Tell us five things. We’ll do the rest.
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.
Xifaxan offers more than one kind of program, and they have opposite rules:
