Discontinuation of Coverage: Xifaxan (Rifaximin)*
Effective October 1, 2025, the manufacturer of Xifaxan (Rifaximin) will no longer participate in the Medicaid Drug Rebate Program which means it will not be covered by MaineCare. Please read below for alternative options.
Patient Assistance Program for Free Medication
Bausch Health Companies, Inc. offers a patient assistance program aimed at supplying free medication, including Xifaxan, to eligible patients who do not have coverage under their Medicaid pharmacy benefit.
Prescribers with patients taking Xifaxan (Rifaximin) can complete an application to request access through the patient assistance program on the Bausch Health Companies, Inc website. Please work with your patient to complete the application because it asks for clinical information.
Alternative Medications
If the patient assistance program is not an option, please review covered medications and available alternatives in the MaineCare Preferred Drug List.
