Last updated

Summary
Nonselective MAO inhibition prevents breakdown of dopamine and noradrenaline formed from levodopa. This can cause hypertensive crisis, flushing, and severe headache.
What this interaction means in plain words
Levodopa and Procarbazine 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.
Levodopa belongs to Central Nervous System; Procarbazine belongs to Oncology.
Why it happens
MAO inhibition lets catecholamines derived from levodopa accumulate, producing an exaggerated pressor response.
What to do
Avoid concurrent use and keep a washout interval of at least 14 days after stopping procarbazine. If a Parkinson's patient needs procarbazine, review options with the oncology and neurology teams.
