About Exondys 51 and its cost
What is this medication?
Exondys 51, also known by its generic name eteplirsen, is a prescription medication designed to treat Duchenne muscular dystrophy. This is a rare genetic disease that causes muscles to weaken and break down over time. This particular treatment is intended for patients who have a documented mutation of the DMD gene that can be corrected by skipping exon 51 during protein production.
Exondys 51 is made by Sarepta. 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 Exondys 51?
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 Exondys 51?
No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Sarepta has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.
Does my Medicare Part D plan cover Exondys 51?
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 Duchenne Muscular Dystrophy?
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.
