been reported to experience symptoms of sedation and neonatal withdrawal [see warnings and precautions ( 5.4), clinical considerations)] . overall available data from published observational studies of pregnant women exposed to alprazolam have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes (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 risk of major birth defects and of miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. clinical considerations fetal/neonatal adverse reactions benzodiazepines cross the placenta and may produce respiratory depression and sedation in neonates. monitor neonates exposed to benzodiazepines during pregnancy and labor for signs of sedation, respiratory depression, withdrawal, and feeding problems and manage accordingly [see warnings and precautions ( 5.4)]. data human data published data from observational studies on the use of benzodiazepines during pregnancy do not report a clear association with benzodiazepines and major birth defects. although early studies reported an increased risk of congenital malformations with diazepam and chlordiazepoxide, there was no consistent pattern noted. in addition, the majority of recent case-control and cohort studies of benzodiazepine use during pregnancy, which were adjusted for confounding exposures to alcohol, tobacco, and other medications, have not confirmed these findings. at this time, there is no clear evidence that alprazolam exposure in early pregnancy can cause major birth defects. neonates exposed to benzodiazepines during the late third trimester of pregnancy or during labor have been reported to exhibit sedation and neonatal withdrawal symptoms. risk summary limited data from published literature reports the presence of alprazolam in human breast milk. there are reports of sedation and withdrawal symptoms in breastfed neonates and infants exposed to alprazolam. the effects of alprazolam on lactation are unknown. because of the potential for serious adverse reactions, including sedation and withdrawal symptoms in breastfed neonates and infants, advise patients that breastfeeding is not recommended during treatment with alprazolam. safety and effectiveness of alprazolam have not been established in pediatric patients. alprazolam-treated geriatric patients had higher plasma concentrations of alprazolam (due to reduced clearance) compared to younger adult patients receiving the same doses. therefore, dosage reduction of alprazolam is recommended in geriatric patients [see dosage and administration ( 2.4) and clinical pharmacology ( 12.3)] . patients with alcoholic liver disease exhibit a longer elimination half-life (19.7 hours), compared to healthy subjects (11.4 hours). this may be caused by decreased clearance of alprazolam in patients with alcoholic liver disease. dosage reduction of alprazolam is recommended in patients with hepatic impairment [see dosage and administration (2.4), clinical pharmacology (12.3)] . alprazolam tablets contain alprazolam, which is a schedule iv controlled substance. alprazolam tablets are a benzodiazepine and a cns depressant with a potential for abuse and addiction. abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects. misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a health care provider or for whom it was not prescribed. 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. even taking benzodiazepines as prescribed may put patients at risk for abuse and misuse of their medication. abuse and misuse of benzodiazepines may lead to addiction. abuse and misuse of benzodiazepines often (but not always) involve the use of doses greater than the maximum recommended dosage and commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes, including respiratory depression, overdose, or death. benzodiazepines are often sought by individuals who abuse drugs and other substances, and by individuals with addictive disorders [see warnings and precautions ( 5.2)] . the following adverse reactions have occurred with benzodiazepine abuse and/or misuse: abdominal pain, amnesia, anorexia, anxiety, aggression, ataxia, blurred vision, confusion, depression, disinhibition, disorientation, dizziness, euphoria, impaired concentration and memory, indigestion, irritability, muscle pain, slurred speech, tremors, and vertigo. the following severe adverse reactions have occurred with benzodiazepine abuse and/or misuse: delirium, paranoia, suicidal ideation and behavior, seizures, coma, breathing difficulty, and death. death is more often associated with polysubstance use (especially benzodiazepines with other cns depressants such as opioids and alcohol). alprazolam tablets may produce physical dependence from continued therapy. physical dependence is a state that develops as a result of 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. abrupt discontinuation or rapid dosage reduction of benzodiazepines or administration of flumazenil, a benzodiazepine antagonist, may precipitate acute withdrawal reactions, including seizures, which can be life-threatening. patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages (i.e., higher and/or more frequent doses) and those who have had longer durations of use [see warnings and precautions ( 5.3)] . to reduce the risk of withdrawal reactions, use a gradual taper to discontinue alprazolam tablets or reduce the dosage [see dosage and administration ( 2.3), warnings and precautions ( 5.3)] . acute withdrawal signs and symptoms acute withdrawal signs and symptoms associated with benzodiazepines have included