Last updated
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
Amoxapine blocks reuptake of norepinephrine and serotonin, and tranylcypromine is an irreversible nonselective MAOI. Together they can cause serotonin syndrome or hypertensive crisis.
What this interaction means in plain words
Amoxapine 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.
Why it happens
Reuptake inhibition combined with irreversible MAO inhibition increases synaptic serotonin and norepinephrine.
What to do
Do not combine. Observe a washout of at least 14 days after stopping tranylcypromine before starting amoxapine, and an adequate washout of amoxapine before starting an MAOI.
