Cerezyme – Imiglucerase uses, dose and side effects


400 units powder for concentrate for infusion solution 

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 Gaucher disease type 1 or type 3, and who show the following signs of the disease: anemia ( anemia ), a tendency to bleed easily (due to low numbers) platelets – a type of blood cell), enlargement of the spleen or liver, or skeletal disease.

People with Gaucher disease have low levels of an enzyme called acidic β-glucosidase. This enzyme helps the body control the levels of glucosylceramide. Glucosylceramide is a natural substance in the body and consists of sugar and fat. In Gaucher’s disease, glucosylceramide levels may be too high.

Cerezyme is an artificial enzyme called imiglucerase. It can replace the natural enzyme an acidic β-glucosidase that is missing or not sufficiently active in patients with Gaucher disease.

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

Warnings and cautions

Talk to your doctor or pharmacist before using Cerezyme:

  • if you are being treated with Cerezyme you may have an allergic reaction while receiving the medicine or shortly afterward. If you get such a reaction, you must 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 may be unknown, or it may be due to heart, lung or liver problems. It may occur whether the patient is being treated with Cerezyme or not. However, if you suffer from shortness of breath, you must tell your doctor.

Other medicines and Cerezyme

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Cerezyme must not be given mixed with other medicines in the same infusion (drip).

Pregnancy and breastfeeding

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. Careful use of Cerezyme during pregnancy and lactation is recommended.

Cerezyme contains sodium

The drug contains sodium and is administered in 0.9% sodium chloride intravenous solutions. This should be considered by patients on a low-salt diet. This medicine contains 280 mg of sodium (the main ingredient in common salt/table salt) per vial. This corresponds to 14% of the maximum recommended daily intake of sodium for adults.

3. How Cerezyme is given

Instructions for proper use
Cerezyme is given via a drip into a vein (by intravenous infusion ).

It is delivered as a powder which must be mixed with sterile water before it is given.

Cerezyme should only be used under the supervision of a doctor who is knowledgeable in the treatment of Gaucher’s disease . Your doctor may recommend that you receive treatment at home, provided you meet certain criteria. Contact your doctor if you want to receive treatment at home.

Your dose is specific to you. Your doctor will calculate dose one based on how severe your symptoms are and other factors. The recommended dose is 60 units/kg body weight once every two weeks.

The doctor carefully monitors how you react to the treatment, and can change someone (increase or decrease) until he / she finds the best dose to control your symptoms.

Once the doctor has found the right dose, he/she will still check your reactions to make sure you are using the right dose. This can be done every 6 to 12 months.

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

ICGG Gaucher Registry
You can ask your doctor to register your patient information in the “ICGG Gaucher Registry”. The purpose of this registry is to increase understanding of Gaucher’s disease and to check how well enzyme replacement therapy, such as Cerezyme, works. This should lead to an improvement in the safety and efficacy of Cerezyme. Your patient data is registered anonymously – no one gets to know that the information is about you.

If you use more Cerezyme than you should

No cases of overdose of Cerezyme have been reported.

If you forget to use Cerezyme
