Amitiza is a prescription medication used to treat irritable bowel syndrome (IBS) in women and chronic idiopathic constipation in men and women. It is also used to treat opioid-induced constipation (OIC). Amitiza belongs to a group of drugs called CIC-2 chloride channel activators, which increase fluid secretions in the bowel to stimulate the movement of stool. Amitiza comes in capsule form and is usually taken twice daily with food and water. The capsule should be swallowed whole, not chewed or broken.
Common side effects include nausea, diarrhea, and headache.
