1. What is Fabrazyme and what is it used for
Fabrazyme contains the active substance agalsidase beta and is used as enzyme replacement therapy in Fabry disease, in which the level of enzyme activity of alpha-Galactosidase is non-existent or below normal. In people with Fabry disease, a fatty substance called globotriaosylceramide (GL-3) is not removed from the body's cells and accumulates in the walls of blood vessels of organs.
Fabrazyme is indicated for long-term enzyme replacement therapy in patients with a confirmed diagnosis of Fabry disease.
Fabrazyme is indicated for use in adults, adolescents, and children 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 you start using Fabrazyme.
If you are being treated with Fabrazyme, you may develop infusion-related reactions. An infusion-related reaction is any adverse event that occurs during the infusion or up to the end of the infusion day (see section 4). If you experience such a reaction, you should tell your doctor immediately. You may need other medicines to prevent such reactions.
Children and adolescents
No clinical studies have been conducted in children from 0 to 4 years. The risks and benefits of Fabrazyme in children between 5 and 7 years of age 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 are using other medicines that contain chloroquine, amiodarone, benoquin, or gentamicin. There is a theoretical risk of reduced agalsidase beta activity.
Pregnancy, breastfeeding, and fertility
Experience with the use of Fabrazyme in pregnant women is limited. As a precaution, it is recommended to avoid the use of Fabrazyme during pregnancy. Fabrazyme passes into breast milk. Talk to your doctor about the risks and benefits of breastfeeding versus continuing treatment with Fabrazyme. No studies have been conducted to examine the effects of Fabrazyme on fertility.
If you are pregnant or breastfeeding, or think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
Driving and using machines
Do not drive or use tools or machines if you experience dizziness, drowsiness, vertigo, or fainting during or soon after the administration of Fabrazyme (see section 4). Talk to your doctor first.
Fabrazyme contains sodium
This medicine contains less than 1mmol of sodium (23 mg) per vial; this is essentially “sodium-free”.
3. How to use Fabrazyme
Fabrazyme is administered by infusion into a vein (intravenous infusion). It is supplied as a powder that will be mixed with sterile water before administration (see information for healthcare professionals at the end of this leaflet).
Follow exactly the administration instructions of this medicine given by your doctor. If you are in doubt, ask your doctor again.
Fabrazyme is only used under the supervision of a doctor with experience in the treatment of Fabry disease. If you meet certain criteria, your doctor may consider that you can receive treatment at home. Contact your doctor if you wish to receive treatment at home.
The recommended dose of Fabrazyme for adults is 1 mg/kg body weight, every 2 weeks. No dose adjustment is needed in patients with renal disease.
Use in children and adolescents
The recommended dose of Fabrazyme for children and adolescents from 8 to 16 years is 1 mg/kg body weight, every 2 weeks. No dose adjustment is needed in patients with renal disease.
If you use more Fabrazyme than you should
Doses of up to 3 mg/kg body weight have been shown to be safe.
If you forget to use Fabrazyme
If you have missed an infusion of Fabrazyme, contact your doctor.
If you have any other questions on the use of this medicine, ask your doctor.
4. Possible side effects
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 receiving the medicine or soon after (“infusion-related reactions”). Potentially life-threatening severe allergic reactions (“anaphylactic reactions”) have been reported in some patients. If you experience any serious side effect, contact your doctor immediately.
Some very common side effects (may affect more than 1 in 10 people) include chills, fever, feeling of cold, nausea, vomiting, headache, and abnormal skin sensations such as burning or tingling. Your doctor may decide to reduce the infusion rate or administer additional medicines to prevent such reactions.

Instructions for use – reconstitution, dilution, and administration
The powder for concentrate for solution for infusion must be reconstituted with water for injections, diluted with sodium chloride 0.9% injection solution, and then administered by intravenous infusion.
From a microbiological point of view, the product should be used immediately. If not used immediately, storage and handling are the responsibility of the user. The reconstituted solution cannot be stored and must be diluted promptly; only the diluted solution can be kept for up to 24 hours at 2°C to 8°C.
Use aseptic technique
- The number of vials needed for reconstitution should be calculated based on the patient's weight, and the required vials should be removed from the refrigerator to reach room temperature (approximately 30 minutes). Each vial of Fabrazyme is for single use.
Reconstitution
- Each vial of Fabrazyme 35 mg should be reconstituted with 7.2 ml of water for injections. Avoid vigorous impact of the water for injections on the powder and foam formation. This is achieved by slowly adding the water for injections through the inner wall of the vial and not directly onto the lyophilized cake. Each vial should be tilted and gently rotated. The vial should not be inverted, turned, or shaken.
- The reconstituted solution contains 5 mg of agalsidase beta per ml and appears clear and colorless. The pH of the reconstituted solution is approximately 7.0. Before further dilution, the reconstituted solution of each vial should be visually inspected for particulate matter or color change. The solution should not be used if particles or color changes are observed.
- After reconstitution, it is recommended to dilute the vials promptly to minimize protein particle formation over time.
- Disposal of unused medicinal products and all materials that have come into contact with them should be done in accordance with local regulations.
Dilution
- Before adding the required volume of reconstituted Fabrazyme for the patient's dose, it is recommended to remove an equivalent volume of sodium chloride 0.9% injection solution from the infusion bag.
- The air in the infusion bag should be eliminated to minimize the air/liquid interface.
- Slowly withdraw 7.0 ml (equivalent to 35 mg) from the reconstituted solution of each vial to complete the required volume for the patient's dose. Do not use filter needles, and avoid foam formation.
- Slowly inject the reconstituted solution directly into the sodium chloride 0.9% injection solution (avoiding injection into an air space) to a final concentration between 0.05 mg/ml and 0.7 mg/ml. The total volume of sodium chloride 0.9% injection solution (between 50 and 500 ml) should be determined based on the individual dose. For doses below 35 mg, a minimum of 50 ml should be used; for doses of 35 to 70 mg, a minimum of 100 ml should be used; for doses of 70 to 100 mg, a minimum of 250 ml should be used; and for doses above 100 mg, only 500 ml should be used. The infusion bag should be gently inverted or massaged to mix the diluted solution. The infusion bag should not be shaken or agitated excessively.
Administration
- For administration of the diluted solution, it is recommended to use an in-line filter with a pore size of 0.2 μm and low protein-binding to remove any protein particles, which will not result in any loss of agalsidase beta activity. The initial infusion rate (IV) should not exceed 0.25 mg/min (15 mg/hour). The infusion rate can be reduced in case of infusion-associated reactions (IARs).
Once the patient's tolerance has been well established, the infusion rate can be increased in increments of 0.05 to 0.083 mg/min (increments of 3 to 5 mg/hour) with each subsequent infusion. In clinical trials with classical patients, the infusion rate was progressively increased to reach a minimum of 2 hours. This was achieved after 8 initial infusions at 0.25 mg/min (15 mg/hour) without any IARs, changes in infusion rate, or interruption of infusion. A further reduction in infusion time to 1.5 hours was allowed for patients without new IARs during the last 10 infusions or without serious adverse events reported in the last 5 infusions. Each increase in infusion rate of 0.083 mg/min (~5 mg/hour) was maintained for 3 consecutive infusions without new IARs, changes in infusion rate, or interruption of infusion before subsequent rate increases.
For patients weighing <30 kg, the maximum infusion rate should remain at 0.25 mg min (15 hour).< p>
