Why is this medication prescribed?
Chlorpropamide is used to treat type II (noninsulin-dependent) diabetes (formerly 'adult-onset'), particularly in people whose diabetes cannot be controlled by diet alone. Chlorpropamide lowers blood sugar by stimulating the pancreas to secrete insulin and helping the body to use insulin efficiently. The pancreas must produce insulin for this medication to work. Chlorpropamide is not used to treat type I (insulin-dependent) diabetes (formerly 'juvenile-onset').
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
