Xifaxan can cost over $2,000/month. Learn how to save with coupons, discount cards, the manufacturer savings card, and patient assistance programs.
Xifaxan (Rifaximin) is an effective medication for hepatic encephalopathy and irritable bowel syndrome with diarrhea — but its price tag can be shocking. Without insurance, a one-month supply can cost over $2,000. Even with insurance, copays can be significant.
The good news? There are several legitimate ways to reduce your out-of-pocket costs. In this guide, we'll break down every savings option available for Xifaxan in 2026.
Let's start with the numbers. Here's what Xifaxan typically costs at retail pharmacies without insurance coverage:
Prices vary by pharmacy and location. The 550 mg strength used for HE and IBS-D is significantly more expensive than the 200 mg travelers' diarrhea formulation.
There is no generic version of Xifaxan available as of 2026. Rifaximin's patent exclusivity extends through 2028-2029, which means there's no lower-cost generic alternative at the pharmacy counter.
The best deal for commercially insured patients is the manufacturer's own savings card.
If you have commercial insurance, this card should be your first step. It can reduce your copay from hundreds of dollars to zero.
If you don't have insurance, or if your insurance doesn't cover Xifaxan, prescription discount cards can help — though the savings are more modest with a drug this expensive.
These cards are free to use and accepted at most major pharmacies. While the discount on Xifaxan may not be as dramatic as it is for generic medications, every dollar counts when you're paying this much out of pocket.
Tip: Prices vary significantly between pharmacies. Check multiple locations and discount cards before filling your prescription. Independent pharmacies sometimes offer better cash prices than large chains.
If you're uninsured, underinsured, or facing financial hardship, patient assistance programs can provide Xifaxan for free or at a significantly reduced cost.
The manufacturer of Xifaxan offers a patient assistance program for qualifying patients:
The PAN Foundation provides copay assistance to patients with specific diagnoses who meet financial criteria:
If you're on long-term Xifaxan therapy (especially for hepatic encephalopathy), ask your insurance company about mail-order pharmacy. Benefits include:
If your insurance denies coverage or places Xifaxan on a high copay tier, you have the right to appeal. Your doctor can write a letter of medical necessity explaining why Xifaxan is essential for your condition. This can sometimes result in:
Xifaxan prices can vary by hundreds of dollars between pharmacies. Use Medfinder not only to find pharmacies with stock but also to compare pricing in your area.
Your doctor may have Xifaxan samples from the manufacturer that can tide you over while you work through insurance approvals or assistance program applications. It doesn't hurt to ask.
You're likely on long-term therapy (550 mg twice daily, ongoing). Your monthly costs without savings could exceed $2,000. Priority savings strategies:
Your course is shorter (550 mg three times daily for 14 days), but you may need repeat courses. Total cost per course: $1,400-$1,800. Use the same savings strategies, and ask your doctor whether a repeat course is necessary before filling.
Xifaxan is expensive, but there are real ways to reduce your costs — sometimes to $0. Start with the manufacturer savings card if you have commercial insurance. If you're on Medicare or uninsured, explore patient assistance programs. And always compare prices across pharmacies.
