This medication lowers blood sugar by stimulating the pancreas to secrete insulin and helping the body use insulin efficiently. The pancreas must produce insulin for this drug to work. Tolbutamide is not used to treat type I (insulin-dependent) diabetes (formerly 'juvenile-onset').

Tolbutamide is in a class of drugs called sulfonylureas. It is used together with diet and exercise to help control blood sugar levels and treat type II diabetes mellitus.

Insulin or metformin (Glucophage®) may also be used in combination with tolbutamide, if necessary.
