How quickly can clindamycin clear a case of strep throat?

Quickly: You should start to feel better within a day or so. Remember to take all of your antibiotics, or your infection can come back and not respond to future antibiotic treatment.

Depends: Not the first choice in treatment of strep, unless allergic to penicillin. If the person is relatively healthy and antibiotics are taken properly the infection should clear up in about a week.

Fast improvement: Clindamycin works quickly but i would stay on a 10 day course to clear.
