bryant ranch prepack - methadone hydrochloride (unii: 229809935b) (methadone - unii:uc6vbe7v1z) - methadone hydrochloride tablets are indicated for the: 1. management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. limitations of use - because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with long-acting opioids [see warnings and precautions (5.1)] , reserve methadone hydrochloride tablets for use in patients for whom alternative analgesic treatment options (e.g., non-opioid analgesics or immediate-release opioid analgesics) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. - methadone hydrochloride tablets are not indicated as an as-needed (prn) analgesic. 2.  detoxification treatment of opioid addiction (heroin or other morphine-like drugs). 3. maintenance treatment of opioid addiction (heroin or other morphine-like drugs), in conjunction with appropriate social and medical services . limitations of use methadone products used for the treatment of opioid addiction in detoxification or maintenance programs are subject to the conditions for distribution and use required under 42 cfr 8.12 [see dosage and administration (2.1)] . methadone hydrochloride tablets are contraindicated in patients with: - significant respiratory depression [see warnings and precautions (5.3)]. - 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 (5.13)]. - hypersensitivity (e.g., anaphylaxis) to methadone [see adverse reactions (6)]. risk summary the majority of available data from clinical trials, observational studies, case series, and case reports on methadone use in pregnancy do not indicate an increased risk of major malformations specifically due to methadone. pregnant women involved in methadone maintenance programs have been reported to have improved prenatal care leading to reduced incidence of obstetric and fetal complications and neonatal morbidity and mortality when compared to women using illicit drugs. several factors, including maternal use of illicit drugs, nutrition, infection and psychosocial circumstances, complicate the interpretation of investigations of the children of women who take methadone during pregnancy. information is limited regarding dose and duration of methadone use during pregnancy, and most maternal exposure in these studies appears to occur after the first trimester of pregnancy (see data ). neonatal opioid withdrawal syndrome (nows) is an expected and treatable outcome of prolonged use of opioids during pregnancy [see warnings and  precautions (5.6)]. in published animal reproduction studies, methadone administered subcutaneously during the early gestational period produced neural tube defects (i.e., exencephaly and cranioschisis) in the hamster at doses 2 times the human daily oral dose of 120 mg/day on a mg/m2 basis (hdd) and in mice at doses equivalent to the hdd. administration of methadone to pregnant animals during organogenesis and through lactation resulted decreased litter size, increased pup mortality, decreased pup body weights, developmental delays, and long-term neurochemical changes in the brain of offspring which correlate with altered behavioral responses that persist through adulthood at exposures comparable to and less than the hdd. administration of methadone to male rodents prior to mating with untreated females resulted in increased neonatal mortality and significant differences in behavioral tests in the offspring at exposures comparable to and less than the hdd (see data ). based on animal data, advise pregnant women of the potential risk to a fetus. 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 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. dosage adjustment during pregnancy : dosage adjustment using higher doses or administering the daily dose in divided doses may be necessary in pregnant women treated with methadone hydrochloride tablets. pregnant women appear to have significantly lower trough plasma methadone concentrations, increased plasma methadone clearance, and shorter methadone half-life than after delivery [see  dosage and administration (2.9) and clinical pharmacology (12.3)] . withdrawal signs and symptoms should be closely monitored 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 methadone hydrochloride 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 ( 5.6) ]. labor or delivery : opioid-dependent women on methadone maintenance therapy may require additional analgesia during labor. monitor neonates exposed to opioid analgesics during labor for signs of excess sedation and respiratory depression. data human data : the majority of available data from clinical trials, observational studies, case series, and case reports on methadone use in pregnancy do not indicate an increased risk of major malformations specifically due to methadone. findings regarding specific major malformations, decreased fetal growth, premature birth and sudden infant death syndrome have been inconsistent. children prenatally exposed to methadone have been reported to demonstrate mild but persistent deficits in performance on psychometric and behavioral tests and visual abnormalities. 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 methadone-treated and buprenorphine-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 methadone and buprenorphine groups, the study findings are difficult to interpret. animal data : formal reproductive and developmental toxicology studies for methadone have not been conducted. exposure margins for the following published study reports are based on a human daily dose (hdd) of 120 mg methadone using a body surface area comparison. in a published study in pregnant hamsters, a single subcutaneous dose of methadone ranging from 31 mg/kg (2 times the hdd) to 185 mg/kg on gestation day 8 resulted in a decrease in the number of fetuses per litter and an increase in the percentage of fetuses exhibiting neural tube defects including exencephaly, cranioschisis, and “various other lesions.” the majority of the doses tested also resulted in maternal death. in a study in pregnant jbt/jd mice, a single subcutaneous dose of 22 to 24 mg/kg methadone (approximately equivalent to the hdd) administered on gestation day 9 produced exencephaly in 11% of the embryos. in another study in pregnant mice, subcutaneous doses up to 28 mg/kg/day methadone (equivalent to the hdd) administered from gestation day 6 to 15 resulted in no malformations, but there were increased post-implantation loss and decreased live fetuses at 10 mg/kg/day or greater (0.4 times the hdd) and decreased ossification and fetal body weight at 20 mg/kg/day or greater (0.8 times the hdd). in a second study of pregnant mice dosed with subcutaneous doses up to 28 mg/kg/day methadone from gestation day 6 to 15, there was decreased pup viability, delayed onset of development of negative phototaxis and eye opening, increased righting reflexes at 5 mg/kg/day or greater (0.2 times the hdd), and decreased number of live pups at birth and decreased pup weight gain at 20 mg/kg/day or greater (0.8 times the hdd). no effects were reported in a study of pregnant rats and rabbits at oral doses up to 40 mg/kg (3 and 6 times, respectively, the hdd) administered from gestation days 6 to 15 and 6 to 18, respectively. when pregnant rats were treated with intraperitoneal doses of 2.5, 5, or 7.5 mg/kg methadone from one week prior to mating, through gestation until the end of lactation period, 5 mg/kg or greater (0.4 times the hdd) methadone resulted in decreases in litter size and live pups born and 7.5 mg/kg (0.6 times the hdd) resulted in decreased birth weights. furthermore, decreased pup viability and pup body weight gain at 2.5 mg/kg or greater (0.2 times the hdd) were noted during the preweaning period. additional animal data demonstrate evidence for neurochemical changes in the brains of offspring from methadone-treated pregnant rats, including changes to the cholinergic, dopaminergic, noradrenergic and serotonergic systems at doses below the hdd. other animal studies have reported that prenatal and/or postnatal exposure to opioids including methadone alters neuronal development and behavior in the offspring including alterations in learning ability, motor activity, thermal regulation, nociceptive responses, and sensitivity to drugs at doses below the hdd. treatment of pregnant rats subcutaneously with 5 mg/kg methadone from gestation day 14 to 19 (0.4 times the hdd) reduced fetal blood testosterone and androstenedione in males. published animal data have reported increased neonatal mortality in the offspring of male rodents that were treated with methadone at doses comparable to and less than the hdd for 1 to 12 days before and/or during mating (with more pronounced effects in the first 4 days). in these studies, the female rodents were not treated with methadone, indicating paternally-mediated developmental toxicity. specifically, methadone administered to the male rat prior to mating with methadone-naïve females resulted in decreased weight gain in progeny after weaning. the male progeny demonstrated reduced thymus weights, whereas the female progeny demonstrated increased adrenal weights. behavioral testing of these male and female progeny revealed significant differences in behavioral tests compared to control animals, suggesting that paternal methadone exposure can produce physiological and behavioral changes in progeny in this model. examination of uterine contents of methadone-naïve female mice bred to methadone-treated male mice (once a day for three consecutive days) indicated that methadone treatment produced an increase in the rate of preimplantation deaths in all post-meiotic states at 1 mg/kg/day or greater (0.04 times the hdd). chromosome analysis revealed a dose-dependent increase in the frequency of chromosomal abnormalities at 1 mg/kg/day or greater. studies demonstrated that methadone treatment of male rats for 21 to 32 days prior to mating with methadone-naïve females did not produce any adverse effects, suggesting that prolonged methadone treatment of the male rat resulted in tolerance to the developmental toxicities noted in the progeny. mechanistic studies in this rat model suggest that the developmental effects of “paternal” methadone on the progeny appear to be due to decreased testosterone production. these animal data mirror the reported clinical findings of decreased testosterone levels in human males on methadone maintenance therapy for opioid addiction and in males receiving chronic intraspinal opioids. risk summary based on two small clinical studies, methadone was present in low levels in human milk, but the exposed infants in these studies did not show adverse reactions. based on an average milk consumption of 150 ml/kg/day, an infant would consume approximately 17.4 mcg/kg/day which is approximately 2 to 3% of the oral maternal dose. there have been rare case reports of sedation and respiratory depression in infants exposed to methadone through breast milk (see  data ). monitor infants exposed to methadone hydrochloride through breastmilk for excess sedation and respiratory depression. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for methadone and any potential adverse effects on the breastfed child from the drug or from the underlying maternal condition. data in a study of ten breastfeeding women maintained on oral methadone doses of 10 to 80 mg/day, methadone concentrations from 50 to 570 mcg/l in milk were reported, which, in the majority of samples, were lower than maternal serum drug concentrations at steady state. peak methadone levels in milk occur approximately 4 to 5 hours after an oral dose. in a study of twelve breastfeeding women maintained on oral methadone doses of 20 to 80 mg/day, methadone concentrations from 39 to 232 mcg/l in milk were reported. based on an average milk consumption of 150 ml/kg/day, an infant would consume approximately 17.4 mcg/kg/day, which is approximately 2 to 3% of the oral maternal dose. methadone has been detected in very low plasma concentrations in some infants whose mothers were taking methadone. infertility the effect of methadone hydrochloride tablets on fertility is unknown. 