I had tonsillitis two months ago. my first zpack seemed to clear things up quickly but my symptoms returned about two weeks later. after waiting it out another week, i was put on a second zpack which took care of the sore throat but not the swollen tonsil

Recurrent tonsilitis: Could bereflux or recurrent infections. Could try prevecid/ and ranitidine for reflux, elevate head of bed , Avoid caffeine ,smoking alcohol, sodas energy drinks Would see ENT to diagnosis reflux or need for taking the tonsils out due to recurrent infections - sometimes the bacteria get into the crypts and can't be elminated. or may have abscess/ or need clindamycin

See below: Assuming that you did have a strep throat, Z-pak may not have been effective because of the emerging resistance of GAS to Zithromax.Re-treatment for a swollen tonsil isn't indicated unless a peritonsillar abscess is suspected. Statistics show that in the U.S. the risk of Rheumatic Fever is so low that the risk of severe side effects from antibiotics outweighs the risk of not taking the antibiotic.
