Summary
Etravirine is a modest inducer of CYP3A4 and may lower zaleplon exposure. Zaleplon is cleared mainly by aldehyde oxidase with a smaller CYP3A4 contribution, so any loss of hypnotic effect is likely to be small.
What this interaction means in plain words
Etravirine 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.
Etravirine belongs to Anti Virals; Zaleplon belongs to Central Nervous System.
Why it happens
Etravirine weakly induces CYP3A4, slightly increasing the minor oxidative clearance of zaleplon.
What to do
No dose change is usually needed; reassess sleep response if the patient reports reduced hypnotic effect.
What to ask your pharmacist
- Is there anything I should notice while taking both?
