the management of the signs and symptoms of as [ see clinical studies (14.4) ]. for the management of acute pain in adults [ see clinical studies (14.5) ]. for the management of primary dysmenorrhea [ see clinical studies (14.5) ]. celecoxib capsules are contraindicated in the following patients: - known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to celecoxib, 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 cabg surgery [see warnings and precautions (5.1)] .  - in patients who have demonstrated allergic-type reactions to sulfonamides [see warnings and precautions (5.7)] . risk summary use of nsaids, including celecoxib capsules, 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 celecoxib capsules use between about 20 and 30 weeks of gestation and avoid celecoxib capsules 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 celecoxib capsules, 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, embryo-fetal deaths and an increase in diaphragmatic hernias were observed in rats administered celecoxib daily during the period of organogenesis at oral doses approximately 6 times the maximum recommended human dose (mrhd) of 200 mg twice daily. in addition, structural abnormalities (e.g., septal defects, ribs fused, sternebrae fused and sternebrae misshapen) were observed in rabbits given daily oral doses of celecoxib during the period of organogenesis at approximately 2 times the mrhd ( 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 celecoxib, resulted in increased pre- and postimplantation 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 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 celecoxib capsules, 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 celecoxib capsules treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. if oligohydramnios occurs, discontinue celecoxib capsules and follow up according to clinical practice ( see data ). labor or delivery there are no studies on the effects of celecoxib capsules during labor or delivery. in animal studies, nsaids, including celecoxib, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth. data human data the available data do not establish the presence or absence of developmental toxicity related to the use of celecoxib capsules. 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 celecoxib at oral doses ≥150 mg/kg/day (approximately 2 times the human exposure at 200 mg twice daily as measured by auc 0-24 ), caused an increased incidence of ventricular septal defects, a rare event, and fetal alterations, such as ribs fused, sternebrae fused and sternebrae misshapen when rabbits were treated throughout organogenesis. a dose-dependent increase in diaphragmatic hernias was observed when rats were given celecoxib at oral doses ≥30 mg/kg/day (approximately 6 times human exposure based on the auc 0-24 at 200 mg twice daily for ra) throughout organogenesis. in rats, exposure to celecoxib during early embryonic development resulted in pre-implantation and post-implantation losses at oral doses ≥50 mg/kg/day (approximately 6 times human exposure based on the auc 0-24 at 200 mg twice daily for ra). celecoxib produced no evidence of delayed labor or parturition at oral doses up to 100 mg/kg in rats (approximately 7-fold human exposure as measured by the auc 0-24 at 200 mg twice daily). the effects of celecoxib capsules on labor and delivery in pregnant women are unknown. risk summary limited data from 3 published reports that included a total of 12 breastfeeding women showed low levels of celecoxib capsules in breast milk. the calculated average daily infant dose was 10 to 40 mcg/kg/day, less than 1% of the weight-based therapeutic dose for a two-year old-child. a report of two breastfed infants 17 and 22 months of age did not show any adverse events. caution should be exercised when celecoxib capsules is administered to a nursing woman. the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for celecoxib capsules and any potential adverse effects on the breastfed infant from the celecoxib capsules or from the underlying maternal condition. infertility females based on the mechanism of action, the use of prostaglandin-mediated nsaids, including celecoxib capsules, 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 celecoxib capsules, in women who have difficulties conceiving or who are undergoing investigation of infertility. celecoxib capsules are approved for relief of the signs and symptoms of juvenile rheumatoid arthritis in patients 2 years and older. safety and efficacy have not been studied beyond six months in children. the long-term cardiovascular toxicity in children exposed to celecoxib capsules has not been evaluated and it is unknown if long-term risks may be similar to that seen in adults exposed to celecoxib or other cox-2 selective and non­selective nsaids [( see boxed warning, warnings and precautions(5.5) and clinical studies (14.3) ]. the use of celecoxib in patients 2 years to 17 years of age with pauciarticular, polyarticular course jra or in patients with systemic onset jra was studied in a 12-week, double-blind, active controlled, pharmacokinetic, safety and efficacy study, with a 12-week open-label extension. celecoxib has not been studied in patients under the age of 2 years, in patients with body weight less than 10 kg (22 lbs), and in patients with active systemic features. patients with systemic onset jra (without active systemic features) appear to be at risk for the development of abnormal coagulation laboratory tests. in some patients with systemic onset jra, both celecoxib and naproxen were associated with mild prolongation of activated partial thromboplastin time (aptt) but not prothrombin time (pt). when nsaids including celecoxib are used in patients with systemic onset jra, monitor patients for signs and symptoms of abnormal clotting or bleeding, due to the risk of disseminated intravascular coagulation. patients with systemic onset jra should be monitored for the development of abnormal coagulation tests [ see dosage and administration (2.4), warnings and precautions (5.15), adverse reactions (6.1), animal toxicology (13.2), clinical studies (14.3) ]. alternative therapies for treatment of jra should be considered in pediatric patients identified to be cyp2c9 poor metabolizers [see poor metabolizers of cyp2c9 substrates (8.8) ]. 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) ]. of the total number of patients who received celecoxib capsules in pre-approval clinical trials, more than 3,300 were 65-74 years of age, while approximately 1,300 additional patients were 75 years and over. no substantial differences in effectiveness were observed between these subjects and younger subjects. in clinical studies comparing renal function as measured by the gfr, bun and creatinine, and platelet function as measured by bleeding time and platelet aggregation, the results were not different between elderly and young volunteers. however, as with other nsaids, including those that selectively inhibit cox-2, there have been more spontaneous post-marketing reports of fatal gi events and acute renal failure in the elderly than in younger patients [ see warnings and precautions (5.2, 5.6) ]. the daily recommended dose of celecoxib capsules in patients with moderate hepatic impairment (child-pugh class b) should be reduced by 50%. the use of celecoxib capsules in patients with severe hepatic impairment is not recommended [ see dosage and administration (2.7) and clinical pharmacology (12.3) ]. celecoxib capsules is not recommended in patients with severe renal insufficiency [ see warnings and precautions (5.6)and clinical pharmacology (12.3) ]. in patients who are known or suspected to be poor cyp2c9 metabolizers (i.e., cyp2c9*3/*3), based on genotype or previous history/experience with other cyp2c9 substrates (such as warfarin, phenytoin) administer celecoxib capsules starting with half the lowest recommended dose. alternative management should be considered in jra patients identified to be cyp2c9 poor metabolizers. [ see dosage and administration (2.7) and clinical pharmacology (12.5) ].

doses 0.13, 0.26, and 0.6 times the maximum recommended human daily dose of 1,500 mg/day, respectively [ see data ]. based on animal data, prostaglandins have been shown to have an important role in

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.

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 mg/kg 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 (12.3) ]. 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 (12.3) ]. 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 (12.3) ].

depressive disorder (mdd), as defined by the diagnostic and statistical manual (dsm ) . the efficacy of bupropion in the treatment of a major depressive episode was established in two 4-week controlled inpatient trials and one 6-week controlled outpatient trial of adult subjects with mdd [see clinical studies(14)] . the efficacy of bupropion hydrochloride extended-release tablets, usp (sr) in maintaining an antidepressant response for up to 44 weeks following 8 weeks of acute treatment was demonstrated in a placebo-controlled trial [see clinical studies  (14)] . - bupropionhydrochloride extended-release tablets (sr) are contraindicated in patients with a seizure disorder. - bupropion hydrochloride extended-release tablets (sr) arecontraindicated in patients with a current or prior diagnosis of bulimia or anorexia nervosa as a higher incidence of seizures was observed in such patients treated with the immediate-release formulation of bupropion [see warnings and precautions (5.3)]. - bupropionhydrochloride extended-release tablets (sr) arecontraindicated in patients undergoing abrupt discontinuation of alcohol, benzodiazepines, barbiturates, and antiepileptic drugs [see warnings and precautions (5.3), drug interactions (7.3)] . - the use of maois (intended to treat psychiatric disorders) concomitantly with bupropion hydrochloride extended-release tablets (sr) or within 14 days of discontinuing treatment with bupropion hydrochloride extended-release tablets (sr) are contraindicated. there is an increased risk of hypertensive reactions when bupropion hydrochloride extended-release tablets (sr) are used concomitantly with maois. the use of bupropion hydrochloride extended-release tablets (sr) within 14 days of discontinuing treatment with an maoi is also contraindicated. starting bupropion hydrochloride extended-release tablets (sr) in a patient treated with reversible maois such as linezolid or intravenous methylene blue is contraindicated [see dosage and administration (2.4, 2.5), warnings and precautions (5.4), drug interactions (7.6)]. - bupropion hydrochloride extended-release tablets (sr) are contraindicated in patients with known hypersensitivity to bupropion or other ingredients of bupropion hydrochloride extended-release tablets (sr). anaphylactoid/anaphylactic reactions and stevens-johnson syndrome have been reported [see warnings and precautions (5.8)]. pregnancy exposure registry there is an independent pregnancy exposure registry that monitors pregnancy outcomes in women exposed to any 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 in pregnancy (see clinical considerations). when bupropion was administered to pregnant rats during organogenesis, there was no evidence of fetal malformations at doses up to approximately 11 times the maximum recommended human dose (mrhd) of 400 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 is unknown for the indicated population. 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 of 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 had a limited number of exposed cases with cardiovascular malformations, and a case-control study (6,853 infants with cardiovascular malformations and 5,763 with non-cardiovascular malformations) of self-reported bupropion use from the national birth defects prevention study (nbdps) did not show an increased risk for cardiovascular malformations overall after bupropion exposure during the first trimester. study findings on bupropion exposure during the first trimester and risk for left ventricular outflow tract obstruction (lvoto) are inconsistent and do not allow conclusions regarding a possible association. the united healthcare database lacked sufficient power to evaluate this association; the nbdps found increased risk for lvoto (n = 10; adjusted or = 2.6; 95% ci: 1.2, 5.7), and the slone epidemiology case control study did not find increased risk for lvoto. study findings on bupropion exposure during the first trimester and risk for ventricular septal defect (vsd) are inconsistent and do not allow conclusions regarding a possible association. the slone epidemiology study found an increased risk for vsd following first trimester maternal bupropion exposure (n = 17; adjusted or = 2.5; 95% ci: 1.3, 5.0) but did not find increased risk for any other cardiovascular malformations studied (including lvoto as above). the nbdps and united healthcare database study did not find an association between first trimester maternal bupropion exposure and vsd. for the findings of lvoto and vsd, the studies were limited by the small number of exposed cases, inconsistent findings among studies, and the potential for chance findings from multiple comparisons in case control studies. animal data: in studies conducted in 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 11 and 7 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 4 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 and any potential adverse effects on the breastfed child from bupropion 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 extended-release tablets (sr) 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 extended-release tablets (sr) is 100 mg/day or 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 (2.2), 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 extended-release tablets (sr) 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.

ankylosing spondylitis - polyarticular juvenile idiopathic arthritis - tendonitis - bursitis - acute gout the management of: - pain - primary dysmenorrhea naproxen 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 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 use between about 20 and 30 weeks of gestation, and avoid naproxen 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 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 1,500 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 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 treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. if oligohydramnios occurs, discontinue naproxen tablets, and follow up according to clinical practice (see data ). labor or delivery there are no studies on the effects of naproxen 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 1,500 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 and any potential adverse effects on the breastfed infant from the naproxen or from the underlying maternal condition. infertility females based on the mechanism of action, the use of prostaglandin-mediated nsaids, including naproxen 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, 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 mg/kg 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 (12.3) ]. 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 (12.3) ]. 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 (12.3) ].

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, embryo-fetal deaths and an increase in diaphragmatic hernias were observed in rats administered celecoxib daily during the period of organogenesis at oral doses approximately 6 times the maximum recommended human dose (mrhd) of 200 mg twice daily. in addition, structural abnormalities (e.g., septal defects, ribs fused, sternebrae fused and sternebrae misshapen) were observed in rabbits given daily oral doses of celecoxib during the period of organogenesis at approximately 2 times the mrhd ( see data ). based on animal data, prostaglandins have been shown to have an important role in endometrial vascular

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 celecoxib at oral doses ≥ 150 mg/kg/day (approximately 2 times the human exposure at 200 mg twice daily as measured by auc 0-24 ), caused an increased incidence of ventricular septal defects, a rare event, and fetal alterations, such as ribs fused, sternebrae fused and sternebrae misshapen when rabbits were treated throughout organogenesis. a dose-dependent increase in diaphragmatic hernias was observed when rats were given celecoxib at oral doses ≥ 30 mg/kg/day (approximately 6 times human exposure based on the auc 0-24 at 200 mg twice daily for ra) throughout organogenesis. in rats, exposure to celecoxib during early embryonic development resulted in pre-implantation and post-implantation losses at oral doses ≥ 50 mg/kg/ day (approximately 6 times human exposure based on the auc 0-24 at 200 mg twice daily for ra). celecoxib produced no evidence of delayed labor or parturition at oral doses up to 100 mg/kg in rats (approximately 7-fold human exposure as measured by the auc 0-24 at 200 mg twice daily). the effects of celecoxib on labor and delivery in pregnant women are unknown. risk summary limited data from 3 published reports that included a total of 12 breastfeeding women showed low levels of celecoxib in breast milk. the calculated average daily infant dose was 10 to 40 mcg/kg/day, less than 1% of the weight-based therapeutic dose for a two-year old-child. a report of two breastfed infants 17 and 22 months of age did not show any adverse events. caution should be exercised when celecoxib is administered to a nursing woman. the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for celecoxib and any potential adverse effects on the breastfed infant from the celecoxib or from the underlying maternal condition. infertility females based on the mechanism of action, the use of prostaglandin-mediated nsaids, including celecoxib,

signs and symptoms of juvenile rheumatoid arthritis in patients 2 years and older. safety and efficacy have not been studied beyond six months in children. the long-term cardiovascular toxicity in children exposed to celecoxib has not been evaluated and it is unknown if long-term risks may be similar to that seen in adults exposed to celecoxib or other cox-2 selective and non-selective nsaids [ see boxed warning, warnings and precautions (5.5), and clinical studies (14.3) ]. the use of celecoxib in patients 2 years to 17 years of age with pauciarticular, polyarticular course jra or in patients with systemic onset jra was studied in a 12-week, double-blind, active controlled, pharmacokinetic, safety and efficacy study, with a 12-week open-label extension. celecoxib has not been studied in patients under the age of 2 years, in patients with body weight less than 10 kg (22 lbs), and in patients with active systemic features. patients with systemic onset jra (without active systemic features) appear to be at risk for the development of abnormal coagulation laboratory tests. in some patients with systemic onset jra, both celecoxib and naproxen were associated with mild prolongation of activated partial thromboplastin time (aptt) but not prothrombin time (pt). when nsaids including celecoxib are used in patients with systemic onset jra, monitor patients for signs and symptoms of abnormal clotting or bleeding, due to the risk of disseminated intravascular coagulation. patients with systemic onset jra should be monitored for the development of abnormal coagulation tests [ see dosage and administration (2.4), warnings and precautions (5.15), adverse reactions (6.1), animal toxicology (13.2), and clinical studies (14.3) ]. alternative therapies for treatment of jra should be considered in pediatric patients identified to be cyp2c9 poor metabolizers [ see poor metabolizers of cyp2c9 substrates (8.8) ]. 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

in pre-approval clinical trials, more than 3,300 were 65 to 74 years of age, while approximately 1,300 additional patients were 75 years and over. no substantial differences in effectiveness were observed between these subjects and younger subjects. in clinical studies comparing renal function as measured by the gfr, bun and creatinine, and platelet function as measured by bleeding time and platelet aggregation, the results were not different between elderly and young volunteers. however, as with other nsaids, including those that selectively inhibit cox-2, there have been more spontaneous post-marketing reports of fatal gi events and acute renal failure in the elderly than in younger patients [ see warnings and precautions (5.2, 5.6) ]. the daily recommended dose of celecoxib capsules in patients with moderate hepatic impairment (child-pugh class b) should be reduced by 50%. the use of celecoxib in patients with severe hepatic impairment is not recommended [ see

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 sodium, during the third trimester of pregnancy increases the risk of premature closure of the fetal ductus arteriosus. avoid use of nsaids, including naproxen sodium, in pregnant women starting at 30 weeks of gestation (third trimester).   there are no adequate and well-controlled studies of naproxen sodium in pregnant women. data from observational studies regarding potential embryofetal risks of nsaid use in women in the first or second trimesters of pregnancy are inconclusive. in the general u.s. population, all clinically recognized pregnancies, regardless of drug exposure, have a background rate of 2 to 4% for major malformations, and 15 to 20% for pregnancy loss. 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. clinical considerations labor or delivery   there are no studies on the effects of naproxen sodium 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.   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. 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. 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 sodium and any potential adverse effects on the breastfed infant from the naproxen sodium or from the underlying maternal condition. infertility females based on the mechanism of action, the use of prostaglandin-mediated nsaids, including naproxen sodium, 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 sodium, 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, 5.6,5.13)].   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 ( 12.3)]. 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 ( 12.3)]. 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 ( 12.3)].

use of nsaids, including diclofenac sodium gel, 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 diclofenac sodium gel use between about 20 and 30 weeks of gestation and avoid diclofenac sodium gel use at about 30 weeks of gestation and later in pregnancy. 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. premature closure of fetal ductus arteriosus use of nsaids, including diclofenac sodium gel, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus. data from observational studies regarding other potential embryofetal risks of nsaid use in women in the first or

shortest duration possible. if diclofenac sodium gel treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. if oligohydramnios occurs, discontinue diclofenac sodium gel and follow up according to clinical practice. labor or delivery there are no studies on the effects of diclofenac sodium gel during labor or delivery. in animal studies, nsaids, including diclofenac, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth. data human data 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 the multiples provided in this labeling are based on an mrhd that assumes 10% bioavailability following topical application of 2 g diclofenac sodium gel per day (1 mg/kg diclofenac sodium). reproductive studies performed with diclofenac sodium alone at oral doses up to 20 mg/kg/day (15 times the mrhd based on body surface area (bsa) comparisons) in mice, 10 mg/kg/day (15 times the mrhd based on bsa comparisons) in rats, and 10 mg/kg/day (30 times the mrhd based on bsa comparisons) in rabbits have revealed no evidence of malformations despite the induction of maternal toxicity. in rats, maternally toxic doses were associated with dystocia, prolonged gestation, reduced fetal weights and growth, and reduced fetal survival. diclofenac has been shown to cross the placental barrier in mice and rats. risk summary data from published literature cases with oral preparations of diclofenac indicate the presence of small amounts of diclofenac in human milk. there are no data on the effects on the breastfed infant, or the effects on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for diclofenac sodium gel and any potential adverse effects on the breastfed infant from the diclofenac sodium gel or from the underlying maternal condition. data one woman treated orally with a diclofenac salt, 150 mg/day, had a milk diclofenac level of 100 mcg/l, equivalent to an infant dose of about 0.03 mg/kg/day. diclofenac was not detectable in breast milk in 12 women using diclofenac (after either 100 mg/day orally for 7 days or a single 50 mg intramuscular dose administered in the immediate postpartum period). the systemic bioavailability after topical application of diclofenac sodium gel is lower than after oral dosing [see clinical pharmacology ( 12.3)] . female infertility based on the mechanism of action, the use of prostaglandin mediated nsaids, including diclofenac

mg - buprenorphine and naloxone sublingual tablets are indicated for the maintenance treatment of opioid dependence. buprenorphine and naloxone sublingual tablets should be used as part of a complete treatment plan that includes counseling and psychosocial support. buprenorphine and naloxone sublingual tablets are contraindicated in patients with a history of hypersensitivity to  buprenorphine or naloxone as serious adverse reactions, including anaphylactic shock, have been reported [see warnings and precautions (5.9)] . risk summary the data on use of buprenorphine, one of the active ingredients in buprenorphine and naloxone sublingual tablets, in pregnancy, are limited; however, these data do not indicate  an increased risk of major malformations specifically due to buprenorphine exposure. there are limited data from randomized clinical trials in women maintained on buprenorphine that were not designed appropriately to assess the risk of major malformations [see data] . observational studies have reported on congenital malformations among buprenorphine-exposed pregnancies, but were also not designed appropriately to assess the risk of congenital malformations specifically due to buprenorphine exposure [see data] . the extremely limited data on sublingual naloxone exposure in pregnancy are not sufficient to evaluate a drug-associated risk. reproductive and developmental studies in rats and rabbits identified adverse events at clinically relevant and higher doses. embryo-fetal death was observed in both rats and rabbits administered buprenorphine during the period of organogenesis at doses approximately 6 and 0.3 times, respectively, the human sublingual dose of 16 mg/day of buprenorphine. pre- and post-natal development studies in rats demonstrated increased neonatal deaths at 0.3 times and above and dystocia at approximately 3 times the human sublingual dose of 16 mg/day of buprenorphine. no clear teratogenic effects were seen when buprenorphine was administered during organogenesis with a range of doses equivalent to or greater than the human sublingual dose of 16 mg/day of buprenorphine. however, increases in skeletal abnormalities were noted in rats and rabbits administered buprenorphine daily during organogenesis at doses approximately 0.6 times and approximately equal to the human sublingual dose of 16 mg/day of buprenorphine, respectively. in a few studies, some events such as acephalus and omphalocele were also observed but these findings were not clearly treatment-related [see data] . based on animal data, advise pregnant women of the potential risk to a fetus. the estimated background risks of major birth defects and miscarriage for the indicated population are unknown. all pregnancies have a background risk of birth defect, loss, or other adverse outcomes. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. clinical considerations disease-associated maternal and embryo-fetal risk untreated opioid addiction in pregnancy is associated with adverse obstetrical outcomes such as low birth weight, preterm birth, and fetal death. in addition, untreated opioid addiction often results in continued or relapsing illicit opioid use. dose adjustment during pregnancy and the postpartum period dosage adjustments of buprenorphine may be required during pregnancy, even if the patient was maintained on a stable dose prior to pregnancy. withdrawal signs and symptoms should be monitored closely and the dose adjusted as necessary. fetal/neonatal adverse reactions neonatal opioid withdrawal syndrome may occur in newborn infants of mothers who are receiving treatment with buprenorphine and naloxone sublingual tablets. neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea, and/or failure to gain weight. signs of neonatal withdrawal usually occur in the first days after birth. the duration and severity of neonatal opioid withdrawal syndrome may vary. observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly [see warnings and precautions (5.5)] . labor or delivery opioid-dependent women on buprenorphine maintenance therapy may require additional analgesia during labor. data human data studies have been conducted to evaluate neonatal outcomes in women exposed to buprenorphine during pregnancy. limited data from trials, observational studies, case series, and case reports on buprenorphine use in pregnancy do not indicate an increased risk of major malformations specifically due to buprenorphine. several factors may complicate the interpretation of investigations of the children of women who take buprenorphine during pregnancy, including maternal use of illicit drugs, late presentation for prenatal care, infection, poor compliance, poor nutrition, and psychosocial circumstances. interpretation of data is complicated further by the lack of information on untreated opioid-dependent pregnant women, who would be the most appropriate group for comparison. rather, women on another form of opioid medication-assisted treatment, or women in the general population are generally used as the comparison group. however, women in these comparison groups may be different from women prescribed buprenorphine-containing products with respect to maternal factors that may lead to poor pregnancy outcomes. in a multicenter, double-blind, randomized, controlled trial [maternal opioid treatment: human experimental research (mother)] designed primarily to assess neonatal opioid withdrawal effects, opioid-dependent pregnant women were randomized to buprenorphine (n=86) or methadone (n=89) treatment, with enrollment at an average gestational age of 18.7 weeks in both groups. a total of 28 of the 86 women in the buprenorphine group (33%) and 16 of the 89 women in the methadone group (18%) discontinued treatment before the end of pregnancy. among women who remained in treatment until delivery, there was no difference between buprenorphine-treated and methadone-treated groups in the number of neonates requiring nows treatment or in the peak severity of nows. buprenorphine-exposed neonates required less morphine (mean total dose, 1.1 mg vs. 10.4 mg), had shorter hospital stays (10 days vs. 17.5 days), and shorter duration of treatment for nows (4.1 days vs. 9.9 days) compared to the methadone-exposed group. there were no differences between groups in other primary outcomes (neonatal head circumference,) or secondary outcomes (weight and length at birth, preterm birth, gestational age at delivery, and 1-minute and 5-minute apgar scores), or in the rates of maternal or neonatal adverse events. the outcomes among mothers who discontinued treatment before delivery and may have relapsed to illicit opioid use are not known. because of the imbalance in discontinuation rates between the buprenorphine and methadone groups, the study findings are difficult to interpret. animal data the exposure margins listed below are based on body surface area comparisons (mg/m 2 ) to the human sublingual dose of 16 mg buprenorphine via buprenorphine and naloxone sublingual tablets. effects on embryo-fetal development were studied in sprague-dawley rats and russian white rabbits following oral (1:1) and intramuscular (im) (3:2) administration of mixtures of buprenorphine and naloxone during the period of organogenesis. following oral administration to rats no teratogenic effects were observed at buprenorphine doses up to 250 mg/kg/day (estimated exposure approximately 150 times the human sublingual dose of 16 mg) in the presence of maternal toxicity (mortality). following oral administration to rabbits, no teratogenic effects were observed at buprenorphine doses up to 40 mg/kg/day (estimated exposure approximately 50 times, the human sublingual dose of 16 mg) in the absence of clear maternal toxicity. no definitive drug-related teratogenic effects were observed in rats and rabbits at im doses up to 30 mg/kg/day (estimated exposure approximately 20 times and 35 times, respectively, the human sublingual dose of 16 mg). maternal toxicity resulting in mortality was noted in these studies in both rats and rabbits. acephalus was observed in one rabbit fetus from the low-dose group and omphalocele was observed in two rabbit fetuses from the same litter in the mid-dose group; no findings were observed in fetuses from the high-dose group. maternal toxicity was seen in the high-dose group but not at the lower doses where the findings were observed. following oral administration of buprenorphine to rats, dose-related post-implantation losses, evidenced by increases in the numbers of early resorptions with consequent reductions in the numbers of fetuses, were observed at doses of 10 mg/kg/day or greater (estimated exposure approximately 6 times the human sublingual dose of 16 mg). in the rabbit, increased post-implantation losses occurred at an oral dose of 40 mg/kg/day. following im administration in the rat and the rabbit, post-implantation losses, as evidenced by decreases in live fetuses and increases in resorptions, occurred at 30 mg/kg/day. buprenorphine was not teratogenic in rats or rabbits after im or subcutaneous (sc) doses up to 5 mg/kg/day (estimated exposure was approximately 3 and 6 times, respectively, the human sublingual dose of 16 mg), after iv doses up to 0.8 mg/kg/day (estimated exposure was approximately 0.5 times and equal to, respectively, the human sublingual dose of 16 mg), or after oral doses up to 160 mg/kg/day in rats (estimated exposure was approximately 95 times the human sublingual dose of 16 mg) and 25 mg/kg/day in rabbits (estimated exposure was approximately 30 times the human sublingual dose of 16 mg). significant increases in skeletal abnormalities (e.g., extra thoracic vertebra or thoraco-lumbar ribs) were noted in rats after sc administration of 1 mg/kg/day and up (estimated exposure was approximately 0.6 times the human sublingual dose of 16 mg), but were not observed at oral doses up to 160 mg/kg/day. increases in skeletal abnormalities in rabbits after im administration of 5 mg/kg/day (estimated exposure was approximately 6 times the human sublingual dose of 16 mg) in the absence of maternal toxicity or oral administration of 1 mg/kg/day or greater (estimated exposure was approximately equal to the human sublingual dose of 16 mg) were not statistically significant. in rabbits, buprenorphine produced statistically significant pre-implantation losses at oral doses of 1 mg/kg/day or greater and post-implantation losses that were statistically significant at iv doses of 0.2 mg/kg/day or greater (estimated exposure approximately 0.3 times the human sublingual dose of 16 mg). no maternal toxicity was noted at doses causing post-implantation loss in this study. dystocia was noted in pregnant rats treated intramuscularly with buprenorphine from gestation day 14 through lactation day 21 at 5 mg/kg/day (approximately 3 times the human sublingual dose of 16 mg). fertility, and pre- and postnatal development studies with buprenorphine in rats indicated increases in neonatal mortality after oral doses of 0.8 mg/kg/day and up (approximately 0.5 times the human sublingual dose of 16 mg), after im doses of 0.5 mg/kg/day and up (approximately 0.3 times the human sublingual dose of 16 mg), and after sc doses of 0.1 mg/kg/day and up (approximately 0.06 times the human sublingual dose of 16 mg). an apparent lack of milk production during these studies likely contributed to the decreased pup viability and lactation indices. delays in the occurrence of righting reflex and startle response were noted in rat pups at an oral dose of 80 mg/kg/day (approximately 50 times the human sublingual dose of 16 mg). risk summary based on two studies in 13 lactating women maintained on buprenorphine treatment, buprenorphine and its metabolite norbuprenorphine were present in low levels in human milk and available data have not shown adverse reactions in breastfed infants. there are no data on the combination product buprenorphine/naloxone in breastfeeding, however oral absorption of naloxone is limited.  the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for buprenorphine and naloxone sublingual tablets and any potential adverse effects on the breastfed child from the drug or from the underlying maternal condition. clinical considerations advise breastfeeding women taking buprenorphine products to monitor the infant for increased drowsiness and breathing difficulties. data data were consistent from two studies (n=13) of breastfeeding infants whose mothers were maintained on sublingual doses of buprenorphine ranging from 2.4 mg/day to 24 mg/day, showing that the infants were exposed to less than 1% of the maternal daily dose. in a study of six lactating women who were taking a median sublingual buprenorphine dose of 0.29 mg/kg/day 5 to 8 days after delivery, breast milk provided a median infant dose of 0.42 mcg/kg/day of buprenorphine and 0.33 mcg/kg/day of norbuprenorphine, equal to 0.2% and 0.12%, respectively, of the maternal weight-adjusted dose (relative dose/kg (%) of norbuprenorphine was calculated from the assumption that buprenorphine and norbuprenorphine are equipotent). data from a study of seven lactating women who were taking a median sublingual buprenorphine dose of 7 mg/day an average of 1.12 months after delivery indicated that the mean milk concentrations (c avg ) of buprenorphine and norbuprenorphine were 3.65 mcg/l and 1.94 mcg/l respectively. based on the study data, and assuming milk consumption of 150 ml/kg/day, an exclusively breastfed infant would receive an estimated mean absolute infant dose (aid) of 0.55 mcg/kg/day of buprenorphine and 0.29 mcg/kg/day of norbuprenorphine, or a mean relative infant dose (rid) of  0.38% and 0.18%, respectively, of the maternal weight-adjusted dose. infertility chronic use of opioids may cause reduced fertility in females and males of reproductive potential. it is not known whether these effects on fertility are reversible [see adverse reactions (6.2), clinical pharmacology (12.2) ,  nonclinical toxicology (13.1)] . the safety and effectiveness of buprenorphine and naloxone sublingual tablets have not been established in pediatric patients. this product is not appropriate for the treatment of neonatal abstinence syndrome in neonates, because it contains naloxone, an opioid antagonist. clinical studies of buprenorphine and naloxone sublingual tablets, buprenorphine and naloxone sublingual film, or buprenorphine sublingual tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they responded differently than younger subjects. other reported clinical experience has not identified differences in responses between the elderly and younger patients. due to possible decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy in geriatric patients, the decision to prescribe buprenorphine and naloxone sublingual tablets should be made cautiously in individuals 65 years of age or older and these patients should be monitored for signs and symptoms of toxicity or overdose. the effect of hepatic impairment on the pharmacokinetics of buprenorphine and naloxone has been evaluated in a pharmacokinetic study. both drugs are extensively metabolized in the liver. while no clinically significant changes have been observed in subjects with mild hepatic impairment; the plasma levels have been shown to be higher and half-life values have been shown to be longer for both buprenorphine and naloxone in subjects with moderate and severe hepatic impairment. the magnitude of the effects on naloxone are greater than that on buprenorphine in both moderately and severely impaired subjects. the difference in magnitude of the effects on naloxone and buprenorphine are greater in subjects with severe hepatic impairment than in subjects with moderate hepatic impairment, and therefore the clinical impact of these effects is likely to be greater in patients with severe hepatic impairment than in patients with moderate hepatic impairment. buprenorphine/naloxone products should be avoided in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment [see warnings and precautions (5.12), clinical pharmacology (12.3)] . no differences in buprenorphine pharmacokinetics were observed between 9 dialysis-dependent and 6 normal patients following iv administration of 0.3 mg buprenorphine. the effects of renal failure on naloxone pharmacokinetics are unknown. buprenorphine and naloxone sublingual tablets contain buprenorphine, a schedule iii controlled substance under the controlled substances act.   buprenorphine, like morphine and other opioids, has the potential for being abused and is subject to criminal diversion. this should be considered when prescribing or dispensing buprenorphine in situations when the clinician is concerned about an increased risk of misuse, abuse, or diversion. healthcare professionals should contact their state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product. patients who continue to misuse, abuse, or divert buprenorphine products or other opioids should be provided with, or referred to, more intensive and structured treatment. abuse of buprenorphine poses a risk of overdose and death. this risk is increased with the abuse of buprenorphine and alcohol and other substances, especially benzodiazepines. the healthcare provider may be able to more easily detect misuse or diversion by maintaining records of medication prescribed including date, dose, quantity, frequency of refills, and renewal requests of medication prescribed. proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper handling and storage of the medication are appropriate measures that help to limit abuse of opioid drugs. buprenorphine is a partial agonist at the mu-opioid receptor and chronic administration produces physical dependence of the opioid-type, characterized by moderate withdrawal signs and symptoms upon abrupt discontinuation or rapid taper. the withdrawal syndrome is typically milder than seen with full agonists and may be delayed in onset [see warnings and precautions (5.7)] . neonatal opioid withdrawal syndrome (nows) is an expected and treatable outcome of prolonged use of opioids during pregnancy [see warnings and precautions (5.5)] . buprenorphine (bue” pre nor’ feen) and naloxone (nal
