XIFAXAN significantly reduced the risk of overt HE recurrence and HE-related hospitalizations1*

Study design1,2
- In a randomized, placebo-controlled, double-blind, multicenter, multinational, 6-month study, the efficacy of XIFAXAN 550 mg (taken orally twice a day) was evaluated in 299 adult subjects
- Inclusion criteria: Currently in remission (Conn score of 0 or 1) from HE and ≥2 episodes of HE associated with chronic liver disease in the previous 6 months
- Primary endpoint: Time to first breakthrough overt HE episode, defined as a marked deterioration in neurological function (an increase in Conn score to grade ≥2 or an increase in Conn score and asterixis grade of 1 each if subject entered study at grade 0)
- Key secondary endpoint: HE-related hospitalization
XIFAXAN has a low number needed to treat (NNT)2
- NNT of 14 to prevent one diabetes-related death in 10 years with metformin3,4
- NNT of 12-26 to prevent one cardiovascular event in 10 years with statins5
The above data are not a comparison of NNT among different treatments but are intended to provide an overview of published data on NNT.
HE = hepatic encephalopathy

XIFAXAN® (rifaximin) 550 mg tablets are indicated for the reduction in risk of overt hepatic encephalopathy (HE) recurrence in adults and for the treatment of irritable bowel syndrome with diarrhea (IBS-D) in adults.
IMPORTANT SAFETY INFORMATION
- XIFAXAN is contraindicated in patients with a hypersensitivity to rifaximin, rifamycin antimicrobial agents, or any of the components in XIFAXAN. Hypersensitivity reactions have included exfoliative dermatitis, angioneurotic edema, and anaphylaxis.
- Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including XIFAXAN, and may range in severity from mild diarrhea to fatal colitis. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued.