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), clinical pharmacology (12.2), nonclinical pharmacology (13.1) ]. reproductive function in human males may be decreased by methadone treatment. reductions in ejaculate volume and seminal vesicle and prostate secretions have been reported in methadone-treated individuals. in addition, reductions in serum testosterone levels and sperm motility, and abnormalities in sperm morphology have been reported. in published animal studies, methadone produces a significant regression of sex accessory organs and testes of male mice and rats and administration of methadone to pregnant rats reduced fetal blood testosterone and androstenedione in male offspring [see nonclinical toxicology (13)]. the safety, effectiveness, and pharmacokinetics of methadone in pediatric patients below the age of 18 years have not been established. clinical studies of methadone did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently compared to younger subjects. other reported clinical experience has not identified differences in responses between elderly and younger patients. elderly patients (aged 65 years or older) may have increased sensitivity to methadone. 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 methadone hydrochloride tablets slowly in geriatric patients and monitor closely for signs of central nervous system and respiratory depression [see warnings and precautions (5.8)] . methadone is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. methadone pharmacokinetics have not been extensively evaluated in patients with hepatic insufficiency. methadone is metabolized by hepatic pathways; therefore, patients with liver impairment may be at risk of increased systemic exposure to methadone after multiple dosing. start these patients on lower doses and titrate slowly while carefully monitoring for signs of respiratory and central nervous system depression. methadone pharmacokinetics have not been extensively evaluated in patients with renal insufficiency. since unmetabolized methadone and its metabolites are excreted in urine to a variable degree, start these patients on lower doses and with longer dosing intervals and titrate slowly while carefully monitoring for signs of respiratory and central nervous system depression. methadone hydrochloride tablets contain methadone, a schedule ii controlled substance. methadone hydrochloride tablets contain methadone, a substance with a high potential for abuse similar to other opioids including fentanyl, hydrocodone, hydromorphone, morphine, oxycodone, oxymorphone, and tapentadol. methadone hydrochloride tablets can be abused and are subject to misuse, addiction, and criminal diversion [see warnings and precautions (5.1)]. all patients treated with opioids for pain management require careful monitoring for signs of abuse and addiction, since use of opioid analgesic products carries the risk of addiction even under appropriate medical use. prescription drug abuse is the intentional non-therapeutic use of a prescription drug, even once, for its rewarding psychological or physiological effects. drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes: a strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful consequences, a higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes a physical withdrawal. “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 drug abusers and people suffering from untreated addiction. preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with poor pain control. abuse and addiction are separate and distinct from physical dependence and tolerance. healthcare providers should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. in addition, abuse of opioids can occur in the absence of true addiction. methadone hydrochloride tablets, like other opioids, can be diverted for non-medical 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 and selection of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs. risks specific to abuse of methadone hydrochloride tablets abuse of methadone hydrochloride tablets poses a risk of overdose and death. this risk is increased with concurrent abuse of methadone and alcohol or other substances. methadone hydrochloride tablets are for oral use only and must not be injected. with intravenous abuse the inactive ingredients in methadone hydrochloride tablets can result in local tissue necrosis, infection, pulmonary granulomas, embolism and death, and increased risk of endocarditis and valvular heart injury. parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and hiv. both tolerance and physical dependence can develop during chronic opioid therapy. tolerance is the need for increasing doses of opioids to maintain a defined effect such as analgesia (in the absence of disease progression or other external factors). tolerance may occur to both the desired and undesired effects of drugs, and may develop at different rates for different effects. physical dependence is a physiological state in which the body adapts to the drug after a period of regular exposure, resulting in withdrawal symptoms after abrupt discontinuation or a significant dosage reduction of a drug. withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity (e.g., naloxone, nalmefene), 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 opioid usage. do not abruptly discontinue methadone hydrochloride tablets in a patient physically dependent on opioids. rapid tapering of methadone hydrochloride tablets 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 methadone hydrochloride tablets, gradually taper the dosage using a patient-specific plan that considers the following: the dose of methadone hydrochloride tablets 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 a long duration 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 (2.6), warnings (5.15)] . 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) ]. neonatal opioid withdrawal syndrome (nows) is an expected and treatable outcome of prolonged use of opioids during pregnancy [see warnings and precautions (5.5) ].

