Fabrazyme is used as enzyme replacement therapy in Fabry disease, where the level of ?-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.

Do not use Fabrazyme
If you have experienced an allergic anaphylactic reaction to agalsidase beta or if you are allergic (hypersensitive) to any of the other ingredients of Fabrazyme.
Take special care with 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 4 ?Possible Side Effects?). 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.
Different groups of patients using Fabrazyme
The information in this leaflet applies to all patient groups including children, adolescents, adults and the elderly.
Using other medicines
There are no known interactions with other medicinal products. Fabrazyme should not be administered with chloroquine, amiodarone, benoquin or gentamicin due to a theoretical risk of decreased agalsidase beta activity. Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Using Fabrazyme with food and drink
Interactions with food and drink are unlikely.
Pregnancy and breast-feeding
Use of Fabrazyme during pregnancy is not recommended. There is no experience with the use of Fabrazyme in pregnant women. Fabrazyme may get into breast milk. Use of Fabrazyme during breast-feeding is not recommended. Ask your doctor or pharmacist for advice before taking this medicine.
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)
Fabrazyme is only used under the supervision of a doctor who is knowledgeable in the treatment of Fabry disease.
The recommended dose of Fabrazyme for adults and children 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
There are no cases of overdose of Fabrazyme reported. 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.

Instructions for use ? reconstitution, dilution and administration
The powder for concentrate for solution for infusion has to be reconstituted with water for injections, diluted with 0.9% sodium chloride intravenous solution and then administered by intravenous infusion.
From a microbiological point of view, the product should be used immediately. If not used immediately, in-use storage and conditions are the responsibility of the user. The reconstituted solution cannot be stored and should be promptly diluted; only the diluted solution can be held for up to 24 hours at 2ºC -8º C.
Use Aseptic Technique
1. Determine the number of vials to be reconstituted based on the individual patient's weight and remove the required vials from the refrigerator in order to allow them to reach room temperature (in approximately 30 minutes). Each vial of Fabrazyme is intended for single use only.
2. Reconstitute each vial of Fabrazyme 35 mg with 7.2 ml water for injections. Avoid forceful impact of the water for injections on the powder and avoid foaming. This is done by slow drop-wise addition of the water for injection down the inside of the vial and not directly onto the lyophilized cake. Roll and tilt each vial gently. Do not invert, swirl or shake the vial.
3. The reconstituted solution contains 5 mg agalsidase beta per ml, and appears as a clear colourless solution. The pH of the reconstituted solution is approximately 7.0. Before further dilution, visually inspect the reconstituted solution in each vial for particulate matter and discoloration. Do not use the solution if foreign particles are observed or if the solution is discoloured.
4. After reconstitution it is recommended to promptly dilute the vials, to minimize protein particle formation over time.
5. Any unused product or waste material should be disposed of in accordance with local requirements.
6. Prior to adding the reconstituted volume of Fabrazyme required for the patient dose, it is recommended to remove an equal volume of 0.9% sodium chloride intravenous solution, from the infusion bag.
7. Remove the airspace within the infusion bag to minimize the air/liquid interface.
8. Slowly, withdraw 7.0 ml (equal to 35 mg) of the reconstituted solution from each vial up to the total volume required for the patient dose. Do not use filter needles and avoid foaming.
9. Then slowly inject the reconstituted solution directly into the 0.9% sodium chloride intravenoussolution (not in any remaining airspace) to a final concentration between 0.05 mg/ml and 0.7 mg/ml. Determine the total volume of sodium chloride 0.9% solution for infusion (between 50 and 500 ml) based on the individual dose. For doses lower than 35 mg use a minimum of 50 ml, for doses 35 to 70 mg use a minimum of 100 ml, for doses 70 to 100 mg use a minimum of 250 ml and for doses greater than 100 mg use only 500 ml. Gently invert or lightly massage the infusion bag to mix the diluted solution. Do not shake or excessively agitate the infusion bag.
10. It is recommended to administer the diluted solution through an in-line low protein-binding 0.2 µm filter to remove any protein particles which will not lead to any loss of agalsidase beta activity. The initial infusion rate should be no more than 0.25 mg/min (15 mg/hour) to minimise the potential occurrence of infusion-associated reactions. After patient tolerance is established, the infusion rate may be increased gradually with subsequent infusions.
