I was prescribed Cipro for an upper respiratory infection in Oct., 2001. Within two days, I suffered nausea and explosive diarrhea. I was sent to the ER and admitted to Edward White Hospital in St. Pete, FL with Clostridium Difficle (C-Diff) caused by the Cipro. The only thing that eventually cured it was six weeks of Vancomycin. I also suffered tendonitis.
