Important Safety Information about XIFAXAN 550 mg

XIFAXAN® (rifaximin) 550 mg tablets are not for everyone. Do not take XIFAXAN if you have a known hypersensitivity to rifaximin or any of the components in XIFAXAN.

XIFAXAN, like nearly all antibiotics, can alter the normal bacteria of the colon. This can lead to an overgrowth of Clostridium difficile (C. difficile) bacteria. If you take XIFAXAN, there is a chance you could experience diarrhea caused by C. difficile. C. difficile can cause symptoms ranging in severity from mild diarrhea to fatal colitis. If you suspect you have C. difficile–associated diarrhea, contact your healthcare provider immediately, as treatment may need to be discontinued.

XIFAXAN has not been studied in people with MELD scores over 25 and only 8.6% of people in the controlled study had MELD scores over 19. There is an increased chance that XIFAXAN will spread through your body if you have more severe hepatic dysfunction. Therefore, if you have severe hepatic impairment, which is a Child-Pugh score of C, you should talk to your healthcare provider before taking XIFAXAN.

If you are pregnant, planning to become pregnant, or nursing, talk to your healthcare provider before taking XIFAXAN.

In the clinical study, the most common side effects associated with XIFAXAN 550 mg tablets—occurring in at least 10% of people receiving XIFAXAN—were peripheral edema (swelling, usually in the ankles or lower limbs), nausea (feeling sick to your stomach), dizziness, fatigue (feeling tired), and ascites (a buildup of fluid in the abdomen).
