About Pegfilgrastim

Pegfilgrastim is a granulocyte colony stimulating factor, also called PEG-GCSF. It helps the body make white blood cells called neutrophils. Neutrophils are white blood cells that fight infections. Some patients need this medicine to help build up neutrophils that have been destroyed by chemotherapy.

This medicine is given once per course of chemotherapy, 24-48 hours after the last dose of chemotherapy.

May be given as a liquid under the skin (subcutaneous)
