american health packaging - divalproex sodium (unii: 644vl95ao6) (valproic acid - unii:614oi1z5wi) - valproic acid 125 mg - divalproex sodium delayed-release tablets are a valproate and are indicated for the treatment of the manic episodes associated with bipolar disorder. a manic episode is a distinct period of abnormally and persistently elevated, expansive, or irritable mood. typical symptoms of mania include pressure of speech, motor hyperactivity, reduced need for sleep, flight of ideas, grandiosity, poor judgment, aggressiveness, and possible hostility. the efficacy of divalproex sodium delayed-release tablets was established in 3-week trials with patients meeting dsm-iii-r criteria for bipolar disorder who were hospitalized for acute mania [see clinical studies (14.1)]. the safety and effectiveness of divalproex sodium delayed-release tablets for long-term use in mania, i.e., more than 3 weeks, has not been demonstrated in controlled clinical trials. therefore, healthcare providers who elect to use divalproex sodium delayed-release tablets for extended periods should continually reevaluate the long-term usefulness of the drug for the individual patient. divalproex sodium delayed-release tablets are indicated as monotherapy and adjunctive therapy in the treatment of patients with complex partial seizures that occur either in isolation or in association with other types of seizures. divalproex sodium delayed-release tablets are also indicated for use as sole and adjunctive therapy in the treatment of simple and complex absence seizures, and adjunctively in patients with multiple seizure types that include absence seizures. simple absence is defined as very brief clouding of the sensorium or loss of consciousness accompanied by certain generalized epileptic discharges without other detectable clinical signs. complex absence is the term used when other signs are also present. divalproex sodium delayed-release tablets are indicated for prophylaxis of migraine headaches. there is no evidence that divalproex sodium delayed-release tablets are useful in the acute treatment of migraine headaches. because of the risk to the fetus of decreased iq, neurodevelopmental disorders, neural tube defects, and other major congenital malformations, which may occur very early in pregnancy, valproate should not be used to treat women with epilepsy or bipolar disorder who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable. valproate should not be administered to a woman of childbearing potential unless other medications have failed to provide adequate symptom control or are otherwise unacceptable [see warnings and precautions (5.2, 5.3, 5.4), use in specific populations (8.1), and patient counseling information (17)]. for prophylaxis of migraine headaches, divalproex sodium delayed-release tablets are contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see contraindications (4)]. - divalproex sodium delayed-release tablets should not be administered to patients with hepatic disease or significant hepatic dysfunction [see warnings and precautions (5.1)]. - divalproex sodium delayed-release tablets are contraindicated in patients known to have mitochondrial disorders caused by mutations in mitochondrial dna polymerase γ (polg; e.g., alpers-huttenlocher syndrome) and children under two years of age who are suspected of having a polg-related disorder [see warnings and precautions (5.1)]. - divalproex sodium delayed-release tablets are contraindicated in patients with known hypersensitivity to the drug [see warnings and precautions (5.12)]. - divalproex sodium delayed-release tablets are contraindicated in patients with known urea cycle disorders [see warnings and precautions (5.6)]. - for use in prophylaxis of migraine headaches: divalproex sodium delayed-release tablets are contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see warnings and precautions (5.2, 5.3, 5.4) and use in specific populations (8.1)]. pregnancy exposure registry there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (aeds), including divalproex sodium delayed-release tablets, during pregnancy. encourage women who are taking divalproex sodium delayed-release tablets during pregnancy to enroll in the north american antiepileptic drug (naaed) pregnancy registry by calling toll-free 1-888-233-2334 or visiting the website, http://www.aedpregnancyregistry.org/. this must be done by the patient herself. risk summary for use in prophylaxis of migraine headaches, valproate is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see contraindications (4)]. for use in epilepsy or bipolar disorder, valproate should not be used to treat women who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable [see boxed warning and warnings and precautions (5.2, 5.3)]. women with epilepsy who become pregnant while taking valproate should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life. maternal valproate use during pregnancy for any indication increases the risk of congenital malformations, particularly neural tube defects including spina bifida, but also malformations involving other body systems (e.g., craniofacial defects including oral clefts, cardiovascular malformations, hypospadias, limb malformations). this risk is dose-dependent; however, a threshold dose below which no risk exists cannot be established. in utero exposure to valproate may also result in hearing impairment or hearing loss. valproate polytherapy with other aeds has been associated with an increased frequency of congenital malformations compared with aed monotherapy. the risk of major structural abnormalities is greatest during the first trimester; however, other serious developmental effects can occur with valproate use throughout pregnancy. the rate of congenital malformations among babies born to epileptic mothers who used valproate during pregnancy has been shown to be about four times higher than the rate among babies born to epileptic mothers who used other anti-seizure monotherapies [see warnings and precautions (5.2) and data (human)] . epidemiological studies have indicated that children exposed to valproate in utero have lower iq scores and a higher risk of neurodevelopmental disorders compared to children exposed to either another aed in utero or to no aeds in utero [see warnings and precautions (5.3) and data (human)] . an observational study has suggested that exposure to valproate products during pregnancy increases the risk of autism spectrum disorders [see data (human)] . in animal studies, valproate administration during pregnancy resulted in fetal structural malformations similar to those seen in humans and neurobehavioral deficits in the offspring at clinically relevant doses [see data (animal)] . there have been reports of hypoglycemia in neonates and fatal cases of hepatic failure in infants following maternal use of valproate during pregnancy. pregnant women taking valproate may develop hepatic failure or clotting abnormalities including thrombocytopenia, hypofibrinogenemia, and/or decrease in other coagulation factors, which may result in hemorrhagic complications in the neonate including death [see warnings and precautions (5.1, 5.8)] . available prenatal diagnostic testing to detect neural tube and other defects should be offered to pregnant women using valproate. evidence suggests that folic acid supplementation prior to conception and during the first trimester of pregnancy decreases the risk for congenital neural tube defects in the general population. it is not known whether the risk of neural tube defects or decreased iq in the offspring of women receiving valproate is reduced by folic acid supplementation. dietary folic acid supplementation both prior to conception and during pregnancy should be routinely recommended for patients using valproate [see warnings and precautions (5.2, 5.4)] . all pregnancies have a background risk of birth defect, loss, or other adverse outcomes. