Last year I'd a UTI and well, you got it! I got the CIPRO! Even tho it's in my 'file' that I shouldn't? DUH.. I did ask THREE times, ARE YOU SURE?????
Well, at times better the devil you know than the one you don't? I was on a short course as well, and did just fine until about 10 days after I went off the CIPRO...then PN [new?] kicked in. But not too badly. At least no more infection!
Alternative anti-b's take longer and are less likely to work. The tradeoff is getting rid of the infection and then dealing w/the consequences later. In my own case the CIPRO induced effects have long receded into the background after several months.
The infection could create far more undesirable consequences in the long term if not treated than dealing with the consequences of the treatments.
Mrs D is again, right, in that we have to be super careful with some things. Plain and simple. It's a frustrating place to be in at times, but we are here and must deal with it all! Hugs and hope always
