indicated for the management of severe and persistent pain that requires an extended treatment period with a daily opioid analgesic and for which alternative treatment options are inadequate. limitations of use - because of the risks of addiction, abuse, and misuse with opioids, which can occur at any dosages or duration, and because of the greater risks of overdose and death with extended-release/long-acting opioid formulations [see warnings and precautions (5.1)] , reserve tramadol hydrochloride extended-release tablets for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. - tramadol hydrochloride extended-release tablets are not indicated as an as-needed (prn) analgesic. tramadol hydrochloride extended-release tablets are contraindicated for: - all children younger than 12 years of age [see warnings and precautions (5.6)] - post-operative management in children younger than 18 years of age following tonsillectomy and/or adenoidectomy [see warnings and precautions (5.6)] . tramadol hydrochloride extended-release 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 (e.g., anaphylaxis) [see warnings and precautions (5.17), adverse reactions (6.2)] - 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 extended-release tablets 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 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 and signs of neonatal opioid withdrawal syndrome and manage accordingly [see warnings and precautions (5.4)] . neonatal seizures, neonatal withdrawal syndrome, fetal death and stillbirth have been reported with tramadol during post-approval use of tramadol immediate-release products. 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 extended-release tablets are not recommended for use in pregnant women during or immediately prior to labor, when use of shorter-acting analgesics or other analgesic techniques are more appropriate. opioid analgesics, including tramadol hydrochloride extended-release tablets, 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 extended-release tablets, 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/m2 basis are 1.9, 0.8, and 4.9 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 2.3, 2.6, and 19 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 (1.6 times the mrhd) or greater had decreased weights, and pup survival was decreased early in lactation at 80 mg/kg (2.6 times the mrhd). risk summary tramadol hydrochloride extended-release tablets are 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-desmethyl tramadol (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 (12.1) ]. 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 extended-release tablets. clinical considerations if infants are exposed to tramadol hydrochloride extended-release tablets 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), clinical pharmacology (12.2), nonclinical toxicology (13.1) ]. the safety and effectiveness of tramadol hydrochloride extended-release tablets 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 extended-release tablets are contraindicated for all children younger than age 12 years of age [see contraindications (4) ]. - tramadol hydrochloride extended-release tablets are contraindicated for post-operative management in pediatric patients younger than 18 years of age following tonsillectomy and/or adenoidectomy [see  contraindications (4) ]. - avoid the use of tramadol hydrochloride extended-release tablets 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. [see warnings and precautions (5.6)] . nine-hundred-one elderly (65 years of age or older) subjects were exposed to tramadol hydrochloride extended-release tablets in clinical trials. of those subjects, 156 were 75 years of age and older. in general, higher incidence rates of adverse events were observed for patients older than 65 years of age compared with patients 65 years and younger, particularly for the following adverse events: constipation, fatigue, weakness, postural hypotension and dyspepsia. for this reason, tramadol hydrochloride extended-release tablets should be used with caution in patients over 65 years of age, and with even greater caution in patients older than 75 years of age [see dosage and administration (2.5), clinical pharmacology (12.3)]. 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 opioidtolerant or when opioids were co-administered with other agents that depress respiration. titrate the dosage of tramadol hydrochloride extended-release tablets slowly in geriatric patients 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. metabolism of tramadol and m1 is reduced in patients with advanced cirrhosis of the liver. tramadol hydrochloride extended-release tablets have not been studied in patients with severe hepatic impairment. the limited availability of dose strengths and once daily dosing of tramadol hydrochloride extended-release tablets do not permit the dosing flexibility required for safe use in patients with severe hepatic impairment (child-pugh class c). therefore, tramadol hydrochloride extended-release tablets should not be used in patients with severe hepatic impairment [see clinical pharmacology (12.3) ]. impaired renal function results in a decreased rate and extent of excretion of tramadol and its active metabolite, m1. tramadol hydrochloride extended-release tablets have not been studied in patients with severe renal impairment (clcr < 30 ml/min). the limited availability of dose strengths and once daily dosing of tramadol hydrochloride extended-release tablets do not permit the dosing flexibility required for safe use in patients with severe renal impairment (child-pugh class c). therefore, tramadol hydrochloride extended-release tablets should not be used in patients with severe renal impairment [see clinical pharmacology (12.3)] . tramadol hydrochloride extended-release tablet contains tramadol, a scheduled iv controlled substance. tramadol hydrochloride extended-release tablets contain tramadol, a substance with high potential for misuse and abuse, which can lead to the development of substance use disorder, including addiction [see warnings and precautions (5.1)] . misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a healthcare provider or for whom it was not prescribed. abuse is the intentional, non-therapeutic use of a 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 extended-release tablets increases risk of overdose, which may lead to central nervous system and respiratory depression, hypotension, seizures, and death. the risk is increased with concurrent abuse of tramadol hydrochloride extended-release tablets with alcohol and other cns depressants. abuse of and addiction to opioids in some individuals may not be accompanied by concurrent tolerance and symptoms of physical dependence. in addition, abuse of opioids can occur in the absence of addiction. all patients treated with opioids require careful and frequent reevaluation for signs of misuse, abuse, and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use. patients at high risk of tramadol hydrochloride extended-release tablets abuse include those with a history of prolonged use of any opioid, including products containing tramadol, those with a history of drug or alcohol abuse, or those who use tramadol hydrochloride extended-release tablets 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 extended-release 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 tramadol hydrochloride extended-release tablets abuse of tramadol hydrochloride extended-release tablets poses a risk of overdose and death. this is increased with concurrent use of tramadol hydrochloride extended-release tablets with alcohol and/or other cns depressants. tramadol hydrochloride extended-release tablets is approved for oral use only. inappropriate intravenous, intramuscular, or subcutaneous use of tramadol hydrochloride extended-release tablets can result in death, local tissue necrosis, infection, pulmonary granulomas, increased risk of endocarditis, and valvular heart injury, and embolism. parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and hiv. with parenteral abuse the inactive ingredients can result in local tissue necrosis, infection, pulmonary granulomas, increased risk of endocarditis and valvular heart injury, embolism, and death. 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 extended-release tablets in a patient physically dependent on opioids. rapid tapering of tramadol hydrochloride extended-release 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 tramadol hydrochloride extended-release tablets, gradually taper the dosage using a patient-specific plan that considers the following: the dose of tramadol hydrochloride extended-release 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 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 )].

morphine sulfate in pregnant women to inform a drug-associated risk for major birth defects and miscarriage. published studies with morphine use during pregnancy have not reported a clear association with morphine and major birth defects [see human data]. in published animal reproduction studies, morphine administered subcutaneously during the early gestational period produced neural tube defects (i.e., exencephaly and cranioschisis) at 5 and 16 times the human daily dose of 60 mg based on body surface area (hdd) in hamsters and mice, respectively, lower fetal body weight and increased incidence of abortion at 0.4 times the hdd in the rabbit, growth retardation at 6 times the hdd in the rat, and axial skeletal fusion and cryptorchidism at 16 times the hdd in the mouse. administration of morphine sulfate to pregnant rats during organogenesis and through lactation resulted in cyanosis, hypothermia, decreased brain weights, pup mortality, decreased pup body weights, and adverse effects on reproductive tissues at 3 to 4 times the hdd; 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 [see animal 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 physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after

