Amoxicillin / clavulanate
"I was prescribed augmentin for a dental infection/tooth abscess. When I went to the dentist, I had already been on 3 or 4 days of penicillin. The penicillin didn't seem to be clearing the infection, and the dentist couldn't get me in for a root canal for another week. There the augmentin came into play. The first dose I took on an empty stomach (couldn't eat with my throbbing face). So I had some nausea and just figured it normal. The next dose I took with food, as directed. I puked viciously. I took another dose or two and had similar results... so much nausea and vomiting, it was hard to appreciate the fact my face wasn't throbbing. So it works well on infections, hard on the stomach though."
