Glucotrol XL (glipizide extended release)

Part of the sulfonylurea class of diabetes drugs, Glucotrol XL is the extended-release version of glipizide. It helps beta cells in the pancreas release more insulin. Because type 2 diabetes medications act in different ways to lower blood glucose levels, providers will often prescribe multiple drugs to a patient. Several of the more popular combinations of oral drugs can be prescribed together in a single pill. Each medication has its own side effects. Read labels carefully to be sure you know what they are.
