Summary

Cyproheptadine blocks 5-HT2A receptors and may reduce the therapeutic effect of SSRIs such as escitalopram. Cases of reduced antidepressant response or return of symptoms have been described with related SSRIs.

What this interaction means in plain words

Cyproheptadine and Escitalopram 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.

Cyproheptadine belongs to Respiratory; Escitalopram belongs to Central Nervous System.

Evidence level: Low

Why it happens

Pharmacodynamic antagonism of serotonin receptors by cyproheptadine counteracts SSRI-mediated serotonergic effects.

What to do

Monitor mood and anxiety symptoms when cyproheptadine is used for more than a short course. Consider an alternative antihistamine or adjust the antidepressant if response worsens.
