About Eribulin Mesylate and its cost

What is this medication? Eribulin mesylate is a chemotherapy drug categorized as a microtubule inhibitor, designed to treat specific forms of advanced cancer. It functions by interfering with the internal structures of cancer cells, preventing them from dividing and effectively slowing the spread of the disease. This medication is primarily indicated for patients with metastatic breast cancer who have previously undergone at least two other chemotherapy regimens. By targeting the cell division process, it aims to manage the progression of the illness when other treatments have already been utilized.

This medication is also used to treat patients with liposarcoma, a rare type of cancer that originates in fatty tissue, when the condition is metastatic or cannot be surgically removed. It is generally prescribed for those who have already received previous treatment with an anthracycline-based chemotherapy. Administered as an intravenous injection by medical professionals, eribulin mesylate is typically given in cycles to allow the body time to recover between doses. Patients undergoing this therapy require regular clinical monitoring to ensure the medication is being managed safely and effectively.

Eribulin Mesylate is made by Eisai. 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 Eribulin Mesylate?

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 Eribulin Mesylate?

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

Does my Medicare Part D plan cover Eribulin Mesylate?

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 Cancer?

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.
