I wish that I had found this site before taking Levaquin 750. My local hospital ER perscribed Levaquin for my bout of Pneumonia. The Levaquin did little for the bacteria but started a rash which has turned into Varicella, I'm told. While taking Levaquin for only five days, I could barely walk, had constant bowl movements, joint pain and now being left covered with a red rash. Doesn't the FDA screen these powerful new drugs?
