1 What is Mircera?

Brand: Mircera

Generic: Methoxy Polyethylene Glycol-Epoetin Beta

Mircera is used in the treatment of anemia (low red blood cells) in a patient with chronic kidney disease.

Methoxy polyethylene glycol-epoetin beta is a synthetic form of erythropoietin (a protein normally made by the kidneys) which stimulates bone marrow to produce red blood cells.

In chronic kidney diseases or failure, the kidney is unable to make enough erythropoietin and so results in severe anemia. It is available in the form of solution only with your doctor’s prescription.