females resulted in increased neonatal mortality and significant differences in behavioral tests in the offspring at exposures comparable to and less than the hdd (see data ). based on animal data, advise pregnant women of the potential risk to a fetus. 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 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. dosage adjustment during pregnancy : dosage adjustment using higher doses or administering the daily dose in divided doses may be necessary in pregnant women treated with methadone hydrochloride tablets. pregnant women appear to have significantly lower trough plasma methadone concentrations, increased plasma methadone clearance, and shorter methadone half-life than after delivery [see  dosage and administration (2.9) and clinical pharmacology (12.3)] . withdrawal signs and symptoms should be closely monitored 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 methadone hydrochloride 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 ( 5.6) ]. labor or delivery : opioid-dependent women on methadone maintenance therapy may require additional analgesia during labor. monitor neonates exposed to opioid analgesics during labor for signs of excess sedation and respiratory depression. data human data : the majority of available data from clinical trials, observational studies, case series, and case reports on methadone use in pregnancy do not indicate an increased risk of major malformations specifically due to methadone. findings regarding specific major malformations, decreased fetal growth, premature birth and sudden infant death syndrome have been inconsistent. children prenatally exposed to methadone have been reported to demonstrate mild but persistent deficits in performance on psychometric and behavioral tests and visual abnormalities. 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 methadone-treated and buprenorphine-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 methadone and buprenorphine groups, the study findings are difficult to interpret. animal data : formal reproductive and developmental toxicology studies for methadone have not been conducted. exposure margins for the following published study reports are based on a human daily dose (hdd) of 120 mg methadone using a body surface area comparison. in a published study in pregnant hamsters, a single subcutaneous dose of methadone ranging from 31 mg/kg (2 times the hdd) to 185 mg/kg on gestation day 8 resulted in a decrease in the number of fetuses per litter and an increase in the percentage of fetuses exhibiting neural tube defects including exencephaly, cranioschisis, and “various other lesions.” the majority of the doses tested also resulted in maternal death. in a study in pregnant jbt/jd mice, a single subcutaneous dose of 22 to 24 mg/kg methadone (approximately equivalent to the hdd) administered on gestation day 9 produced exencephaly in 11% of the embryos. in another study in pregnant mice, subcutaneous doses up to 28 mg/kg/day methadone (equivalent to the hdd) administered from gestation day 6 to 15 resulted in no malformations, but there were increased post-implantation loss and decreased live fetuses at 10 mg/kg/day or greater (0.4 times the hdd) and decreased ossification and fetal body weight at 20 mg/kg/day or greater (0.8 times the hdd). in a second study of pregnant mice dosed with subcutaneous doses up to 28 mg/kg/day methadone from gestation day 6 to 15, there was decreased pup viability, delayed onset of development of negative phototaxis and eye opening, increased righting reflexes at 5 mg/kg/day or greater (0.2 times the hdd), and decreased number of live pups at birth and decreased pup weight gain at 20 mg/kg/day or greater (0.8 times the hdd). no effects were reported in a study of pregnant rats and rabbits at oral doses up to 40 mg/kg (3 and 6 times, respectively, the hdd) administered from gestation days 6 to 15 and 6 to 18, respectively. when pregnant rats were treated with intraperitoneal doses of 2.5, 5, or 7.5 mg/kg methadone from one week prior to mating, through gestation until the end of lactation period, 5 mg/kg or greater (0.4 times the hdd) methadone resulted in decreases in litter size and live pups born and 7.5 mg/kg (0.6 times the hdd) resulted in decreased birth weights. furthermore, decreased pup viability and pup body weight gain at 2.5 mg/kg or greater (0.2 times the hdd) were noted during the preweaning period. additional animal data demonstrate evidence for neurochemical changes in the brains of offspring from methadone-treated pregnant rats, including changes to the cholinergic, dopaminergic, noradrenergic and serotonergic systems at doses below the hdd. other animal studies have reported that prenatal and/or postnatal exposure to opioids including methadone alters neuronal development and behavior in the offspring including alterations in learning ability, motor activity, thermal regulation, nociceptive responses, and sensitivity to drugs at doses below the hdd. treatment of pregnant rats subcutaneously with 5 mg/kg methadone from gestation day 14 to 19 (0.4 times the hdd) reduced fetal blood testosterone and androstenedione in males. published animal data have reported increased neonatal mortality in the offspring of male rodents that were treated with methadone at doses comparable to and less than the hdd for 1 to 12 days before and/or during mating (with more pronounced effects in the first 4 days). in these studies, the female rodents were not treated with methadone, indicating paternally-mediated developmental toxicity. specifically, methadone administered to the male rat prior to mating with methadone-naïve females resulted in decreased weight gain in progeny after weaning. the male progeny demonstrated reduced thymus weights, whereas the female progeny demonstrated increased adrenal weights. behavioral testing of these male and female progeny revealed significant differences in behavioral tests compared to control animals, suggesting that paternal methadone exposure can produce physiological and behavioral changes in progeny in this model. examination of uterine contents of methadone-naïve female mice bred to methadone-treated male mice (once a day for three consecutive days) indicated that methadone treatment produced an increase in the rate of preimplantation deaths in all post-meiotic states at 1 mg/kg/day or greater (0.04 times the hdd). chromosome analysis revealed a dose-dependent increase in the frequency of chromosomal abnormalities at 1 mg/kg/day or greater. studies demonstrated that methadone treatment of male rats for 21 to 32 days prior to mating with methadone-naïve females did not produce any adverse effects, suggesting that prolonged methadone treatment of the male rat resulted in tolerance to the developmental toxicities noted in the progeny. mechanistic studies in this rat model suggest that the developmental effects of “paternal” methadone on the progeny appear to be due to decreased testosterone production. these animal data mirror the reported clinical findings of decreased testosterone levels in human males on methadone maintenance therapy for opioid addiction and in males receiving chronic intraspinal opioids. risk summary based on two small clinical studies, methadone was present in low levels in human milk, but the exposed infants in these studies did not show adverse reactions. based on an average milk consumption of 150 ml/kg/day, an infant would consume approximately 17.4 mcg/kg/day which is approximately 2 to 3% of the oral maternal dose. there have been rare case reports of sedation and respiratory depression in infants exposed to methadone through breast milk (see  data ). monitor infants exposed to methadone hydrochloride through breastmilk for excess sedation and respiratory depression. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for methadone and any potential adverse effects on the breastfed child from the drug or from the underlying maternal condition. data in a study of ten breastfeeding women maintained on oral methadone doses of 10 to 80 mg/day, methadone concentrations from 50 to 570 mcg/l in milk were reported, which, in the majority of samples, were lower than maternal serum drug concentrations at steady state. peak methadone levels in milk occur approximately 4 to 5 hours after an oral dose. in a study of twelve breastfeeding women maintained on oral methadone doses of 20 to 80 mg/day, methadone concentrations from 39 to 232 mcg/l in milk were reported. based on an average milk consumption of 150 ml/kg/day, an infant would consume approximately 17.4 mcg/kg/day, which is approximately 2 to 3% of the oral maternal dose. methadone has been detected in very low plasma concentrations in some infants whose mothers were taking methadone. infertility the effect of methadone hydrochloride tablets on fertility is unknown. 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), clinical pharmacology (12.2), nonclinical pharmacology (13.1) ]. reproductive function in human males may be decreased by methadone treatment. reductions in ejaculate volume and seminal vesicle and prostate secretions have been reported in methadone-treated individuals. in addition, reductions in serum testosterone levels and sperm motility, and abnormalities in sperm morphology have been reported. in published animal studies, methadone produces a significant regression of sex accessory organs and testes of male mice and rats and administration of methadone to pregnant rats reduced fetal blood testosterone and androstenedione in male offspring [see nonclinical toxicology (13)]. the safety, effectiveness, and pharmacokinetics of methadone in pediatric patients below the age of 18 years have not been established. clinical studies of methadone did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently compared to younger subjects. other reported clinical experience has not identified differences in responses between elderly and younger patients. elderly patients (aged 65 years or older) may have increased sensitivity to methadone. 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 methadone hydrochloride tablets slowly in geriatric patients and monitor closely for signs of central nervous system and respiratory depression [see warnings and precautions (5.8)] . methadone is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. methadone pharmacokinetics have not been extensively evaluated in patients with hepatic insufficiency. methadone is metabolized by hepatic pathways; therefore, patients with liver impairment may be at risk of increased systemic exposure to methadone after multiple dosing. start these patients on lower doses and titrate slowly while carefully monitoring for signs of respiratory and central nervous system depression. methadone pharmacokinetics have not been extensively evaluated in patients with renal insufficiency. since unmetabolized methadone and its metabolites are excreted in urine to a variable degree, start these patients on lower doses and with longer dosing intervals and titrate slowly while carefully monitoring for signs of respiratory and central nervous system depression. methadone hydrochloride tablets contain methadone, a schedule ii controlled substance. methadone hydrochloride tablets contain methadone, a substance with a high potential for abuse similar to other opioids including fentanyl, hydrocodone, hydromorphone, morphine, oxycodone, oxymorphone, and tapentadol. methadone hydrochloride tablets can be abused and are subject to misuse, addiction, and criminal diversion [see warnings and precautions (5.1)]. all patients treated with opioids for pain management require careful monitoring for signs of abuse and addiction, since use of opioid analgesic products carries the risk of addiction even under appropriate medical use. prescription drug abuse is the intentional non-therapeutic use of a prescription drug, even once, for its rewarding psychological or physiological effects. drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes: a strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful consequences, a higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes a physical withdrawal. “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 drug abusers and people suffering from untreated addiction. preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with poor pain control. abuse and addiction are separate and distinct from physical dependence and tolerance. healthcare providers should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. in addition, abuse of opioids can occur in the absence of true addiction. methadone hydrochloride tablets, like other opioids, can be diverted for non-medical 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 and selection of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs. risks specific to abuse of methadone hydrochloride tablets abuse of methadone hydrochloride tablets poses a risk of overdose and death. this risk is increased with concurrent abuse of methadone and alcohol or other substances. methadone hydrochloride tablets are for oral use only and must not be injected. with intravenous abuse the inactive ingredients in methadone hydrochloride tablets can result in local tissue necrosis, infection, pulmonary granulomas, embolism and death, and increased risk of endocarditis and valvular heart injury. parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and hiv. both tolerance and physical dependence can develop during chronic opioid therapy. tolerance is the need for increasing doses of opioids to maintain a defined effect such as analgesia (in the absence of disease progression or other external factors). tolerance may occur to both the desired and undesired effects of drugs, and may develop at different rates for different effects. physical dependence is a physiological state in which the body adapts to the drug after a period of regular exposure, resulting in withdrawal symptoms after abrupt discontinuation or a significant dosage reduction of a drug. withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity (e.g., naloxone, nalmefene), 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 opioid usage. do not abruptly discontinue methadone hydrochloride tablets in a patient physically dependent on opioids. rapid tapering of methadone hydrochloride tablets 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 methadone hydrochloride tablets, gradually taper the dosage using a patient-specific plan that considers the following: the dose of methadone hydrochloride tablets 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 a long duration 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 (2.6), warnings (5.15)] . 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) ]. neonatal opioid withdrawal syndrome (nows) is an expected and treatable outcome of prolonged use of opioids during pregnancy [see warnings and precautions (5.5) ].

