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 OXLUMO and its cost
What is this medication? OXLUMO is a prescription medication used for the treatment of primary hyperoxaluria type 1, which is a rare genetic disorder that affects both children and adults. In individuals with this condition, the liver produces far too much oxalate, a waste product that the kidneys are responsible for filtering. High oxalate levels can lead to the formation of painful kidney stones and the accumulation of crystals in the kidneys, which may eventually cause organ failure or systemic oxalosis.
This medication belongs to a class of drugs called RNA interference therapeutics and works by lowering the amount of oxalate the liver produces. It specifically targets an enzyme called glycolate oxidase to block the metabolic pathway that creates excess oxalate. By reducing the overall oxalate burden in the body, the drug helps to preserve kidney function and prevent the disease from worsening over time. It is administered via an injection under the skin by a healthcare provider.
OXLUMO is made by Alnylam. 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 OXLUMO?
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 OXLUMO?
No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Alnylam has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.
Does my Medicare Part D plan cover OXLUMO?
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 Lesch-Nyhan Syndrome?
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.
