irritable bowel syndrome
"I have dealt with severe flare ups from Irritable Bowel Syndrome for almost 3 years and the combination of Bentyl, Donnatal and when very bad, Lomotil, work together like a charm.  Donnatal is my go-to medicine, but Bentyl does what it is suppose to do which is to help with the cramping and pain associated with flare ups.  ZERO side effects at 40-60mg a day.  Good medicine."