abnormal involuntary movements, anxiety, blurred vision, depersonalization, depression, derealization, dizziness, fatigue, gastrointestinal adverse reactions (e.g., nausea, vomiting, diarrhea, weight loss, decreased appetite), headache, hyperacusis, hypertension, irritability, insomnia, memory impairment, muscle pain and stiffness, panic attacks, photophobia, restlessness, tachycardia, and tremor. more severe acute withdrawal signs and symptoms, including life-threatening reactions, have included catatonia, convulsions, delirium tremens, depression, hallucinations, mania, psychosis, seizures, and suicidality. protracted withdrawal syndrome protracted withdrawal syndrome associated with benzodiazepines is characterized by anxiety, cognitive impairment, depression, insomnia, formication, motor symptoms (e.g., weakness, tremor, muscle twitches), paresthesia, and tinnitus that persists beyond 4 to 6 weeks after initial benzodiazepine withdrawal. protracted withdrawal symptoms may last weeks to more than 12 months. as a result, there may be difficulty in differentiating withdrawal symptoms from potential re-emergence or continuation of symptoms for which the benzodiazepine was being used. tolerance tolerance to alprazolam may develop from continued 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). tolerance to the therapeutic effect of alprazolam may develop; however, little tolerance develops to the amnestic reactions and other cognitive impairments caused by benzodiazepines.

remedyrepack 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 is 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 is 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 precautions (5.15) ] . - hypersensitivity to tramadol, any other component of this product or opioids [see warnings and precautions (5.16) ] . - concurrent use of monoamine oxidase inhibitors (maois) or 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 tablets contains tramadol, a schedule iv controlled substance. tramadol hydrochloride tablets 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)] .

"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. oxycodone and acetaminophen tablets, 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 oxycodone and acetaminophen tablets abuse of oxycodone and acetaminophen tablets poses a risk of overdose and death. the risk is increased with concurrent use of oxycodone and acetaminophen tablets with alcohol and/or other cns depressants. 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 oxycodone and acetaminophen tablets in a patient physically dependent on opioids. rapid tapering of oxycodone and acetaminophen 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 oxycodone and acetaminophen tablets, gradually taper the dosage using a patient-specific plan that considers the following: the dose of oxycodone and acetaminophen 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,  warnings ]. infants born to mothers physically dependent on opioids will also be physically dependent and may exhibit respiratory difficulties and withdrawal signs [see precautions; pregnancy ].

remedyrepack inc. - temazepam (unii: chb1qd2qss) (temazepam - unii:chb1qd2qss) - temazepam capsules are indicated for the short-term treatment of insomnia (generally 7 to 10 days). for patients with short-term insomnia, instructions in the prescription should indicate that temazepam capsules should be used for short periods of time (7 to 10 days). the clinical trials performed in support of efficacy were 2 weeks in duration with the final formal assessment of sleep latency performed at the end of treatment. temazepam capsules are a schedule iv controlled substance. temazepam is a benzodiazepine and a cns depressant with a potential for abuse and addiction. abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects. 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. 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. even taking benzodiazepines as prescribed may put patients at risk for abuse and misuse of their medication. abuse and misuse of benzodiazepines may lead to addiction. abuse and misuse of benzodiazepines often (but not always) involve the use of doses greater than the maximum recommended dosage and commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes, including respiratory depression, overdose, or death. benzodiazepines are often sought by individuals who abuse drugs and other substances, and by individuals with addictive disorders ( see warnings, abuse, misuse, and addiction ). the following adverse reactions have occurred with benzodiazepine abuse and/or misuse: abdominal pain, amnesia, anorexia, anxiety, aggression, ataxia, blurred vision, confusion, depression, disinhibition, disorientation, dizziness, euphoria, impaired concentration and memory, indigestion, irritability, muscle pain, slurred speech, tremors, and vertigo. the following severe adverse reactions have occurred with benzodiazepine abuse and/or misuse: delirium, paranoia, suicidal ideation and behavior, seizures, coma, breathing difficulty, and death. death is more often associated with polysubstance use (especially benzodiazepines with other cns depressants such as opioids and alcohol). physical dependence temazepam may produce physical dependence from continued therapy. physical dependence is a state that develops as a result of 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. abrupt discontinuation or rapid dosage reduction of benzodiazepines or administration of flumazenil, a benzodiazepine