Neupogen

Generic name: Filgrastim
Drug class: Colony stimulating factors

Usage of Neupogen

Neupogen (filgrastim) is used to decrease the chance of infection in people who have non myeloid cancer (cancer that does not involve the bone marrow) and are receiving chemotherapy medications that may decrease the number of Neutrophils (a type of blood cell needed to fight infection).

Neupogen is also used to help increase the number of white blood cells, and decrease the length of time with fever in people with acute myeloid leukemia (AML; a type of cancer of the white blood cells) who are receiving treatment with chemotherapy medications.

Neupogen is also used in people who are undergoing bone marrow transplants and in people who have severe chronic neutropenia (condition in which there are a low number of neutrophils in the blood).

Neupogen is used to prepare the blood for leukapheresis (a treatment in which certain blood cells are removed from the body.

Neupogen is also used to increase the chance of survival in people who have been exposed to harmful amounts of radiation, which can cause severe and life-threatening damage to your bone marrow.

Neupogen belongs to a class of medications called colony-stimulating factors. It works by helping the body make more neutrophils.
