Summary
Procarbazine has MAO-inhibiting properties, so combining it with venlafaxine may cause serotonin syndrome or hypertensive reactions. Evidence is mostly extrapolated from MAOI class effects.
What this interaction means in plain words
Procarbazine and Venlafaxine 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.
Procarbazine belongs to Oncology; Venlafaxine belongs to Central Nervous System.
Why it happens
Weak MAO inhibition by procarbazine adds to venlafaxine's serotonin and noradrenaline reuptake inhibition.
What to do
Avoid the combination and allow at least 14 days after stopping procarbazine before starting venlafaxine. Use a non-serotonergic alternative if an antidepressant is needed.
