Tramadol Hcl Ext-rel Tabs Warnings/Precautions


Life-threatening respiratory depression; monitor within first 24–72hrs of initiating therapy and following dose increases. Accidental exposure may cause fatal overdose (esp. in children). Risk of life-threatening respiratory depression and death related to ultra-rapid metabolizers of tramadol (esp. in children for post-tonsillectomy and/or adenoidectomy pain). Avoid in adolescents 12–18yrs with conditions associated with hypoventilation (eg, post-op status, obstructive sleep apnea, obesity, severe pulmonary disease, neuromuscular disease, concomitant drugs that cause respiratory depression). COPD, cor pulmonale, decreased respiratory reserve, hypoxia, hypercapnia, or pre-existing respiratory depression; monitor and consider non-opioid analgesics. Abuse potential (monitor). Adrenal insufficiency. Head injury. Increased intracranial pressure, brain tumors; monitor. Seizure disorders. Avoid in depressed, suicidal, or addiction-prone patients; consider non-narcotic analgesics. Emotional disturbance. CNS depression. Impaired consciousness, coma, shock; avoid. Biliary tract disease. Acute pancreatitis. Drug abusers. Severe hepatic (Child-Pugh Class C) or renal impairment (CrCl<30mL/min): not recommended. Ultra-rapid metabolizers (due to CYP2D6 polymorphism): avoid. Reevaluate periodically. Avoid abrupt cessation. Elderly (esp. >75yrs). Cachectic. Debilitated. Pregnancy; potential neonatal opioid withdrawal syndrome during prolonged use. Labor & delivery, nursing mothers: not recommended.

Tramadol Hcl Ext-rel Tabs Interactions


Concomitant other forms of tramadol or carbamazepine: not recommended. Increased risk of hypotension, respiratory depression, sedation with benzodiazepines or other CNS depressants (eg, non-benzodiazepine sedatives/hypnotics, anxiolytics, general anesthetics, phenothiazines, tranquilizers, muscle relaxants, antipsychotics, alcohol, other opioids); reserve concomitant use in those for whom alternative options are inadequate; limit dosages/durations to minimum required; monitor. Risk of serotonin syndrome with serotonergic drugs (eg, SSRIs, SNRIs, TCAs, triptans, 5-HT3 antagonists, mirtazapine, trazodone, tramadol, MAOIs, linezolid, IV methylene blue); monitor and discontinue if suspected. Increased risk of seizures with SSRIs, SNRIs, anorectics, TCAs, cyclobenzaprine, promethazine, other opioids, MAOIs, naloxone, neuroleptics, and others that lower seizure threshold. Avoid concomitant mixed agonist/antagonist opioids (eg, butorphanol, nalbuphine, pentazocine) or partial agonist (eg, buprenorphine); may reduce effects and precipitate withdrawal symptoms. May be affected by CYP2D6 inhibitors (eg, amiodarone, quinidine, fluoxetine, paroxetine, bupropion). Potentiated by CYP3A4 inhibitors (eg, macrolides, azole antifungals, protease inhibitors). Antagonized by CYP3A4 inducers (eg, rifampin, carbamazepine, phenytoin). May antagonize diuretics; monitor. Paralytic ileus may occur with anticholinergics. Monitor digoxin, warfarin.
