Alglucosidase alfa is used to treat a rare genetic disorder called Pompe disease in which the person’s body is unable to store glycogen properly. Glycogen is needed to convert carbohydrates into glucose so that the body’s cells can get the energy they need to perform vital functions. Alglucosidase alfa replaces a missing enzyme in the body so that people with Pompe disease can metabolize glucose correctly.
