Last updated
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
MAO inhibitors given with opioids can cause serotonin syndrome or unpredictable opioid toxicity, including respiratory depression and coma. The risk persists for about two weeks after the MAOI is stopped.
What this interaction means in plain words
Hydrocodone and Isocarboxazid are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Hydrocodone belongs to Musculoskeletal; Isocarboxazid belongs to Central Nervous System.
Why it happens
Nonselective MAO inhibition raises serotonergic and noradrenergic activity and may alter opioid effects, causing serotonin toxicity or CNS depression.
What to do
Do not use hydrocodone during or within 14 days of an MAOI; choose a non-opioid or non-interacting analgesic. If an opioid is unavoidable, use closely monitored small test doses.
