What is glyburide used for?
Glyburide is an oral diabetes medicine that helps control blood sugar levels.
Glyburide is used to treat type 2 diabetes. This medicine is not for treating type 1 diabetes.
Glyburide may also be used for purposes not listed in this medication guide.
How should I take glyburide?
Take glyburide exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Take glyburide with your first meal of the day, unless your doctor tells you otherwise.
Your blood sugar will need to be checked often, and you may need other blood tests at your doctor’s office.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, confusion, irritability, dizziness, or feeling shaky. Always keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency.
If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it.
Older adults may be more likely to have low blood sugar while taking glyburide.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, and weight loss.
Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. Do not change your medication dose or schedule without your doctor’s advice.
Also check your blood sugar levels very closely during pregnancy.
If your doctor changes your brand, strength, or type of glyburide, your dosage needs may change. Ask your pharmacist if you have any questions about the new kind of glyburide you receive at the pharmacy.