bryant ranch prepack - hydromorphone hydrochloride (unii: l960up2krw) (hydromorphone - unii:q812464r06) - hydromorphone hydrochloride suppositories are indicated for the management of pain 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, even at recommended doses [see warnings and precautions (5.1)] , reserve hydromorphone hydrochloride suppositories for use in patients for whom alternative treatment options [e.g., non-opioid analgesics or opioid combination products]: hydromorphone hydrochloride suppositories are contraindicated in patients with: risk summary prolonged use of opioid analgesics during pregnancy may cause neonatal opioid withdrawal syndrome [see warnings and precautions (5.3)] . there are no available data with hydromorphone hydrochloride in pregnant women to inform a drug-associated risk for major birth defects and miscarriage. in animal reproduction studies, reduced postnatal survival of pups, and decreased were noted following oral treatment of pregnant rats with hydromorphone during gestation and through lactation at doses 0.8 times the human daily dose of 24 mg/day (hdd), respectively. in published studies, neural tube defects were noted following subcutaneous injection of hydromorphone to pregnant hamsters at doses 6.4 times the hdd and soft tissue and skeletal abnormalities were noted following subcutaneous continuous infusion of 3 times the hdd to pregnant mice. no malformations were noted at 4 or 40.5 times the hdd in pregnant rats or rabbits, respectively [see data]. based on animal data, advise pregnant women of the potential risk to a fetus. 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 2-4% and 15-20%, respectively. clinical considerations fetal/neonatal adverse reactions prolonged use of opioid analgesics 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 (5.3)] . 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. hydromorphone hydrochloride suppositories are not recommended for use in pregnant women during or immediately prior to labor, when other analgesic techniques are more appropriate. opioid analgesics, including hydromorphone hydrochloride suppositories, 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 pregnant rats were treated with hydromorphone hydrochloride from gestation day 6 to 17 via oral gavage doses of 1, 5, or 10 mg/kg/day (0.4, 2, or 4 times the hdd of 24 mg based on body surface area, respectively). maternal toxicity was noted in all treatment groups (reduced food consumption and body weights in the two highest dose groups). there was no evidence of malformations or embryotoxicity reported. pregnant rabbits were treated with hydromorphone hydrochloride from gestation day 7 to 19 via oral gavage doses of 10, 25, or 50 mg/kg/day (8.1, 20.3, or 40.5 times the hdd of 24 mg based on body surface area, respectively). maternal toxicity was noted in the two highest dose groups (reduced food consumption and body weights). there was no evidence of malformations or embryotoxicity reported. in a published study, neural tube defects (exencephaly and cranioschisis) were noted following subcutaneous administration of hydromorphone hydrochloride (19 to 258 mg/kg) on gestation day 8 to pregnant hamsters (6.4 to 87.2 times the hdd of 24 mg/day based on body surface area). the findings cannot be clearly attributed to maternal toxicity. no neural tube defects were noted at 14 mg/kg (4.7 times the human daily dose of 24 mg/day). in a published study, cf-1 mice were treated subcutaneously with continuous infusion of 7.5, 15, or 30 mg/kg/day hydromorphone hydrochloride (1.5, 3, or 6.1 times the human daily dose of 24 mg based on body surface area) via implanted osmotic pumps during organogenesis (gestation days 7 to 10). soft tissue malformations (cryptorchidism, cleft palate, malformed ventricles and retina), and skeletal variations (split supraoccipital, checkerboard and split sternebrae, delayed ossification of the paws and ectopic ossification sites) were observed at doses 3 times the human dose of 24 mg/day based on body surface area. the findings cannot be clearly attributed to maternal toxicity. increased pup mortality and decreased pup body weights were noted at 0.8 and 2 times the human daily dose of 24 mg in a study in which pregnant rats were treated with hydromorphone hydrochloride from gestation day 7 to lactation day 20 via oral gavage doses of 0, 0.5, 2, or 5 mg/kg/day (0.2, 0.8, or 2 times the hdd of 24 mg based on body surface area, respectively). maternal toxicity (decreased food consumption and body weight gain) was also noted at the two highest doses tested. risk summary low levels of opioid analgesics have been detected in human milk. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for hydromorphone hydrochloride suppositories and any potential adverse effects on the breastfed infant from hydromorphone hydrochloride suppositories or from the underlying maternal condition. clinical considerations monitor infants exposed to hydromorphone hydrochloride through breast milk for excess sedation and respiratory depression. withdrawal symptoms can occur in breastfed infants when maternal administration of hydromorphone is stopped, or when breast-feeding is stopped. 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 hydromorphone hydrochloride in pediatric patients have not been established. elderly patients (aged 65 years or older) may have increased sensitivity to hydromorphone. 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,

more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. the pharmacokinetics of hydromorphone is affected by hepatic impairment. due to increased exposure of hydromorphone, patients with hepatic impairment should be started at one-fourth to one-half the recommended starting dose depending on the degree of hepatic dysfunction and closely monitored during dose titration. the pharmacokinetics of hydromorphone in patients with severe hepatic impairment has not been studied. a further increase in cmax and auc of hydromorphone in this group is expected and should be taken into consideration when selecting a starting dose [see clinical pharmacology (12.3)] . the pharmacokinetics of hydromorphone is affected by renal impairment. in addition, in patients with severe renal impairment, hydromorphone appeared to be more slowly eliminated with a longer terminal elimination half-life. start patients with renal impairment on one-fourth to one-half the usual starting dose depending on the degree of impairment. patients with renal impairment should be closely monitored during dose titration [see clinical pharmacology (12.3)]. hydromorphone hydrochloride suppositories contain hydromorphone, a schedule ii controlled substance. hydromorphone hydrochloride suppositories contain hydromorphone, a substance

