Uses

Filgrastim is a man-made version of a certain natural substance made by your body. It is used to help your body make more white blood cells. White blood cells are important to help you fight off infections. Filgrastim is given to people whose ability to make white blood cells is reduced (for instance, due to chemotherapy, chronic neutropenia, or exposure to large amounts of radiation). It is also used in certain treatment procedures (such as bone marrow/stem cell transplant).

This monograph is about the following filgrastim products: filgrastim, tbo-filgrastim, filgrastim-sndz, filgrastim-aafi, and filgrastim-ayow.
