remedyrepack inc. - quetiapine fumarate (unii: 2s3pl1b6uj) (quetiapine - unii:bgl0jsy5si) - quetiapine tablet is indicated for the treatment of schizophrenia. the efficacy of quetiapine tablets in schizophrenia was established in three 6-week trials in adults and one 6-week trial in adolescents (13 to 17 years). the effectiveness of quetiapine tablets for the maintenance treatment of schizophrenia has not been systematically evaluated in controlled clinical trials [see clinical studies (14.1)]. quetiapine tablet is indicated for the acute treatment of manic episodes associated with bipolar i disorder, both as monotherapy and as an adjunct to lithium or divalproex. efficacy was established in two 12-week monotherapy trials in adults, in one 3-week adjunctive trial in adults, and in one 3-week monotherapy trial in pediatric patients (10 to 17 years) [see clinical studies (14.2)] . quetiapine tablet is indicated as monotherapy for the acute treatment of depressive episodes associated with bipolar disorder. efficacy was established in two 8-week monotherapy trials in adult patients with bipolar i and bipolar ii disorder [see clinical studies (14.2)] . quetiapine tablet is indicated for the maintenance treatment of bipolar i disorder, as an adjunct to lithium or divalproex. efficacy was established in two maintenance trials in adults. the effectiveness of quetiapine tablets as monotherapy for the maintenance treatment of bipolar disorder has not been systematically evaluated in controlled clinical trials [see clinical studies (14.2)] . pediatric schizophrenia and bipolar i disorder are serious mental disorders, however, diagnosis can be challenging. for pediatric schizophrenia, symptom profiles can be variable, and for bipolar i disorder, patients may have variable patterns of periodicity of manic or mixed symptoms. it is recommended that medication therapy for pediatric schizophrenia and bipolar i disorder be initiated only after a thorough diagnostic evaluation has been performed and careful consideration given to the risks associated with medication treatment. medication treatment for both pediatric schizophrenia and bipolar i disorder is indicated as part of a total treatment program that often includes psychological, educational and social interventions. hypersensitivity to quetiapine or to any excipients in the quetiapine tablets formulation. anaphylactic reactions have been reported in patients treated with quetiapine tablets. pregnancy exposure registry there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including quetiapine, during pregnancy. healthcare providers are encouraged to register patients by contacting the national pregnancy registry for atypical antipsychotics at 1-866-961-2388 or online at http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/ risk summary neonates exposed to antipsychotic drugs (including quetiapine) during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms following delivery (see clinical considerations) . overall available data from published epidemiologic studies of pregnant women exposed to quetiapine have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see data) . there are risks to the mother associated with untreated schizophrenia, bipolar i, or major depressive disorder, and with exposure to antipsychotics, including quetiapine, during pregnancy (see clinical considerations) . in animal studies, embryo-fetal toxicity occurred including delays in skeletal ossification at approximately 1 and 2 times the maximum recommended human dose (mrhd) of 800 mg/day in both rats and rabbits, and an increased incidence of carpal/tarsal flexure (minor soft tissue anomaly) in rabbit fetuses at approximately 2 times the mrhd. in addition, fetal weights were decreased in both species. maternal toxicity (observed as decreased body weights and/or death) occurred at 2 times the mrhd in rats and approximately 1-2 times the mrhd in rabbits. the estimated background risk of major birth defects and miscarriage for the indicated populations is 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 disease-associated maternal and/or fetal risk there is a risk to the mother from untreated schizophrenia, or bipolar i disorder, including increased risk of relapse, hospitalization, and suicide. schizophrenia and bipolar i disorder are associated with increased adverse perinatal outcomes, including preterm birth. it is not known if this is a direct result of the illness or other comorbid factors. a prospective, longitudinal study followed 201 pregnant women with a history of major depressive disorder who were euthymic and 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 risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum. fetal/neonatal adverse reactions extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs, including quetiapine, during the third trimester of pregnancy. these symptoms varied in severity. monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. data human data published data from observational studies, birth registries, and case reports on the use of atypical antipsychotics during pregnancy do not report a clear association with antipsychotics and major birth defects. a retrospective cohort study from a medicaid database of 9258 women exposed to antipsychotics during pregnancy did not indicate an overall increased risk of major birth defects. animal data when pregnant rats and rabbits were exposed to quetiapine during organogenesis, there was no teratogenic effect in fetuses. doses were 25, 50 and 200 mg/kg in rats and 25, 50 and 100 mg/kg in rabbits which are approximately 0.3, 0.6 and 2-times (rats) and 0.6, 1 and 2-times (rabbits) the mrhd for schizophrenia of 800 mg/day based on mg/m2 body surface area. however, there was evidence of embryo-fetal toxicity including delays in skeletal ossification at approximately 1 and 2 times the mrhd of 800 mg/day in both rats and rabbits, and an increased incidence of carpal/tarsal flexure (minor soft tissue anomaly) in rabbit fetuses at approximately 2 times the mrhd. in addition, fetal weights were decreased in both species. maternal toxicity (observed as decreased body weights and/or death) occurred at 2 times the mrhd in rats and approximately 1-2 times the mrhd (all doses tested) in rabbits. in a peri/postnatal reproductive study in rats, no drug-related effects were observed when pregnant dams were treated with quetiapine at doses 0.01, 0.1, and 0.2 times the mrhd of 800 mg/day based on mg/m 2 body surface area. however, in a preliminary peri/postnatal study, there were increases in fetal and pup death, and decreases in mean litter weight at 3 times the mrhd. risk summary limited data from published literature report the presence of quetiapine in human breast milk at relative infant dose of <1% of the maternal weight-adjusted dosage. there are no