Elaprase is used to improve the walking ability in those with Hunter Syndrome. Your doctor may give you a medication before receiving Elaprase to help prevent certain serious allergic reactions.
Elaprase is a prescription medication used to improve walking ability in patients with Hunter syndrome who are 5 years and older.
Elaprase belongs to a group of drugs called enzymes. It works by replacing iduronate-2-sulfatase (I2S), an enzyme that people with Hunter syndrome do not have enough of.
This medication comes in injectable form to be given directly into a vein (IV) by a healthcare professional. It is given once a week as an infusion.
Common side effects of Elaprase include diarrhea, muscle pain, itching, and headache.

Risk of Antibody Development.

Your doctor will monitor you for development of these antibodies.

Elaprase and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
Elaprase falls into category C. There are no well-controlled studies that have been done in pregnant women. Elaprase should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.
Elaprase and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed.
It is not known if Elaprase crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, your doctor will determine if you should continue to take Elaprase or stop breastfeeding. Your doctor and you will decide if the benefits outweigh the risk of using Elaprase.
This medication is available in an injectable form to be given directly into a vein (IV) by a healthcare professional. It is given once a week as an infusion.
Typically, the infusion can take up to 3 hours, but may be longer if you have had an allergic reaction to Elaprase. The infusion should not be given over longer than 8 hours.
If you miss an appointment to receive a dose of Elaprase, contact your healthcare provider to make plans to receive your next infusion.
The dose your doctor recommends will be based on your weight.
The recommended dose of Elaprase is 0.5 mg per kg body weight given once a week as an intravenous (IV) infusion.
Since Elaprase is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.

Patients with compromised respiratory function or acute respiratory disease may be at risk of serious acute exacerbation of their respiratory compromise due to hypersensitivity reactions, and require additional monitoring.
