A drug that stimulates the production of infection-fighting white blood cells known as granulocytes. G-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. In addition, it may be used to stimulate white blood cell production in patients whose white blood cell levels drop as a side effect of an anti-myeloma treatment.
