Different insurance means different laws and different savings. For example, Medicare patients cannot use manufacturer copay cards (federal law) — but the manufacturer almost always has a Patient Assistance Program that gives the drug free.
About VOWST and its cost
What is this medication? VOWST is an oral prescription medication used in adults to prevent the return of Clostridioides difficile infection, which is often referred to as C. diff. It is specifically intended for patients who have already finished a round of antibiotic treatment for a recurring case of the infection. The medication is a fecal microbiota product made from live bacterial spores that are processed from human fecal matter to help re-establish a healthy environment in the intestines. By introducing these beneficial bacteria into the digestive system, the treatment helps to restore the natural balance of the gut flora that may have been destroyed by previous infections or antibiotic therapies. This restoration makes it more difficult for C. diff bacteria to grow and cause future illness. It should be understood that this medication is not meant to treat an active infection but is used as a preventative measure to reduce the risk of the condition coming back again.
VOWST is made by Seres Therapeutics, Inc.. Like most brand-name drugs, it's priced at a high list price — but patients rarely pay that list price. The options above are the real paths most people use to get it affordably.
Common questions
What's the cheapest way to afford VOWST?
It depends on your insurance. On Medicare, apply for the manufacturer's Patient Assistance Program (PAP) — it gives the drug free if you meet income requirements. With private insurance, the manufacturer copay card usually drops your copay to $0-$25. Uninsured patients should compare the PAP with Cost Plus Drugs cash price.
Can I use a copay card with Medicare for VOWST?
No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Seres Therapeutics, Inc. has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.
Does my Medicare Part D plan cover VOWST?
Part D coverage varies by plan. We query the CMS Prescription Drug Plan file to show you what percentage of plans cover it and at what tier. For your exact copay, pick "Medicare" above and check your plan's Summary of Benefits, or log in to Medicare.gov.
How long does a Patient Assistance Program take?
Most PAPs take 2-6 weeks from application to first fill. Ask the manufacturer about a "bridge supply" — many will ship 30 days free while your application is being reviewed so you don't go without the drug.
What if I have a high-deductible plan?
For generics, Cost Plus Drugs cash price is often cheaper than your deductible-phase copay. For brand names, the manufacturer copay card almost always wins. A GoodRx coupon can be a last resort for uncovered drugs, but it doesn't count toward your deductible.
Are there charity grants for C. diff Infection?
Charities like HealthWell Foundation, PAN Foundation, Good Days, and the National Organization for Rare Disorders provide copay help for specific conditions. Funds often run out mid-year — apply early. We list the specific grants for your condition in the options above.
