What is Releuko?

Releuko is used to treat neutropenia (lack of certain white blood cells) in patients receiving certain cancer medications, undergoing a bone marrow transplant, or caused by other conditions.

Neupogen, Zarxio, and Nivestym can be used in a procedure called leukapheresis, where white blood cells needed for a stem cell transplant are removed from the body.

Neupogen is also used in patients who have been exposed to a certain amount of radiation.

Releuko may also be used for purposes not listed in this medication guide.
