Oxymorphone Generic Name & Formulations
Oxymorphone HCl 5mg, 10mg; immediate-rel tabs.
Management of acute pain severe enough to require an opioid analgesic and for which alternative treatment options are inadequate.
Oxymorphone Dosage and Administration
Use lowest effective dose for shortest duration. Individualize. Take on empty stomach. May give immediate-release (IR) tab as needed on an every 4–6hrs schedule; ext-rel tab is given on a continuous basis every 12hrs. ≥18yrs: Opioid-naive: IR tab: 10–20mg every 4–6hrs as needed. Ext-rel tab: Swallow whole; 5mg every 12hrs, titrate by 5–10mg every 12hrs every 3–7 days; if breakthrough pain occurs: adjust dose or use a small-dose rescue medication (eg, IR oxymorphone). Converting from IR tab to ext-rel tab: Give half the total daily IR tab dose as ext-rel tab every 12hrs. Conversion from other opioids: see full labeling. Mild hepatic impairment, renal impairment (CrCl <50mL/min), or elderly (≥65yrs): opioid-naive: initiate with 5mg dose; opioid-experience: initiate at 50% lower than normal starting dose and titrate slowly. Concomitant other CNS depressants: initiate at ⅓–½ of usual starting dose and monitor. Withdraw gradually (esp. if opioid-dependent), taper by ≤10–25% every 2–4 weeks.
<18yrs: not established.
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. Moderate to severe hepatic impairment.
Oxymorphone Boxed Warnings
Addiction, abuse, and misuse. Risk evaluation and mitigation strategy (REMS). Life-threatening respiratory depression. Accidental ingestion. Neonatal opioid withdrawal syndrome. Interaction with alcohol. Risks from concomitant use with benzodiazepines or other CNS depressants.
Assess the potential need for access to naloxone when initiating and renewing therapy. Consider prescribing naloxone based on risk factors for overdose (eg, history of opioid use disorder, prior opioid overdose, household members or other close contacts at risk for accidental ingestion or overdose). 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). Sleep-related breathing disorders (including central sleep apnea (CSA), sleep-related hypoxemia); consider dose reduction if CSA develops. 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. Drug and alcohol abusers. Renal or hepatic impairment. ER tabs: difficulty in swallowing or at risk for underlying GI disorders (eg, esophageal or colon cancer); consider other analgesics. Reevaluate periodically. Avoid abrupt cessation. Elderly. Cachectic. Debilitated. Pregnancy; potential neonatal opioid withdrawal syndrome during prolonged use. Labor & delivery, nursing mothers: not recommended.
Avoid alcohol or alcohol-containing products. 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 closely; consider prescribing naloxone if concomitant use is warranted. 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, cyclobenzaprine, metaxalone, 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/or precipitate withdrawal symptoms. May antagonize diuretics; monitor. Paralytic ileus may occur with anticholinergics. May be potentiated by cimetidine. May increase serum amylase.
