What is it and how is it used?

Elaprase is used as enzyme replacement therapy to treat Hunter syndrome (Mucopolysaccharidosis II) when the level of the enzyme iduronate-2-sulfatase in the body is lower than normal. If you suffer from Hunter syndrome, a carbohydrate called glycosaminoglycan which is normally broken down by your body is not broken down and slowly accumulates in various organs in your body causing these cells to function abnormally, thereby causing problems for various organs in your body which can lead to tissue destruction and organ failure. Elaprase works by acting as a replacement for the enzyme that is at a low level, thereby breaking down this carbohydrate in affected cells.

Enzyme replacement therapy is usually administered as a long-term treatment.


What do you have to consider before using it?

Do not use Elaprase
If you are allergic (hypersensitive) to idursulfase or any of the other ingredients of Elaprase.

Take special care with Elaprase
If you are treated with Elaprase you may experience reactions during or following an infusion (see section 4 Possible Side Effects). The most common symptoms are itching, rash, hives, fever, headache, increased blood pressure, and flushing (redness). Most of the time you can still be given Elaprase even if these symptoms occur. If you experience an allergic side effect following administration of Elaprase, you should contact your doctor immediately. You may be given additional medicines such as antihistamines and corticosteroids to treat or help prevent allergic-type reactions.

If severe allergic (anaphylactic-type) reactions occur, your doctor will stop the infusion immediately, and start giving you suitable treatment. You may need to stay in hospital.

Using other medicines
There is no known interaction of Elaprase with other medicines.

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Using Elaprase with food and drink
Due to the way the product is broken down by the body interactions with food and drink are unlikely.

Pregnancy and breast-feeding
Use of Elaprase during pregnancy is not recommended. Elaprase may get into breast milk therefore you should talk to your doctor or pharmacist before using this medicine if you are breast-feeding.

Driving and using machines
It is not known if Elaprase will affect the ability to drive or use machines.

How is it used?

Elaprase should only be used under the supervision of a doctor or healthcare professional (e.g. nurse) who is knowledgeable in the treatment of Hunter syndrome or other inherited metabolic disorders. Elaprase has to be diluted in 9 mg/ml (0.9%) sodium chloride solution for infusion before use. The usual dose is an infusion of 0.5 mg (half a milligram) for every kg you weigh. After dilution Elaprase is given through a vein (drip feed). The infusion will normally last for 1 to 3 hours and will be given every week.

If you use more Elaprase than you should
There is no experience with overdoses of Elaprase.

If you forget to have Elaprase
