Consumer Medicine Information
 

NOTICE: This Consumer Medicine Information (CMI) is intended for persons living in Australia. This page contains answers to some common questions about Elaprase. It does not contain all the information that is known about Elaprase. It does not take the place of talking to your doctor or pharmacist. All medicines have risks and benefits. Your doctor has weighed the risk of you using this medicine against the benefits he/she expects it will have for you. If you have any concerns about using this medicine, ask your doctor or pharmacist. Bookmark or print this page, you may need to read it again.

What Elaprase is used for

Elaprase is used as enzyme replacement therapy to treat Hunter syndrome, a rare genetic disease in which an enzyme called iduronate-2-sulfatase is missing or the level of the enzyme is lower than normal.
Hunter syndrome generally occurs in males and rarely in females.
Elaprase is available only with a doctor's prescription. Only your or your child's treating doctor can start the treatment and supervise the ongoing treatment.
Elaprase is to be given only to the person for whom it has been prescribed.

How it works

Patients with Hunter syndrome do not produce enough of their own enzyme, iduronate-2-sulfatase. The reduced iduronate-2-sulfatase levels in patients result in the accumulation of substances called glycosaminoglycans (GAG), in a number of cell types and tissues. This causes the affected cells and tissues to function abnormally, thereby causing problems for various organs in the body.
Elaprase is an enzyme replacement therapy that is intended to restore sufficient levels of enzyme to assist in the removal of the accumulated substances and to reduce further accumulation.
Ask your treating doctor if you have any questions about why it has been prescribed for you or your child.
