A member asked:

How much time does strep throat/tonsillitis last while on penicillin?

A doctor has provided 1 answer

24 -48 hrs: You usually feel better in 24 -48 hrs ( usually you are on the medication for 7 - 10 days). If you still feel ill, I would contacted your doctor. Could be strep that is resistant to penicillin or a more serious strep infection.
