I can't believe I am reading all these side effects. I only had one problem and I am not sure if it has anything to do with Levaquin. I was in the sun for a few hours and I burned my nose, arms and feet. I was the only one that had a problem with the sun that day. The sunburn was a little blistery so I thought it was some type of sun poisoning. I was OK in a few days. Other then that I had absolutely no side effects. I was on vacation in Italy at the time I took the medication so thankfully I was great. I only took 6 500mg tablets because my pharmacy short changed me one. Maybe it was a good thing.
