Indication

MARPLAN (isocarboxazid) is a monoamine oxidase inhibitor (MAOI) indicated for the treatment of depression. Because of its potentially serious side-effect profile, MARPLAN should be used in patients who have not responded to other antidepressant therapy.

Contraindications

MARPLAN should NOT be administered to patients with:

  • Known hypersensitivity to isocarboxazid
  • Confirmed or suspected cerebrovascular defect
  • Cardiovascular disease or hypertension
  • History of headache
  • Pheochromocytoma
  • History of liver disease or abnormal liver function tests
  • Severe renal impairment
  • Pediatric patients (<16 years)

MARPLAN should not be used in combination with: other MAO inhibitors or dibenzazepine derivatives; sympathomimetics (including amphetamines); CNS depressants (including narcotics and alcohol); antihypertensive, diuretic, antihistaminic, sedative, or anesthetic drugs; bupropion HCl; buspirone HCl; dextromethorphan; tyramine-rich foods (e.g., aged cheeses); or excessive quantities of caffeine.

Warnings & Precautions

  • Hypertensive Crisis: The most serious reaction involves hypertensive crises (severe headache, nausea, vomiting, tachycardia) precipitated by ingestion of tyramine-containing foods or co-administration of sympathomimetic agents or certain other drugs. Potentially fatal outcomes have been reported.
  • Serotonin Syndrome: Risk with concomitant serotonergic drugs.
  • Hypotension: Orthostatic hypotension may occur; caution in patients with known cardiovascular disease.
  • Lower Seizure Threshold: Use with caution in patients with a history of epilepsy.
  • Hepatotoxicity: May cause altered liver function or jaundice. Periodic liver chemistry tests should be performed; discontinue at first sign of hepatic dysfunction.
  • Activation of Mania/Hypomania: Screen patients for bipolar disorder before initiating treatment.
  • Drug Interactions: MAO inhibitory effects may persist for a substantial period after discontinuation. Allow at least 10 days after stopping MARPLAN before initiating another therapy. Allow at least 1 week medication-free interval when switching from another MAOI or dibenzazepine-related entity to MARPLAN.
  • Pregnancy & Lactation: It is not known whether isocarboxazid can cause embryo-fetal harm. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185.
