Your doctor prescribed ZIEXTENZO to help reduce the risk of infection during chemotherapy. ZIEXTENZO is a man-made form of granulocyte colony-stimulating factor (G-CSF) called pegfilgrastim. G-CSF is a natural substance produced by the body. The purpose of G-CSF is to stimulate the growth of neutrophils, a type of white blood cell important in the body's fight against infection.
