The program provides free medication for up to one year to eligible patients who meet income and other requirements.[1][2][3] ## About Xifaxan and Why Assistance Matters **Xifaxan** (rifaximin) is a gut-specific antibiotic that targets harmful bacteria in the intestines without being absorbed into the bloodstream. It's commonly prescribed for: - **Irritable Bowel Syndrome with Diarrhea (IBS-D)**: Reduces recurrent abdominal pain and loose stools. - **Traveler's Diarrhea**: Caused by noninvasive strains of *E. coli*. - **Hepatic Encephalopathy**: Helps prevent episodes in adults with liver disease.[1][3] Without insurance, Xifaxan can cost over $2,000 per treatment course, making it unaffordable for many. The Bausch Health PAP bridges this gap by offering the medication at **no cost** to qualified patients, ensuring continued treatment for better health outcomes.[2][3] ## Who Qualifies for the Program?
