OMG! I started taking Levaquin 500mg yesterday for a severe kidney infection. I think I was giving a shot of it at the doctor's office and then sent home with samples for 7 days. All day after recieving the shot and taking one tablet I had intolerable sweats. If I just got up to do the least little thing I would pour the sweat. Not to mention everytime I would lay down to take a nap I would wake up with soaking wet clothes. I still feel very nauseated even after taking a topical Phenagran (?Spell?) I feel very very dizzy and light headed and my heart seems to do a little quiver every few minutes. Mind you, I am only 21. After reading all of these horrific stories I too will call the doctor immediately and get off of this medication!!!
