Summary
Dexamethasone is a mild to moderate CYP3A4 inducer and may reduce zaleplon exposure. Because CYP3A4 is a secondary pathway, a clinically important loss of effect is unlikely.
What this interaction means in plain words
Dexamethasone and Zaleplon have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Dexamethasone belongs to Endocrine; Zaleplon belongs to Central Nervous System.
Why it happens
CYP3A4 induction by dexamethasone increases the secondary oxidative metabolism of zaleplon.
What to do
No adjustment is needed routinely; reassess hypnotic efficacy if the patient is on prolonged or high-dose dexamethasone.

- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
