In malignancies, it is used to increase blood cell counts in patients undergoing chemotherapy and to prevent neutropenia (low levels of neutrophils). Neumax is also used to increase the number of stem cells collected from the patient's bone marrow for autologous transplantation.

Mechanism of Action

Neumax stimulates the production of neutrophils (white blood cells) in the bone marrow.