antagonist, may precipitate acute withdrawal reactions, including seizures, which can be life-threatening. patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages (i.e., higher and/or more frequent doses) and those who have had longer durations of use ( see warnings, dependence and withdrawal reactions ). to reduce the risk of withdrawal reactions, use a gradual taper to discontinue temazepam capsules or reduce the dosage ( see dosage and administration, discontinuation or dosage reduction of temazepam capsules  and warnings, dependence and withdrawal reactions ). acute withdrawal signs and symptoms acute withdrawal signs and symptoms associated with benzodiazepines have included abnormal involuntary movements, anxiety, blurred vision, depersonalization, depression, derealization, dizziness, fatigue, gastrointestinal adverse reactions (e.g., nausea, vomiting, diarrhea, weight loss, decreased appetite), headache, hyperacusis, hypertension, irritability, insomnia, memory impairment, muscle pain and stiffness, panic attacks, photophobia, restlessness, tachycardia, and tremor. more severe acute withdrawal signs and symptoms, including life-threatening reactions, have included catatonia, convulsions, delirium tremens, depression, hallucinations, mania, psychosis, seizures, and suicidality. protracted withdrawal syndrome protracted withdrawal syndrome with benzodiazepines is characterized by anxiety, cognitive impairment, depression, insomnia, formication, motor symptoms (e.g., weakness, tremor, muscle twitches), paresthesia, and tinnitus that persists beyond 4 to 6 weeks after initial benzodiazepine withdrawal. protracted withdrawal symptoms may last weeks to more than 12 months. as a result, there may be difficulty in differentiating withdrawal symptoms from potential re-emergence or continuation of symptoms for which the benzodiazepine was being used. tolerance tolerance to temazepam may develop from continued 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). tolerance to the therapeutic effect of temazepam may develop; however, little tolerance develops to the amnestic reactions and other cognitive impairments caused by benzodiazepines.

remedyrepack 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 ofuse: 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 tramadol hydrochloride tablets for use in patients forwhom alternative treatment options (e.g., non-opioid analgesics or opioid combination products): - have not been tolerated orare not expected to be tolerated, - have not provided adequate analgesia orare not expected to provide adequate analgesia. tramadol hydrochloride tablets should not be used for anextended period of time unless the pain remains severe enough to require an opioid analgesic and for which alternative treatment options continue to be inadequate. tramadol hydrochloride tablets are contraindicated for: - all children younger than 12 years of age [see warnings and precautions (5.6)] . - postoperative management in children younger than 18 years of age following tonsillectomy and/or adenoidectomy [see warnings and precautions (5.6)] . tramadol hydrochloride tablets are also 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 (5.12)] . - known or suspected gastrointestinal obstruction, including paralytic ileus [see warnings and precautions (5.16)] . - hypersensitivity to tramadol, any other component of this product or opioids [see warnings and precautions (5.17)] . - concurrent use of monoamine oxidase inhibitors (maois) or use within the last 14 days [see drug interactions (7)] . 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)]. 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 use of opioid analgesics for an extended period of time 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 (5.4)] . 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 (5.6)] . 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 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 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 (5.6)] . 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 frequently reevaluate the patient 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 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 health care provider or for whom it was not prescribed. abuse is the intentional, non-therapeutic use of a 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 tramadol hydrochloride increases risk of overdosage, which may lead to central nervous system and respiratory depression, hypotension, seizures, and death. the risk is increased with concurrent abuse of tramadol hydrochloride with alcohol and other central nervous system 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 re-evaluation 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 tramadol hydrochloride abuse include those with a history of prolonged use of products containing tramadol, those with a history of drug or alcohol abuse, or those who use tramadol hydrochloride 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. 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 reevaluation 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 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. tramadol hydrochloride is approved for oral use only. parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and hiv. 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 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 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 (5.18)]. 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)].
