What is Fabrazyme?
Fabrazyme (agalsidase beta) is a man-made form of the naturally-occurring alpha-galactosidase A enzyme. A deficiency of this enzyme is called Fabry disease. Agalsidase beta reduces deposits of globotriaosylceramide (GL-3) in the kidneys and certain other cells in the body.
Fabrazyme is used in the treatment of Fabry disease.
Fabrazyme may also be used for purposes other than those listed here.
Many people have a severe reaction to Fabrazyme. Tell your caregiver right away if you have a side effect such as: skin rash or hives, fever, chills, headache, muscle pain, dizziness, numbness, swelling, vomiting, diarrhea, chest pain, trouble swallowing or breathing, fast or slow heart rate, or feeling light-headed.
Most patients treated with Fabrazyme develop antibodies to agalsidase beta and many will develop symptoms of an infusion reaction. A slow rate of injection of the medication and pretreatment with other medications may decrease the severity of these symptoms. Emergency medical attention may be required if a severe allergic reaction is experienced.
Before using Fabrazyme
To make sure Fabrazyme is safe for you, tell your doctor if you have:
