ZAVESCA® (miglustat) can make a difference when used alone to treat adults with mild-to-moderate type 1 Gaucher disease.1

ZAVESCA is used to help treat mild to moderate type 1 Gaucher disease in adults. It is prescribed only for people who cannot be treated with enzyme replacement therapy. Keep in mind that it may take time for ZAVESCA to work in ways you can notice. Even though some people taking ZAVESCA may not feel better right away, they can experience benefits that their doctors can measure. Individual results may vary.

Talk to your doctor if you have questions.