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. clinical considerations disease-associated maternal and/or embryo/fetal risk to prevent major seizures, women with epilepsy should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life. even minor seizures may pose some hazard to the developing embryo or fetus [see warnings and precautions (5.4)] . however, discontinuation of the drug may be considered prior to and during pregnancy in individual cases if the seizure disorder severity and frequency do not pose a serious threat to the patient. maternal adverse reactions pregnant women taking valproate may develop clotting abnormalities including thrombocytopenia, hypofibrinogenemia, and/or decrease in other coagulation factors, which may result in hemorrhagic complications in the neonate including death [see warnings and precautions (5.8)] . if valproate is used in pregnancy, the clotting parameters should be monitored carefully in the mother. if abnormal in the mother, then these parameters should also be monitored in the neonate. patients taking valproate may develop hepatic failure [see boxed warning and warnings and precautions (5.1)] . fatal cases of hepatic failure in infants exposed to valproate in utero have also been reported following maternal use of valproate during pregnancy. hypoglycemia has been reported in neonates whose mothers have taken valproate during pregnancy. data human neural tube defects and other structural abnormalities there is an extensive body of evidence demonstrating that exposure to valproate in utero increases the risk of neural tube defects and other structural abnormalities. based on published data from the cdc’s national birth defects prevention network, the risk of spina bifida in the general population is about 0.06 to 0.07% (6 to 7 in 10,000 births) compared to the risk following in utero valproate exposure estimated to be approximately 1 to 2% (100 to 200 in 10,000 births). the naaed pregnancy registry has reported a major malformation rate of 9 to 11% in the offspring of women exposed to an average of 1,000 mg/day of valproate monotherapy during pregnancy. these data show an up to a five-fold increased risk for any major malformation following valproate exposure in utero compared to the risk following exposure in utero to other aeds taken as monotherapy. the major congenital malformations included cases of neural tube defects, cardiovascular malformations, craniofacial defects (e.g., oral clefts, craniosynostosis), hypospadias, limb malformations (e.g., clubfoot, polydactyly), and other malformations of varying severity involving other body systems [see warnings and precautions (5.2)] . effect on iq and neurodevelopmental effects published epidemiological studies have indicated that children exposed to valproate in utero have lower iq scores than children exposed to either another aed in utero or to no aeds in utero . the largest of these studies 1 is a prospective cohort study conducted in the united states and united kingdom that found that children with prenatal exposure to valproate (n=62) had lower iq scores at age 6 (97 [95% c.i. 94 to 101]) than children with prenatal exposure to the other anti-epileptic drug monotherapy treatments evaluated: lamotrigine (108 [95% c.i. 105 to 110]), carbamazepine (105 [95% c.i. 102 to 108]) and phenytoin (108 [95% c.i. 104 to 112]). it is not known when during pregnancy cognitive effects in valproate-exposed children occur. because the women in this study were exposed to aeds throughout pregnancy, whether the risk for decreased iq was related to a particular time period during pregnancy could not be assessed [see warnings and precautions (5.3)] . although the available studies have methodological limitations, the weight of the evidence supports a causal association between valproate exposure in utero and subsequent adverse effects on neurodevelopment, including increases in autism spectrum disorders and attention deficit/hyperactivity disorder (adhd). an observational study has suggested that exposure to valproate products during pregnancy increases the risk of autism spectrum disorders. in this study, children born to mothers who had used valproate products during pregnancy had 2.9 times the risk (95% confidence interval [ci]: 1.7 to 4.9) of developing autism spectrum disorders compared to children born to mothers not exposed to valproate products during pregnancy. the absolute risks for autism spectrum disorders were 4.4% (95% ci: 2.6% to 7.5%) in valproate-exposed children and 1.5% (95% ci: 1.5% to 1.6%) in children not exposed to valproate products. another observational study found that children who were exposed to valproate in utero had an increased risk of adhd (adjusted hr 1.48; 95% ci, 1.09 to 2.00) compared with the unexposed children. because these studies were observational in nature, conclusions regarding a causal association between in utero valproate exposure and an increased risk of autism spectrum disorder and adhd cannot be considered definitive. other there are published case reports of fatal hepatic failure in offspring of women who used valproate during pregnancy. animal in developmental toxicity studies conducted in mice, rats, rabbits, and monkeys, increased rates of fetal structural abnormalities, intrauterine growth retardation, and embryo-fetal death occurred following administration of valproate to pregnant animals during organogenesis at clinically relevant doses (calculated on a body surface area [mg/m 2 ] basis). valproate induced malformations of multiple organ systems, including skeletal, cardiac, and urogenital defects. in mice, in addition to other malformations, fetal neural tube defects have been reported following valproate administration during critical periods of organogenesis, and the teratogenic response correlated with peak maternal drug levels. behavioral abnormalities (including cognitive, locomotor, and social interaction deficits) and brain histopathological changes have also been reported in mice and rat offspring exposed prenatally to clinically relevant doses of valproate. risk summary valproate is excreted in human milk. data in the published literature describe the presence of valproate in human milk (range: 0.4 mcg/ml to 3.9 mcg/ml), corresponding to 1% to 10% of maternal serum levels. valproate serum concentrations collected from breastfed infants aged 3 days postnatal to 12 weeks following delivery ranged from 0.7 mcg/ml to 4 mcg/ml, which were 1% to 6% of maternal serum valproate levels. a published study in children up to six years of age did not report adverse developmental or cognitive effects following exposure to valproate via breast milk [see data (human)] . there are no data to assess the effects of divalproex sodium delayed-release tablets on milk production or excretion. clinical considerations the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for divalproex sodium delayed-release tablets and any potential adverse effects on the breastfed infant from divalproex sodium delayed-release tablets or from the underlying maternal condition. monitor the breastfed infant for signs of liver damage including jaundice and unusual bruising or bleeding. there have been reports of hepatic failure and clotting abnormalities in offspring of women who used valproate during pregnancy [see use in specific populations (8.1)] . data human in a published study, breast milk and maternal blood samples were obtained from 11 epilepsy patients taking valproate at doses ranging from 300 mg/day to 2,400 mg/day on postnatal days 3 to 6. in 4 patients who were taking valproate only, breast milk contained an average valproate concentration of 1.8 mcg/ml (range: 1.1 mcg/ml to 2.2 mcg/ml), which corresponded to 4.8% of the maternal plasma concentration (range: 2.7% to 7.4%). across all patients (7 of whom were taking other aeds concomitantly), similar results were obtained for breast milk concentration (1.8 mcg/ml, range: 0.4 mcg/ml to 3.9 mcg/ml) and maternal plasma ratio (5.1%, range: 1.3% to 9.6%). a published study of 6 breastfeeding mother-infant pairs measured serum valproate levels during maternal treatment for bipolar disorder (750 mg/day or 1,000 mg/day). none of the mothers received valproate during pregnancy, and infants were aged from 4 weeks to 19 weeks at the time of evaluation. infant serum levels ranged from 0.7 mcg/ml to 1.5 mcg/ml. with maternal serum valproate levels near or within the therapeutic range, infant exposure was 0.9% to 2.3% of maternal levels. similarly, in 2 published case reports with maternal doses of 500 mg/day or 750 mg/day during breastfeeding of infants aged 3 months and 1 month, infant exposure was 1.5% and 6% that of the mother, respectively. a prospective observational multicenter study evaluated the long-term neurodevelopmental effects of aed use on children. pregnant women receiving monotherapy for epilepsy were enrolled with assessments of their children at ages 3 years and 6 years. mothers continued aed therapy during the breastfeeding period. adjusted iqs measured at 3 years for breastfed and non-breastfed children were 93 (n=11) and 90 (n=24), respectively. at 6 years, the scores for breastfed and non-breastfed children were 106 (n=11) and 94 (n=25), respectively (p=0.04). for other cognitive domains evaluated at 6 years, no adverse cognitive effects of continued exposure to an aed (including valproate) via breast milk were observed. contraception women of childbearing potential should use effective contraception while taking valproate [see boxed warning, warnings and precautions (5.4), drug interactions (7), and use in specific populations (8.1)] . this is especially important when valproate use is considered for a condition not usually associated with permanent injury or death such as prophylaxis of migraine headaches [see contraindications (4)] . infertility there have been reports of male infertility coincident with valproate therapy [see adverse reactions (6.4)] . in animal studies, oral administration of valproate at clinically relevant doses resulted in adverse reproductive effects in males [see nonclinical toxicology (13.1)] . experience has indicated that pediatric patients under the age of two years are at a considerably increased risk of developing fatal hepatotoxicity, especially those with the aforementioned conditions [see boxed warning and warnings and precautions (5.1)] . when divalproex sodium delayed-release tablets are used in this patient group, it should be used with extreme caution and as a sole agent. the benefits of therapy should be weighed against the risks. above the age of 2 years, experience in epilepsy has indicated that the incidence of fatal hepatotoxicity decreases considerably in progressively older patient groups. younger children, especially those receiving enzyme-inducing drugs, will require larger maintenance doses to attain targeted total and unbound valproate concentrations. pediatric patients (i.e., between 3 months and 10 years) have 50% higher clearances expressed on weight (i.e., ml/min/kg) than do adults. over the age of 10 years, children have pharmacokinetic parameters that approximate those of adults. the variability in free fraction limits the clinical usefulness of monitoring total serum valproic acid concentrations. interpretation of valproic acid concentrations in children should include consideration of factors that affect hepatic metabolism and protein binding. pediatric clinical trials divalproex sodium was studied in seven pediatric clinical trials. two of the pediatric studies were double-blinded placebo-controlled trials to evaluate the efficacy of divalproex sodium er for the indications of mania (150 patients aged 10 to 17 years, 76 of whom were on divalproex sodium er) and migraine (304 patients aged 12 to 17 years, 231 of whom were on divalproex sodium er). efficacy was not established for either the treatment of migraine or the treatment of mania. the most common drug-related adverse reactions (reported >5% and twice the rate of placebo) reported in the controlled pediatric mania study were nausea, upper abdominal pain, somnolence, increased ammonia, gastritis and rash. the remaining five trials were long term safety studies. two six-month pediatric studies were conducted to evaluate the long-term safety of divalproex sodium er for the indication of mania (292 patients aged 10 to 17 years). two twelve-month pediatric studies were conducted to evaluate the long-term safety of divalproex sodium er for the indication of migraine (353 patients aged 12 to 17 years). one twelve-month study was conducted to evaluate the safety of divalproex sodium sprinkle capsules in the indication of partial seizures (169 patients aged 3 to 10 years). in these seven clinical trials, the safety and tolerability of divalproex sodium in pediatric patients were shown to be comparable to those in adults [see adverse reactions (6)] . juvenile animal toxicology in studies of valproate in immature animals, toxic effects not observed in adult animals included retinal dysplasia in rats treated during the neonatal period (from postnatal day 4) and nephrotoxicity in rats treated during the neonatal and juvenile (from postnatal day 14) periods. the no-effect dose for these findings was less than the maximum recommended human dose on a mg/m 2 basis. no patients above the age of 65 years were enrolled in double-blind prospective clinical trials of mania associated with bipolar illness. in a case review study of 583 patients, 72 patients (12%) were greater than 65 years of age. a higher percentage of patients above 65 years of age reported accidental injury, infection, pain, somnolence, and tremor. discontinuation of valproate was occasionally associated with the latter two events. it is not clear whether these events indicate additional risk or whether they result from preexisting medical illness and concomitant medication use among these patients. a study of elderly patients with dementia revealed drug related somnolence and discontinuation for somnolence [see warnings and precautions (5.14)] . the starting dose should be reduced in these patients, and dosage reductions or discontinuation should be considered in patients with excessive somnolence [see dosage and administration (2.4)] . there is insufficient information available to discern the safety and effectiveness of valproate for the prophylaxis of migraines in patients over 65.

decreased iq, neurodevelopmental disorders, neural tube defects, and other major congenital malformations, which may occur very early in pregnancy, valproate should not be used to treat women with epilepsy or bipolar disorder who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable. valproate should

women of childbearing potential who are not using effective contraception [see contraindications (4)]. for use in epilepsy or bipolar disorder, valproate should not be used to treat women who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable [see boxed warning and warnings and precautions (5.2, 5.3)]. women with epilepsy who become pregnant while taking valproate should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life. maternal valproate use during pregnancy for any indication increases the risk of congenital malformations, particularly neural tube defects including spina bifida, but also malformations involving other body systems (e.g., craniofacial defects including oral clefts, cardiovascular malformations, hypospadias, limb malformations). this risk is dose-dependent; however, a threshold dose below which no risk exists cannot be established. in utero exposure to valproate may also result in hearing impairment or hearing loss. valproate polytherapy with other aeds has been associated with an increased frequency of congenital malformations compared with aed monotherapy. the risk of major structural abnormalities is greatest during the first trimester; however, other serious developmental effects can occur with valproate use throughout pregnancy. the rate of congenital malformations among babies born to epileptic mothers who used valproate during pregnancy has been shown to be about four times higher than the rate among babies born to epileptic mothers who used other anti-seizure monotherapies [see warnings and precautions (5.2) and data (human)]. epidemiological studies have indicated that children exposed to valproate in utero have lower iq scores and a higher risk of neurodevelopmental disorders compared to children exposed to either another aed in utero or to no aeds in utero [see warnings and precautions (5.3)and data (human)]. an observational study has suggested that exposure to valproate products during pregnancy increases the risk of autism spectrum disorders [see data (human)] . in animal studies, valproate administration during pregnancy resulted in fetal structural malformations similar to those seen in humans and neurobehavioral deficits in the offspring at clinically relevant doses [see data (animal)] . there have been reports of hypoglycemia in neonates and fatal cases of hepatic failure in infants following maternal use of valproate during pregnancy. pregnant women taking valproate may develop hepatic failure or clotting abnormalities including thrombocytopenia, hypofibrinogenemia, and/or decrease in other coagulation factors, which may result in hemorrhagic complications in the neonate including death [see warnings and precautions (5.1, 5.8)]. available prenatal diagnostic testing to detect neural tube and other defects should be offered to pregnant women using valproate. evidence suggests that folic acid supplementation prior to conception and during the first trimester of pregnancy decreases the risk for congenital neural tube defects in the general population. it is not known whether the risk of neural tube defects or decreased iq in the offspring of women receiving valproate is reduced by folic acid supplementation. dietary folic acid supplementation both prior to conception and during pregnancy should be routinely recommended for patients using valproate [see warnings and precautions (5.2, 5.4)]. all pregnancies have a background risk of birth defect, loss, or other adverse outcomes. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. clinical considerations disease-associated maternal and/or embryo/fetal risk to prevent major seizures, women with epilepsy should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life. even minor seizures may pose some hazard to the developing embryo or fetus [see warnings and precautions (5.4)]. however, discontinuation of the drug may be considered prior to and during pregnancy in individual cases if the seizure disorder severity and frequency do not pose a serious threat to the patient. maternal adverse reactions pregnant women taking valproate may develop clotting abnormalities including thrombocytopenia, hypofibrinogenemia, and/or decrease in other coagulation factors, which may result in hemorrhagic complications in the neonate including death [see warnings and precautions (5.8)]. if valproate is used in pregnancy, the clotting parameters should be monitored carefully in the mother. if abnormal in the mother, then these parameters should also be monitored in the neonate. patients taking valproate may develop hepatic failure [see boxed warning and warnings and precautions (5.1)]. fatal cases of hepatic failure in infants exposed to valproate in utero have also been reported following maternal use of valproate during pregnancy. hypoglycemia has been reported in neonates whose mothers have taken valproate during pregnancy. data human neural tube defects and other structural abnormalities there is an extensive body of evidence demonstrating that exposure to valproate in utero increases the risk of neural tube defects and other structural abnormalities. based on published data from the cdc’s national birth defects prevention network, the risk of spina bifida in the general population is about 0.06 to 0.07% (6 to 7 in 10,000 births) compared to the risk following in utero valproate exposure estimated to be approximately 1 to 2% (100 to 200 in 10,000 births). the naaed pregnancy registry has reported a major malformation rate of 9 to 11% in the offspring of women exposed to an average of 1,000 mg/day of valproate monotherapy during pregnancy. these data show an up to a five-fold increased risk for any major malformation following valproate exposure in utero compared to the risk following exposure in utero to other aeds taken as monotherapy. the major congenital malformations included cases of neural tube defects, cardiovascular malformations, craniofacial defects (e.g., oral clefts, craniosynostosis), hypospadias, limb malformations (e.g., clubfoot, polydactyly), and other malformations of varying severity involving other body systems [see warnings and precautions (5.2)]. effect on iq and neurodevelopmental effects published epidemiological studies have indicated that children exposed to valproate in utero have lower iq scores than children exposed to either another aed in utero or to no aeds in utero . the largest of these studies 1 is a prospective cohort study conducted in the united states and united kingdom that found that children with prenatal exposure to valproate (n=62) had lower iq scores at age 6 (97 [95% c.i. 94 to 101]) than children with prenatal exposure to the other anti-epileptic drug monotherapy treatments evaluated: lamotrigine (108 [95% c.i. 105 to 110]), carbamazepine (105 [95% c.i. 102 to 108]) and phenytoin (108 [95% c.i. 104 to 112]). it is not known when during pregnancy cognitive effects in valproate-exposed children occur. because the women in this study were exposed to aeds throughout pregnancy, whether the risk for decreased iq was related to a particular time period during pregnancy could not be assessed [see warnings and precautions (5.3)]. although the available studies have methodological limitations, the weight of the evidence supports a causal association between valproate exposure in utero and subsequent adverse effects on neurodevelopment, including increases in autism spectrum disorders and attention deficit/hyperactivity disorder (adhd). an observational study has suggested that exposure to valproate products during pregnancy increases the risk of autism spectrum disorders. in this study, children born to mothers who had used valproate products during pregnancy had 2.9 times the risk (95% confidence interval [ci]: 1.7 to 4.9) of developing autism spectrum disorders compared to children born to mothers not exposed to valproate products during pregnancy. the absolute risks for autism spectrum disorders were 4.4% (95% ci: 2.6% to 7.5%) in valproate-exposed children and 1.5% (95% ci: 1.5% to 1.6%) in children not exposed to valproate products. another observational study found that children who were exposed to valproate in utero had an increased risk of adhd (adjusted hr 1.48; 95% ci, 1.09 to 2.00) compared with the unexposed children. because these studies were observational in nature, conclusions regarding a causal association between in utero valproate exposure and an increased risk of autism spectrum disorder and adhd cannot be considered definitive. other there are published case reports of fatal hepatic failure in offspring of women who used valproate during pregnancy. animal in developmental toxicity studies conducted in mice, rats, rabbits, and monkeys, increased rates of fetal structural abnormalities, intrauterine growth retardation, and embryo-fetal death occurred following administration of valproate to pregnant animals during organogenesis at clinically relevant doses (calculated on a body surface area [mg/m 2 ] basis). valproate induced malformations of multiple organ systems, including skeletal, cardiac, and urogenital defects. in mice, in addition to other malformations, fetal neural tube defects have been reported following valproate administration during critical periods of organogenesis, and the teratogenic response correlated with peak maternal drug levels. behavioral abnormalities (including cognitive, locomotor, and social interaction deficits) and brain histopathological changes have also been reported in mice and rat offspring exposed prenatally to clinically relevant doses of valproate. risk summary valproate is excreted in human milk. data in the published literature describe the presence of valproate in human milk (range: 0.4 mcg/ml to 3.9 mcg/ml), corresponding to 1% to 10% of maternal serum levels. valproate serum concentrations collected from breastfed infants aged 3 days postnatal to 12 weeks following delivery ranged from 0.7 mcg/ml to 4 mcg/ml, which were 1% to 6% of maternal serum valproate levels. a published study in children up to six years of age did not report adverse developmental or cognitive effects following exposure to valproate via breast milk [see data (human)] . there are no data to assess the effects of divalproex sodium delayed-release tablets on milk production or excretion. clinical considerations the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for divalproex sodium delayed-release tablets and any potential adverse effects on the breastfed infant from divalproex sodium delayed-release tablets or from the underlying maternal condition. monitor the breastfed infant for signs of liver damage including jaundice and unusual bruising or bleeding. there have been reports of hepatic failure and clotting abnormalities in offspring of women who used valproate during pregnancy [see use in specific populations (8.1)]. data human in a published study, breast milk and maternal blood samples were obtained from 11 epilepsy patients taking valproate at doses ranging from 300 mg/day to 2,400 mg/day on postnatal days 3 to 6. in 4 patients who were taking valproate only, breast milk contained an average valproate concentration of 1.8 mcg/ml (range: 1.1 mcg/ml to 2.2 mcg/ml), which corresponded to 4.8% of the maternal plasma concentration (range: 2.7% to 7.4%). across all patients (7 of whom were taking other aeds concomitantly), similar results were obtained for breast milk concentration (1.8 mcg/ml, range: 0.4 mcg/ml to 3.9 mcg/ml) and maternal plasma ratio (5.1%, range: 1.3% to 9.6%). a published study of 6 breastfeeding mother-infant pairs measured serum valproate levels during maternal treatment for bipolar disorder (750 mg/day or 1,000 mg/day). none of the mothers received valproate during pregnancy, and infants were aged from 4 weeks to 19 weeks at the time of evaluation. infant serum levels ranged from 0.7 mcg/ml to 1.5 mcg/ml. with maternal serum valproate levels near or within the therapeutic range, infant exposure was 0.9% to 2.3% of maternal levels. similarly, in 2 published case reports with maternal doses of 500 mg/day or 750 mg/day during breastfeeding of infants aged 3 months and 1 month, infant exposure was 1.5% and 6% that of the mother, respectively. a prospective observational multicenter study evaluated the long-term neurodevelopmental effects of aed use on children. pregnant women receiving monotherapy for epilepsy were enrolled with assessments of their children at ages 3 years and 6 years. mothers continued aed therapy during the breastfeeding period. adjusted iqs measured at 3 years for breastfed and non-breastfed children were 93 (n=11) and 90 (n=24), respectively. at 6 years, the scores for breastfed and non-breastfed children were 106 (n=11) and 94 (n=25), respectively (p=0.04). for other cognitive domains evaluated at 6 years, no adverse cognitive effects of continued exposure to an aed (including valproate) via breast milk were observed. contraception women of childbearing potential should use effective contraception while taking valproate [see boxed warning, warnings and precautions (5.4), drug interactions (7), and use in specific populations (8.1)]. this is especially important when valproate use is considered for a condition not usually associated with permanent injury or death such as prophylaxis of migraine headaches [see contraindications (4)]. infertility there have been reports of male infertility coincident with valproate therapy [see adverse reactions (6.4)]. in animal studies, oral administration of valproate at clinically relevant doses resulted in adverse reproductive effects in males [see nonclinical toxicology (13.1)]. experience has indicated that pediatric patients under the age of two years are at a considerably increased risk of developing fatal hepatotoxicity, especially those with the aforementioned conditions [see boxed warning and warnings and precautions (5.1)]. when divalproex sodium delayed-release tablets are used in this patient group, it should be used with extreme caution and as a sole agent. the benefits of therapy should be weighed against the risks. above the age of 2 years, experience in epilepsy has indicated that the incidence of fatal hepatotoxicity decreases considerably in progressively older patient groups. younger children, especially those receiving enzyme-inducing drugs, will require larger maintenance doses to attain targeted total and unbound valproate concentrations. pediatric patients (i.e., between 3 months and 10 years) have 50% higher clearances expressed on weight (i.e., ml/min/kg) than do adults. over the age of 10 years, children have pharmacokinetic parameters that approximate those of adults. the variability in free fraction limits the clinical usefulness of monitoring total serum valproic acid concentrations. interpretation of valproic acid concentrations in children should include consideration of factors that affect hepatic metabolism and protein binding. pediatric clinical trials divalproex sodium was studied in seven pediatric clinical trials. two of the pediatric studies were double-blinded placebo-controlled trials to evaluate the efficacy of divalproex sodium er for the indications of mania (150 patients aged 10 to 17 years, 76 of whom were on divalproex sodium er) and migraine (304 patients aged 12 to 17 years, 231 of whom were on divalproex sodium er). efficacy was not established for either the treatment of migraine or the treatment of mania. the most common drug-related adverse reactions (reported >5% and twice the rate of placebo) reported in the controlled pediatric mania study were nausea, upper abdominal pain, somnolence, increased ammonia, gastritis and rash. the remaining five trials were long term safety studies. two six-month pediatric studies were conducted to evaluate the long-term safety of divalproex sodium er for the indication of mania (292 patients aged 10 to 17 years). two twelve-month pediatric studies were conducted to evaluate the long-term safety of divalproex sodium er for the indication of migraine (353 patients aged 12 to 17 