consistent adverse events that have been reported in infants exposed to quetiapine through breast milk. there is no information on the effects of quetiapine on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for quetiapine and any potential adverse effects on the breastfed child from quetiapine or from the mother’s underlying condition. infertility females based on the pharmacologic action of quetiapine (d2 antagonism), treatment with quetiapine may result in an increase in serum prolactin levels, which may lead to a reversible reduction in fertility in females of reproductive potential [see warnings and precautions (5.15)] . in general, the adverse reactions observed in children and adolescents during the clinical trials were similar to those in the adult population with few exceptions. increases in systolic and diastolic blood pressure occurred in children and adolescents and did not occur in adults. orthostatic hypotension occurred more frequently in adults (4 to 7%) compared to children and adolescents (< 1%) [see warnings and precautions (5.7)and adverse reactions (6.1)]. schizophrenia the efficacy and safety of quetiapine in the treatment of schizophrenia in adolescents aged 13 to 17 years were demonstrated in one 6-week, double-blind, placebo-controlled trial [see indications and usage (1.1), dosage and administration (2.2), adverse reactions (6.1), and clinical studies (14.1)]. safety and effectiveness of quetiapine in pediatric patients less than 13 years of age with schizophrenia have not been established. maintenance the safety and effectiveness of quetiapine in the maintenance treatment of bipolar disorder has not been established in pediatric patients less than 18 years of age. the safety and effectiveness of quetiapine in the maintenance treatment of schizophrenia has not been established in any patient population, including pediatric patients. bipolar mania the efficacy and safety of quetiapine in the treatment of mania in children and adolescents ages 10 to 17 years with bipolar i disorder was demonstrated in a 3-week, double-blind, placebo-controlled, multicenter trial [see indications and usage (1.2), dosage and administration (2.3), adverse reactions (6.1), and clinical studies (14.2)]. safety and effectiveness of quetiapine in pediatric patients less than 10 years of age with bipolar mania have not been established. bipolar depression safety and effectiveness of quetiapine in pediatric patients less than 18 years of age with bipolar depression have not been established. a clinical trial with quetiapine extended release was conducted in children and adolescents (10 to 17 years of age) with bipolar depression, efficacy was not established. some differences in the pharmacokinetics of quetiapine were noted between children/adolescents (10 to 17 years of age) and adults. when adjusted for weight, the auc and cmax of quetiapine were 41% and 39% lower, respectively, in children and adolescents compared to adults. the pharmacokinetics of the active metabolite, norquetiapine, were similar between children/adolescents and adults after adjusting for weight [see clinical pharmacology (12.3)] . of the approximately 3700 patients in clinical studies with quetiapine, 7% (232) were 65 years of age or over. in general, there was no indication of any different tolerability of quetiapine in the elderly compared to younger adults. nevertheless, the presence of factors that might decrease pharmacokinetic clearance, increase the pharmacodynamic response to quetiapine, or cause poorer tolerance or orthostasis, should lead to consideration of a lower starting dose, slower titration, and careful monitoring during the initial dosing period in the elderly. the mean plasma clearance of quetiapine was reduced by 30% to 50% in elderly patients when compared to younger patients [see clinical pharmacology (12.3)and dosage and administration (2.3)] . clinical experience with quetiapine in patients with renal impairment is limited [see clinical pharmacology (12.3)] . since quetiapine is extensively metabolized by the liver, higher plasma levels are expected in patients with hepatic impairment. in this population, a low starting dose of 25 mg/day is recommended and the dose may be increased in increments of 25 mg/day to 50 mg/day [see dosage and administration (2.4)and clinical pharmacology (12.3)] . quetiapine is not a controlled substance. quetiapine has not been systematically studied, in animals or humans, for its potential for abuse, tolerance, or physical dependence. while the clinical trials did not reveal any tendency for any drug-seeking behavior, these observations were not systematic and it is not possible to predict on the basis of this limited experience the extent to which a cns-active drug will be misused, diverted, and/or abused once marketed. consequently, patients should be evaluated carefully for a history of drug abuse, and such patients should be observed closely for signs of misuse or abuse of quetiapine, e.g., development of tolerance, increases in dose, drug-seeking behavior.

there was no indication of any different tolerability of quetiapine in the elderly compared to younger adults. nevertheless, the presence of factors that might decrease pharmacokinetic clearance, increase the pharmacodynamic response to quetiapine, or cause poorer tolerance or orthostasis, should lead to consideration of a lower starting dose, slower titration, and careful monitoring during the initial dosing period in the elderly. the mean plasma clearance of quetiapine was reduced by 30% to 50% in elderly patients when compared to younger patients [see  clinical pharmacology (12.3)and dosage and administration (2.3)] . clinical experience with quetiapine in patients with renal impairment is limited [see clinical pharmacology (12.3)] . since quetiapine is extensively metabolized by the liver, higher plasma levels are expected in patients with hepatic impairment. in this population, a low starting dose of 25 mg/day is recommended and the dose may be increased in increments of 25 mg/day to 50 mg/day [see  dosage and administration (2.4)  and clinical pharmacology (12.3)] . quetiapine is not a controlled substance. quetiapine has not been systematically studied, in animals or humans, for its potential for abuse, tolerance, or physical dependence. while the clinical trials did not reveal any tendency for any drug-seeking behavior, these observations were not systematic and it is not possible to predict on the basis of this limited experience the extent to which a cns-active drug will be misused, diverted, and/or abused once marketed. consequently, patients should be evaluated carefully for a history of drug abuse, and such patients should be observed closely for signs of misuse or abuse of quetiapine, e.g., development of tolerance, increases in dose, drug-seeking behavior.

