sinusitis
"I was prescribed 500 mg twice a day Augmentin for a sinus infection. After the second dose I developed BAD stomach cramps, nausea and loose stools.  I continued the Augmentin for three more days but finally had to stop taking it due to the fact that it was completely destroying my stomach. It was working wonders on my sinus infection but the side effects were too much to bear. Worst of all, I'm still having cramps and loose stools even though I stopped taking the Augmentin two days ago. I hope the issues resolve themselves soon and won't require a trip to my gastroenerologist.  Augmentin may be fine for some people but it's definitely NOT for me!"
