I was a 52 yr. old healthy female and was diagnosed with pneumonia in October of 2002. My doctor prescribed 500 mg Levaquin. It did seem to help with the pneumonia, however while taking it I had the first anxiety and panic attacks I had ever had. Had bouts of crying. Was unable to concentrate, and could not sleep. Since that time, my eyes have been extremely watery and my allergy medication is no help. I am often achy and as of late I am experiencing pain in my right arm near the top. I have very little energy,no interest in seeing friends or doing things I used to enjoy. I have no interest in sex. I think this drug is very dangerous and should be taken off the market.
