Starting taking Levaquin 06.14.03. I have a sever rash on both arms and legs. Was not told it was sensitive to sun. I also have a metallic taste in my mouth. I started getting the rash immediately after taking my first dose on 06.14.03. The metallic taste yesterday 06.17. I also can't sleep and have no appetite. My dr. prescribed it for a UTI. I will call them as soon as they open. I, too will start looking up side effects before I take any medicine. Benadryl does help but I can't take it at work because it makes me sleepy. Thanks, Robyn
