Patient’s Leaflet

What is it and how is it used?

Cerezyme is used to treat patients who have a confirmed diagnosis of Type I or Type 3 Gaucher disease, who show signs of the disease such as: anaemia (low number of red blood cells), a tendency to bleeding easily (due to low numbers of platelets ? a type of blood cell), spleen or liver enlargement or bone disease.

People with Gaucher disease have low levels of an enzyme called acid -glucosidase. This enzyme helps the body control levels of glucosylceramide. Glucosylceramide is a natural substance in the body, made of sugar and fat . In Gaucher disease glucosylceramide levels can get too high.

Cerezyme is an artificial enzyme called imiglucerase -this can replace the natural enzyme acid -glucosidase which is lacking or not active enough in patients with Gaucher disease.

The information in this leaflet applies to all patient groups including children, adolescents, adults and the elderly.

What do you have to consider before using it?

Do not use Cerezyme
  • If you are allergic (hypersensitive) to imiglucerase, or
  • if you are allergic to any of the other ingredients of Cerezyme.
Take special care with Cerezyme
  • If you are treated with Cerezyme, you may experience an allergic reaction while you are being given the medicine or shortly after. If you experience a reaction like this, you should tell your doctor immediately. Your doctor may test if you have an allergic reaction to imiglucerase.
  • Some patients with Gaucher disease have high blood pressure in the lungs (pulmonary hypertension). The cause can be unknown, or it can be due to heart, lung or liver problems. It can occur whether the patient is treated with Cerezyme or not. But, if you suffer with any shortness of breath you should tell your doctor.

Using 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.

Cerezyme should not be given as a mixture with other medicinal products in the same infusion (drip).

Your doctor will keep a close check on your response to your treatment, and may change your dose (up or down) until he/she finds the best dose to control your symptoms.

Once this dose is found your doctor will still keep a check on your responses to make sure you are using the right dose. This might be every 6 to 12 months.

There is no information on the effect of Cerezyme on brain-based symptoms of patients with chronic neuronopathic Gaucher disease. Therefore no special dosage regimen can be recommended.

The following information is intended for medical or healthcare professionals only:

Instructions for use ? reconstitution, dilution and administration
Each vial of Cerezyme is for single use only. After reconstitution, each vial of Cerezyme contains 400 units of imiglucerase in 10.0 ml (40 units per ml).

Determine the number of vials to be reconstituted based on the individual patient's dosage regimen and remove the vials from the refrigerator.

Use Aseptic TechniqueReconstitution
Reconstitute each vial with 10.2 ml water for injections; avoid forceful impact of water for injections on the powder and, by mixing gently, avoid foaming of the solution. The reconstituted volume is 10.6 ml. The pH of the reconstituted solution is approximately 6.1.

After reconstitution it is a clear, colourless liquid, free from foreign matter. The reconstituted solution must be further diluted. Before further dilution, visually inspect the reconstituted solution in each vial for foreign particles and discoloration. Do not use vials exhibiting foreign particles or discoloration. After reconstitution, promptly dilute vials and do not store for subsequent use.


The reconstituted solution contains 40 units imiglucerase per ml. The reconstituted volume allows accurate withdrawal of 10.0 ml (equal to 400 units) from each vial. Withdraw 10.0 ml reconstituted solution from each vial and combine the withdrawn volumes. Then dilute the combined volumes with 0.9% sodium chloride intravenous solution to a total volume of 100 to 200 ml. Mix the infusion solution gently.


It is recommended to administer the diluted solution through an in-line low protein-binding 0.2 µm filter to remove any protein particles. This will not lead to any loss of imiglucerase activity. It is recommended that the diluted solution be administered within 3 hours. The product diluted in 0.9% sodium chloride intravenous solution will retain chemical stability if stored up to 24 hours at 2°C and 8°C under protection from light; but microbiological safety will depend on the reconstitution and dilution having been performed aseptically.

Cerezyme contains no preservatives. Any unused product or waste material should be disposed of in accordance with local requirements.
