Miglustat

Generic Name: miglustat (MI-GLOO-stat)

Treating mild to moderate type I Gaucher disease in patients for whom enzyme replacement therapy is not appropriate.

Miglustat is a glucosylceramide synthase inhibitor. It works by reducing the formation of certain substances in the body (glucosylceramide-based glycosphingolipids). This helps to relieve some of the blood, liver, spleen, and other organ problems caused by type I Gaucher disease.

Do NOT use miglustat if:

  • you are allergic to any ingredient in miglustat
  • you have severe kidney problems

Contact your doctor or health care provider right away if any of these apply to you.
