The active substance in Replagal is agalsidase alfa (1mg/ml). Agalsidase alfa is a form of the human enzyme ?-galactosidase. It is produced by switching on the gene for ?-galactosidase A in cells. The enzyme is then removed from the cells and made into a sterile concentrate for solution for infusion.
Replagal is used to treat Fabry Disease. It is used as enzyme replacement therapy when the level of enzyme in the body is lower than normal as in Fabry Disease.

Do not take Replagal
If you are allergic (hypersensitive) to agalsidase alfa or any of the other ingredients of Replagal.
Take special care with Replagal
If you notice any of these effects during or after an infusion you should tell your doctor immediately:
- high fever, chills, sweating, fast heart rate;
- hives, itching or rash;
- swelling in your hands, feet, ankles, face, lips, mouth or throat which may cause difficulty in swallowing or breathing;
- pain or tenderness in chest, muscles or joints.
Your doctor may stop the infusion temporarily (5 ?10 min) until the symptoms go away and then begin the infusion again.
Your doctor may also treat the symptoms with other medicines (antihistamines or corticosteroids). Most of the time you can still be given Replagal even if these symptoms occur.
If you experience a severe allergic (anaphylactic-type) reaction, the administration of Replagal will be immediately discontinued and an appropriate treatment will have to be initiated by your doctor.
If treatment with Replagal makes your body produce antibodies this will not stop Replagal working and the antibodies may disappear with time.
Use in Children
There is limited clinical data in children 7-18 years old. No unexpected safety issues were encountered in the studies with Replagal in children 7-18 years of age. Following treatment with Replagal 0.2mg/kg every other week, changes in the clinical parameters of Fabry disease in children were similar to those seen in earlier adult Fabry patient studies.
Using other medicines
There is no known interaction of Replagal 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.
Taking Replagal with food and drink
Interactions with food or drink are unlikely.
Pregnancy and breast feeding
Very limited clinical data on pregnancies exposed to Replagal (n=4) have shown no adverse effects on the mother and newborn child. Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
You may drive and operate machinery whilst on Replagal.
Replagal has to be diluted in 9 mg/ml (0.9%) sodium chloride solution before use. After dilution Replagal is given in a vein. This will usually be in your arm.
The usual dose is an infusion of 0.2 mg for every kg you weigh. This would be about 14 mg or 4 vials (glass bottles) of Replagal for an average size (70 kg) individual. The infusion will be given every two weeks.
Each time you are treated it will take 40 minutes for Replagal to be given to you in a vein. Your treatment will be supervised by a doctor who specialises in the treatment of Fabry Disease.

Instructions for use, handling and disposal
1. Calculate the dose and number of Replagal vials needed.
2. Dilute the total volume of Replagal concentrate required in 100 ml 9 mg/ml sodium chloride solution for infusion (0.9%w/v). Care must be taken to ensure the sterility of the prepared solutions since Replagal does not contain any preservative or bacteriostatic agent; aseptic technique must be observed. Once diluted, the solution should be mixed gently but not shaken.
3. The solution should be inspected visually for particulate matter and discolouration prior to administration.
4. Administer the infusion solution over a period of 40 minutes using an intravenous line with an integral filter. Since no preservative is present, it is recommended that administration is started as soon as possible and within 3 hours of dilution. However, the chemical and physical stability of the diluted solution has been demonstrated for 24 hours at 25°C.
5. Do not infuse Replagal concomitantly in the same intravenous line with other agents.
6. For single use only. Any unused product or waste material should be disposed of in accordance with local requirements.
