Glucotrol XL

Drug Name

Glucotrol XL (Glipizide)

Drug Uses

Glucotrol XL is used for treating type 2 diabetes in patients who cannot control blood sugar levels by diet and exercise alone. It is used along with diet and exercise. It may be used alone or with other antidiabetic medicines.

How Taken

Use Glucotrol XL as directed by your doctor. Check the label on the medicine for exact dosing instructions.
Take Glucotrol XL by mouth with breakfast or the first main meal of the day unless your doctor tells you otherwise. Swallow Glucotrol XL whole. Do not break, crush, or chew before swallowing.
Glucotrol XL works best if it is taken at the same time each day.
Continue to take Glucotrol XL even if you feel well. Do not miss any doses.

Drug Class and Mechanism

Glucotrol XL is a sulfonylurea antidiabetic medicine. It causes the pancreas to release insulin, which helps to lower blood sugar.

Missed Dose

If you miss a dose of Zyvox, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
