Indications for PERCODAN:
Management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate.
Use lowest effective dose for shortest duration. Individualize. Initially 1 tab every 6 hrs as needed. Aspirin max daily dose: 4g. Concomitant use or discontinuation of CYP3A4 inhibitors or inducers: monitor closely and consider dose adjustments (see full labeling). Withdraw gradually by 25–50% every 2–4 days.
Significant respiratory depression. Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment. Known or suspected GI obstruction, including paralytic ileus. Hemophilia. Children or teenagers with viral infections, with or without fever, due to risk of Reye syndrome.
Addiction, abuse, and misuse. Risk evaluation and mitigation strategy (REMS). Life-threatening respiratory depression. Accidental ingestion. Neonatal opioid withdrawal syndrome. Cytochrome P450 3A4 interaction. Risks from concomitant use with benzodiazepines or other CNS depressants.
Abuse potential (monitor). 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). COPD, cor pulmonale, decreased respiratory reserve, hypoxia, hypercapnia, or pre-existing respiratory depression; monitor and consider non-opioid analgesics. Adrenal insufficiency. Head injury. Increased intracranial pressure, brain tumors; monitor. Seizure disorders. CNS depression. Impaired consciousness, coma, shock; avoid. Biliary tract disease. Acute pancreatitis. Avoid in peptic ulcer disease. Coagulation abnormalities. Monitor bowel motility in post-op patients. Drug or alcohol abusers. Renal or hepatic impairment; avoid if severe. Reevaluate periodically. Avoid abrupt cessation. Elderly. Cachectic. Debilitated. Pregnancy (avoid during 3rd trimester); potential neonatal opioid withdrawal syndrome during prolonged use. Labor & delivery, nursing mothers: not recommended.
Opioid + salicylate.
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. During or within 14 days of MAOIs: not recommended. 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. Avoid concomitant mixed agonist/antagonist opioids (eg, butorphanol, nalbuphine, pentazocine) or partial agonist (eg, buprenorphine); may reduce effects and precipitate withdrawal symptoms. 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. Increased risk of bleeding with alcohol, anticoagulants, other NSAIDs. May antagonize uricosurics, antihypertensives. May potentiate acetazolamide, oral hypoglycemics, methotrexate.
Lightheadedness, dizziness, drowsiness/sedation, nausea, vomiting, euphoria, dysphoria, constipation, pruritus; respiratory depression, severe hypotension, syncope, hypersensitivity.