epidemiologic studies of pregnant women exposed to quetiapine have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see data). there are risks to the mother associated with untreated schizophrenia, bipolar i, or major depressive disorder, and with exposure to antipsychotics, including quetiapine, during pregnancy (see clinical considerations) . in animal studies, embryo-fetal toxicity occurred including delays in skeletal ossification at approximately 1 and 2 times the maximum recommended human dose (mrhd) of 800 mg/day in both rats and rabbits, and an increased incidence of carpal/tarsal flexure (minor soft tissue anomaly) in rabbit fetuses at approximately 2 times the mrhd. in addition, fetal weights were decreased in both species. maternal toxicity (observed as decreased body weights and/or death) occurred at 2 times the mrhd in rats and approximately 1 to 2 times the mrhd in rabbits. the estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. all pregnancies have a background risk of birth defect, loss, or other adverse outcomes. in the u.s. general

signs and symptoms of: - tendonitis - bursitis - acute gout the management of: - pain - primary dysmenorrhea naproxen tablets and naproxen sodium tablets are contraindicated in the following patients: - known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to naproxen or any components of the drug product [ see warnings and precautions ( 5.7, 5.9) ] - history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other nsaids. severe, sometimes fatal, anaphylactic reactions to nsaids have been reported in such patients [ see warnings and precautions ( 5.7, 5.8) ] - in the setting of coronary artery bypass graft (cabg) surgery [ see warnings and precautions ( 5.1) ] risk summary use of nsaids, including naproxen tablets and naproxen sodium tablets, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. because of these risks, limit dose and duration of naproxen tablets or naproxen sodium tablets use between about 20 and 30 weeks of gestation, and avoid naproxen tablets and naproxen sodium tablets use at about 30 weeks of gestation and later in pregnancy (see clinical considerations, data). premature closure of fetal ductus arteriosus use of nsaids, including naproxen tablets and naproxen sodium tablets, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus. oligohydramnios/neonatal renal impairment use of nsaids at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. data from observational studies regarding other potential embryofetal risks of nsaid use in women in the first or second trimesters of pregnancy are inconclusive. in animal reproduction studies in rats, rabbits, and mice no evidence of teratogenicity or fetal harm when naproxen was administered during the period of organogenesis at doses 0.13, 0.26, and 0.6 times the maximum recommended human daily dose of 1500 mg/day, respectively [ see data ]. based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. in animal studies, administration of prostaglandin synthesis inhibitors such as naproxen, resulted in increased pre-and post-implantation loss. prostaglandins also have been shown to have an important role in fetal kidney development. in published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses. the estimated background risk of major birth defects and miscarriage for the indicated population(s) is 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 premature closure of fetal ductus arteriosus: avoid use of nsaids in women at about 30 weeks gestation and later in pregnancy, because nsaids, including naproxen tablets and naproxen sodium tablets, can cause premature closure of the fetal ductus arteriosus (see data ). oligohydramnios/neonatal renal impairment: if an nsaid is necessary at about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective dose and shortest duration possible. if naproxen tablets or naproxen sodium tablets treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. if oligohydramnios occurs, discontinue naproxen tablets and naproxen sodium tablets, and follow up according to clinical practice (see data ). labor or delivery there are no studies on the effects of naproxen tablets or naproxen sodium tablets during labor or delivery. in animal studies, nsaids, including naproxen, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth. data human data there is some evidence to suggest that when inhibitors of prostaglandin synthesis are used to delay preterm labor, there is an increased risk of neonatal complications such as necrotizing enterocolitis, patent ductus arteriosus, and intracranial hemorrhage. naproxen treatment given in late pregnancy to delay parturition has been associated with persistent pulmonary hypertension, renal dysfunction, and abnormal prostaglandin e levels in preterm infants. because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly starting at 30-weeks of gestation, or third trimester) should be avoided. premature closure of fetal ductus arteriosus: published literature reports that the use of nsaids at about 30 weeks of gestation and later in pregnancy may cause premature closure of the fetal ductus arteriosus. oligohydramnios/neonatal renal impairment: published studies and postmarketing reports describe maternal nsaid use at about 20 weeks gestation or later in pregnancy associated with fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. these adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after nsaid initiation. in many cases, but not all, the decrease in amniotic fluid was transient and reversible with cessation of the drug. there have been a limited number of case reports of maternal nsaid use and neonatal renal dysfunction without oligohydramnios, some of which were irreversible. some cases of neonatal renal dysfunction required treatment with invasive procedures, such as exchange transfusion or dialysis. methodological limitations of these postmarketing studies and reports include lack of a control group; limited information regarding dose, duration, and timing of drug exposure; and concomitant use of other medications. these limitations preclude establishing a reliable estimate of the risk of adverse fetal and neonatal outcomes with maternal nsaid use. because the published safety data on neonatal outcomes involved mostly preterm infants, the generalizability of certain reported risks to the full-term infant exposed to nsaids through maternal use is uncertain. animal data reproduction studies have been performed in rats at 20 mg/kg/day (0.13 times the maximum recommended human daily dose of 1500 mg/day based on body surface area comparison), rabbits at 20 mg/kg/day (0.26 times the maximum recommended human daily dose, based on body surface area comparison), and mice at 170 mg/kg/day (0.6 times the maximum recommended human daily dose based on body surface area comparison) with no evidence of impaired fertility or harm to the fetus due to the drug. risk summary the naproxen anion has been found in the milk of lactating women at a concentration equivalent to approximately 1% of maximum naproxen concentration in plasma. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for naproxen tablets or naproxen sodium tablets and any potential adverse effects on the breastfed infant from the naproxen tablets or naproxen sodium tablets or from the underlying maternal condition. infertility females based on the mechanism of action, the use of prostaglandin-mediated nsaids, including naproxen tablets and naproxen sodium tablets, may delay or prevent rupture of ovarian follicles, which has been associated with reversible infertility in some women. published animal studies have shown that administration of prostaglandin synthesis inhibitors has the potential to disrupt prostaglandin-mediated follicular rupture required for ovulation. small studies in women treated with nsaids have also shown a reversible delay in ovulation. consider withdrawal of nsaids, including naproxen tablets and naproxen sodium tablets, in women who have difficulties conceiving or who are undergoing investigation of infertility. safety and effectiveness in pediatric patients below the age of 2 years have not been established. pediatric dosing recommendations for polyarticular juvenile idiopathic arthritis are based on well-controlled studies [ see dosage and administration ( 2) ]. there are no adequate effectiveness or dose-response data for other pediatric conditions, but the experience in polyarticular juvenile idiopathic arthritis and other use experience have established that single doses of 2.5 to 5 mg/kg as naproxen suspension, with total daily dose not exceeding 15 mg/kg/day, are well tolerated in pediatric patients over 2 years of age. the hepatic and renal tolerability of long-term naproxen administration was studied in two double-blind clinical trials involving 586 patients. of the patients studied, 98 patients were age 65 and older and 10 of the 98 patients were age 75 and older. naproxen was administered at doses of 375 mg twice daily or 750 mg twice daily for up to 6 months. transient abnormalities of laboratory tests assessing hepatic and renal function were noted in some patients, although there were no differences noted in the occurrence of abnormal values among different age groups. elderly patients, compared to younger patients, are at greater risk for nsaid-associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions. if the anticipated benefit for the elderly patient outweighs these potential risks, start dosing at the low end of the dosing range, and monitor patients for adverse effects [see warnings and precautions ( 5.1, 5.2, 5.3, 5.6, 5.14) ]. studies indicate that although total plasma concentration of naproxen is unchanged, the unbound plasma fraction of naproxen is increased in the elderly. the clinical significance of this finding is unclear, although it is possible that the increase in free naproxen concentration could be associated with an increase in the rate of adverse events per a given dosage in some elderly patients. caution is advised when high doses are required and some adjustment of dosage may be required in elderly patients. as with other drugs used in the elderly, it is prudent to use the lowest effective dose. experience indicates that geriatric patients may be particularly sensitive to certain adverse effects of nonsteroidal anti- inflammatory drugs. elderly or debilitated patients seem to tolerate peptic ulceration or bleeding less well when these events do occur. most spontaneous reports of fatal gi events are in the geriatric population [ see warnings and precautions ( 5.2) ]. naproxen is known to be substantially excreted by the kidney, and the risk of toxic 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 ( error! hyperlink reference not valid. ) ]. geriatric patients may be at a greater risk for the development of a form of renal toxicity precipitated by reduced prostaglandin formation during administration of nonsteroidal anti-inflammatory drugs [ see warnings and precautions ( 5.6) ]. caution is advised when high doses are required and some adjustment of dosage may be required in these patients. it is prudent to use the lowest effective dose [ see clinical pharmacology ( error! hyperlink reference not valid. ) ]. naproxen-containing products are not recommended for use in patients with moderate to severe and severe renal impairment (creatinine clearance <30 ml/min) [ see warnings and precautions ( 5.6), clinical pharmacology ( error! hyperlink reference not valid. ) ].

