Be aware that not having a reaction the first time(s) you take fluoroquinolones is no guarantee that it won't happen later. I had had several exposures to levofloxacin (a very bad ear infection) and ciprofloxacin (post-surgery prophylaxis) several years apart and was fine. A few months after that latter exposure, I took one dose of levofloxacin for an apparent infection, and within less than a day I started experiencing pain in one and then the other ankle. It was very painful to walk for about a month, my ankles were creaky and sore, and there was transitory soreness in my wrists as well. The acute pain subsided after that month but it took about five months total before my ankles were completely pain-free. Don't use these antibiotics except to treat something that will kill you otherwise.
