry.org/. this must be done by the patient herself. risk summary for use in prophylaxis of migraine headaches, valproate is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see contraindications (4)] . for use in epilepsy or bipolar disorder, valproate should not be used to treat women who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable [see boxed warning and warnings and precautions (5.2, 5.3)] . women with epilepsy who become pregnant while taking valproate should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life. maternal valproate use during pregnancy for any indication increases the risk of congenital malformations, particularly neural tube defects including spina bifida, but also malformations involving other body systems (e.g., craniofacial defects including oral clefts, cardiovascular malformations, hypospadias, limb malformations). this risk is dose-dependent; however, a threshold dose below which no risk exists cannot be established. in utero exposure to valproate may also result in hearing impairment or hearing loss. valproate polytherapy with other aeds has been associated with an increased frequency of congenital malformations compared with aed monotherapy. the risk of major structural abnormalities is greatest during the first trimester; however, other serious developmental effects can occur with valproate use throughout pregnancy. the rate of congenital malformations among babies born to epileptic mothers who used valproate during pregnancy has been shown to be about four times higher than the rate among babies born to epileptic mothers who used other anti-seizure monotherapies [see warnings and precautions (5.2) and data (human)] . epidemiological studies have indicated that children exposed to valproate in utero have lower iq scores and a higher risk of neurodevelopmental disorders compared to children exposed to either another aed in utero or to no aeds in utero [see warnings and precautions (5.3) and data (human)] . an observational study has suggested that exposure to valproate products during pregnancy increases the risk of autism spectrum disorders [see data (human)] . in animal studies, valproate administration during pregnancy resulted in fetal structural malformations similar to those seen in humans and neurobehavioral deficits in the offspring at clinically relevant doses [see data (animal)] . there have been reports of hypoglycemia in neonates and fatal cases of hepatic failure in infants following maternal use of valproate during pregnancy. pregnant women taking valproate may develop hepatic failure or clotting abnormalities including thrombocytopenia, hypofibrinogenemia, and/or decrease in other coagulation factors, which may result in hemorrhagic complications in the neonate including death [see warnings and precautions (5.1, 5.8)] . available prenatal diagnostic testing to detect neural tube and other defects should be offered to pregnant women using valproate. evidence suggests that folic acid supplementation prior to conception and during the first trimester of pregnancy decreases the risk for congenital neural tube defects in the general population. it is not known whether the risk of neural tube defects or decreased iq in the offspring of women receiving valproate is reduced by folic acid supplementation. dietary folic acid supplementation both prior to conception and during pregnancy should be routinely recommended for patients using valproate [see warnings and precautions (5.2, 5.4)]. 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 disease-associated maternal and/or embryo/fetal risk to prevent major seizures, women with epilepsy should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life. even minor seizures may pose some hazard to the developing embryo or fetus [see warnings and precautions (5.4)] . however, discontinuation of the drug may be considered prior to and during pregnancy in individual cases if the seizure disorder severity and frequency do not pose a serious threat to the patient. maternal adverse reactions pregnant women taking valproate may develop clotting abnormalities including thrombocytopenia, hypofibrinogenemia, and/or decrease in other coagulation factors, which may result in hemorrhagic complications in the neonate including death [see warnings and precautions (5.8)] . if valproate is used in pregnancy, the clotting parameters should be monitored carefully in the mother. if abnormal in the mother, then these parameters should also be monitored in the neonate. patients taking valproate may develop hepatic failure [see boxed warning and warnings and precautions (5.1)] . fatal cases of hepatic failure in infants exposed to valproate in utero have also been reported following maternal use of valproate during pregnancy. hypoglycemia has been reported in neonates whose mothers have taken valproate during pregnancy. data human neural tube defects and other structural abnormalities there is an extensive body of evidence demonstrating that exposure to valproate in utero increases the risk of neural tube defects and other structural abnormalities. based on published data from the cdc’s national birth defects prevention network, the risk of spina bifida in the general population is about 0.06 to 0.07% (6 to 7 in 10,000 births) compared to the risk following in utero valproate exposure estimated to be approximately 1 to 2% (100 to 200 in 10,000 births). the naaed pregnancy registry has reported a major malformation rate of 9 to 11% in the offspring of women exposed to an average of 1,000 mg/day of valproate monotherapy during pregnancy. these data show an up to a five-fold increased risk for any major malformation following valproate exposure in utero compared to the risk following exposure in utero to other aeds taken as monotherapy. the major congenital malformations included cases of neural tube defects, cardiovascular malformations, craniofacial defects (e.g., oral clefts, craniosynostosis), hypospadias, limb malformations (e.g., clubfoot, polydactyly), and other malformations of varying severity involving other body systems [see warnings and precautions (5.2)]. effect on iq and neurodevelopmental effects published epidemiological studies have indicated that children exposed to valproate in utero have lower iq scores than children exposed to either another aed in utero or to no aeds in utero . the largest of these studies 1 is a prospective cohort study conducted in the united states and united kingdom that found that children with prenatal exposure to valproate (n=62) had lower iq scores at age 6 (97 [95% c.i. 94 to 101]) than children with prenatal exposure to the other anti-epileptic drug monotherapy treatments evaluated: lamotrigine (108 [95% c.i. 105 to 110]), carbamazepine (105 [95% c.i. 102 to 108]) and phenytoin (108 [95% c.i. 104 to 112]). it is not known when during pregnancy cognitive effects in valproate-exposed children occur. because the women in this study were exposed to aeds throughout pregnancy, whether the risk for decreased iq was related to a particular time period during pregnancy could not be assessed [ see warnings and precautions (5.3)] . although the available studies have methodological limitations, the weight of the evidence supports a causal association between valproate exposure in utero and subsequent adverse effects on neurodevelopment, including increases in autism spectrum disorders and attention deficit/hyperactivity disorder (adhd). an observational study has suggested that exposure to valproate products during pregnancy increases the risk of autism spectrum disorders. in this study, children born to mothers who had used valproate products during pregnancy had 2.9 times the risk (95% confidence interval [ci]: 1.7-4.9) of developing autism spectrum disorders compared to children born to mothers not exposed to valproate products during pregnancy. the absolute risks for autism spectrum disorders were 4.4% (95% ci: 2.6%-7.5%) in valproate-exposed children and 1.5% (95% ci: 1.5%-1.6%) in children not exposed to valproate products. another observational study found that children who were exposed to valproate in utero had an increased risk of adhd (adjusted hr 1.48; 95% ci, 1.09-2.00) compared with the unexposed children. because these studies were observational in nature, conclusions regarding a causal association between in utero valproate exposure and an increased risk of autism spectrum disorder and adhd cannot be considered definitive. other there are published case reports of fatal hepatic failure in offspring of women who used valproate during pregnancy. animal in developmental toxicity studies conducted in mice, rats, rabbits, and monkeys, increased rates of fetal structural abnormalities, intrauterine growth retardation, and embryo-fetal death occurred following administration of valproate to pregnant animals during organogenesis at clinically relevant doses (calculated on a body surface area [mg/m 2 ] basis). valproate induced malformations of multiple organ systems, including skeletal, cardiac, and urogenital defects. in mice, in addition to other malformations, fetal neural tube defects have been reported following valproate administration during critical periods of organogenesis, and the teratogenic response correlated with peak maternal drug levels. behavioral abnormalities (including cognitive, locomotor, and social interaction deficits) and brain histopathological changes have also been reported in mice and rat offspring exposed prenatally to clinically relevant doses of valproate. risk summary valproate is excreted in human milk. data in the published literature describe the presence of valproate in human milk (range: 0.4 mcg/ml to 3.9 mcg/ml), corresponding to 1% to 10% of maternal serum levels. valproate serum concentrations collected from breastfed infants aged 3 days postnatal to 12 weeks following delivery ranged from 0.7 mcg/ml to 4 mcg/ml, which were 1% to 6% of maternal serum valproate levels. a published study in children up to six years of age did not report adverse developmental or cognitive effects following exposure to valproate via breast milk [see data (human)].          there are no data to assess the effects of divalproex sodium delayed-release tablets on milk production or excretion. clinical considerations the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for divalproex sodium and any potential adverse effects on the breastfed infant from divalproex sodium or from the underlying maternal condition. monitor the breastfed infant for signs of liver damage including jaundice and unusual bruising or bleeding. there have been reports of hepatic failure and clotting abnormalities in offspring of women who used valproate during pregnancy [see use in specific populations (8.1)] . data human in a published study, breast milk and maternal blood samples were obtained from 11 epilepsy patients taking valproate at doses ranging from 300 mg/day to 2,400 mg/day on postnatal days 3 to 6. in 4 patients who were taking valproate only, breast milk contained an average valproate concentration of 1.8 mcg/ml (range: 1.1 mcg/ml to 2.2 mcg/ml), which corresponded to 4.8% of the maternal plasma concentration (range: 2.7% to 7.4%). across all patients (7 of whom were taking other aeds concomitantly), similar results were obtained for breast milk concentration (1.8 mcg/ml, range: 0.4 mcg/ml to 3.9 mcg/ml) and maternal plasma ratio (5.1%, range: 1.3% to 9.6%). a published study of 6 breastfeeding mother-infant pairs measured serum valproate levels during maternal treatment for bipolar disorder (750 mg/day or 1,000 mg/day). none of the mothers received valproate during pregnancy, and infants were aged from 4 weeks to 19 weeks at the time of evaluation. infant serum levels ranged from 0.7 mcg/ml to 1.5 mcg/ml. with maternal serum valproate levels near or within the therapeutic range, infant exposure was 0.9% to 2.3% of maternal levels. similarly, in 2 published case reports with maternal doses of 500 mg/day or 750 