What is filgrastim (Neupogen)?
Filgrastim is a man-made form of a protein that stimulates the growth of white blood cells in your body. White blood cells help your body fight against infection.
Filgrastim is used to treat neutropenia, a lack of certain white blood cells caused by cancer, bone marrow transplant, receiving chemotherapy, or by other conditions.
Filgrastim may also be used for purposes not listed in this medication guide.
