Ask for the cash price

Releuko

Releuko is a biologic. Biologics don’t have generics, but some have biosimilars or an unbranded version from the same maker. Ask your pharmacist or prescriber whether one is sold.

  1. Ask your pharmacy for Releuko’s cash price, and one or two other pharmacies too.
  2. Releuko’s savings card works only with insurance from a job or one you bought.

Free from the maker, if you qualify Amneal Biosciences Patient Assistance Program. Or call 1-877-764-9021.

Maker’s card or discount card?

A discount card like GoodRx lowers the pharmacy’s cash price, but for a brand-name drug that price often stays high. Compare it with the maker’s card above. You can usually use one or the other on a fill, not both.

Authorized genericNot sold

There isn’t one. An authorized generic is Releuko itself, from the same company, sold without the brand name, and usually for less. For now Releuko is the only choice; its maker’s savings card can lower what you pay.

Regular genericNot sold

Releuko is a biologic. Biologics don’t have generics, but some have biosimilars or an unbranded version from the same maker. Ask your pharmacist or prescriber whether one is sold. Generics usually come once the brand’s patents and exclusivity end. Until then, the maker’s savings card is the way to pay less.

What it’s used for

What the FDA label says

RELEUKO is a leukocyte growth factor indicated to:

  • Decrease the incidence of infection‚ as manifested by febrile neutropenia‚ in patients with nonmyeloid malignancies receiving myelosuppressive anti- cancer drugs associated with a significant incidence of severe neutropenia with fever.
  • Reduce the time to neutrophil recovery and the duration of fever, following induction or consolidation chemotherapy treatment of patients with acute myeloid leukemia (AML).
  • Reduce the duration of neutropenia and neutropenia-related clinical sequelae‚ e.g.‚ febrile neutropenia, in patients with nonmyeloid malignancies undergoing myeloablative chemotherapy followed by bone marrow transplantation (BMT).
  • Mobilize autologous hematopoietic progenitor cells into the peripheral blood for collection by leukapheresis
  • Reduce the incidence and duration of sequelae of severe neutropenia (e.g., fever‚ infections‚ oropharyngeal ulcers) in symptomatic patients with congenital neutropenia‚ cyclic neutropenia‚ or idiopathic neutropenia.
  • Increase survival in patients acutely exposed to myelosuppressive doses of radiation (Hematopoietic Syndrome of Acute Radiation Syndrome)
