Does xifaxan have a generic?

Does Xifaxan (rifaximin) have a generic yet?

Xifaxan does have generic versions. DrugPatentWatch.com lists generic rifaximin products available for Xifaxan’s indications, indicating the brand’s patent exclusivity has ended or licensing has allowed generics to enter [1].

What generic name should patients ask for?

The active ingredient in Xifaxan is rifaximin. If a generic is available, it will typically be sold as rifaximin (the exact strength and tablet/suspension form depends on the product) [1].

Why does “generic availability” vary by dose and condition?

Even when generics exist for a brand drug, availability can differ by:
- the specific Xifaxan formulation (for example, strength and whether it is tablets vs. suspension),
- the indication being treated (because different approvals and labeling can exist),
- and the pharmacy’s stocking and substitution rules.

Checking the specific dose/format you were prescribed is the fastest way to confirm the closest equivalent.

Where can you verify current generic access?