nucare pharmaceuticals,inc. - tramadol hydrochloride (unii: 9n7r477wck) (tramadol - unii:39j1lgj30j) - tramadol hydrochloride tablets are indicated in adults for the management of pain 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, even at recommended doses [see warnings and precautions (5.1)] , reserve tramadol hydrochloride tablets for use in patients for whom alternative treatment options [e.g., non-opioid analgesics]: - have not been tolerated or are not expected to be tolerated. - have not provided adequate analgesia or are not expected to provide adequate analgesia. tramadol hydrochloride tablets are contraindicated for: - all children younger than 12 years of age [see warnings and precautions (5.4)] . - postoperative management in children younger than 18 years of age following tonsillectomy and/or adenoidectomy [see warnings and precautions (5.4)] . tramadol hydrochloride tablets are also contraindicated in patients with: - significant respiratory depression [see warnings and precautions (5.3)] . - acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment [see warnings and precautions (5.12)] . - known or suspected gastrointestinal obstruction, including paralytic ileus [see warnings and

use within the last 14 days [see drug interactions (7)] . risk summary prolonged use of opioid analgesics during pregnancy may cause neonatal opioid withdrawal syndrome. available data with tramadol hydrochloride in pregnant women are insufficient to inform a drug-associated risk for major birth defects and miscarriage. in animal reproduction studies, tramadol administration during organogenesis decreased fetal weights and reduced ossification in mice, rats, and rabbits at 1.4, 0.6, and 3.6 times the maximum recommended human daily dosage (mrhd). tramadol decreased pup body weight and increased pup mortality at 1.2 and 1.9 times the mrhd [see data] . based on animal data, advise pregnant women of the potential risk to a fetus. 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 prolonged use of opioid analgesics during pregnancy for medical or nonmedical purposes can result in respiratory depression and physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth. neonatal opioid withdrawal syndrome can present 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 and signs of neonatal opioid withdrawal syndrome and manage accordingly [see warnings and precautions (5.5)] . neonatal seizures, neonatal withdrawal syndrome, fetal death and still birth have been reported during postmarketing. 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. tramadol hydrochloride is not recommended for use in pregnant women during or immediately prior to labor, when other analgesic techniques are more appropriate. opioid analgesics, including tramadol hydrochloride, 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. tramadol has been shown to cross the placenta. the mean ratio of serum tramadol in the umbilical veins compared to maternal veins was 0.83 for 40 women given tramadol during labor. the effect of tramadol hydrochloride, if any, on the later growth, development, and functional maturation of the child is unknown. data animal data tramadol has been shown to be embryotoxic and fetotoxic in mice, (120 mg/kg), rats (25 mg/kg) and rabbits (75 mg/kg) at maternally toxic dosages, but was not teratogenic at these dose levels. these doses on a mg/m 2 basis are 1.4, 0.6, and 3.6 times the maximum recommended human daily dosage (mrhd) for mouse, rat and rabbit, respectively. no drug-related teratogenic effects were observed in progeny of mice (up to 140 mg/kg), rats (up to 80 mg/kg) or rabbits (up to 300 mg/kg) treated with tramadol by various routes. embryo and fetal toxicity consisted primarily of decreased fetal weights, decreased skeletal ossification and increased supernumerary ribs at maternally toxic dose levels. transient delays in developmental or behavioral parameters were also seen in pups from rat dams allowed to deliver. embryo and fetal lethality were reported only in one rabbit study at 300 mg/kg, a dose that would cause extreme maternal toxicity in the rabbit. the dosages listed for mouse, rat and rabbit are 1.7, 1.9 and 14.6 times the mrhd, respectively. tramadol was evaluated in pre- and post-natal studies in rats. progeny of dams receiving oral (gavage) dose levels of 50 mg/kg 1.2 times the mrhd) or greater had decreased weights, and pup survival was decreased early in lactation at 80 mg/kg (1.9 times the mrhd). risk summary tramadol hydrochloride is not recommended for obstetrical preoperative medication or for post-delivery analgesia in nursing mothers because its safety in infants and newborns has not been studied. tramadol and its metabolite, o -desmethyltramadol (m1), are present in human milk. there is no information on the effects of the drug on the breastfed infant or the effects of the drug on milk production. the m1 metabolite is more potent than tramadol in mu opioid receptor binding [see clinical pharmacology (12)] . published studies have reported tramadol and m1 in colostrum with administration of tramadol to nursing mothers in the early post-partum period. women who are ultra-rapid metabolizers of tramadol may have higher than expected serum levels of m1, potentially leading to higher levels of m1 in breast milk that can be dangerous in their breastfed infants. in women with normal tramadol metabolism, the amount of tramadol secreted into human milk is low and dose-dependent. because of the potential for serious adverse reactions, including excess sedation and respiratory depression in a breastfed infant, advise patients that breastfeeding is not recommended during treatment with tramadol hydrochloride [see warnings and precautions (5.4)] . clinical considerations if infants are exposed to tramadol hydrochloride through breast milk, they should be monitored for excess sedation and respiratory depression. withdrawal symptoms can occur in breastfed infants when maternal administration of an opioid analgesic is stopped, or when breast-feeding is stopped. data following a single iv 100 mg dose of tramadol, the cumulative excretion in breast milk within 16 hours post dose was 100 mcg of tramadol (0.1% of the maternal dose) and 27 mcg of m1. 