tonsillitis/pharyngitis
"After 3 days of taking this medication I was suffering from constant gastrointestinal issues, which is something I have never experienced on antibiotics before even with probiotics. On day 4 I began with severe itching, burning, and hives and returned to the doctor. This antibiotic also seemed to have little affect on my original illness. I am now on a Z pack and feel much better. Now I have to be on a long course of Prednisone for my allergic reaction which has yet to subside. This by far has been the worst antibiotic I have ever taken in my life. Never ever again!"