respiratory depression. data human data the results from a population-based prospective cohort, including 70 women exposed to morphine during the first trimester of pregnancy and 448 women exposed to morphine at any time during pregnancy, indicate no increased risk for congenital malformations. however, these studies cannot definitely establish the absence of any risk because of methodological limitations, including small sample size and non-randomized study design. animal data formal reproductive and developmental toxicology studies for morphine have not been conducted. exposure margins for the following published study reports are based on human daily dose of 60 mg morphine using a body surface area comparison (hdd). neural tube defects (exencephaly and cranioschisis) were noted following subcutaneous administration of morphine sulfate (35-322 mg/kg) on gestation day 8 to pregnant hamsters (4.7 to 43.5 times the hdd). a no adverse effect level was not defined in this study and the findings cannot be clearly attributed to maternal toxicity. neural tube defects (exencephaly), axial skeletal fusions, and cryptorchidism were reported following a single subcutaneous (sc) injection of morphine sulfate to pregnant mice (100-500 mg/kg) on gestation day 8 or 9 at 200 mg/kg or greater (16 times the hdd) and fetal resorption at 400 mg/kg or higher (32 times the hdd). no adverse effects were noted following 100 mg/kg morphine in this model (8 times the hdd). in one study, following continuous subcutaneous infusion of doses greater than or equal to 2.72 mg/kg to mice (0.2 times the hdd), exencephaly, hydronephrosis, intestinal hemorrhage, split supraoccipital, malformed sternebrae, and malformed xiphoid were noted. the effects were reduced with increasing daily dose; possibly due to rapid induction of tolerance under these infusion conditions. the clinical significance of this report is not clear. decreased fetal weights were observed in pregnant rats treated with 20 mg/kg/day morphine sulfate (3.2 times the hdd) from gestation day 7 to 9. there was no evidence of malformations despite maternal toxicity (10% mortality). in a second rat study, decreased fetal weight and increased incidences of growth retardation were noted at 35 mg/kg/day (5.7 times the hdd) and there was a reduced number of fetuses at 70 mg/kg/day (11.4 times the hdd) when pregnant rats were treated with 10, 35, or 70 mg/kg/day morphine sulfate via continuous infusion from gestation day 5 to 20. there was no evidence of fetal malformations or maternal toxicity. an increased incidence of abortion was noted in a study in which pregnant rabbits were treated with 2.5 (0.8 times the hdd) to 10 mg/kg morphine sulfate via subcutaneous injection from gestation day 6 to 10. in a second study, decreased fetal body weights were reported following treatment of pregnant rabbits with increasing doses of morphine (10-50 mg/kg/day) during the pre-mating period and 50 mg/kg/day (16 times the hdd) throughout the gestation period. no overt malformations were reported in either publication; although only limited endpoints were evaluated. in published studies in rats, exposure to morphine during gestation and/or lactation periods is associated with: decreased pup viability at 12.5 mg/kg/day or greater (2 times the hdd); decreased pup body weights at 15 mg/kg/day or greater (2.4 times the hdd); decreased litter size, decreased absolute brain and cerebellar weights, cyanosis, and hypothermia at 20 mg/kg/day (3.2 times the hdd); alteration of behavioral responses (play, social-interaction) at 1 mg/kg/day or greater (0.2 times the hdd); alteration of maternal behaviors (e.g., decreased nursing and pup retrievals) in mice at 1 mg/kg or higher (0.08 times the hdd) and rats at 1.5 mg/kg/day or higher (0.2 times the hdd); and a host of behavioral abnormalities in the offspring of rats, including altered responsiveness to opioids at 4 mg/kg/day (0.7 times the hdd) or greater. fetal and/or postnatal exposure to morphine in mice and rats has been shown to result in morphological changes in fetal and neonatal brain and neuronal cell loss, alteration of a number of neurotransmitter and neuromodulator systems, including opioid and non-opioid systems, and impairment in various learning and memory tests that appear to persist into adulthood. these studies were conducted with morphine treatment usually in the range of 4 to 20 mg/kg/day (0.7 to 3.2 times the hdd). additionally, delayed sexual maturation and decreased sexual behaviors in female offspring at 20 mg/kg/day (3.2 times the hdd), and decreased plasma and testicular levels of luteinizing hormone and testosterone, decreased testes weights, seminiferous tubule shrinkage, germinal cell aplasia, and decreased spermatogenesis in male offspring were also observed at 20 mg/kg/day (3.2 times the hdd). decreased litter size and viability were observed in the offspring of male rats that were intraperitoneally administered morphine sulfate for 1 day prior to mating at 25 mg/kg/day (4.1 times the hdd) and mated to untreated females. decreased viability and body weight and/or movement deficits in both first and second generation offspring were reported when male mice were treated for 5 days with escalating doses of 120 to 240 mg/kg/day morphine sulfate (9.7 to 19.5 times the hdd) or when female mice treated with escalating doses of 60 to 240 mg/kg/day (4.9 to 19.5 times the hdd) followed by a 5-day treatment-free recovery period prior to mating. similar multigenerational findings were also seen in female rats pre-gestationally treated with escalating doses of 10 to 22 mg/kg/day morphine (1.6 to 3.6 times the hdd).  