Patient Education

Methoxy Polyethylene Glycol-Epoetin Beta Injection


Methoxy polyethylene glycol-epoetin beta 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) in adults on and not on dialysis and in children 5 years of age and older on dialysis who have already received another treatment for anemia. Methoxy polyethylene glycol-epoetin beta injection should not be used to treat anemia caused by cancer chemotherapy and should not be used in place of a red blood cell transfusion to treat severe anemia. Methoxy polyethylene glycol-epoetin beta injection 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.
