Patient Education

Darbepoetin Alfa Injection


Darbepoetin alfa injection is used to treat anemia (a lower than normal number of red blood cells) in people with chronic kidney failure (condition in which the kidneys slowly and permanently stop working over a period of time). Darbepoetin alfa injection is also used to treat anemia caused by chemotherapy in people with certain types of cancer. Darbepoetin alfa cannot be used in place of a red blood cell transfusion to treat severe anemia and has not been shown to improve tiredness or poor well-being that may be caused by anemia. Darbepoetin alfa is in a class of medications called erythropoiesis-stimulating agents (ESAs). It works by causing the bone marrow (soft tissue inside the bones where blood is made) to make more red blood cells.
