A member asked:
How long will an allergic reaction rash from keflex last? i was on the pills for 13 days before the dr finally said it was an allergic reaction
A doctor has provided 1 answer
Days to weeks: Can last days to weeks. Itching usually goes away within a week. But lesions from rash can last several weeks before they completely fade.
