What are possible side effects of Linzess?

Linzess (linaclotide), a prescription medication used to treat adults with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC) -- chronic constipation that has no clear cause -- is known to sometimes cause side effects. The most common side effect is diarrhea, which can be severe. Usually, diarrhea will start during the first two weeks of taking Linzess. If you have severe diarrhea while taking Linzess, stop taking it and call your doctor. Other typical side effects of Linzess include gas, pain in your stomach and feeling pressure or swelling in your abdomen.

If you have unusual or severe stomach pain, or if you have red blood in your bowel movements or black, tarry bowel movements, call your doctor or go to the emergency room immediately.

Notify your doctor if you have any side effect that is bothersome or that doesn't go away.
