About Dificid, DIFICID and its cost
What is this medication? Dificid, also known by the generic name fidaxomicin, is a prescription antibiotic medication primarily used to treat infections caused by the bacterium Clostridioides difficile. This condition, often referred to as C. diff, is a serious intestinal infection that can cause severe diarrhea and inflammation of the colon. Unlike many other antibiotics that are absorbed into the bloodstream to treat systemic issues, Dificid stays mostly within the gastrointestinal tract to target the bacteria directly where they are causing the problem.
This medication belongs to a class of drugs called macrolide antibiotics and works by inhibiting the production of essential proteins in the bacteria, eventually leading to their death. It is typically prescribed to adults and children who have been diagnosed with C. diff-associated diarrhea. Patients are advised to take the full course of the medication as prescribed by their healthcare provider, even if symptoms improve quickly, to ensure the infection is completely cleared and to help prevent it from returning or becoming resistant to treatment.
Dificid, DIFICID is made by Merck. 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 Dificid, DIFICID?
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 Dificid, DIFICID?
No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Merck has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.
Does my Medicare Part D plan cover Dificid, DIFICID?
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 your condition?
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.
