Morphine Sulfate Ext-rel Caps Indications


Management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatments are inadequate.

Limitations of Use

Not for use as an as-needed (prn) analgesic. Use only if alternative treatment options (eg, non-opioid analgesics, immediate-release opioids) are ineffective, not tolerated, or otherwise inadequate to provide sufficient management of pain.

Morphine Sulfate Ext-rel Caps Dosage and Administration


Use lowest effective dose for shortest duration. Swallow whole or may sprinkle contents on applesauce. May be given through 16 French gastrostomy tube. Do not give via NG tube. Individualize. May be given on 24hr or 12hr schedule. Usually not for initial therapy; begin with an immediate-release product and convert to an ext-rel product. Opioid non-tolerant: initially 30mg every 24hrs. Adjust dose at 1–2 day intervals. Use 100mg or 200mg caps, a single dose >60mg, or a total daily dose >120mg in opioid-tolerant patients only. Renal failure, cirrhosis: initiate at lower dose; titrate slowly and monitor. Conversion from other morphine formulations or other opioids: see full labeling. Withdraw gradually (esp. if opioid-dependent), taper by ≤10–25% every 2–4 weeks.


<18yrs: not established.

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.

Morphine Sulfate Ext-rel Caps Interactions


See Contraindications. 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. 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, P-gp inhibitors; monitor. May increase serum amylase.
