tonsillitis/pharyngitis
"I was diagnosed with strep throat a few days ago and was prescribed zpak because of a penicillin allergy. I took two pills on the first day, and felt better within 24 hours. The only downside to this medicine is when I took the first dose (2 pills, 500mg total) I had HORRIBLE sharp pains from what was gas followed by diarrhea within 2 hours. The next day I took one pill, and had no side effects. I am on my third day and had pains, similar to harsh period cramps and then diarrhea also within two hours. I find it helpful to eat greek yogurt before taking this medicine! It helps ease the pain and I did not have loose stools on the days I ate the yogurt. Overall this medicine is great because it works extremely fast"
