Uses for pegfilgrastim-apgf

Pegfilgrastim-apgf injection is used to treat neutropenia (low white blood cells) that is caused by cancer medicines. It is a synthetic (man-made) form of a substance that is naturally produced in your body called a colony stimulating factor. Pegfilgrastim-apgf helps the bone marrow to make new white blood cells.

When certain cancer medicines are used to fight cancer cells, they also affect the white blood cells that fight infections. Pegfilgrastim-apgf is used to reduce the risk of infection while you are being treated with cancer medicines.

Pegfilgrastim-apgf is available only with your doctor's prescription.
