Zelnorm

What is Zelnorm

Zelnorm increases the action of serotonin (a body chemical) in the intestines. This speeds the movement of stools (bowel movements) through the bowels.

Zelnorm is used to treat severe, chronic, irritable bowel syndrome (IBS) in women who have constipation as their main bowel problem (constipation-predominant). Zelnorm has not been shown to be helpful for men with irritable bowel syndrome.

Zelnorm may also be used for purposes other than those listed in this medication guide.

In studies, patients receiving Zelnorm had more abdominal surgery than patients receiving sugar pills. However, it is not known if Zelnorm will increase the risk of abdominal surgery. If you suddenly get different or worse abdominal pain, contact your doctor.
