What should I know about tolazamide before taking it?

Tolazamide combined with diet and exercise, and sometimes with other medications, is used to treat type 2 diabetes. Tolazamide, a sulfonylurea, lowers blood sugar by causing the pancreas to secrete more insulin (a hormone that is needed to break down sugar in the body) and helping the body use insulin efficiently. This medication will only help lower blood sugar in people whose bodies produce insulin naturally. Tolazamide is not used to treat type 1 diabetes (condition in which the body does not produce insulin and, therefore, cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may occur if high blood sugar is not treated).