contraindicated in patients with known hypersensitivity to bupropion or other ingredients of bupropion hydrochloride extended-release tablets (xl). anaphylactoid/anaphylactic reactions and stevens-johnson syndrome have been reported [see warnings and precautions ( 5.8)]. pregnancy exposure registry there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy. healthcare providers are encouraged to register patients by calling the national pregnancy registry for antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/clinical-and-researchprograms/pregnancyregistry/antidepressants/. risk summary data from epidemiological studies of pregnant women exposed to bupropion in the first trimester have not identified an increased risk of congenital malformations overall (see data). there are risks to the mother associated with untreated depression (see clinical considerations). when bupropion was administered to pregnant rats during organogenesis, there was no evidence of fetal malformations at doses up to approximately 10 times the maximum recommended human dose (mrhd) of 450 mg/day. when given to pregnant rabbits during organogenesis, non-dose-related increases in incidence of fetal malformations and skeletal variations were observed at doses approximately equal to the mrhd and greater. decreased fetal weights were seen at doses twice the mrhd and greater (see animal data). the estimated background risk for major birth defects and miscarriage are unknown for the indicated population. all pregnancies have a background rate 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: a prospective, longitudinal study followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants during pregnancy 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 to the mother of untreated depression and potential effects on the fetus when discontinuing or changing treatment with antidepressant medications during pregnancy and postpartum. data 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. the registry was not designed or powered to evaluate specific defects but suggested a possible increase in cardiac malformations. 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, which has a limited number of exposed cases with cardiovascular malformations, and a case-controlled study (6,853 infants with cardiovascular malformations and 5,753 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 left ventricular outflow tract obstruction (lvoto) are inconsistent and do not allow conclusions regarding possible association. the united healthcare database lacked sufficient power to evaluate this association; the nbdps found increased risk for lvoto (n = 10; adjusted odds ratio (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 an 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 pregnant rats and rabbits, bupropion was administered orally during the period of organogenesis at doses of up to 450 and 150 mg/kg/day, respectively (approximately 10 and 6 times the mrhd, respectively, on a mg/m 2 basis). there was no evidence of fetal malformations in rats. when given to pregnant rabbits during organogenesis, nondose-related increases in incidence of fetal malformations and skeletal variations were observed at the lowest dose tested (25 mg/kg/day, approximately equal to the mrhd on a mg/m 2 basis) and greater. decreased fetal weights were observed at doses of 50 mg/kg/day (approximately 2 times the mrhd on a mg/m 2 basis) and greater. no maternal toxicity was evident at doses of 50 mg/kg/day or less. in a pre-and postnatal development study, bupropion administered orally to pregnant rats at doses of up to 150 mg/kg/day (approximately 3 times the mrhd on a mg/m 2 basis) from embryonic implantation through lactation had no effect on pup growth or development. risk summary data from published literature report the presence of bupropion and its metabolites in human milk (see data). there are no data on the effects of bupropion or its metabolites on milk production. limited data from postmarketing reports have not identified a clear association of adverse reactions in the breastfed infant. the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for bupropion hydrochloride extended-release tablets (xl) and any potential adverse effects on the breastfed child from bupropion hydrochloride extended-release tablets (xl) or from the underlying maternal condition. data in a lactation study of ten women, levels of orally dosed bupropion and its active metabolites were measured in expressed milk. the average daily infant exposure (assuming 150 ml/kg daily consumption) to bupropion and its active metabolites was 2% of the maternal weight-adjusted dose. postmarketing reports have described seizures in breastfed infants. the relationship of bupropion exposure and these seizures is unclear. safety and effectiveness in the pediatric population have not been established. when considering the use of bupropion hydrochloride extended-release tablets (xl) in a child or adolescent, balance the potential risks with the clinical need [see boxed warningand warnings and precautions ( 5.1)]. of the approximately 6000 patients who participated in clinical trials with bupropion hydrochloride sustained-release tablets (depression and smoking cessation studies), 275 were ≥65 years old and 47 were ≥75 years old. in addition, several hundred patients ≥65 years of age participated in clinical trials using the immediate-release formulation of bupropion hydrochloride (depression studies). 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 ( 2.7), use in specific populations ( 8.6), and clinical pharmacology ( 12.3)]. consider a reduced dose and/or dosing frequency of bupropion hydrochloride extended-release tablets (xl) in patients with renal impairment (glomerular filtration rate: <90 ml/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 ( 2.7) and clinical pharmacology ( 12.3)]. in patients with moderate to severe hepatic impairment (child-pugh score: 7 to 15), the maximum bupropion hydrochloride extended-release tablets (xl) dose is 150 mg every other day. 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 ( 2.6) and clinical pharmacology ( 12.3)]. bupropion is not a controlled substance. humans controlled clinical studies of bupropion hcl immediate-release conducted in normal volunteers, in subjects with a history of multiple drug abuse, and in depressed patients demonstrated an increase in motor activity and agitation/excitement. in a population of individuals experienced with drugs of abuse, a single dose of 400 mg bupropion produced mild amphetamine-like activity as compared to placebo on the morphine-benzedrine subscale of the addiction research center inventories (arci), and a score intermediate between placebo and amphetamine on the liking scale of the arci. these scales measure general feelings of euphoria and drug desirability. findings in clinical trials, however, are not known to reliably predict the abuse potential of drugs. nonetheless, evidence from single-dose studies does suggest that the recommended daily dosage of bupropion when administered in divided doses is not likely to be significantly reinforcing to amphetamine or cns stimulant abusers. however, higher doses (that could not be tested because of the risk of seizure) might be modestly attractive to those who abuse cns stimulant drugs. bupropion hydrochloride extended-release 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 behavioral 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.

urticaria, or other allergic-type reactions after taking aspirin or other nsaids. severe, sometimes fatal, anaphylactic reactions to nsaids have been reported in such patients [ see warnings and precautions ( 5.7, 5.8) ] - in the setting of coronary artery bypass graft (cabg) surgery [ see warnings and precautions ( 5.1) ] risk summary use of nsaids, including naproxen tablets and naproxen sodium tablets, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. because of these risks, limit dose and duration of naproxen tablets or naproxen sodium tablets use between about 20 and 30 weeks of gestation, and avoid naproxen tablets and naproxen sodium tablets use at about 30 weeks of gestation and later in pregnancy (see clinical considerations, data). premature closure of fetal ductus arteriosus use of nsaids, including naproxen tablets and naproxen sodium tablets, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus. oligohydramnios/neonatal renal impairment use of nsaids at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. data from observational studies regarding other potential embryofetal risks of nsaid use in women in the first or second trimesters of pregnancy are inconclusive. in animal reproduction studies in rats, rabbits, and mice no evidence of teratogenicity or fetal harm when naproxen was administered during the period of organogenesis at doses 0.13, 0.26, and 0.6 times the maximum recommended human daily dose of 1500 mg/day, respectively [ see data ]. based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. in animal studies, administration of prostaglandin synthesis inhibitors such as naproxen, resulted in increased pre-and post-implantation loss. prostaglandins also have been shown to have an important role in fetal kidney development. in published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses. the estimated background risk of major birth defects and miscarriage for the indicated population(s) is 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 premature closure of fetal ductus arteriosus: avoid use of nsaids in women at about 30 weeks gestation and later in pregnancy, because nsaids, including naproxen tablets and naproxen sodium tablets, can cause premature closure of the fetal ductus arteriosus (see data ). oligohydramnios/neonatal renal impairment: if an nsaid is necessary at about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective dose and shortest duration possible. if naproxen tablets or naproxen sodium tablets treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. if oligohydramnios occurs, discontinue naproxen tablets and naproxen sodium tablets, and follow up according to clinical practice (see data ). labor or delivery there are no studies on the effects of naproxen tablets or naproxen sodium tablets during labor or delivery. in animal studies, nsaids, including naproxen, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth. data human data there is some evidence to suggest that when inhibitors of prostaglandin synthesis are used to delay preterm labor, there is an increased risk of neonatal complications such as necrotizing enterocolitis, patent ductus arteriosus, and intracranial hemorrhage. naproxen treatment given in late pregnancy to delay parturition has been associated with persistent pulmonary hypertension, renal dysfunction, and abnormal prostaglandin e levels in preterm infants. because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly starting at 30-weeks of gestation, or third trimester) should be avoided. premature closure of fetal ductus arteriosus: published literature reports that the use of nsaids at about 30 weeks of gestation and later in pregnancy may cause premature closure of the fetal ductus arteriosus. oligohydramnios/neonatal renal impairment: published studies and postmarketing reports describe maternal nsaid use at about 20 weeks gestation or later in pregnancy associated with fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. these adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after nsaid initiation. in many cases, but not all, the decrease in amniotic fluid was transient and reversible with cessation of the drug. there have been a limited number of case reports of maternal nsaid use and neonatal renal dysfunction without oligohydramnios, some of which were irreversible. some cases of neonatal renal dysfunction required treatment with invasive procedures, such as exchange transfusion or dialysis. methodological limitations of these postmarketing studies and reports include lack of a control group; limited information regarding dose, duration, and timing of drug exposure; and concomitant use of other medications. these limitations preclude establishing a reliable estimate of the risk of adverse fetal and neonatal outcomes with maternal nsaid use. because the published safety data on neonatal outcomes involved mostly preterm infants, the generalizability of certain reported risks to the full-term infant exposed to nsaids through maternal use is uncertain. animal data reproduction studies have been performed in rats at 20 mg/kg/day (0.13 times the maximum recommended human daily dose of 1500 mg/day based on body surface area comparison), rabbits at 20 mg/kg/day (0.26 times the maximum recommended human daily dose, based on body surface area comparison), and mice at 170 mg/kg/day (0.6 times the maximum recommended human daily dose based on body surface area comparison) with no evidence of impaired fertility or harm to the fetus due to the drug. risk summary the naproxen anion has been found in the milk of lactating women at a concentration equivalent to approximately 1% of maximum naproxen concentration in plasma. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for naproxen tablets or naproxen sodium tablets and any potential adverse effects on the breastfed infant from the naproxen tablets or naproxen sodium tablets or from the underlying maternal condition. infertility females based on the mechanism of action, the use of prostaglandin-mediated nsaids, including naproxen tablets and naproxen sodium tablets, may delay or prevent rupture of ovarian follicles, which has been associated with reversible infertility in some women. published animal studies have shown that administration of prostaglandin synthesis inhibitors has the potential to disrupt prostaglandin-mediated follicular rupture required for ovulation. small studies in women treated with nsaids have also shown a reversible delay in ovulation. consider withdrawal of nsaids, including naproxen tablets and naproxen sodium tablets, in women who have difficulties conceiving or who are undergoing investigation of infertility. safety and effectiveness in pediatric patients below the age of 2 years have not been established. pediatric dosing recommendations for polyarticular juvenile idiopathic arthritis are based on well-controlled studies [ see dosage and administration ( 2) ]. there are no adequate effectiveness or dose-response data for other pediatric conditions, but the experience in polyarticular juvenile idiopathic arthritis and other use experience have established that single doses of 2.5 