Generic Name: glipizide (GLIP-i-zide)
Brand Name: Glucotrol
Glipizide 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.

- you have certain severe problems associated with diabetes (eg, diabetic ketoacidosis, diabetic coma)
- you have very high blood acid levels (acidosis)
- you have type 1 diabetes
- you are pregnant and are within 1 month of the expected delivery date
Contact your doctor or health care provider right away if any of these apply to you.

Some MEDICINES MAY INTERACT with glipizide. Tell your health care provider if you are taking any other medicines, especially any of the following:
- 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 inhibitors (MAOIs) (eg, phenelzine), nonsteroidal anti-inflammatory drugs (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 glipizide's effectiveness, resulting in high blood sugar
- Gemfibrozil because blood sugar may be increased or decreased
This may not be a complete list of all interactions that may occur. Ask your health care provider if glipizide may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use glipizide:
Use glipizide as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take glipizide by mouth 30 minutes before a meal as directed by your doctor.
- If you are taking 1 dose daily, take glipizide 30 minutes before breakfast or the first main meal of the day unless your doctor tells you otherwise.
- If you also take colesevelam, take glipizide at least 4 hours before your dose of colesevelam. Check with your doctor if you have questions.
- Glipizide works best if it is taken at the same time each day.
- Continue to take glipizide even if you feel well. Do not miss any doses.
- If you miss a dose of glipizide, 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.
Ask your health care provider any questions you may have about how to use glipizide.
Important safety information:
- Glipizide may cause drowsiness, dizziness, blurred vision, or light-headedness. These effects may be worse if you take it with alcohol or certain medicines. Use glipizide with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Check with your doctor before you drink alcohol while you are taking glipizide. Alcohol may increase the risk of low blood sugar. Rarely, alcohol may interact with glipizide and cause a serious reaction with symptoms such as flushing, nausea, vomiting, dizziness, or stomach pain. Discuss any questions or concerns with your doctor.
- Carry an ID card at all times that says you have diabetes. Check your blood sugar levels as directed by your doctor. If they are often higher or lower than they should be and you take glipizide exactly as prescribed, tell your doctor.
- Proper diet, regular exercise, and regular blood sugar testing are important for best results with glipizide. Follow the diet and exercise program given to you by your health care provider.
- It may be harder to control your blood sugar during times of stress, such as fever, infection, injury, or surgery. Talk with your doctor about how to control your blood sugar if any of these occur. Do not change the dose of your medicine without checking with your doctor.
- Glipizide may cause low blood sugar levels. Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your heart beat faster; make your vision change; give you a headache, chills, or tremors; or make you hungrier. It is a good idea to carry a reliable source of glucose (eg, tablets or gel) to treat low blood sugar. If this is not available, you should eat or drink a quick source of sugar like table sugar, honey, candy, orange juice, or non-diet soda. This will raise your blood sugar level quickly. Tell your doctor right away if this happens. To prevent low blood sugar, eat meals at the same time each day and do not skip meals.
- Risk of low blood sugar may be increased by severe or prolonged exercise, drinking alcohol, or skipping meals.
- Glipizide is a sulfonylurea. It may increase the risk of death from heart disease. Talk with your doctor about the benefits and risks of this or other therapies to treat your condition.
- Glipizide may cause you to become sunburned more easily. Avoid the sun, sunlamps, or tanning booths until you know how you react to glipizide. Use a sunscreen or wear protective clothing if you must be outside for more than a short time.
- Glipizide should not be used by itself to treat type 1 diabetes. If you have questions about using glipizide to treat type 1 diabetes, talk with your doctor.
- Tell your doctor or dentist that you take glipizide before you receive any medical or dental care, emergency care, or surgery.
- Lab tests, including fasting blood glucose, hemoglobin A1c, and liver function, may be performed while you take glipizide. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Use glipizide with caution in the ELDERLY; they may be more sensitive to its effects, especially low blood sugar levels. Low blood sugar levels may also be more difficult to recognize in the elderly.
- Glipizide should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.
- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of taking glipizide while you are pregnant. Glipizide should not be taken if you are within 1 month of the expected delivery date because it may cause low blood sugar in the baby. It is not known if this medicine is found in breast milk. Do not breast-feed while taking glipizide.
When used for long periods of time, glipizide may not work as well. If your blood sugar has been under control and then becomes hard to manage, contact your doctor. Do not change the dose of your medicine without checking with your doctor.