mg/day during breastfeeding of infants aged 3 months and 1 month, infant exposure was 1.5% and 6% that of the mother, respectively. a prospective observational multicenter study evaluated the long-term neurodevelopmental effects of aed use on children. pregnant women receiving monotherapy for epilepsy were enrolled with assessments of their children at ages 3 years and 6 years. mothers continued aed therapy during the breastfeeding period. adjusted iqs measured at 3 years for breastfed and non-breastfed children were 93 (n=11) and 90 (n=24), respectively. at 6 years, the scores for breastfed and non-breastfed children were 106 (n=11) and 94 (n=25), respectively (p=0.04). for other cognitive domains evaluated at 6 years, no adverse cognitive effects of continued exposure to an aed (including valproate) via breast milk were observed. contraception women of childbearing potential should use effective contraception while taking valproate [see boxed warning, warnings and precautions (5.4), drug interactions (7), and use in specific populations (8.1)] . this is especially important when valproate use is considered for a condition not usually associated with permanent injury or death such as prophylaxis of migraine headaches [see contraindications (4)] . infertility there have been reports of male infertility coincident with valproate therapy [see adverse reactions (6.4)] . in animal studies, oral administration of valproate at clinically relevant doses resulted in adverse reproductive effects in males [see nonclinical toxicology (13.1)] . experience has indicated that pediatric patients under the age of two years are at a considerably increased risk of developing fatal hepatotoxicity, especially those with the aforementioned conditions [see boxed warning and warnings and precautions (5.1)] . when divalproex sodium delayed-release tablets are used in this patient group, it should be used with extreme caution and as a sole agent. the benefits of therapy should be weighed against the risks. above the age of 2 years, experience in epilepsy has indicated that the incidence of fatal hepatotoxicity decreases considerably in progressively older patient groups. younger children, especially those receiving enzyme-inducing drugs, will require larger maintenance doses to attain targeted total and unbound valproate concentrations. pediatric patients (i.e., between 3 months and 10 years) have 50% higher clearances expressed on weight (i.e., ml/min/kg) than do adults. over the age of 10 years, children have pharmacokinetic parameters that approximate those of adults. the variability in free fraction limits the clinical usefulness of monitoring total serum valproic acid concentrations. interpretation of valproic acid concentrations in children should include consideration of factors that affect hepatic metabolism and protein binding. pediatric clinical trials divalproex sodium delayed-release tablets were studied in seven pediatric clinical trials. two of the pediatric studies were double-blinded placebo-controlled trials to evaluate the efficacy of divalproex sodium extended-release tablets for the indications of mania (150 patients aged 10 to 17 years, 76 of whom were on divalproex sodium extended-release tablets) and migraine (304 patients aged 12 to 17 years, 231 of whom were on divalproex sodium extended-release tablets). efficacy was not established for either the treatment of migraine or the treatment of mania. the most common drug-related adverse reactions (reported >5% and twice the rate of placebo) reported in the controlled pediatric mania study were nausea, upper abdominal pain, somnolence, increased ammonia, gastritis and rash. the remaining five trials were long term safety studies. two six-month pediatric studies were conducted to evaluate the long-term safety of divalproex sodium extended-release tablets for the indication of mania (292 patients aged 10 to 17 years). two twelve-month pediatric studies were conducted to evaluate the long-term safety of divalproex sodium extended-release tablets for the indication of migraine (353 patients aged 12 to 17 years). one twelve-month study was conducted to evaluate the safety of divalproex sodium sprinkle capsules in the indication of partial seizures (169 patients aged 3 to 10 years). in these seven clinical trials, the safety and tolerability of divalproex sodium delayed-release tablets in pediatric patients were shown to be comparable to those in adults [see adverse reactions (6)] . juvenile animal toxicology in studies of valproate in immature animals, toxic effects not observed in adult animals included retinal dysplasia in rats treated during the neonatal period (from postnatal day 4) and nephrotoxicity in rats treated during the neonatal and juvenile (from postnatal day 14) periods. the no-effect dose for these findings was less than the maximum recommended human dose on a mg/m 2 basis. no patients above the age of 65 years were enrolled in double-blind prospective clinical trials of mania associated with bipolar illness. in a case review study of 583 patients, 72 patients (12%) were greater than 65 years of age. a higher percentage of patients above 65 years of age reported accidental injury, infection, pain, somnolence, and tremor. discontinuation of valproate was occasionally associated with the latter two events. it is not clear whether these events indicate additional risk or whether they result from preexisting medical illness and concomitant medication use among these patients. a study of elderly patients with dementia revealed drug related somnolence and discontinuation for somnolence [see warnings and precautions ( 5.14)] . the starting dose should be reduced in these patients, and dosage reductions or discontinuation should be considered in patients with excessive somnolence [see dosage and administration ( 2.4)] . there is insufficient information available to discern the safety and effectiveness of valproate for the prophylaxis of migraines in patients over 65.

