Epoetin injection is a man-made version of human erythropoietin (EPO). EPO is produced naturally in the body, mostly by the kidneys. It stimulates the bone marrow to produce red blood cells. If the body does not produce enough EPO, severe anemia can occur.
Erythropoietin can be used to correct anemia by stimulating red blood cell production in the bone marrow in these conditions. The medication is known as epoetin alfa (Epogen, Procrit) or as darbepoietin alfa (Arnesp). It can be given as an injection intravenously (into a vein) or subcutaneously (under the skin).
