Summary
Opioids given with MAO inhibitors have been associated with serious reactions, including hypotension, CNS depression and in some cases serotonin-like toxicity with hyperthermia. Labeling advises against use during or within 14 days of MAOI therapy.
What this interaction means in plain words
Oxymorphone and Tranylcypromine 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.
Oxymorphone belongs to Musculoskeletal; Tranylcypromine belongs to Central Nervous System.
Why it happens
MAO inhibition potentiates opioid CNS effects and may cause serotonergic or autonomic toxicity; the exact mechanism varies by opioid.
What to do
Do not use oxymorphone during or within 14 days after stopping tranylcypromine. Choose an alternative analgesic.
