Ciprofloxacin
"I have been having recurrent UTIs for about two years. Most recently was prescribed 500 mg Cipro twice a day for 10 days. The first few days it made me very nauseous and dizzy and it didn't matter if I took it with food or not. It's also given me bad heartburn and gas pretty much constantly. I'm on my eighth day and I've noticed some of my UTI symptoms will pop up again randomly but then go away again. Seems to be an effective med for some but I may end up having to try something else."
