Uses For pegfilgrastim
Pegfilgrastim is a synthetic (man-made) version of a substance that is naturally produced in your body called a colony stimulating factor. It helps the bone marrow to make new white blood cells.
When certain cancer medicines are used to fight cancer cells, they also affect the white blood cells that fight infections. Pegfilgrastim is used to reduce the risk of infection while you are being treated with cancer medicines.
pegfilgrastim is available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, pegfilgrastim is used in certain patients with the following medical conditions:
- Harvesting of peripheral blood stem cells, prior to autologous stem-cell transplantation.
Before Using pegfilgrastim
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For pegfilgrastim, the following should be considered:

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
