Nitrofurantoin
"I normally get UTI All the time, I also suffer from Interstitial cystitis (IC) of the bladder, so it's hard to tell when I have a UTI or just a flare from my IC. I saw my Dr. Last week, and I had some burning, So I figured might as well get my urine checked, came back I have a UTI, my Dr. Called in antibitic, I assumed it would be Levaquin that's the one I have always gotten, really the only one that I get no side effects, will only take that or cipro, so when hubby came back with macrobid, I emailed my Dr. Thinking he forgot, he said the kind of UTI I have Levaquin will not work on it, I am on 4th day 2xday no side effects but still burning & pressure!so not sure if it is working."
