Reply #6: One unusual side effect I experienced on Cipro: tendinitis.

[megatherium]

I took Cipro for nearly a year about 10 years ago, to get rid of a chronic prostate infection. About 10 months into the course of Cipro, my left arm and shoulder tendons got sore and tender. At first, I thought I'd strained myself in a workout, perhaps over-doing it stretching before a run. But it didn't get better, it was getting worse. Then I happened to read on the internet about this problem with Cipro. Apparently it is a fairly rare side effect, it hadn't cropped up in phase three trials. So several weeks before I was supposed to stop taking the stuff, I stopped taking it. I mentioned all of this to my urologist -- he was surprised, he'd only gotten informed about this a week or two earlier. Once I stopped the Cipro, my tendinitis resolved. And fortunately, the prostate infection never came back.
