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

Papaveretum contains morphine and other opium alkaloids, and combining it with a nonselective MAOI can precipitate severe reactions. These include serotonin-like toxicity with hyperthermia and agitation, or marked CNS and respiratory depression with hypotension. Fatalities have been described with MAOI-opioid combinations.

What this interaction means in plain words

Papaveretum and Tranylcypromine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Evidence level: Moderate

Why it happens

MAO inhibition may potentiate opioid and serotonergic effects; the precise mechanism is not fully established.

What to do

Avoid papaveretum during tranylcypromine therapy and for 14 days after discontinuation. Use an alternative analgesic and monitor closely if an opioid cannot be avoided.

What to ask your pharmacist

  • Does the benefit of taking both outweigh the risk in my case?
