Why was ZIEXTENZO prescribed for me?

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.

A biosimilar is a treatment option that is highly similar to a name-brand biologic (known as a reference product). Biosimilars must go through rigorous testing to be approved by the FDA.
Biosimilars and their reference products have no clinically meaningful differences in function, efficacy, and safety.
Based on a simulation model, patients prescribed Zarxio® (filgrastim-sndz)—the Sandoz short-acting filgrastim biosimilar—could save an average of ≈10% in out-of-pocket spending per year