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)] . the safety and effectiveness of tramadol hydrochloride in pediatric patients have not been established. life-threatening respiratory depression and death have occurred in children who received tramadol [see warnings and precautions (5.4)] . in some of the reported cases, these events followed tonsillectomy and/or adenoidectomy, and one of the children had evidence of being an ultra-rapid metabolizer of tramadol (i.e., multiple copies of the gene for cytochrome p450 isoenzyme 2d6). children with sleep apnea may be particularly sensitive to the respiratory depressant effects of tramadol. because of the risk of life-threatening respiratory depression and death: - tramadol hydrochloride is contraindicated for all children younger than 12 years of age [see contraindications (4)] . - tramadol hydrochloride is contraindicated for postoperative management in pediatric patients younger than 18 years of age following tonsillectomy and/or adenoidectomy [see contraindications (4)] . avoid the use of tramadol hydrochloride in adolescents 12 to 18 years of age who have other risk factors that may increase their sensitivity to the respiratory depressant effects of tramadol unless the benefits outweigh the risks. risk factors include conditions associated with hypoventilation such as postoperative status, obstructive sleep apnea, obesity, severe pulmonary disease, neuromuscular disease, and concomitant use of other medications that cause respiratory depression. a total of 455 elderly (65 years of age or older) subjects were exposed to tramadol hydrochloride in controlled clinical trials. of those, 145 subjects were 75 years of age and older. in studies including geriatric patients, treatment-limiting adverse events were higher in subjects over 75 years of age compared to those under 65 years of age. specifically, 30% of those over 75 years of age had gastrointestinal treatment-limiting adverse events compared to 17% of those under 65 years of age. constipation resulted in discontinuation of treatment in 10% of those over 75. 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 tramadol hydrochloride slowly in geriatric patients starting at the low end of the dosing range and monitor closely for signs of central nervous system and respiratory depression [see warnings and precautions (5.12)] . tramadol is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. impaired renal function results in a decreased rate and extent of excretion of tramadol and its active metabolite, m1. in patients with creatinine clearances of less than 30 ml/min, dosing reduction is recommended [see dosage and administration (2.3)] . metabolism of tramadol and m1 is reduced in patients with severe hepatic impairment based on a study in patients with advanced cirrhosis of the liver. in patients with severe hepatic impairment, dosing reduction is recommended [see dosage and administration (2.3)] . with the prolonged half-life in these conditions, achievement of steady-state is delayed, so that it may take several days for elevated plasma concentrations to develop. tramadol hydrochloride contain tramadol, a schedule iv controlled substance. tramadol hydrochloride contains tramadol, a substance with a high potential for abuse similar to other opioids. tramadol hydrochloride can be abused and is subject to misuse, addiction, and criminal diversion [see warnings and precautions (5.1)] . all patients treated with opioids require careful monitoring for signs of abuse and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use. prescription drug abuse is the intentional non-therapeutic use of a prescription drug, even once, for its rewarding psychological or physiological effects. drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes: a strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful, or potentially harmful, consequences, a higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes a physical withdrawal. “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 physician(s). “doctor shopping” (visiting multiple prescribers to obtain additional prescriptions) is common among drug abusers and people suffering from untreated addiction. preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with poor pain control. abuse and addiction are separate and distinct from physical dependence and tolerance. healthcare providers should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. in addition, abuse of opioids can occur in the absence of true addiction. tramadol hydrochloride, like other opioids, can be diverted for non-medical 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 re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs. risks specific to abuse of tramadol hydrochloride tramadol hydrochloride is intended for oral use only. abuse of tramadol hydrochloride poses a risk of overdose and death. the risk is increased with concurrent abuse of tramadol hydrochloride with alcohol and other central nervous system depressants. parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and hiv. both tolerance and physical dependence can develop during chronic opioid therapy. tolerance is the need for increasing doses of drugs to maintain a defined effect such as analgesia (in the absence of disease progression or other external factors). tolerance may occur to both the desired and undesired effects of drugs, and may develop at different rates for different effects. physical dependence is a physiological state in which the body adapts to the drug after a period of regular exposure, resulting in withdrawal symptoms after abrupt discontinuation or a significant dosage reduction of a drug. withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity (e.g., naloxone, nalmefene), mixed agonist/antagonist analgesics (pentazocine, butorphanol, nalbuphine), or partial agonists (buprenorphine). physical dependence may not occur to a clinically significant degree until after several days to weeks of continued opioid usage. do not abruptly discontinue tramadol hydrochloride in a patient physically dependent on opioids. rapid tapering of tramadol hydrochloride 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 tramadol hydrochloride, gradually taper the dosage using a patient-specific plan that considers the following: the dose of tramadol hydrochloride 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 a long duration 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), warnings and precautions (5.17)] . 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)] .
