About ZARXIO and its cost

What is this medication? Zarxio is a prescription medication that belongs to a class of drugs known as leukocyte growth factors. It is a biosimilar to another drug called Neupogen and contains the active ingredient filgrastim. The primary function of this medication is to stimulate the bone marrow to produce more white blood cells, specifically a type called neutrophils. These cells are vital for the immune system to protect the body against bacterial infections.

This medication is most commonly used by patients with cancer who are undergoing chemotherapy treatments that may lower their white blood cell count. By increasing these cell levels, Zarxio helps decrease the risk of infection and prevents the development of fever associated with low white blood cell counts. It is also prescribed for patients receiving bone marrow transplants, those preparing for blood progenitor cell collection, and individuals with certain types of severe chronic neutropenia. The medication is typically administered via an injection under the skin or through an intravenous infusion.

ZARXIO is made by Sandoz. 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 ZARXIO?

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 ZARXIO?

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

Does my Medicare Part D plan cover ZARXIO?

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 Congenital Neutropenia?

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.
