irritable bowel syndrome
"AWFUL MEDICATION. I was on Xifaxan for a week and a half when it started giving me crippling stomach cramps every time I ate. The cramps have persisted three weeks beyond stopping the medication and I can only eat plain rice/pasta and peas. It also didn't do what it was prescribed to do and I still have symptoms of IBS. All it did was give me a side effect that makes me not able to eat."
