A member asked:

Tested positive for strep throat. taking 500 mg penicillin vk for 24 hrs. throat still hurting and still feel bad. how long should it take to work?

A doctor has provided 1 answer

48-72 hours: Many people begin to feel relief from Strep throat symptoms after 24 hours of appropriate antibiotic therapy, but one wouldn't necessarily consider your regiment a treatment failure until you have been taking it for at least 2-3 days. Best wishes.
