I heard this antibiotic is hard on the intestines and can cause c.diff and UC flares. I am not a Dr but this is what I have read. I have taken it in the past, before I had UC. I often wonder if it wiped out my good flora and made me more susceptible to UC.
I am always trying to link up any possible things that could have caused UC but the truth is that I was probably predisposed to it from geneitcs. No one in my family has this illness as far as I know but maybe I am the first or maybe a distant relative had it and I don't know.
