Avandia is an oral diabetes medicine that helps control blood sugar levels by making the cells of the body more sensitive to the action of insulin.

Avandia is for people with type 2 (non-insulin-dependent) diabetes. Avandia is sometimes used in combination with insulin or other medications, but it is not for treating type 1 diabetes.

Avandia may also be used for other purposes not listed in this medication guide.
