1. What Fabrazyme is and what it is used for

Fabrazyme contains the active substance agalsidase beta and is used as enzyme replacement therapy in Fabry disease, where the level of α-galactosidase enzyme activity is absent or lower than normal. If you suffer from Fabry disease a fat substance, called globotriaosylceramide (GL-3), is not removed from the cells of your body and starts to accumulate in the walls of the blood vessels of your organs.

Fabrazyme is indicated for use as long-term enzyme replacement therapy in patients with a confirmed diagnosis of Fabry disease.

Fabrazyme is indicated in adults, children and adolescents aged 8 years and older.

2. What you need to know before you use Fabrazyme
Do not use Fabrazyme
  • if you are allergic to agalsidase beta or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before using Fabrazyme.

If you are treated with Fabrazyme, you may develop infusion associated reactions. An infusion-associated reaction is any side effect occurring during the infusion or until the end of the infusion day (see section 4). If you experience a reaction like this, you should tell your doctor immediately. You may need to be given additional medicines to prevent such reactions from occurring.

Children and adolescents

No clinical studies have been performed in children 0-4 years old. The risks and benefits of Fabrazyme in children aged 5 to 7 years have not yet been established and therefore no dose can be recommended for this age group.

Other medicines and Fabrazyme

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Tell your doctor if you use any medicines containing chloroquine, amiodarone, benoquin or gentamicin. There is a theoretical risk of decreased agalsidase beta activity.

Pregnancy, breast-feeding and fertility

There is limited experience with the use of Fabrazyme in pregnant women. As a precaution, it is preferable to avoid the use of Fabrazyme during pregnancy. Fabrazyme gets into breast milk. Discuss with your doctor the risks and benefits of breastfeeding versus continuing Fabrazyme therapy. Studies have not been performed to examine the effects of Fabrazyme on fertility.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Driving and using machines

Do not drive or use machines if you experience dizziness, sleepiness, vertigo or fainting during or shortly after administration of Fabrazyme (see section 4). Talk to your doctor first.

Fabrazyme contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per vial, that is to say essentially ‘sodium-free’.

3. How to use Fabrazyme

Fabrazyme is given through a drip into a vein (by intravenous infusion). It is supplied as a powder which will be mixed with sterile water before it is given (see information for Health Care Professionals at the end of this leaflet).

Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.

Fabrazyme is only used under the supervision of a doctor who is knowledgeable in the treatment of Fabry disease. Your doctor may advise that you can be treated at home provided you meet certain criteria. Please contact your doctor if you would like to be treated at home.

The recommended dose of Fabrazyme for adults is 1 mg/kg body weight, once every 2 weeks. No changes in dose are necessary for patients with kidney disease.

Use in children and adolescents

The recommended dose of Fabrazyme for children and adolescents 8 – 16 years is 1 mg/kg body weight, once every 2 weeks. No changes in dose are necessary for patients with kidney disease.

If you use more Fabrazyme than you should

Doses up to 3 mg/kg body weight have shown to be safe.

If you forget to use Fabrazyme

If you have missed an infusion of Fabrazyme, please contact your doctor.

If you have any further questions on the use of this medicine, ask your doctor.
