Glucotrol XL (Glipizide)

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.

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.

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

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.

Store at room temperature between 59-86 degrees F (15-30 degrees C) away from light and moisture. Do not store in the bathroom. Keep all medicines away from children and pets.

• if you will be having surgery

• Beta-blockers (eg, propranolol) because the risk of low blood sugar may be increased. They may also hide certain signs of low blood sugar and make it more difficult to notice
• Angiotensin-converting enzyme (ACE) inhibitors (eg, enalapril), anticoagulants (eg, warfarin), azole antifungals (eg, miconazole, ketoconazole), chloramphenicol, clofibrate, fenfluramine, insulin, monoamine oxidase (MAO) inhibitors (eg, phenelzine), nonsteroidal anti-inflammatory medicines (NSAIDs) (eg, ibuprofen), phenylbutazone, probenecid, quinolone antibiotics (eg, ciprofloxacin), salicylates (eg, aspirin), or sulfonamides (eg, sulfamethoxazole) because the risk of low blood sugar may be increased
• Calcium channel blockers (eg, diltiazem), corticosteroids (eg, prednisone), decongestants (eg, pseudoephedrine), diazoxide, diuretics (eg, furosemide, hydrochlorothiazide), estrogens, hormonal contraceptives (eg, birth control pills), isoniazid, niacin, phenothiazines (eg, promethazine), phenytoin, rifamycins (eg, rifampin), sympathomimetics (eg, albuterol, epinephrine, terbutaline), or thyroid supplements (eg, levothyroxine) because they may decrease Glucotrol XL Extended-Release Tablets's effectiveness, resulting in high blood sugar
• Gemfibrozil because blood sugar may be increased or decreased
