Summary
Selegiline is a MAO-B inhibitor that loses selectivity at higher doses and, together with a tricyclic-type antidepressant such as amoxapine, can precipitate serotonin syndrome or hypertensive reactions. Labeling for both drug classes advises against concurrent use.
What this interaction means in plain words
Amoxapine and Selegiline 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.
Why it happens
Combined MAO inhibition and inhibition of norepinephrine and serotonin reuptake, causing excess monoaminergic activity.
What to do
Do not co-administer; allow at least 14 days between stopping selegiline and starting amoxapine, and an adequate washout in the other direction. Seek urgent care for agitation, hyperthermia, tremor or severe hypertension.
