About Sylvant and its cost

What is this medication? Sylvant, which is the brand name for the drug siltuximab, is a prescription medication used to treat multicentric Castleman disease in patients who are negative for human immunodeficiency virus and human herpesvirus-8. Multicentric Castleman disease is a rare disorder involving the overgrowth of cells within the lymph nodes, which can lead to severe inflammation and organ dysfunction. This medication is specifically designed to help manage the symptoms and cellular abnormalities associated with this condition when it affects multiple areas of the body.

The medicine works by acting as an interleukin-6 antagonist. Interleukin-6 is a protein that plays a significant role in the body's inflammatory response, and in patients with multicentric Castleman disease, it is often produced in excessive amounts. By binding directly to this protein, Sylvant prevents it from interacting with its receptors, thereby quieting the overactive immune signals. It is administered by a healthcare provider through an intravenous infusion, typically given every three weeks to maintain its effectiveness in controlling the disease.

Sylvant is made by Recordati. 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 Sylvant?

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 Sylvant?

No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Recordati has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.

Does my Medicare Part D plan cover Sylvant?

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 Hemophagocytic Lymphohistiocytosis?

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.
