Glyburide is used with a proper diet and exercise program to control high blood sugar in people with type 2 diabetes. It may also be used with other diabetes medications. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Glyburide belongs to the class of drugs known as sulfonylureas. It lowers blood sugar by causing the release of your body's natural insulin.
Read the Patient Information Leaflet if available from your pharmacist before you start taking glyburide and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Glyburide comes in different types of tablets which provide different amounts of the medication. Do not switch between different forms or brands of this medication unless directed by your doctor.
Take this medication by mouth with breakfast or the first main meal of the day as directed by your doctor, usually once daily. Some patients, especially those taking higher doses, may be directed to take this drug twice a day. The dosage is based on your medical condition and response to treatment.
To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully.
If you are already taking another diabetes drug (such as chlorpropamide), follow your doctor's directions carefully for stopping the old drug and starting glyburide.
If you are also taking colesevelam, take glyburide at least 4 hours before colesevelam.
Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time(s) each day.
Tell your doctor if your condition does not improve or if it worsens (your blood sugar is too high or too low).
Nausea, heartburn, stomach fullness, and weight gain may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including:
This medication can cause low blood sugar (hypoglycemia). This may occur if you do not consume enough calories from food or if you do unusually heavy exercise. Symptoms of low blood sugar include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, or tingling hands/feet. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, rapidly raise your blood sugar by eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor right away about the reaction and the use of this product. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals. Check with your doctor or pharmacist to find out what you should do if you miss a meal.
Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor right away. Your dosage may need to be increased.

Before taking glyburide, tell your doctor or pharmacist if you are allergic to it or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of:
You may experience blurred vision, dizziness, or drowsiness due to extremely low or high blood sugar. Do not drive, use machinery, or do any activity that requires alertness or clear vision until you are sure you can perform such activities safely.
Limit alcohol while taking this medication because it can increase the risk of developing low blood sugar. Rarely, alcohol can interact with glyburide and cause a serious reaction (disulfiram-like reaction) with symptoms such as facial flushing, nausea, vomiting, dizziness, or stomach pain. Consult your doctor or pharmacist about the safe use of alcohol.
It may be harder to control your blood sugar when your body is stressed (such as due to fever, infection, injury, or surgery). Consult your doctor because this may require a change in your treatment plan, medications, or blood sugar testing.
This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.
Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
Older adults may be more sensitive to the side effects of this drug, especially low blood sugar.
During pregnancy, this medication should be used only when clearly needed. Pregnancy may cause or worsen diabetes. Discuss a plan with your doctor for managing your blood sugar while pregnant. Your doctor may substitute insulin for this drug during pregnancy. If glyburide is used, it may be switched to insulin at least 2 weeks before the expected delivery date because of glyburide's risk of causing low blood sugar in your newborn. Discuss the risks and benefits with your doctor.
It is unknown if this medication passes into breast milk. However, similar drugs pass into breast milk. Consult your doctor before breast-feeding.

Many drugs can affect your blood sugar, making it harder to control.

Check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms of high or low blood sugar. (See also Side Effects section.) Your doctor may need to adjust your diabetes medication, exercise program, or diet.
Beta-blocker medications (including metoprolol, propranolol, glaucoma eye drops such as timolol) may prevent the fast/pounding heartbeat you would usually feel when your blood sugar falls too low (hypoglycemia). Other symptoms of low blood sugar such as dizziness, hunger, or sweating are unaffected by these drugs.
Check the labels on all your medicines (such as cough-and-cold products) because they may contain ingredients that could affect your blood sugar. Ask your pharmacist about using those products safely.
