What is XIFAXAN (zī-fax-an)?

XIFAXAN is a nonsystemic* antibiotic that slows the growth of bacteria in the gut that are believed to be linked to symptoms of overt hepatic encephalopathy (HE). It has been proven to reduce the risk of overt HE recurrence and HE-related hospitalizations in adults.

*There is an increased systemic exposure in patients with severe (Child-Pugh Class C) hepatic impairment. Caution should be exercised when administering XIFAXAN to these patients.

XIFAXAN reduced two risks associated with overt HE

In a clinical study, adults with a history of overt HE took one XIFAXAN 550 mg tablet 2 times a day for 6 months. 91% of patients took lactulose at the same time. The results were:
