Filgrastim-sndz

Generic name: Filgrastim-sndz
Drug class: Colony stimulating factors

Usage of Filgrastim-sndz

Filgrastim-sndz 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. Filgrastim-sndz helps the bone marrow 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. Filgrastim-sndz is used to prevent or reduce the risk of infections while you are being treated with cancer medicines. This medicine is also used to help the bone marrow recover after a bone marrow transplantation, for a process called peripheral blood progenitor cell collection in cancer patients.

This medicine is available only with your doctor's prescription.