to 5 mg/kg as naproxen suspension, with total daily dose not exceeding 15 mg/kg/day, are well tolerated in pediatric patients over 2 years of age. the hepatic and renal tolerability of long-term naproxen administration was studied in two double-blind clinical trials involving 586 patients. of the patients studied, 98 patients were age 65 and older and 10 of the 98 patients were age 75 and older. naproxen was administered at doses of 375 mg twice daily or 750 mg twice daily for up to 6 months. transient abnormalities of laboratory tests assessing hepatic and renal function were noted in some patients, although there were no differences noted in the occurrence of abnormal values among different age groups. elderly patients, compared to younger patients, are at greater risk for nsaid-associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions. if the anticipated benefit for the elderly patient outweighs these potential risks, start dosing at the low end of the dosing range, and monitor patients for adverse effects [see warnings and precautions ( 5.1, 5.2, 5.3, 5.6, 5.14) ]. studies indicate that although total plasma concentration of naproxen is unchanged, the unbound plasma fraction of naproxen is increased in the elderly. the clinical significance of this finding is unclear, although it is possible that the increase in free naproxen concentration could be associated with an increase in the rate of adverse events per a given dosage in some elderly patients. caution is advised when high doses are required and some adjustment of dosage may be required in elderly patients. as with other drugs used in the elderly, it is prudent to use the lowest effective dose. experience indicates that geriatric patients may be particularly sensitive to certain adverse effects of nonsteroidal anti- inflammatory drugs. elderly or debilitated patients seem to tolerate peptic ulceration or

rabbits, bupropion was administered orally during the period of organogenesis at doses of up to 450 and 150 mg/kg/day, respectively (approximately 10 and 6 times the mrhd, respectively, on a mg/m 2 basis). there was no evidence of fetal malformations in rats. when given to pregnant rabbits during organogenesis, non-dose–related increases in incidence of fetal malformations and skeletal variations were observed at the lowest dose tested (25 mg/kg/day, approximately equal to the mrhd on a mg/m 2 basis) and greater. decreased fetal weights were observed at doses of 50 mg/kg/day (approximately 2 times the mrhd on a mg/m 2 basis) and greater. no maternal toxicity was evident at doses of 50 mg/kg/day or less. in a pre-and postnatal development study, bupropion administered orally to pregnant rats at doses of up to 150 mg/kg/day (approximately 3 times the mrhd on a mg/m 2 basis) from embryonic implantation through lactation had no effect on pup growth or development. risk summary   data from published literature report the presence of bupropion and its metabolites in human milk (see data). there are no data on the effects of bupropion or its metabolites on milk production. limited data from postmarketing reports have not identified a clear association of adverse reactions in the breastfed infant. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for bupropion hydrochloride tablets and any potential adverse effects on the breastfed child from bupropion hydrochloride tablets or from the underlying maternal condition.   data 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/kg daily consumption) to bupropion and its active metabolites was 2% of the maternal weight-adjusted dose. postmarketing reports have described seizures in breastfed infants. the relationship of bupropion exposure and these seizures is unclear. 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 (gfr less than 90 ml/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.

of: - tendonitis - bursitis - acute gout the management of: - pain - primary dysmenorrhea naproxen tablets and naproxen sodium tablets are contraindicated in the following patients: - known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to naproxen or any components of the drug product [ see warnings and precautions ( 5.7, 5.9) ] - history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other nsaids. severe, sometimes fatal, anaphylactic reactions to nsaids have been reported in such patients [ see warnings and precautions ( 5.7, 5.8) ] - in the setting of coronary artery bypass graft (cabg) surgery [ see warnings and precautions ( 5.1) ] risk summary use of nsaids, including naproxen tablets and naproxen sodium tablets, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. because of these risks, limit dose and duration of naproxen tablets or naproxen sodium tablets use between about 20 and 30 weeks of gestation, and avoid naproxen tablets and naproxen sodium tablets use at about 30 weeks of gestation and later in pregnancy (see clinical considerations, data). premature closure of fetal ductus arteriosus use of nsaids, including naproxen tablets and naproxen sodium tablets, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus. oligohydramnios/neonatal renal impairment use of nsaids at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. data from observational studies regarding other potential embryofetal risks of nsaid use in women in the first or second trimesters of pregnancy are inconclusive. in animal reproduction studies in rats, rabbits, and mice no evidence of teratogenicity or fetal harm when naproxen was administered during the period of organogenesis at doses 0.13, 0.26, and 0.6 times the maximum recommended human daily dose of 1500 mg/day, respectively [ see data ]. based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. in animal studies, administration of prostaglandin synthesis inhibitors such as naproxen, resulted in increased pre-and post-implantation loss. prostaglandins also have been shown to have an important role in fetal kidney development. in published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses. the estimated background risk of major birth defects and miscarriage for the indicated population(s) is 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 premature closure of fetal ductus arteriosus: avoid use of nsaids in women at about 30 weeks gestation and later in pregnancy, because nsaids, including naproxen tablets and naproxen sodium tablets, can cause premature closure of the fetal ductus arteriosus (see data ). oligohydramnios/neonatal renal impairment: if an nsaid is necessary at about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective dose and shortest duration possible. if naproxen tablets or naproxen sodium tablets treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. if oligohydramnios occurs, discontinue naproxen tablets and naproxen sodium tablets, and follow up according to clinical practice (see data ). labor or delivery there are no studies on the effects of naproxen tablets or naproxen sodium tablets during labor or delivery. in animal studies, nsaids, including naproxen, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth. data human data there is some evidence to suggest