Uses For Zavesca
Miglustat is used to treat mild to moderate type 1 Gaucher disease in people who cannot be treated with an enzyme replacement therapy. Type 1 Gaucher disease is a disease you get from both your parents. People with type 1 Gaucher disease lack an enzyme (naturally occurring substance in your body) that breaks down a chemical in your body called glucosylceramide. Too much glucosylceramide causes liver and spleen enlargement, changes in the blood, and bone disease. Miglustat works by stopping the body from making glucosylceramide.
This medicine is available only with your doctor's prescription.
