Palifermin

WHY is this medicine prescribed?

Palifermin is used to prevent and to speed the healing of severe sores in the mouth and throat that may be caused by chemotherapy and radiation therapy used to treat cancers of the blood or bone marrow (soft fatty material in the middle of bones that makes blood cells). Palifermin may not be safe to use to prevent and treat mouth sores in patients who have other types of cancer. Palifermin is in a class of medications called human keratinocyte growth factors. It works by stimulating the growth of cells in the mouth and throat.

HOW should this medicine be used?

Palifermin comes as a powder to be mixed with liquid to be injected intravenously (into a vein). It is usually given once a day for 3 days in a row before you receive your chemotherapy treatment and then once a day for 3 days in a row after you receive your chemotherapy for a total of 6 doses. You will not be given palifermin on the same day that you are given your cancer chemotherapy treatment. Palifermin must be given at least 24 hours before and at least 24 hours after you receive your chemotherapy treatment.
