Applies to celecoxib / tramadol: oral tablet.


Oral route (Tablet)

Addiction, Abuse, and MisuseCelecoxib/traMADol exposes patients and other users to the risk of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk prior to prescribing celecoxib/traMADol and monitor all patients regularly for the development of these behaviors and conditions.Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS)To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a REMS for these products. Under the requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers. Healthcare providers are strongly encouraged to: complete a REMS-compliant education program, counsel patients and/or caregivers, with every prescription, on safe use, serious risks, storage, and disposal of these products, emphasize to patients and their caregivers the importance of reading the Medication Guide every time it is provided by their pharmacist, and consider other tools to improve patient, household, and community safety.Life-Threatening Respiratory DepressionSerious, life-threatening, or fatal respiratory depression may occur with use of celecoxib/traMADol. Monitor for respiratory depression, especially during initiation of celecoxib/traMADol.Accidental IngestionAccidental ingestion of even one dose celecoxib/traMADol, especially by children, can be fatal.Cardiovascular Thrombotic EventsNonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction, and stroke, which can be fatal. This risk may occur early in the treatment and may increase with duration of use.Celecoxib/traMADol is contraindicated in the setting of coronary artery bypass graft (CABG) surgery.Gastrointestinal Bleeding, Ulceration, and PerforationNSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious (GI) events.Ultra-Rapid Metabolism of TraMADol and Other Risk Factors for Life-Threatening Respiratory Depression in ChildrenLife-threatening respiratory depression and death have occurred in children who received traMADol. Some of the reported cases followed tonsillectomy and/or adenoidectomy; in at lease one case, the child had evidence of being an ultra-rapid metabolizer of traMADol due to a CYP2D6 polymorphism. Celecoxib/traMADol is contraindicated in children younger than 12 years of age an in children younger than 18 years of age following tonsillectomy and/or adenoidectomy. Avoid use of celecoxib/traMADol 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.Neonatal Opioid Withdrawal SyndromeProlonged use of celecoxib/traMADol during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.Interactions with Drugs Affecting Cytochrome P450 IsoenzymesThe effects of concomitant use or discontinuation of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with traMADol are complex. Use of cytochrome P450 P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with celecoxib/traMADol requires careful consideration of the effects on the parent drug, traMADol, and the active metabolite, M1.Risks from Concomitant Use with Benzodiazepines or Other CNS DepressantsConcomitant 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 celecoxib/traMADol and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate.Limit treatment to the minimum duration.Follow patients for signs and symptoms of respiratory depression and sedation.
