I was put on the antibiotic avelox for a severe case of pneumonia. Right away I began to feel better.2 days later i began itching everywhere, urinating every half hr to an hr,headaches,dizzy spells,vomiting.Everyday the symptoms are getting worse. The itching is so bad I cant sleep as well as having to get up every hr to pee. During the day I cant keep my eyes open, and go lay down only to itch even worse and never fall asleep.I cant hold any food down and feel totally wiped out all day. Is this normal or am I heading for big medical problems. I stopped the antibiotic on my own today as I am scared that my kidneys or liver are shutting down. I am still very itchy, tired but I am able to eat again.I had another 4 days left on the antibiotic. What is the risk of using this antibiotic or stopping it all together even though I was told that my pneumonia was so severe that would proberly end up in the hospital for it. I also have crohns disease and very little immune system.
