How AMITIZA Works

AMITIZA Is Different

AMITIZA is a different kind of Irritable Bowel Syndrome with Constipation (IBS-C) treatment, called a ClC-2 chloride channel activator. AMITIZA works by promoting fluid secretion in the intestine, thereby facilitating bowel movements.

How AMITIZA Works

Step 1

Fluid is used by the intestines to pass waste through the bowels. When there is not enough fluid, constipation can occur.


Indication

AMITIZA (8 mcg) twice daily is approved to treat Irritable Bowel Syndrome with Constipation (IBS-C) in women 18 years of age and older.

Important Safety Information

AMITIZA is not for everyone. If you know or suspect you have a bowel blockage, do not take AMITIZA. If you are unsure, your healthcare provider should evaluate your condition before starting AMITIZA. You should not take AMITIZA if you have severe diarrhea.

AMITIZA has not been studied in pregnant women and should only be used during a pregnancy if the potential benefits justify the potential risk to the fetus. Women should have a negative pregnancy test before beginning treatment with AMITIZA and need to practice effective birth control measures. If you are pregnant or become pregnant while being treated with AMITIZA, talk to your healthcare provider to evaluate the risks to the fetus.

Some patients taking AMITIZA may experience nausea or diarrhea. If nausea occurs, take AMITIZA with food. If your nausea or diarrhea becomes severe, tell your healthcare provider.

Within an hour of taking AMITIZA, a sensation of chest tightness and shortness of breath may occur. These symptoms usually go away within three hours, but may recur with repeated use. Tell your healthcare provider if you experience these symptoms.

The most common side effects of taking AMITIZA (8 mcg) twice daily, pink capsules for IBS-C are nausea, diarrhea, and abdominal pain. These are not all the side effects associated with AMITIZA.

Tell your doctor if you have liver problems.
