Summary
Nafcillin is a CYP3A4 inducer and may modestly lower escitalopram levels. The effect is probably small because escitalopram has several metabolic pathways, and nafcillin courses are usually short.
What this interaction means in plain words
Escitalopram and Nafcillin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Induction of CYP3A4 by nafcillin increases escitalopram metabolism.
