I was prescribed this drug on a Wednesday for a sinus infection. By Saturday I could not stand up, was disoriented, dizzy, fatigued, and in general felt like crap. I did not take one on Sunday. I went back to the Doctor on Monday who told me I had fluid on my ear and that was why I was having those symptoms and it was not the medication. He gave me another round which I took around 3:00 p.m. on Monday. By 10:00 p.m. I had the dry heaves, could not stand up, was extremely dizzy, nauseated, fatigued again. I did not sleep any on Monday night. Tuesday morning I flushed remaining drug down the toilet. I has taken me 4 weeks to get to feeling some better. But, for the past several days, I have been having a crushing pain in my chest and upper body. I'm convinced it was from the Avelox. Something needs to be done to get this stuff off the market. I will never take this stuff again.
