Glyburide is used along with diet and exercise, and sometimes with other medications, to treat type 2 diabetes (condition in which the body does not use insulin normally and, therefore, cannot control the amount of sugar in the blood). Glyburide is in a class of medications called sulfonylureas. Glyburide lowers blood sugar by causing the pancreas to produce insulin (a natural substance that is needed to break down sugar in the body) and helping the body use insulin efficiently. This medication will only help lower blood sugar in people whose bodies produce insulin naturally. Glyburide is not used to treat type 1 diabetes (condition in which the body does not produce insulin and, therefore, cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may occur if high blood sugar is not treated).
Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Taking medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.
Glyburide comes as a tablet to take by mouth. It is usually taken once a day with breakfast or the first main meal of the day. However, in some cases your doctor may tell you to take glyburide twice a day. To help you remember to take glyburide, take it at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take glyburide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of glyburide and gradually increase your dose if needed. After you have taken glyburide for some time, glyburide may not control your blood sugar as well as it did at the beginning of your treatment. Your doctor may adjust the dose of your medication as needed so that the medication will work best for you. Be sure to tell your doctor how you are feeling and if your blood sugar test results have been higher or lower than normal at any time during your treatment.
Glyburide helps control blood sugar but does not cure diabetes. Continue to take glyburide even if you feel well. Do not stop taking glyburide without talking to your doctor.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Before taking glyburide,
Be sure to follow all exercise and dietary recommendations made by your doctor or dietitian. It is important to eat a healthy diet, exercise regularly, and lose weight if necessary.
Before you start to take glyburide, ask you doctor what you should do if you forget to take a dose. Write these directions down so that you can refer to them later.
As a general rule, take the missed dose as soon as you remember it. If it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site

Keep all appointments with your doctor and the laboratory. Your fasting blood sugar levels and glycosylated hemoglobin (HbA1c) should be checked regularly to determine your response to glyburide. Your doctor may order other lab tests to check your response to glyburide. Your doctor will also tell you how to check your response to this medication by measuring your blood sugar levels at home. Follow these instructions carefully.
You should always wear a diabetic identification bracelet to be sure you get proper treatment in an emergency.
