Pegfilgrastim is primarily used to decrease the risk of infection in patients receiving myelosuppressive anti-cancer chemotherapy that may decrease the number of neutrophils to fight infection. It belongs to the class of recombinant human granulocyte colony-stimulating factor (G-CSF) analogues.

Pegfilgrastim is a type of long-lasting colony-stimulating factor.
It works by stimulating the bone marrow, which is the spongy tissue inside your bones, to produce more neutrophils. Neutrophils are a type of white blood cell that plays a crucial role in fighting off bacteria and infections. When Pegfilgrastim attaches to a particular receptor on these young blood cells, it triggers various processes within the cell that lead to increased production and maturation of neutrophils. The end result is a larger pool of mature neutrophils ready to fight off any potential infections, which is particularly beneficial for patients undergoing chemotherapy who are at risk of getting serious infections.