that when inhibitors of prostaglandin synthesis are used to delay preterm labor, there is an increased risk of neonatal complications such as necrotizing enterocolitis, patent ductus arteriosus, and intracranial hemorrhage. naproxen treatment given in late pregnancy to delay parturition has been associated with persistent pulmonary hypertension, renal dysfunction, and abnormal prostaglandin e levels in preterm infants. because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly starting at 30-weeks of gestation, or third trimester) should be avoided. premature closure of fetal ductus arteriosus: published literature reports that the use of nsaids at about 30 weeks of gestation and later in pregnancy may cause premature closure of the fetal ductus arteriosus. oligohydramnios/neonatal renal impairment: published studies and postmarketing reports describe maternal nsaid use at about 20 weeks gestation or later in pregnancy associated with fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. these adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after nsaid initiation. in many cases, but not all, the decrease in amniotic fluid was transient and reversible with cessation of the drug. there have been a limited number of case reports of maternal nsaid use and neonatal renal dysfunction without oligohydramnios, some of which were irreversible. some cases of neonatal renal dysfunction required treatment with invasive procedures, such as exchange transfusion or dialysis. methodological limitations of these postmarketing studies and reports include lack of a control group; limited information regarding dose, duration, and timing of drug exposure; and concomitant use of other medications. these limitations preclude establishing a reliable estimate of the risk of adverse fetal and neonatal outcomes with maternal nsaid use. because the published safety data on neonatal outcomes involved mostly preterm infants, the generalizability of certain reported risks to the full-term infant exposed to nsaids through maternal use is uncertain. animal data reproduction studies have been performed in rats at 20 mg/kg/day (0.13 times the maximum recommended human daily dose of 1500 mg/day based on body surface area comparison), rabbits at 20 mg/kg/day (0.26 times the maximum recommended human daily dose, based on body surface area comparison), and mice at 170 mg/kg/day (0.6 times the maximum recommended human daily dose based on body surface area comparison) with no evidence of impaired fertility or harm to the fetus due to the drug. risk summary the naproxen anion has been found in the milk of lactating women at a concentration equivalent to approximately 1% of maximum naproxen concentration in plasma. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for naproxen tablets or naproxen sodium tablets and any potential adverse effects on the breastfed infant from the naproxen tablets or naproxen sodium tablets or from the underlying maternal condition. infertility females based on the mechanism of action, the use of prostaglandin-mediated nsaids, including naproxen tablets and naproxen sodium tablets, may delay or prevent rupture of ovarian follicles, which has been associated with reversible infertility in some women. published animal studies have shown that administration of prostaglandin synthesis inhibitors has the potential to disrupt prostaglandin-mediated follicular rupture required for ovulation. small studies in women treated with nsaids have also shown a reversible delay in ovulation. consider withdrawal of nsaids, including naproxen tablets and naproxen sodium tablets, in women who have difficulties conceiving or who are undergoing investigation of infertility. safety and effectiveness in pediatric patients below the age of 2 years have not been established. pediatric dosing recommendations for polyarticular juvenile idiopathic arthritis are based on well-controlled studies [ see dosage and administration ( 2) ]. there are no adequate effectiveness or dose-response data for other pediatric conditions, but the experience in polyarticular juvenile idiopathic arthritis and other use experience have established that single doses of 2.5 to 5 mg/kg as naproxen suspension, with total daily dose not exceeding 15 mg/kg/day, are well tolerated in pediatric patients over 2 years of age. the hepatic and renal tolerability of long-term naproxen administration was studied in two double-blind clinical trials involving 586 patients. of the patients studied, 98 patients were age 65 and older and 10 of the 98 patients were age 75 and older. naproxen was administered at doses of 375 mg twice daily or 750 mg twice daily for up to 6 months. transient abnormalities of laboratory tests assessing hepatic and renal function were noted in some patients, although there were no differences noted in the occurrence of abnormal values among different age groups. elderly patients, compared to younger patients, are at greater risk for nsaid-associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions. if the anticipated benefit for the elderly patient outweighs these potential risks, start dosing at the low end of the dosing range, and monitor patients for adverse effects [see warnings and precautions ( 5.1, 5.2, 5.3, 5.6, 5.14) ]. studies indicate that although total plasma concentration of naproxen is unchanged, the unbound plasma fraction of naproxen is increased in the elderly. the clinical significance of this finding is unclear, although it is possible that the increase in free naproxen concentration could be associated with an increase in the rate of adverse events per a given dosage in some elderly patients. caution is advised when high doses are required and some adjustment of dosage may be required in elderly patients. as with other drugs used in the elderly, it is prudent to use the lowest effective dose. experience indicates that geriatric patients may be particularly sensitive to certain adverse effects of nonsteroidal anti- inflammatory drugs. elderly or debilitated patients seem to tolerate peptic ulceration or bleeding less well when these events do occur. most spontaneous reports of fatal gi events are in the geriatric population [ see warnings and precautions ( 5.2) ]. naproxen is known to be substantially excreted by the kidney, and the risk of toxic 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 ( error! hyperlink reference not valid. ) ]. geriatric patients may be at a greater risk for the development of a form of renal toxicity precipitated by reduced prostaglandin formation during administration of nonsteroidal anti-inflammatory drugs [ see warnings and precautions ( 5.6) ]. caution is advised when high doses are required and some adjustment of dosage may be required in these patients. it is prudent to use the lowest effective dose [ see clinical pharmacology ( error! hyperlink reference not valid. ) ]. naproxen-containing products are not recommended for use in patients with moderate to severe and severe renal impairment (creatinine clearance <30 ml/min) [ see warnings and precautions ( 5.6), clinical pharmacology ( error! hyperlink reference not valid. ) ].
