1 Antibiotics help treat your strep throat. You should feel better within 2 to 3 days after you start antibiotics.  Take your medicine as directed. Call your healthcare provider if you think your medicine is not helping or if you have side effects.
My D's strep throat that would not go away with antibiotics (diagnosed the same way - no tests) turned out to be mono, later confirmed by a blood test. As someone with a huge personal strep throat experience, I'd say antibiotics should start showing their effect after 24 hours.
