I was prescribed Cipro because I had bleeding in my seman and the Urologist could not find out any reason, even after surgery. I almost immediatly could not get out of bed because my back and left sholder hurt so much. I did not relate it to Cipro until later when I was looking up something else on the internet and stumbled onto a site that listed problems with the fluoroquinolone class of anti biotics. I have spent time researching the subject and have been taking it really easy and am getting better. I still have the bleeding (almot three months now) and now will tell doctors that I am alergic to Prozak AND Cipro.
