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.

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.

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

Like all medicines, this medicine can cause side effects, although not everybody gets them.

In clinical studies side effects were mainly seen while patients were being given the medicine or shortly after (“infusion related reactions”). Severe life-threatening allergic reactions (“anaphylactoid reactions”) have been reported in some patients. If you experience any serious side effect, you should contact your doctor immediately.

Very common symptoms (may affect more than 1 in 10 people) include chills, fever, feeling cold, nausea, vomiting, headache and abnormal feelings in the skin such as burning or tingling. Your doctor may decide to lower the infusion rate or give you additional medicines to prevent such reactions from occurring.