risk summary morphine is present in breast milk. published lactation studies report variable concentrations of morphine in breast milk with administration of immediate-release morphine to nursing mothers in the early postpartum period with a milk-to-plasma morphine auc ratio of 2.5:1 measured in one lactation study. however, there is insufficient information to determine the effects of morphine on the breastfed infant and the effects of morphine on milk production. lactation studies have not been conducted with extended-release morphine, including morphine sulfate. 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 morphine sulfate. clinical considerations monitor infants exposed to morphine sulfate through breast milk for excess sedation and respiratory depression. withdrawal symptoms can occur in breastfed infants when maternal administration of an opioid analgesic is stopped, or when 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)] . in published animal studies, morphine administration adversely effected fertility and reproductive endpoints in male rats and prolonged estrus cycle in female rats [see nonclinical toxicology (13)] . the safety and effectiveness in pediatric patients below the age of 18 have not been established. the pharmacokinetics of morphine sulfate have not been studied in elderly patients.  clinical studies of morphine sulfate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.  elderly patients (aged 65 years or older) may have increased sensitivity to morphine. 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 morphine sulfate slowly in geriatric patients and monitor closely for signs of central nervous system and respiratory depression [see warnings and precautions (5.6)] . morphine 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. morphine pharmacokinetics have been reported to be significantly altered in patients with cirrhosis. start these patients with a lower than usual dosage of morphine sulfate and titrate slowly while monitoring for signs of respiratory depression, sedation, and hypotension [see clinical pharmacology (12.3)]. morphine pharmacokinetics are altered in patients with renal failure. start these patients with a lower than usual dosage of morphine sulfate and titrate slowly while monitoring for signs of respiratory depression, sedation, and hypotension [see clinical pharmacology (12.3)]. morphine sulfate extended-release tablets contain morphine, a schedule ii controlled substance. morphine sulfate extended-release tablets contains morphine, a substance with a high potential for abuse similar to other opioids including fentanyl, hydrocodone, hydromorphone, methadone, oxycodone, oxymorphone, and tapentadol. morphine sulfate can be abused and is subject to misuse, addiction, and criminal diversion [see warnings and precautions (5.1)] . the high drug content in extended-release formulations adds to the risk of adverse outcomes from abuse and misuse. all patients treated with opioids require careful and frequent reevaluation for signs of misuse, abuse, and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use. patients at high risk of morphine sulfate extended-release tablets abuse include those with a history of prolonged use of any opioid, including products containing morphine sulfate, those with a history of drug or alcohol abuse, or those who use morphine sulfate extended-release tablets in combination with other abused drugs. prescription drug abuse is the intentional non-therapeutic use of an over-the-counter or 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 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. morphine sulfate, 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 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 morphine sulfate morphine sulfate extended-release tablets are for oral use only. abuse of morphine sulfate poses a risk of overdose and death. this is increased with concurrent use of morphine sulfate with alcohol and/or other cns depressants.  taking cut, broken, chewed, crushed, or dissolved morphine sulfate extended-release tablets enhances drug release and increases the risk of overdose and death.  due to the presence of talc as one of the excipients in morphine sulfate, with parenteral abuse the inactive ingredients can result in local tissue necrosis, infection, pulmonary granulomas, increased risk of endocarditis and valvular heart injury, embolism, and death. 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 morphine sulfate in a patient physically dependent on opioids. rapid tapering of morphine sulfate 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 morphine sulfate, gradually taper the dosage using a patient-specific plan that considers the following: the dose of morphine sulfate 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 and precautions (5.13)]. 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)] .
