Tramadol Hydrochloride Extended-Release

TRAMADOL HYDROCHLORIDE

Standard Dose
2 DOSAGE AND ADMINISTRATION Tramadol Hydrochloride Extended-Release Capsules should be prescribed only by healthcare professionals who are knowledgeable about the use of extended-release/long-acting opioids and how to mitigate the associated risks. ( 2.1 ) Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals. Reserve titration to higher doses of Tramadol Hydrochloride Extended-Release Capsules for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks. ( 2 , 5 ) Initiate the dosing regimen for each patient individually, taking into account the patient's underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse. ( 2.1 , 5.1 ) Respiratory depression can occur at any time during opioid therapy, especially when initiating and following dosage increases with Tramadol Hydrochloride Extended-Release Capsules. Consider this risk when selecting an initial dose and when making dose adjustments. ( 2.1 , 5.2 ) Tramadol Hydrochloride Extended-Release Capsules are administered orally once daily. ( 2.1 ) Discuss opioid overdose reversal agents and options for acquiring them with the patient and/or caregiver, both when initiating and renewing treatment with Tramadol Hydrochloride Extended-Release Capsules, especially if the patient has additional risk factors for overdose, or close contacts at risk for exposure and overdose. ( 2.2 , 5.1 , 5.2 , 5.3 ) For patients currently on tramadol IR: Calculate total 24-hr IR dose, and initiate Tramadol Hydrochloride Extended-Release Capsules at a dose rounded down to next lower 100 mg increment; then adjust dose according to need and tolerance. See full prescribing information for instructions on conversion, titration, and maintenance of therapy. ( 2.3 , 2.4 ) For patients converting from other opioid analgesics: Discontinue all other opioid analgesics other than as needed for breakthrough pain and initiate Tramadol Hydrochloride Extended-Release Capsules at a dose of 100 mg once daily, then titrate up by 100 mg increments every 5 days according to need and tolerance. ( 2.3 , 2.4 ) Do not exceed a daily dose of 300 mg tramadol. Do not use with other tramadol products. ( 2.4 ) Periodically reassess patients receiving CONZIP to evaluate the continued need for opioid analgesics to maintain pain control, for the signs or symptoms of adverse reactions, and for the development of addiction, abuse, or misuse. ( 2.4 ) Do not rapidly reduce or abruptly discontinue Tramadol Hydrochloride Extended-Release Capsules in a physically-dependent patient because rapid reduction or abrupt discontinuation of opioid analgesics has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide. ( 2.5 , 5.18 ) 2.1 Important Dosage and Administration Instructions Tramadol Hydrochloride Extended-Release Capsules should be prescribed only by healthcare professionals who are knowledgeable about the use of extended-release/long-acting opioids and how to mitigate the associated risks. Do not use Tramadol Hydrochloride Extended-Release Capsules concomitantly with other tramadol products [see Warnings and Precautions (5.7) , (5.15) ]. Do not administer Tramadol Hydrochloride Extended-Release Capsules at a dose exceeding 300 mg per day. Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals [see Warnings and Precautions (5) ] . Because the risk of overdose increases as opioid doses increase, reserve titration to higher doses of Tramadol Hydrochloride Extended-Release Capsules for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks. Initiate the dosing regimen for each patient individually, taking into account the patient's underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse [see Warnings and Precautions (5.1) ]. Respiratory depression can occur at any time during opioid therapy, especially when initiating and following dosage increases with Tramadol Hydrochloride Extended-Release Capsules. Consider this risk when selecting an initial dose and when making dose adjustments [see Warnings and Precautions (5.2) ] . Tramadol Hydrochloride Extended-Release Capsules are administered orally once daily. Instruct patients to swallow Tramadol Hydrochloride Extended-Release Capsules capsules whole, and to take it with liquid. Breaking, chewing, splitting, or dissolving Tramadol Hydrochloride Extended-Release Capsules will result in uncontrolled delivery of tramadol and can lead to overdose or death [see Warnings and Precautions (5.1) ] . Tramadol Hydrochloride Extended-Release Capsules may be taken without regard to food. It is recommended that Tramadol Hydrochloride Extended-Release Capsules be taken in a consistent manner [see Clinical Pharmacology (12.3) ] . 2.2 Patient Access to an Opioid Overdose Reversal Agent for the Emergency Treatment of Opioid Overdose Inform patients and caregivers about opioid overdose reversal agents (e.g., naloxone, nalmefene). Discuss the importance of having access to an opioid overdose reversal agent, especially if the patient has risk factors for overdose (e.g., concomitant use of CNS depressants, a history of opioid use disorder, or prior opioid overdose) or if there are household members (including children) or other close contacts at risk for accidental ingestion or opioid overdose. The presence of risk factors for overdose should not prevent the management of pain in any patient [see Warnings and Precautions (5.1 , 5.2 , 5.3) ] . Discuss the options for obtaining an opioid overdose reversal agent (e.g., prescription, over-the-counter, or as part of a community-based program) [see Warnings and Precautions (5.2) ]. There are important differences among the opioid overdose reversal agents, such as route of administration, product strength, approved patient age range, and pharmacokinetics. Be familiar with these differences, as outlined in the approved labeling for those products, prior to recommending or prescribing such an agent. 2.3 Initial Dosage It is safer to underestimate a patient's 24-hour tramadol requirements and provide rescue medication (e.g., immediate-release opioid) than to overestimate the 24-hour tramadol dosage and manage an adverse reaction due to an overdose. While useful tables of opioid equivalents are readily available, there is inter-patient variability in the potency of opioid drugs and opioid formulations. Frequently reevaluate patients for signs and symptoms of opioid withdrawal and for signs of oversedation/toxicity after converting patients to Tramadol Hydrochloride Extended-Release Capsules. Use of Tramadol Hydrochloride Extended-Release Capsules The initial dose of Tramadol Hydrochloride Extended-Release Capsules is 100 mg once daily. Patients Currently on Tramadol Immediate-Release (IR) Products Calculate the 24-hour tramadol IR dose and initiate a total daily dose of Tramadol Hydrochloride Extended-Release Capsules rounded down to the next lowest 100 mg increment. The dose should be taken once daily. The dose may subsequently be individualized according to patient need. Due to limitations in flexibility of dose selection with Tramadol Hydrochloride Extended-Release Capsules, some patients maintained on tramadol IR products may not be able to convert to Tramadol Hydrochloride Extended-Release Capsules. Conversion from Other Opioid Analgesics to Tramadol Hydrochloride Extended-Release Capsules When Tramadol Hydrochloride Extended-Release Capsules therapy is initiated, discontinue all opioid analgesics other than those used on an as needed basis for breakthrough pain when appropriate. There are no established conversion ratios for conversion from other opioids to Tramadol Hydrochloride Extended-Release Capsules defined by clinical trials. Initiate dosing using Tramadol Hydrochloride Extended-Release Capsules 100 mg once a day. 2.4 Titration and Maintenance Therapy Individually titrate Tramadol Hydrochloride Extended-Release Capsules by 100 mg every five days to a dose that provides adequate analgesia and minimizes adverse reactions. The maximum daily dose of Tramadol Hydrochloride Extended-Release Capsules is 300 mg per day. Continually reevaluate patients receiving Tramadol Hydrochloride Extended-Release Capsules to assess the maintenance of pain control, signs and symptoms of opioid withdrawal, and other adverse reactions, as well as to reassess for the development of addiction, abuse, or misuse [see Warnings and Precautions (5.1 , 5.18) ] . Frequent communication is important among the prescriber, other members of the healthcare team, the patient, and the caregiver/family during periods of changing analgesic requirements, including initial titration. During use of opioid therapy for an extended period of time, periodically reassess the continued need for the use of opioid analgesics. Patients who experience breakthrough pain may require a dosage adjustment of Tramadol Hydrochloride Extended-Release Capsules or may need rescue medication with an appropriate dose of an immediate-release analgesic. If the level of pain increases after dosage stabilization, attempt to identify the source of increased pain before increasing the Tramadol Hydrochloride Extended-Release Capsules dosage. If after increasing the dosage, unacceptable opioid-related adverse reactions are observed (including an increase in pain after a dosage increase), consider reducing the dosage [see Warnings and Precautions (5) ] . Adjust the dosage to obtain an appropriate balance between management of pain and opioid-related adverse reactions. 2.5 Safe Reduction or Discontinuation of Tramadol Hydrochloride Extended-Release Capsules Do not rapidly reduce or abruptly discontinue Tramadol Hydrochloride Extended-Release Capsules in patients who may be physically dependent on opioids. Rapid reduction or abrupt discontinuation of opioid analgesics in patients who are physically dependent on opioids has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide. Rapid reduction or abrupt discontinuation has also been associated with attempts to find other sources of opioid analgesics, which may be confused with drug-seeking for abuse. Patients may also attempt to treat their pain or withdrawal symptoms with illicit opioids, such as heroin, and other substances. When a decision has been made to decrease the dose or discontinue therapy in an opioid-dependent patient taking Tramadol Hydrochloride Extended-Release Capsules, there are a variety of factors that should be considered, including the total daily dose of opioid (including Tramadol Hydrochloride Extended-Release Capsules) the patient has been taking, the duration of treatment, the type of pain being treated, and the physical and psychological attributes of the patient. It is important to ensure ongoing care of the patient and to agree on an appropriate tapering schedule and follow-up plan so that patient and provider goals and expectations are clear and realistic. When opioid analgesics are being discontinued due to a suspected substance use disorder, evaluate and treat the patient, or refer for evaluation and treatment of the substance use disorder. Treatment should include evidence-based approaches, such as medication assisted treatment of opioid use disorder. Complex patients with comorbid pain and substance use disorders may benefit from referral to a specialist. There are no standard opioid tapering schedules that are suitable for all patients. Good clinical practice dictates a patient-specific plan to taper the dose of the opioid gradually. For patients on Tramadol Hydrochloride Extended-Release Capsules who are physically opioid-dependent, initiate the taper by a small enough increment (e.g., no greater than 10% to 25% of the total daily dose) to avoid withdrawal symptoms, and proceed with dose-lowering at an interval of every 2 to 4 weeks. Patients who have been taking opioids for briefer periods of time may tolerate a more rapid taper. It may be necessary to provide the patient with lower dosage strengths to accomplish a successful taper. Reassess the patient frequently to manage pain and withdrawal symptoms, should they emerge. Common withdrawal symptoms include restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis. Other signs and symptoms also may develop, including irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate. If withdrawal symptoms arise, it may be necessary to pause the taper for a period of time or raise the dose of the opioid analgesic to the previous dose, and then proceed with a slower taper. In addition, evaluate patients for any changes in mood, emergence of suicidal thoughts, or use of other substances. When managing patients taking opioid analgesics, particularly those who have been treated for an extended period of time and/or with high doses for chronic pain, ensure that a multimodal approach to pain management, including mental health support (if needed), is in place prior to initiating an opioid analgesic taper. A multimodal approach to pain management may optimize the treatment of chronic pain, as well as assist with the successful tapering of the opioid analgesic [see Warnings and Precautions (5.18) , Drug Abuse and Dependence (9.3) ] .

( 5.6 ) The effects of concomitant use or discontinuation of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with tramadol are complex. Use of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with Tramadol Hydrochloride Extended-Release Capsules requires careful consideration of the effects on the parent drug, tramadol, and the active metabolite, M1. ( 5.7 , 7 ) Addiction, Abuse, and Misuse Because the use of Tramadol Hydrochloride Extended-Release Capsules exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death, assess each patient's risk prior to prescribing and reassess all patients regularly for the development of these behaviors and conditions [see Warnings and Precautions (5.1) ] . Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression may occur with use of Tramadol Hydrochloride Extended-Release Capsules, especially during initiation or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of Tramadol Hydrochloride Extended-Release Capsules are essential. Instruct patients to swallow Tramadol Hydrochloride Extended-Release Capsules intact, and not to split, break, chew, crush, or dissolve the contents of the capsules to avoid exposure to a potentially fatal dose of tramadol. [see Dosage and Administration (2.1) , Warnings and Precautions (5.2) ] . Accidental Ingestion Accidental ingestion of even one dose of Tramadol Hydrochloride Extended-Release Capsules, especially by children, can result in a fatal overdose of tramadol [see Warnings and Precautions (5.2) ] . Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of Tramadol Hydrochloride Extended-Release Capsules and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate [see Warnings and Precautions (5.3) , Drug Interactions (7) ] . Neonatal Opioid Withdrawal Syndrome (NOWS) Advise pregnant women using opioids for an extended period of time of the risk of Neonatal Opioid Withdrawal Syndrome, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery [see Warnings and Precautions (5.4) ] . Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS) Healthcare providers are strongly encouraged to complete a REMS-compliant education program and to counsel patients and caregivers on serious risks, safe use, and the importance of reading the Medication Guide with each prescription [see Warnings and Precautions (5.5) ] . Ultra-Rapid Metabolism Of Tramadol And Other Risk Factors for Life-Threatening Respiratory Depression in Children Life-threatening respiratory depression and death have occurred in children who received tramadol. Some of the reported cases occurred following tonsillectomy and/or adenoidectomy, and in at least one case, the child had evidence of being an ultra-rapid metabolizer of tramadol due to a CYP2D6 polymorphism [see Warnings and Precautions (5.6) ] . Tramadol Hydrochloride Extended-Release Capsules are contraindicated in children younger than 12 years of age and in children younger than 18 years of age following tonsillectomy and/or adenoidectomy [see Contraindications (4) ] . Avoid the use of Tramadol Hydrochloride Extended-Release Capsules 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 [see Warnings and Precautions (5.6) ] . Interactions with Drugs Affecting Cytochrome P450 Isoenzymes The effects of concomitant use or discontinuation of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with tramadol are complex. Use of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with Tramadol Hydrochloride Extended-Release Capsules requires careful consideration of the effects on the parent drug, tramadol, and the active metabolite, M1 [see Warnings and Precautions (5.7) , Drug Interactions (7) ] .

Monitoring

  • 5 WARNINGS AND PRECAUTIONS Opioid-Induced Hyperalgesia and Allodynia: Opioid-Induced Hyperalgesia (OIH) occurs when an opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain.
  • If OIH is suspected, carefully consider appropriately decreasing the dose of the current opioid analgesic or opioid rotation.
  • ( 5.8 ) Serotonin Syndrome Risk: Potentially life-threatening condition could result from use of Tramadol Hydrochloride Extended-Release Capsules, particularly during concomitant use of serotonergic drugs.
  • ( 5.9 ) Increased Risk of Seizures: Present within recommended dosage range.

Interaction Notes

  • 7 DRUG INTERACTIONS Table 2 includes clinically significant drug interactions with Tramadol Hydrochloride Extended-Release Capsules.
  • Table 2: Clinically Significant Drug Interactions with Tramadol Hydrochloride Extended-Release Capsules Inhibitors of CYP2D6 Clinical Impact: The concomitant use of Tramadol Hydrochloride Extended-Release Capsules and CYP2D6 inhibitors may result in an increase in the plasma concentration of tramadol and a decrease in the plasma concentration of M1, particularly when an inhibitor is added after a stable dose of Tramadol Hydrochloride Extended-Release Capsules is achieved.
  • Since M1 is a more potent mu-opioid agonist, decreased M1 exposure could result in decreased therapeutic effects, and may result in signs and symptoms of opioid withdrawal in patients who had developed physical dependence to tramadol.
  • Increased tramadol exposure can result in increased or prolonged therapeutic effects and increased risk for serious adverse events including seizures and serotonin syndrome.
