Pegfilgrastim is a medicine used to reduce the risk of infection in people with certain types of cancer or blood disorders. It is a form of granulocyte-colony stimulating factor (G-CSF) that works by stimulating the production of neutrophils, a type of white blood cell that fights infection. Pegfilgrastim is commonly used to prevent neutropenia (low white blood cell count) in people undergoing chemotherapy or radiation therapy for cancer. It is given as an injection under the skin or into a vein.
Pegfilgrastim is a medication that helps the body produce more white blood cells, specifically neutrophils. Neutrophils are a type of white blood cell that helps the body fight infection. Pegfilgrastim is used to reduce the risk of infection in people who have certain types of cancer and are receiving chemotherapy medications that may decrease the number of neutrophils. It is also used to increase the chance of survival in people who have been exposed to harmful amounts of radiation.
Pegfilgrastim is a man-made form of a protein called granulocyte colony-stimulating factor (G-CSF). G-CSF is a natural substance that helps the body produce white blood cells. Pegfilgrastim is different from G-CSF because it has a molecule attached to it that helps it stay in the body longer. This allows pegfilgrastim to work for a longer period of time than G-CSF.
Pegfilgrastim is given as an injection under the skin (subcutaneously). It is usually given once a day for several days. The exact dosage and schedule of pegfilgrastim will vary depending on the individual's condition and treatment plan.
Pegfilgrastim can cause some side effects. The most common side effects include bone pain, muscle aches, fatigue, nausea, vomiting, headache, and rash. Pegfilgrastim can also cause serious side effects, including an increased risk of spleen rupture and leukemia. It is important to talk to your doctor about the risks and benefits of pegfilgrastim before taking this medication.
