Had a sinus infection that was not responding to other antibiotics. Took a levaquin 750 at 5:30 this AM got up for work at 6:30 and was extremely dizzy, had a major headache and also thought that I was going to vomit. Incredible stomach pain, this lasted until 3:30 today. I was in bed most of the day. My doctor switched to a different antibiotic again. It is a shame that there are all of these awful side effects as the drug works so well ridding the body of infections. I won't take this drug again.
