1. What Cerezyme is and what it is used for

Cerezyme contains the active substance imiglucerase and 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 bleed 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 β-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 β-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.

2. What you need to know before you are given Cerezyme
Do not use Cerezyme
  • if you are allergic to imiglucerase or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before using 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.

Other medicines and Cerezyme

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).

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Cautious use of Cerezyme during pregnancy and breastfeeding is recommended.

Cerezyme contains sodium

This medicine contains 41 mg sodium (main component of cooking/table salt) per vial. This is equivalent to 2% of the recommended maximum daily dietary intake of sodium for an adult. It is administered in 0.9% sodium chloride intravenous solution. This should be taken into consideration by patients on a controlled sodium diet.

3. How Cerezyme is given

Instructions for proper use

Cerezyme 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.

Cerezyme is only used under the supervision of a doctor who is knowledgeable in the treatment of Gaucher 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.

Your dose will be specific to you. Your doctor will work out your dose based on how severe your symptoms are, and other factors. The recommended dose is 60 units/kg body weight given once every 2 weeks.

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 ICGG Gaucher Registry

You can ask your doctor to register your patient information into the “ICGG Gaucher Registry”. The aims of this Registry are to increase the understanding of Gaucher disease and to check how well enzyme replacement therapy, like Cerezyme, works. This should lead to improvement in the safe and effective use of Cerezyme. Your patient data will be registered anonymously– nobody will know it is information about you.

If you use more Cerezyme than you should

There are no cases of overdose of Cerezyme reported.

If you forget to use Cerezyme

If you have missed an infusion, please contact your doctor.

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