Important Safety Information
AMITIZA (lubiprostone) 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.
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.
AMITIZA has not been studied in pregnant women. Based on animal studies, AMITIZA may cause fetal harm. AMITIZA should only be used during pregnancy if the potential benefits justify the potential risk to the fetus. If you are pregnant or become pregnant while being treated with AMITIZA, talk to your healthcare provider to evaluate the risks to the fetus. Tell your doctor if you are nursing and monitor infants for diarrhea.
Tell your doctor if you have liver problems.
