This medication is used to treat anemia (low red blood cell count) in people with long-term serious kidney disease (chronic kidney disease). It works by signaling the bone marrow to make more red blood cells. Methoxy polyethylene glycol-epoetin beta helps to reverse anemia. It also helps to reduce the need for blood transfusions. This medication is very similar to the natural substance in your body (erythropoietin) that prevents anemia.

Methoxy polyethylene glycol-epoetin beta may sometimes cause or worsen high blood pressure, especially in patients with long-term kidney failure. This effect may be caused by the number of red blood cells increasing too quickly, usually within the first 3 months of starting treatment. If you have high blood pressure, it should be well controlled before beginning treatment with this medication. Your blood pressure should be checked often. Ask your doctor if you should learn how to check your own blood pressure. If high blood pressure develops or worsens, follow your doctor's instructions about diet changes and starting or adjusting your high blood pressure medication. Lowering high blood pressure helps prevent strokes, heart attacks, and further kidney problems. Keep all lab appointments to have your red blood cell count/hemoglobin level tested regularly to reduce the chance of this side effect.
