Summary
Both drugs have serotonergic activity, so combining them could theoretically increase the risk of serotonin syndrome. Amoxapine is a weaker serotonin reuptake inhibitor than many antidepressants, so the risk is probably modest.
What this interaction means in plain words
Amoxapine and Buspirone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive serotonergic effects from 5-HT1A partial agonism and reuptake inhibition.
What to do
Monitor for agitation, tremor, hyperreflexia, sweating and fever after starting or raising doses. Stop one agent if serotonin syndrome is suspected.
