1.
WHAT MYOZYME IS AND WHAT IT IS USED FOR
Myozyme is used to treat adults, children and adolescents of all ages
who have a confirmed diagnosis
of Pompe disease.
People with Pompe disease have low levels of an enzyme called
alpha-glucosidase. This enzyme helps
the body control levels of glycogen (a type of carbohydrate). Glycogen
provides the body with energy,
but in Pompe disease the levels of glycogen can get too high.
Myozyme contains an artificial enzyme called alglucosidase alfa –
this can replace the natural enzyme
which is lacking in Pompe disease.
2.
WHAT YOU NEED TO KNOW BEFORE YOU ARE GIVEN MYOZYME
DO NOT USE MYOZYME:
If you have experienced life-threatening allergic (hypersensitive)
reactions to alglucosidase alfa or any
of the other ingredients of this medicine (listed in section 6) and
re-administration of the medicine was
not successful. Symptoms of life-threatening allergic reactions
include, but are not limited to, low
blood pressure, very fast heart rate, difficulty breathing, vomiting,
facial swelling, hives or rash.
WARNINGS AND PRECAUTIONS
If you are treated with Myozyme, you may experience an
infusion-associated reaction while you are
being given the medicine or during the hours following the infusion.
