Granulocyte-macrophage colony-stimulating factor (GM-CSF)

A drug that may be used as an alternate to G-CSF (see above). It stimulates the production of infection-fighting white blood cells known as granulocytes and macrophages. Similar to G-CSF, GM-CSF is used to help prevent low white blood cell counts and infection in patients receiving chemotherapy and/or stem cell transplants and is also used to help mobilize stem cells prior to stem cell transplant.
