Patient Education

Alosetron


Alosetron is used to treat diarrhea, pain, cramps, and the feeling of an urgent need to have bowel movements caused by irritable bowel syndrome (IBS; a condition that causes stomach pain, bloating, constipation, and diarrhea) in women who have diarrhea as their main symptom and have not been helped by other treatments. Alosetron is in a class of medications called 5-HT3 receptor antagonists. Alosetron works by slowing the movement of stool (bowel movements) through the intestines.
