I'm taking a 5 day prescription for Zithromax, but I'm getting awful side effects from it. I have a sinus infection. The side effects are stomach pains and diarrhea every day, plus an awful, sickening taste in my mouth that won't go away. I've taken it for 4 days now, I only have one pill left, but WOW....I'll definitely know next time this is prescribed for me not to take it. The side effects are almost as bad, or worse, as the illness it was prescribed for. Anyone else have these side effects on Zithromax?

Thanks Nancy, I hope so too. It's SO weird! And the worst thing is, I don't think it cleared up my sinus infection. I just finished taking it and I still have some symptoms! I'm hoping that since Zithromax supposedly stays in your system for 5 more days after you finish taking it, that it will help some more.
