What is Myozyme?

Advertisement

Myozyme (alglucosidase alfa) contains an enzyme that naturally occurs in the body in healthy people. Some people lack this enzyme because of a genetic disorder. Myozyme helps replace this missing enzyme in such people.

Myozyme is used to treat a glycogen storage disorder called Pompe disease, (also called GAA deficiency).

Myozyme may also be used for purposes other than those listed in this medication guide.
