About Cerezyme

Overview

Cerezyme (imiglucerase) is an enzyme replacement medicine given into a vein. It treats manifestations of Type 1 or Type 3 Gaucher disease outside the brain and spinal cord in adults and children. It replaces deficient enzyme activity to help break down glucocerebroside, a substance that builds up in tissues such as the liver, spleen and bone marrow.

What it treats

Type 1 or Type 3 Gaucher disease in adults and children, for manifestations that do not involve the central nervous system.

Safety information

FDA boxed warning

Hypersensitivity reactions including anaphylaxis

Patients treated with enzyme replacement therapies have experienced life-threatening hypersensitivity reactions, including anaphylaxis. Anaphylaxis has occurred during the early course of enzyme replacement therapy and after extended duration of therapy.

Initiate CEREZYME in a healthcare setting with appropriate medical monitoring and support measures, including access to cardiopulmonary resuscitation equipment. If a severe hypersensitivity reaction (e.g., anaphylaxis) occurs, discontinue CEREZYME and immediately initiate appropriate medical treatment, including use of epinephrine. Inform patients of the symptoms of life-threatening hypersensitivity reactions, including anaphylaxis and to seek immediate medical care should symptoms occur.

A boxed warning is the strongest warning the US Food and Drug Administration requires on a medicine label. Text is taken from the official label, with internal section references removed.

When to call your doctor

- Seek immediate medical attention for a severe allergic reaction (anaphylaxis). This can happen early in treatment or after long-term treatment. - Alert your healthcare team immediately if you experience a severe reaction during an infusion.

If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.

Before taking this medicine

The label lists no contraindications for Cerezyme. Infusion-associated reactions may occur. If a severe reaction occurs, Cerezyme must be stopped immediately and appropriate medical treatment started.
