What is rifaximin 550 mg, and what is the generic used for?
Rifaximin 550 mg is a prescription-strength dose of rifaximin, an antibiotic that stays mostly in the gut. It is commonly used for gastrointestinal conditions where bacterial overgrowth or intestinal infections are involved, depending on the exact FDA-labeled indication and local prescribing guidelines.

Is “rifaximin 550 mg” the same as Xifaxan 550 mg?
Yes. “Generic rifaximin 550 mg” typically means a generic version of the branded 550 mg rifaximin tablet product (commonly referenced as Xifaxan 550 mg), using the same active ingredient and strength. The exact inactive ingredients and tablet formulation can differ by manufacturer, but the active drug strength is the same.
How do you switch between generic rifaximin manufacturers safely?
If you change from one generic rifaximin manufacturer to another, it should still be therapeutically equivalent if it is an approved generic. Patients and clinicians generally focus on:
- matching the same dose (550 mg)
- staying on the same prescribed dosing schedule
- checking with the pharmacist if the pill size/color changes
- reporting any unexpected loss of response or side effects
If you tell me your country (or whether you mean the U.S.), I can narrow this to the specific approved products you’re likely to see.

What do patients usually ask about rifaximin 550 mg generics?

If you share the reason you’re taking it (what condition your prescription is for), I can tailor what to expect from rifaximin 550 mg and what questions to ask your pharmacist.