topiramate tablet

remedyrepack inc. - topiramate (unii: 0h73wjj391) (topiramate - unii:0h73wjj391) - topiramate tablets are indicated as initial monotherapy for the treatment of partial-onset or primary generalized tonic-clonic seizures in patients 2 years of age and older. topiramate tablets are indicated as adjunctive therapy for the treatment of partial-onset seizures, primary generalized tonic-clonic seizures, and seizures associated with lennox-gastaut syndrome in patients 2 years of age and older. topiramate tablets 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 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 can cause fetal harm when administered to a pregnant woman. data from pregnancy registries indicate that infants exposed to topiramate in utero have an 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 in multiple animal species, topiramate produced 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 2-4% 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, 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 tablets 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 tablets 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 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 – 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 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 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 increased 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 increased incidences of fetal malformations (primarily rib and vertebral malformations) were 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) 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 tablets and any potential adverse effects on the breastfed infant from topiramate tablets 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 tablets 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 [see adverse reactions ( 6.1) and clinical studies ( 14.2)]. 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 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 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, 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 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 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)] . 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. the significance of these findings is uncertain. 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. 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 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)] . 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/1000 patient years. it is not possible to know whether this mortality rate is related to topiramate treatment, because the background mortality rate for a similar, significantly refractory, young pediatric population (1-24 months) with partial epilepsy is not known. monotherapy treatment partial-onset epilepsy in patients <2 years older the safety and effectiveness of topiramate 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 [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 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 10 summarizes effects of topiramate   at 12 months for key safety outcomes including bmd, height, height velocity, and weight. all least square mean values for 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). 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 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 ( 14.3)] , 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 ( 14.3)]. 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 topiramate, the most common adverse reactions with 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)] . 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 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)]. 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 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, 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. the no-effect dose (90 mg/kg/day) for adverse developmental effects is approximately 2 times the maximum recommended pediatric dose (9 mg/kg/day) on a body surface area (mg/m 2 ) basis. * tblh=total body less head ** whereas no patients were randomized to 2-5 year age subgroup for topiramate tablets, 5 patients (4-5 years) were randomized to the active control group. metabolic acidosis (serum bicarbonate < 20 meq/l) was observed in all topiramate tablets-treated patients at some time in the study [see warnings and precautions ( 5.4)]. over the whole study, 76% more topiramate tablets-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 topiramate tablets-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. topiramate tablets-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

developmental effects is approximately 2 times the maximum recommended pediatric dose (9 mg/kg/day) on a body surface area (mg/m 2 ) basis. in clinical trials, 3% of patients were over age 60. no age-related differences in effectiveness or adverse effects were evident. however, clinical studies of 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 age-related renal impairment (creatinine clearance rate <70 ml/min/1.73 m 2 ) resulting in reduced clearance [see dosage and administration ( 2.5), clinical pharmacology ( 12.3)] . the clearance of topiramate is reduced in patients with moderate (creatinine clearance 30 to 69 ml/min/1.73 m 2 ) and severe (creatinine clearance <30 ml/min/1.73 m 2 ) renal impairment. a dosage adjustment is recommended in patients with moderate or severe renal impairment [see dosage and administration ( 2.5),   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),   clinical pharmacology ( 12.3)].

DIVALPROEX SODIUM tablet, delayed release United States - English - NLM (National Library of Medicine)

divalproex sodium tablet, delayed release

remedyrepack inc. - divalproex sodium (unii: 644vl95ao6) (valproic acid - unii:614oi1z5wi) - divalproex sodium is a valproate and is indicated for the treatment of the manic episodes associated with bipolar disorder. a manic episode is a distinct period of abnormally and persistently elevated, expansive, or irritable mood. typical symptoms of mania include pressure of speech, motor hyperactivity, reduced need for sleep, flight of ideas, grandiosity, poor judgment, aggressiveness, and possible hostility. the efficacy of divalproex sodium delayed-release tablets  was established in 3-week trials with patients meeting dsm-iii-r criteria for bipolar disorder who were hospitalized for acute mania [see clinical studies ( 14.1)] . the safety and effectiveness of divalproex sodium delayed-release tablets  for long-term use in mania, i.e., more than 3 weeks, has not been demonstrated in controlled clinical trials. therefore, healthcare providers who elect to use divalproex sodium delayed-release tablets for extended periods should continually reevaluate the long-term usefulness of the drug for the  individual patient. divalproex sodium delayed-release tablets are indicated as monotherapy and adjunctive therapy in the treatment of patients with complex partial seizures that occur either in isolation or in association with other types of seizures. divalproex sodium delayed-release tablets are also indicated for use as sole and adjunctive therapy in the treatment of simple and complex absence seizures, and adjunctively in patients with multiple seizure types that include absence seizures. simple absence is defined as very brief clouding of the sensorium or loss of consciousness accompanied by certain generalized epileptic discharges without other detectable clinical signs. complex absence is the term used when other signs are also present. divalproex sodium delayed-release tablets are indicated for prophylaxis of migraine headaches. there is no evidence that divalproex sodium delayed-release tablets are useful in the acute treatment of migraine headaches. because of the risk to the fetus of decreased iq, neurodevelopmental disorders, neural tube defects, and other major congenital malformations, which may occur very early in pregnancy, valproate should not be used to treat women with epilepsy or bipolar disorder who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable. valproate should not be administered to a woman of childbearing potential unless other medications have failed to provide adequate symptom control or are otherwise unacceptable [see warnings and precautions (5.2, 5.3, 5.4), use in specific populations (8.1), and patient counseling information (17)]. for prophylaxis of migraine headaches, divalproex sodium is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see contraindications (4)]. - divalproex sodium should not be administered to patients with hepatic disease or significant hepatic dysfunction [see warnings and precautions (5.1)]. - divalproex sodium is contraindicated in patients known to have mitochondrial disorders caused by mutations in mitochondrial dna polymerase γ (polg; e.g., alpers-huttenlocher syndrome) and children under two years of age who are suspected of having a polg-related disorder [see warnings and precautions (5.1)]. - divalproex sodium is contraindicated in patients with known hypersensitivity to the drug [see warnings and precautions (5.12)]. - divalproex sodium is contraindicated in patients with known urea cycle disorders [see warnings and precautions (5.6)]. - for use in prophylaxis of migraine headaches: divalproex sodium is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see warnings and precautions (5.2, 5.3, 5.4) and use in specific populations (8.1)]. pregnancy exposure registry there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (aeds), including divalproex sodium delayed-release tablets, during pregnancy. encourage women who are taking divalproex sodium delayed-release tablets during pregnancy to enroll in the north american antiepileptic drug (naaed) pregnancy registry by calling toll-free 1-888-233-2334 or visiting the website, http://www.aedpregnancyregistry.org/. this must be done by the patient herself. risk summary for use in prophylaxis of migraine headaches, valproate is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see contraindications (4)] . for use in epilepsy or bipolar disorder, valproate should not be used to treat women who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable [see boxed warning and warnings and precautions (5.2, 5.3)] . women with epilepsy who become pregnant while taking valproate should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life. maternal valproate use during pregnancy for any indication increases the risk of congenital malformations, particularly neural tube defects including spina bifida, but also malformations involving other body systems (e.g., craniofacial defects including oral clefts, cardiovascular malformations, hypospadias, limb malformations). this risk is dose-dependent; however, a threshold dose below which no risk exists cannot be established. in utero exposure to valproate may also result in hearing impairment or hearing loss. valproate polytherapy with other aeds has been associated with an increased frequency of congenital malformations compared with aed monotherapy. the risk of major structural abnormalities is greatest during the first trimester; however, other serious developmental effects can occur with valproate use throughout pregnancy. the rate of congenital malformations among babies born to epileptic mothers who used valproate during pregnancy has been shown to be about four times higher than the rate among babies born to epileptic mothers who used other anti-seizure monotherapies [see warnings and precautions (5.2) and data (human)] . epidemiological studies have indicated that children exposed to valproate in utero have lower iq scores and a higher risk of neurodevelopmental disorders compared to children exposed to either another aed in utero or to no aeds in utero [see warnings and precautions (5.3) and data (human)] . an observational study has suggested that exposure to valproate products during pregnancy increases the risk of autism spectrum disorders [see data (human)] . in animal studies, valproate administration during pregnancy resulted in fetal structural malformations similar to those seen in humans and neurobehavioral deficits in the offspring at clinically relevant doses [see data (animal)] . there have been reports of hypoglycemia in neonates and fatal cases of hepatic failure in infants following maternal use of valproate during pregnancy. pregnant women taking valproate may develop hepatic failure or clotting abnormalities including thrombocytopenia, hypofibrinogenemia, and/or decrease in other coagulation factors, which may result in hemorrhagic complications in the neonate including death [see warnings and precautions (5.1, 5.8)] . available prenatal diagnostic testing to detect neural tube and other defects should be offered to pregnant women using valproate. evidence suggests that folic acid supplementation prior to conception and during the first trimester of pregnancy decreases the risk for congenital neural tube defects in the general population. it is not known whether the risk of neural tube defects or decreased iq in the offspring of women receiving valproate is reduced by folic acid supplementation. dietary folic acid supplementation both prior to conception and during pregnancy should be routinely recommended for patients using valproate [see warnings and precautions (5.2, 5.4)]. 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 disease-associated maternal and/or embryo/fetal risk to prevent major seizures, women with epilepsy should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life. even minor seizures may pose some hazard to the developing embryo or fetus [see warnings and precautions (5.4)] . however, discontinuation of the drug may be considered prior to and during pregnancy in individual cases if the seizure disorder severity and frequency do not pose a serious threat to the patient. maternal adverse reactions pregnant women taking valproate may develop clotting abnormalities including thrombocytopenia, hypofibrinogenemia, and/or decrease in other coagulation factors, which may result in hemorrhagic complications in the neonate including death [see warnings and precautions (5.8)] . if valproate is used in pregnancy, the clotting parameters should be monitored carefully in the mother. if abnormal in the mother, then these parameters should also be monitored in the neonate. patients taking valproate may develop hepatic failure [see boxed warning and warnings and precautions (5.1)] . fatal cases of hepatic failure in infants exposed to valproate in utero have also been reported following maternal use of valproate during pregnancy. hypoglycemia has been reported in neonates whose mothers have taken valproate during pregnancy. data human neural tube defects and other structural abnormalities there is an extensive body of evidence demonstrating that exposure to valproate in utero increases the risk of neural tube defects and other structural abnormalities. based on published data from the cdc’s national birth defects prevention network, the risk of spina bifida in the general population is about 0.06 to 0.07% (6 to 7 in 10,000 births) compared to the risk following in utero valproate exposure estimated to be approximately 1 to 2% (100 to 200 in 10,000 births). the naaed pregnancy registry has reported a major malformation rate of 9 to 11% in the offspring of women exposed to an average of 1,000 mg/day of valproate monotherapy during pregnancy. these data show an up to a five-fold increased risk for any major malformation following valproate exposure in utero compared to the risk following exposure in utero to other aeds taken as monotherapy. the major congenital malformations included cases of neural tube defects, cardiovascular malformations, craniofacial defects (e.g., oral clefts, craniosynostosis), hypospadias, limb malformations (e.g., clubfoot, polydactyly), and other malformations of varying severity involving other body systems [see warnings and precautions (5.2)]. effect on iq and neurodevelopmental effects published epidemiological studies have indicated that children exposed to valproate in utero have lower iq scores than children exposed to either another aed in utero or to no aeds in utero . the largest of these studies 1 is a prospective cohort study conducted in the united states and united kingdom that found that children with prenatal exposure to valproate (n=62) had lower iq scores at age 6 (97 [95% c.i. 94 to 101]) than children with prenatal exposure to the other anti-epileptic drug monotherapy treatments evaluated: lamotrigine (108 [95% c.i. 105 to 110]), carbamazepine (105 [95% c.i. 102 to 108]) and phenytoin (108 [95% c.i. 104 to 112]). it is not known when during pregnancy cognitive effects in valproate-exposed children occur. because the women in this study were exposed to aeds throughout pregnancy, whether the risk for decreased iq was related to a particular time period during pregnancy could not be assessed [ see warnings and precautions (5.3)] . although the available studies have methodological limitations, the weight of the evidence supports a causal association between valproate exposure in utero and subsequent adverse effects on neurodevelopment, including increases in autism spectrum disorders and attention deficit/hyperactivity disorder (adhd). an observational study has suggested that exposure to valproate products during pregnancy increases the risk of autism spectrum disorders. in this study, children born to mothers who had used valproate products during pregnancy had 2.9 times the risk (95% confidence interval [ci]: 1.7-4.9) of developing autism spectrum disorders compared to children born to mothers not exposed to valproate products during pregnancy. the absolute risks for autism spectrum disorders were 4.4% (95% ci: 2.6%-7.5%) in valproate-exposed children and 1.5% (95% ci: 1.5%-1.6%) in children not exposed to valproate products. another observational study found that children who were exposed to valproate in utero had an increased risk of adhd (adjusted hr 1.48; 95% ci, 1.09-2.00) compared with the unexposed children. because these studies were observational in nature, conclusions regarding a causal association between in utero valproate exposure and an increased risk of autism spectrum disorder and adhd cannot be considered definitive. other there are published case reports of fatal hepatic failure in offspring of women who used valproate during pregnancy. animal in developmental toxicity studies conducted in mice, rats, rabbits, and monkeys, increased rates of fetal structural abnormalities, intrauterine growth retardation, and embryo-fetal death occurred following administration of valproate to pregnant animals during organogenesis at clinically relevant doses (calculated on a body surface area [mg/m 2 ] basis). valproate induced malformations of multiple organ systems, including skeletal, cardiac, and urogenital defects. in mice, in addition to other malformations, fetal neural tube defects have been reported following valproate administration during critical periods of organogenesis, and the teratogenic response correlated with peak maternal drug levels. behavioral abnormalities (including cognitive, locomotor, and social interaction deficits) and brain histopathological changes have also been reported in mice and rat offspring exposed prenatally to clinically relevant doses of valproate. risk summary valproate is excreted in human milk. data in the published literature describe the presence of valproate in human milk (range: 0.4 mcg/ml to 3.9 mcg/ml), corresponding to 1% to 10% of maternal serum levels. valproate serum concentrations collected from breastfed infants aged 3 days postnatal to 12 weeks following delivery ranged from 0.7 mcg/ml to 4 mcg/ml, which were 1% to 6% of maternal serum valproate levels. a published study in children up to six years of age did not report adverse developmental or cognitive effects following exposure to valproate via breast milk [see data (human)].          there are no data to assess the effects of divalproex sodium delayed-release tablets on milk production or excretion. clinical considerations the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for divalproex sodium and any potential adverse effects on the breastfed infant from divalproex sodium or from the underlying maternal condition. monitor the breastfed infant for signs of liver damage including jaundice and unusual bruising or bleeding. there have been reports of hepatic failure and clotting abnormalities in offspring of women who used valproate during pregnancy [see use in specific populations (8.1)] . data human in a published study, breast milk and maternal blood samples were obtained from 11 epilepsy patients taking valproate at doses ranging from 300 mg/day to 2,400 mg/day on postnatal days 3 to 6. in 4 patients who were taking valproate only, breast milk contained an average valproate concentration of 1.8 mcg/ml (range: 1.1 mcg/ml to 2.2 mcg/ml), which corresponded to 4.8% of the maternal plasma concentration (range: 2.7% to 7.4%). across all patients (7 of whom were taking other aeds concomitantly), similar results were obtained for breast milk concentration (1.8 mcg/ml, range: 0.4 mcg/ml to 3.9 mcg/ml) and maternal plasma ratio (5.1%, range: 1.3% to 9.6%). a published study of 6 breastfeeding mother-infant pairs measured serum valproate levels during maternal treatment for bipolar disorder (750 mg/day or 1,000 mg/day). none of the mothers received valproate during pregnancy, and infants were aged from 4 weeks to 19 weeks at the time of evaluation. infant serum levels ranged from 0.7 mcg/ml to 1.5 mcg/ml. with maternal serum valproate levels near or within the therapeutic range, infant exposure was 0.9% to 2.3% of maternal levels. similarly, in 2 published case reports with maternal doses of 500 mg/day or 750 mg/day during breastfeeding of infants aged 3 months and 1 month, infant exposure was 1.5% and 6% that of the mother, respectively. a prospective observational multicenter study evaluated the long-term neurodevelopmental effects of aed use on children. pregnant women receiving monotherapy for epilepsy were enrolled with assessments of their children at ages 3 years and 6 years. mothers continued aed therapy during the breastfeeding period. adjusted iqs measured at 3 years for breastfed and non-breastfed children were 93 (n=11) and 90 (n=24), respectively. at 6 years, the scores for breastfed and non-breastfed children were 106 (n=11) and 94 (n=25), respectively (p=0.04). for other cognitive domains evaluated at 6 years, no adverse cognitive effects of continued exposure to an aed (including valproate) via breast milk were observed. contraception women of childbearing potential should use effective contraception while taking valproate [see boxed warning, warnings and precautions (5.4), drug interactions (7), and use in specific populations (8.1)] . this is especially important when valproate use is considered for a condition not usually associated with permanent injury or death such as prophylaxis of migraine headaches [see contraindications (4)] . infertility there have been reports of male infertility coincident with valproate therapy [see adverse reactions (6.4)] . in animal studies, oral administration of valproate at clinically relevant doses resulted in adverse reproductive effects in males [see nonclinical toxicology (13.1)] . experience has indicated that pediatric patients under the age of two years are at a considerably increased risk of developing fatal hepatotoxicity, especially those with the aforementioned conditions [see boxed warning and warnings and precautions (5.1)] . when divalproex sodium delayed-release tablets are used in this patient group, it should be used with extreme caution and as a sole agent. the benefits of therapy should be weighed against the risks. above the age of 2 years, experience in epilepsy has indicated that the incidence of fatal hepatotoxicity decreases considerably in progressively older patient groups. younger children, especially those receiving enzyme-inducing drugs, will require larger maintenance doses to attain targeted total and unbound valproate concentrations. pediatric patients (i.e., between 3 months and 10 years) have 50% higher clearances expressed on weight (i.e., ml/min/kg) than do adults. over the age of 10 years, children have pharmacokinetic parameters that approximate those of adults. the variability in free fraction limits the clinical usefulness of monitoring total serum valproic acid concentrations. interpretation of valproic acid concentrations in children should include consideration of factors that affect hepatic metabolism and protein binding. pediatric clinical trials divalproex sodium delayed-release tablets were studied in seven pediatric clinical trials. two of the pediatric studies were double-blinded placebo-controlled trials to evaluate the efficacy of divalproex sodium extended-release tablets for the indications of mania (150 patients aged 10 to 17 years, 76 of whom were on divalproex sodium extended-release tablets) and migraine (304 patients aged 12 to 17 years, 231 of whom were on divalproex sodium extended-release tablets). efficacy was not established for either the treatment of migraine or the treatment of mania. the most common drug-related adverse reactions (reported >5% and twice the rate of placebo) reported in the controlled pediatric mania study were nausea, upper abdominal pain, somnolence, increased ammonia, gastritis and rash. the remaining five trials were long term safety studies. two six-month pediatric studies were conducted to evaluate the long-term safety of divalproex sodium extended-release tablets for the indication of mania (292 patients aged 10 to 17 years). two twelve-month pediatric studies were conducted to evaluate the long-term safety of divalproex sodium extended-release tablets for the indication of migraine (353 patients aged 12 to 17 years). one twelve-month study was conducted to evaluate the safety of divalproex sodium sprinkle capsules in the indication of partial seizures (169 patients aged 3 to 10 years). in these seven clinical trials, the safety and tolerability of divalproex sodium delayed-release tablets in pediatric patients were shown to be comparable to those in adults [see adverse reactions (6)] . juvenile animal toxicology in studies of valproate in immature animals, toxic effects not observed in adult animals included retinal dysplasia in rats treated during the neonatal period (from postnatal day 4) and nephrotoxicity in rats treated during the neonatal and juvenile (from postnatal day 14) periods. the no-effect dose for these findings was less than the maximum recommended human dose on a mg/m 2 basis. no patients above the age of 65 years were enrolled in double-blind prospective clinical trials of mania associated with bipolar illness. in a case review study of 583 patients, 72 patients (12%) were greater than 65 years of age. a higher percentage of patients above 65 years of age reported accidental injury, infection, pain, somnolence, and tremor. discontinuation of valproate was occasionally associated with the latter two events. it is not clear whether these events indicate additional risk or whether they result from preexisting medical illness and concomitant medication use among these patients. a study of elderly patients with dementia revealed drug related somnolence and discontinuation for somnolence [see warnings and precautions ( 5.14)] . the starting dose should be reduced in these patients, and dosage reductions or discontinuation should be considered in patients with excessive somnolence [see dosage and administration ( 2.4)] . there is insufficient information available to discern the safety and effectiveness of valproate for the prophylaxis of migraines in patients over 65.
