What “Xifaxan” generic alternatives are available?
“Xifaxan” is almost certainly a misspelling of Xifaxan/Xifaxan® (rifaximin). A “generic alternative” to Xifaxan typically means an FDA-approved generic version of rifaximin with the same active ingredient (and the same strength and dosing instructions) as the brand product.
How do you find the right rifaximin generic for your indication?
Rifaximin generics can differ by which product they reference (because dosing and prescribing vary by condition). To get the closest alternative, match these details:
- Active ingredient: rifaximin
- Strength (mg)
- Dosage form (typically tablets)
- Indication (for example, traveler’s diarrhea vs. hepatic encephalopathy, depending on the referenced product)
If you share which Xifaxan you’re using (strength and what it’s for), I can narrow down which generic versions are most likely to match.
Are there multiple generics for rifaximin, or just one?
In many cases, multiple manufacturers may market rifaximin generics over time, but which ones are available depends on the specific referenced product (strength/label) and whether exclusivity or patent restrictions delayed additional entrants.

What if you meant a different spelling (Xifaxan vs. Xifaxan)?
If your prescription label uses a slightly different spelling or there’s another similar-sounding drug name, the generic alternative could be different. Common confusion is that “Xifaxan” is often used to refer to rifaximin; if you paste the exact drug name and strength from your prescription, I can confirm the correct generic.
What to ask your pharmacist before switching to a generic
Even when the generic matches the brand active ingredient, patients often want to confirm:
- It’s the same formulation/strength as your current Xifaxan
- Directions match your condition
- Insurance coverage and copay
- Any history of intolerance to rifaximin formulations
If you tell me the strength (e.g., 200 mg or 550 mg) and the condition it’s prescribed for, I can guide you toward the most direct “Xifaxan generic alternative” match.
