About Halaven and its cost

What is this medication? Halaven is a prescription chemotherapy medication used to treat specific types of advanced cancer. Its generic name is eribulin mesylate, and it works by interfering with the growth of cancer cells, specifically by inhibiting the formation of microtubules within the cells. This process prevents the cancer cells from dividing and eventually leads to their death. It is primarily prescribed for adults who have been diagnosed with metastatic breast cancer after they have already received at least two other types of chemotherapy treatments, such as an anthracycline and a taxane.

In addition to its use for breast cancer, Halaven is also indicated for the treatment of people with a specific type of soft tissue cancer called liposarcoma that cannot be removed by surgery or has spread throughout the body. This is specifically for patients who have previously undergone treatment with a different class of chemotherapy known as anthracyclines. The medication is typically administered by a healthcare professional through an intravenous injection in a clinical setting. It is not a cure for cancer but is intended to help manage the disease and potentially extend survival in advanced stages.

Halaven 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 Halaven?

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 Halaven?

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 Halaven?

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.
