Q: How long does it take for fever to subside after stopping offending agent in "Drug Induced Fever"?
Answer: About 72 hours
Fever does not subside instantly after stopping drug in suspected drug induced fever. It may take 48-96 hours, and may persist for weeks if other manifestations of hypersensitivity accompany the fever, such as a maculopapular rash. Other causes of persistent fever despite discontinuation of offending drug is slow elimination rate.
