Agalsidase Beta

What Is Agalsidase Beta?

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.
Agalsidase beta is used in the treatment of Fabry disease.
Agalsidase beta may also be used for purposes other than those listed here.
Many people have a severe reaction to agalsidase beta. 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.
To make sure agalsidase beta is safe for you, tell your doctor if you have:
