US Brand Name
Tbo-filgrastim injection is used to treat severe 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 the body called a colony stimulating factor. Tbo-filgrastim 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. Tbo-filgrastim is used to prevent or reduce the risk of infection while you are being treated with cancer medicines.
