pegfilgrastim
(peg-fil-GRAS-tim)
A drug that is a form of filgrastim and is used to prevent infection in adults and children with neutropenia (a lower-than-normal number of white blood cells) caused by some types of chemotherapy. Pegfilgrastim helps the bone marrow make more white blood cells and is able to stay in the body longer than filgrastim, so it doesn't need to be given as often. It is a type of colony-stimulating factor. Also called filgrastim-SD/01, Fulphila, Neulasta, Nyvepria, Udenyca, and Ziextenzo.
