Is there a generic version of Xifaxan (rifaximin) available in Canada?
Xifaxan is the brand name for rifaximin. Whether a lower-cost “generic Xifaxan” is available in Canada depends on which rifaximin product you mean (for example, prescription rifaximin tablets) and what authorization exists in Canada for the same active ingredient, strength, and dosage form.
Why you might not see a “Xifaxan generic” listing (even if generic rifaximin exists)
In Canada, you may see:
- Generic rifaximin sold under a non-brand name (often “rifaximin” plus strength), not as “Xifaxan generic.”
- Limited listings for specific strengths/dosage forms, even if generic versions exist for others.
- Supply and substitution rules that can affect what pharmacies have on hand.
How to check the right Canadian product (strength, dosage form, and NDC-style equivalents)
To find the closest match in Canada, you typically need to confirm:
- Active ingredient: rifaximin
- Strength (for example, 200 mg or 550 mg, depending on the regimen)
- Dosage form (tablet)
- Indication/regimen (for example, hepatic encephalopathy vs. traveler’s diarrhea uses different dosing)
If you tell me the exact Xifaxan strength and what it’s prescribed for, I can help narrow what the generic would likely be called in Canada.

What to do at the pharmacy if you want the cheapest equivalent
When asking for a Canadian “Xifaxan generic,” pharmacies usually need:
- Your prescription with the drug name and strength (or a substitution-allowed note from your prescriber)
- Confirmation that the generic is the same dosage form and strength
If you want, share the exact wording from your prescription (or the strength) and your province, and I’ll translate that into what to ask the pharmacist for in Canada (generic name + strength match).