years). one twelve-month study was conducted to evaluate the safety of divalproex sodium sprinkle capsules in the indication of partial seizures (169 patients aged 3 to 10 years). in these seven clinical trials, the safety and tolerability of divalproex sodium in pediatric patients were shown to be comparable to those in adults [see adverse reactions (6)]. juvenile animal toxicology in studies of valproate in immature animals, toxic effects not observed in adult animals included retinal dysplasia in rats treated during the neonatal period (from postnatal day 4) and nephrotoxicity in rats treated during the neonatal and juvenile (from postnatal day 14) periods. the no-effect dose for these findings was less than the maximum recommended human dose on a mg/m 2 basis. no patients above the age of 65 years were enrolled in double-blind prospective clinical trials of mania associated with bipolar illness. in a case review study of 583 patients, 72 patients (12%) were greater than 65 years of age. a higher percentage of patients above 65 years of age reported accidental injury, infection, pain, somnolence, and tremor. discontinuation of valproate was occasionally associated with the latter two events. it is not clear whether these events indicate additional risk or whether they result from preexisting medical illness and concomitant medication use among these patients. a study of elderly patients with dementia revealed drug related somnolence and discontinuation for somnolence [see warnings and precautions (5.14)]. the starting dose should be reduced in these patients, and dosage reductions or discontinuation should be considered in patients with excessive somnolence [see dosage and administration (2.4)]. there is insufficient information available to discern the safety and effectiveness of valproate for the prophylaxis of migraines in patients over 65.

severe enough to require an opioid analgesic and for which alternative treatments are inadequate. limitations of use because of the risks of addiction, abuse, and misuse with opioids, which can occur at any dosage or duration [see warnings and precautions (5.1)] , reserve oxaydo for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or opioid combination products): - have not been tolerated or are not expected to be tolerated, - have not provided adequate analgesia or are not expected to provide adequate analgesia. oxaydo should not be used for an extended period of time unless the pain remains severe enough to require an opioid analgesic and for which alternative treatment options continue to be inadequate. oxaydo is contraindicated in patients with: - significant respiratory depression [see warnings and precautions (5.2)] - acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment [see warnings and precautions (5.8)] - known or suspected gastrointestinal obstruction, including paralytic ileus [see warnings and precautions (5.12)] - hypersensitivity to oxycodone, oxycodone salts, or any components of the product (e.g., anaphylaxis) [see adverse reactions (6.2)] risk summary use of opioid analgesics for an extended period of time during pregnancy may cause neonatal opioid withdrawal syndrome [see warnings and precautions (5.4)] . there are no available data with oxaydo in pregnant women to inform a drug-associated risk for major birth defects and miscarriage. in animal reproduction studies with oral administrations of oxycodone hcl in rats and rabbits during the period of organogenesis at doses 2.6 and 8.1 times, respectively, the human dose of 60 mg/day did not reveal evidence of teratogenicity or embryo-fetal toxicity. in several published studies, treatment of pregnant rats with oxycodone at clinically relevant doses and below resulted in neurobehavioral effects in offspring [see data] . based on animal data, advise pregnant women of the potential risk to a fetus. the 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 use of opioid analgesics for an extended period of time during pregnancy for medical or nonmedical purposes can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth. neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea, and failure to gain weight. the onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn. observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly  [see warnings and precautions (5.4)] .       labor or delivery opioids cross the placenta and may produce respiratory depression and psycho-physiologic effects in neonates. an opioid antagonist, such as naloxone, must be available for reversal of opioid-induced respiratory depression in the neonate. oxaydo is not recommended for use in pregnant women during or immediately prior to labor, when other analgesic techniques are more appropriate. opioid analgesics, including oxaydo, can prolong labor through actions which temporarily reduce the strength, duration, and frequency of uterine contractions. however, this effect is not consistent and may be offset by an increased rate of cervical dilation, which tends to shorten labor. monitor neonates exposed to opioid analgesics during labor for signs of excess sedation and respiratory depression. data       animal data in embryo-fetal development studies in rats and rabbits, pregnant animals received oral doses of oxycodone hcl administered during the period of organogenesis up to 16 mg/kg/day and up 25 mg/kg/day, respectively. these studies revealed no evidence of teratogenicity or embryo-fetal toxicity due to oxycodone. the highest doses tested in rats and rabbits were equivalent to approximately 2.6 and 8.1 times an adult human dose of 60 mg/day, respectively, on a mg/m2 basis. in published studies, offspring of pregnant rats administered oxycodone during gestation have been reported to exhibit neurobehavioral effects including altered stress responses, increased anxiety-like behavior (2 mg/kg/day iv from gestation day 8 to 21 and postnatal day 1, 3, and 5; 0.3-times an adult human dose of 60 mg/day, on a mg/m2 basis) and altered learning and memory (15 mg/kg/day orally from breeding through parturition; 2.4 times an adult human dose of 60 mg/day, on a mg/m2 basis). risk summary available data from lactation studies indicate that oxycodone is present in breastmilk and that doses of less than 60 mg/day of the immediate-release formulation are unlikely to result in clinically relevant exposures in breastfed infants. a pharmacokinetics study utilizing opportunistic sampling of 76 lactating women receiving oxycodone immediate-release products for postpartum pain management showed that oxycodone concentrates in breastmilk with an average milk to plasma ratio of 3.2. the relative infant dose was low, approximately 1.3% of a weight-adjusted maternal dose (see data). in the same study, among the 70 infants exposed to oxycodone in breastmilk, no adverse events were attributed to oxycodone. however, based on known adverse effects in adults, infants should be monitored for signs of excess sedation and respiratory depression (see clinical considerations). there are no data on the effects of the oxycodone on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for oxaydo and any potential adverse effects on the breastfed infant from oxaydo or from the underlying maternal condition. clinical considerations monitor infants exposed to oxaydo through breast milk for excess sedation and respiratory depression. withdrawal symptoms can occur in breastfed infants when maternal administration of an opioid analgesic is stopped or when breastfeeding is stopped. data oxycodone concentration data from 76 lactating women receiving immediate-release oxycodone products for postpartum pain management, and 28 infants exposed to oxycodone in breastmilk showed that following a median (range) dose of oxycodone in mothers of 9.2 (5-10) mg/dose or 33.0 (5.4-59.3) mg/day, oxycodone concentrated in breastmilk with a median (range) milk to plasma ratio of 3.2 (1.2-5.3). however, when using maternal breastmilk data to estimate the daily and relative infant dose, the infant dose was 0.006 mg/kg/day, which is 1.3% of a weight-adjusted maternal dose of 10 mg every 6 hours. these estimates based on maternal breastmilk concentrations were corroborated by the observed infant concentrations, of which over 75% (19/25) were below the limit of quantification. among the 6 infants with quantifiable concentration, the median (range) concentration was 0.2 ng/ml (0.1-0.7). these concentrations are 100 to 1000 times lower than concentrations observed in other studies after infants received oxycodone at 0.1 mg/kg/dose (~20-200 ng/ml). infertility use of opioids for an extended period of time 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)] . the safety, effectiveness, and pharmacokinetics of oxaydo in pediatric patients below the age of 18 have not been established. elderly patients (aged 65 years or older) may have increased sensitivity to oxycodone. in general, use caution when selecting a dosage for an elderly patient, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy. respiratory depression is the chief risk for elderly patients treated with opioids and has occurred after large initial doses were administered to patients who were not opioid-tolerant or when opioids were co-administered with other agents that depress respiration. titrate the dosage of oxaydo slowly in geriatric patients frequently reevaluate the patient for signs of central nervous system and respiratory depression [see warnings and precautions (5.2)] . oxycodone is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to regularly evaluate renal function. since oxycodone is extensively metabolized in the liver, its clearance may decrease in patients with hepatic impairment. follow a conservative approach to initiate dosing in patients with hepatic impairment. regularly evaluate patients and adjust the dose based on clinical response [see dosage and administration (2.2)] . information from oxycodone hcl indicates that patients with renal impairment had higher plasma concentrations of oxycodone than subjects with normal renal function. use a conservative approach to initiate dosing in patients with renal impairment. regularly evaluate patients and adjust the dose based on clinical response [see dosage and administration (2.2)] . oxaydo contains oxycodone, a schedule ii controlled substance. oxaydo contains oxycodone, a substance with high potential for misuse and abuse, which can lead to the development of substance use disorder, including addiction [see warnings and precautions (5.1)] . misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a healthcare provider or for whom it was not prescribed. abuse is the intentional, non-therapeutic use of a prescription drug, even once, for its desirable psychological or physiological effects. drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence.  misuse and abuse of oxaydo increases risk of overdose, which may lead to central nervous system and respiratory depression, hypotension, seizures, and death. the risk is increased with concurrent abuse of oxaydo with alcohol and/or other cns depressants. abuse of and addiction to opioids in some individuals may not be accompanied by concurrent tolerance and symptoms of physical dependence. in addition, abuse of opioids can occur in the absence of addiction. all patients treated with opioids require careful and frequent reevaluation for signs of misuse, abuse, and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use. patients at high risk of oxaydo abuse include those with a history of prolonged use of any opioid, including products containing oxycodone, those with a history of drug or alcohol abuse, or those who use oxaydo in combination with other abused drugs. “drug-seeking” behavior is very common in persons with substance use disorders. drug-seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing, or referral, repeated “loss” of prescriptions, tampering with prescriptions, and reluctance to provide prior medical records or contact information for other treating healthcare provider(s). “doctor shopping” (visiting multiple prescribers to obtain additional prescriptions) is common among people who abuse drugs and people with substance use disorder. preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with inadequate pain control. oxaydo, like other opioids, can be diverted for nonmedical use into illicit channels of distribution. careful record-keeping of prescribing information, including quantity, frequency, and renewal requests, as required by state and federal law, is strongly advised. proper assessment of the patient, proper prescribing practices, periodic reevaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs. risks specific to abuse of oxaydo abuse of oxaydo poses a risk of overdose and death. the risk is increased with concurrent use of oxaydo with alcohol and/or other cns depressants.  oxaydo is intended for oral use only.  parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and hiv.   in a double-blind, active-comparator, crossover study in 40 non-dependent recreational opioid users, “drug liking” responses and single-dose safety of crushed oxaydo tablets were compared with crushed immediate-release oxycodone tablets when subjects self-administered the drug intranasally. the presence of sequence effects resulted in questionable reliability of the second period data. first period data demonstrated small numeric differences in the median and mean drug liking scores, lower in response to oxaydo than immediate-release oxycodone. thirty percent of subjects exposed to oxaydo responded that they would not take the drug again compared to 5% of subjects exposed to immediate-release oxycodone. study subjects self-administering oxaydo reported a higher incidence of nasopharyngeal and facial adverse events and a decreased ability to completely insufflate two crushed tablets within a fixed time period (21 of 40 subjects). the clinical significance of the difference in drug liking and difference in response to taking the drug again reported in this study has not yet been established. there is no evidence that oxaydo has a reduced abuse liability compared to immediate-release oxycodone. both tolerance and physical dependence can develop during use of opioid therapy. tolerance is a physiological state characterized by a reduced response to a drug after repeated administration (i.e., a higher dose of a drug is required to produce the same effect that was once obtained at a lower dose). physical dependence is a state that develops as a result of a physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt discontinuation or a significant dose reduction of a drug. withdrawal may be precipitated through the administration of drugs with opioid antagonist activity (e.g., naloxone), mixed agonist/antagonist analgesics (e.g., pentazocine, butorphanol, nalbuphine), or partial agonists (e.g., buprenorphine). physical dependence may not occur to a clinically significant degree until after several days to weeks of continued use. do not abruptly discontinue oxaydo in a patient physically dependent on opioids. rapid tapering of oxaydo in a patient physically dependent on opioids may lead to serious withdrawal symptoms, uncontrolled pain, and suicide. rapid discontinuation has also been associated with attempts to find other sources of opioid analgesics, which may be confused with drug-seeking for abuse. when discontinuing oxaydo, gradually taper the dosage using a patient-specific plan that considers the following: the dose of oxaydo the patient has been taking, the duration of treatment, and the physical and psychological attributes of the patient. to improve the likelihood of a successful taper and minimize withdrawal symptoms, it is important that the opioid tapering schedule is agreed upon by the patient. in patients taking opioids for an extended period of time at high doses, ensure that a multimodal approach to pain management, including mental health support (if needed), is in place prior to initiating an opioid analgesic taper [see dosage and administration (2.5), and warnings and precautions (5.14) ]. infants born to mothers physically dependent on opioids will also be physically dependent and may exhibit respiratory difficulties and withdrawal signs [see use in specific populations (8.1)] .

cardinal health 107, llc - mirtazapine (unii: a051q2099q) (mirtazapine - unii:a051q2099q) - mirtazapine 15 mg - mirtazapine tablets are indicated for the treatment of major depressive disorder (mdd) in adults [see clinical studies (14)] . mirtazapine tablets are contraindicated in patients: 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-research-programs/pregnancyregistry/antidepressants/. prolonged experience with mirtazapine in pregnant women, based on published observational studies and postmarketing reports, has not reliably identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. there are risks associated with untreated depression in pregnancy (see clinical considerations) . in animal reproduction studies, oral administration of mirtazapine to pregnant rats and rabbits during the period of organogenesis revealed no evidence of teratogenic effects up to 20 and 17 times the maximum recommended human dose (mrhd) of 45 mg, respectively, based on mg/m2 body surface area. however, in rats, there was an increase in postimplantation loss at 20 times the mrhd based on mg/m2 body surface area. oral administration of mirtazapine to pregnant rats during pregnancy and lactation resulted in an increase in pup deaths and a decrease in pup birth weights at doses 20 times the mrhd based on mg/m2 body surface area (see data) . 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. women who discontinue antidepressants during pregnancy are more likely to experience a relapse of major depression than women who continue antidepressants. this finding is from a prospective, longitudinal study that followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum. mirtazapine was administered orally to pregnant rats and rabbits during the period of organogenesis at doses of 2.5, 15, and 100 mg/kg/day and 2.5, 10, and 40 mg/kg/day, respectively, which are up to 20 and 17 times the maximum recommended human dose (mrhd) of 45 mg based on mg/m2 body surface area, respectively. no evidence of teratogenic effects was observed. however, in rats, there was an increase in postimplantation loss in dams treated with mirtazapine at 100 mg/kg/day which is 20 times the mrhd based on mg/m2 body surface area. oral administration of mirtazapine at doses of 2.5, 15, and 100 mg/kg/day to pregnant rats during pregnancy and lactation resulted in an increase in pup deaths during the first 3 days of lactation and a decrease in pup birth weights at 20 times the mrhd based on mg/mg2 body surface area. the cause of these deaths is not known. the no effect dose level is 3 times the mrhd based on mg/m2 body surface area. data from published literature report the presence of mirtazapine in human milk at low levels with relative infant doses for mirtazapine ranging between 0.6 and 2.8% of the maternal weight-adjusted dose (see data) . no adverse effects on the breastfed infant have been reported in most cases of maternal use of mirtazapine. there are no data on the effects of mirtazapine on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for mirtazapine and any potential adverse effects on the breastfed infant from mirtazapine or from the underlying maternal condition. in a published pooled analysis of 8 breastfeeding mother-infant pairs, the mean (min, max) total relative infant doses for mirtazapine and its desmethyl metabolite were 1.5% (0.6%, 2.8%) and 0.4% (0.1%, 0.7%) of the maternal weight-adjusted dose (median (min, max) dose of 38 mg (30 mg, 120 mg), respectively). no adverse drug effects were reported for any of the infants. the safety and effectiveness of mirtazapine tablets have not been established in pediatric patients with mdd. two placebo-controlled trials in 258 pediatric patients with mdd have been conducted with mirtazapine, and the data were insufficient to establish the safety and effectiveness of mirtazapine tablets in pediatric patients with mdd. antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see boxed warning and warnings and precautions (5.1)] . in an 8-week-long clinical trial in pediatric patients receiving doses between 15 to 45 mg per day, 49% of mirtazapine-treated patients had a weight gain of at least 7%, compared to 5.7% of placebo-treated patients. the mean increase in weight was 4 kg (2 kg sd) for mirtazapine-treated patients versus 1 kg (2 kg sd) for placebo-treated patients [see warnings and precautions (5.7)] . approximately 190 patients ≥ 65 years of age participated in clinical studies with mirtazapine. mirtazapine tablets are known to be substantially excreted by the kidney (75%), and the risk of decreased clearance of this drug is greater in patients with impaired renal function. pharmacokinetic studies revealed a decreased clearance of mirtazapine in the elderly [see clinical pharmacology (12.3)] . sedating drugs, including mirtazapine tablets, may cause confusion and over-sedation in the elderly. elderly patients may be at greater risk of developing hyponatremia. caution is indicated when administering mirtazapine tablets to elderly patients [see warnings and precautions (5.12), (5.15) and clinical pharmacology (12.3)] . in general, dose selection for an elderly patient should be conservative, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. the clearance of mirtazapine is reduced in patients with moderate to severe renal or hepatic impairment. consequently, plasma mirtazapine levels may be increased in these patient groups, compared to levels observed in patients without renal or hepatic impairment. dosage decrease may be necessary when administering mirtazapine tablets to patients with moderate to severe renal or hepatic impairment [see warnings and precautions (5.13), use in specific populations (8.5), and clinical pharmacology (12.3)] .

specgx llc - buprenorphine hydrochloride (unii: 56w8mw3en1) (buprenorphine - unii:40d3scr4gz), naloxone hydrochloride dihydrate (unii: 5q187997ee) (naloxone - unii:36b82amq7n) - buprenorphine 2 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 postnatal 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 (10.0 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/m2 ) 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 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 (cavg ) 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 (byoo-pre-nor-feen) and naloxone (nah-lox-own) sublingual tablets usp, ciii this
