Xifaxan (rifaximin) is a non-systemic antibiotic (rifamycin) made by Salix Pharmaceuticals (Bausch Health). It is commonly prescribed for: Irritable bowel syndrome with diarrhea (IBS-D), Hepatic encephalopathy (HE) recurrence reduction, Travelers' diarrhea (TD). Without financial assistance, Xifaxan typically costs around $2,000 per month.
Income limits
1 of the 2 active Xifaxan assistance programs we track caps household income. The lowest cutoff is $47,880 a year for a single person. Most programs publish their cutoff as a percent of the federal poverty level - here is what that means in dollars.
Household income at or below 300% of the federal poverty level:
| Household size | Annual income limit |
|---|---|
| 1 person | $47,880 |
| 2 people | $64,920 |
| 3 people | $81,960 |
| 4 people | $99,000 |
| Each additional person | + $17,040 |
Dollar amounts for percent-of-poverty caps are computed from the 2026 federal poverty guidelines for the 48 contiguous states and Washington, DC ($15,960 for one person, plus $5,680 for each additional household member). Alaska and Hawaii use higher figures. Each program makes the final eligibility decision - confirm on the official application linked above.

Medicare coverage for Xifaxan depends on your own plan: depending on how it is given, a drug can fall under Part B (administered in a clinic) or Part D (filled at a pharmacy), and each plan decides what it covers. Your plan's documents or Medicare's plan finder are the only reliable check. Separate from coverage, none of the Xifaxan assistance programs we track currently accept Medicare patients.
