Glibenclamide
About Glibenclamide
Glibenclamide is an oral prescription medication used to manage and lower blood sugar levels in adults with type 2 diabetes. It is prescribed when diet, exercise, and lifestyle changes alone are not enough to control blood sugar. By keeping blood sugar in a healthy range, this medication helps prevent serious long-term complications of diabetes.
To get the best results, you must take Glibenclamide consistently every day exactly as your doctor directs. It is typically taken once daily, right before or with your breakfast or your first main meal of the day. Combining this medication with a balanced diet and regular physical activity is essential for managing your condition effectively.
While taking Glibenclamide, some people may experience mild side effects like nausea or a temporary upset stomach. The most common risk is low blood sugar, which can cause shakiness, sweating, or dizziness. If you experience severe symptoms of low blood sugar, yellowing of your skin or eyes, or severe skin rashes, seek medical attention immediately.
Do not take this if you have type 1 diabetes or diabetic ketoacidosis, which is a serious complication of diabetes. It is also important to tell your doctor before starting this medicine if you have kidney or liver problems or a genetic condition called 'G6PD deficiency'. Your doctor will help determine if this medication is safe for you.
Glibenclamide can interact with alcohol, which may cause your blood sugar to drop dangerously low or lead to flushing and headaches. If you are pregnant, planning to become pregnant, breastfeeding, or an elderly individual, consult your doctor before using this medicine, as alternative treatments may be safer.

Habit Forming
Diet & Lifestyle Advise
- Eat meals regularly: Do not skip meals, especially after taking your medication. Skipping meals while taking Glibenclamide greatly increases the risk of low blood sugar.
- Carry fast-acting sugar: Always keep a source of fast-acting sugar with you, such as glucose tablets, fruit juice, or hard candy, to treat sudden low blood sugar symptoms.
- Monitor blood sugar: Check your blood sugar levels regularly as advised by your doctor, especially during times of stress, illness, or changes in exercise.
- Exercise safely: Engage in moderate physical activity daily, but check your blood sugar before and after exercising. Have a carbohydrate snack nearby in case your blood sugar drops during physical activity.

Patients Concern
Disease/Condition Glossary
Diabetes Mellitus type 2: It is a condition in which either the body stops producing enough insulin (the hormone which helps to decrease sugar levels in the blood) or is resistant to insulin action. As a result, excessive insulin is produced. Still, it fails to act on the organs of the body. Type 2 diabetes symptoms include feeling exhausted all the time, feeling thirsty, having blurry vision, and the urge to urinate (pee) more often. Complications of type 2 diabetes include skin infection, eye problems (retinopathy), nerve damage (neuropathy), diabetic foot (foot ulcer), kidney disease (nephropathy), high blood pressure and even stroke. Both low and high blood sugar levels can be dangerous and should be treated as soon as possible. Your HbA1c below 5.7% is normal, 5.7-6.4% confirms the prediabetes stage and 6.5% or greater states diabetes condition.
FAQs
Glibenclamide is used to treat type-2 diabetes, a chronic or lifelong condition affecting how the body processes glucose.
Glibenclamide contains Glibenclamide, which increases the amount of insulin released by the pancreas. It stimulates insulin secretion from the pancreas and decreases blood sugar levels. In a nutshell, it prevents blood glucose levels from rising to very high levels, thus keeping your diabetes under control.
Yes, Glibenclamide can cause constipation. Eat a proper well-balanced diet and drink plenty of fluid to avoid it.
Yes, Glibenclamide is known to cause an upset stomach if taken empty stomach. So, it should be preferably taken with a meal or just after a meal to avoid an upset stomach.
No, Glibenclamide is only prescribed for the treatment for the type 2 diabetes along with a healthy diet and lifestyle. It should not be taken for the treatment of type 1 diabetes.
Hypoglycemia refers to low blood sugar levels. The symptoms of hypoglycemia (low blood sugar) include sweating, feeling shaky or anxious, looking pale, feeling hungry, feeling dizzy, and feeling that your heart is pounding (palpitations). Glibenclamide can cause hypoglycemia. Hypoglycemia can occur if you miss or delay your food, drink alcohol, over-exercise or take other antidiabetic medicine along with Glibenclamide. People with diabetes are advised to keep a quick sugar source like glucose tablets, honey or fruit juice.
It is highly recommended to avoid or strictly limit alcohol while taking Glibenclamide. Alcohol can unpredictably lower your blood sugar levels and increase the risk of severe hypoglycaemia. It can also cause an unpleasant reaction involving flushing, nausea, and a rapid heartbeat. Talk to your doctor for personalised advice.
If you feel symptoms of low blood sugar (shakiness, sweating, dizziness, or confusion), immediately consume 15 grams of fast-acting carbohydrates, such as half a cup of fruit juice, three to four glucose tablets, or hard candy. Check your blood sugar again after 15 minutes. If symptoms persist or worsen, contact emergency medical services or talk to your doctor.
Yes, mild weight gain is a known side effect of medications in this class, as they help your body store glucose more efficiently. Following a balanced diet and regular exercise routine can help manage your weight while taking this medicine. Talk to your doctor or a dietitian for support.
This medication is generally not recommended during pregnancy or breastfeeding, as keeping blood sugar levels stable during these times is crucial, and other treatments like insulin are typically preferred. Talk to your doctor immediately if you are pregnant, planning to become pregnant, or breastfeeding.
Glibenclamide typically begins to lower blood sugar levels within a few hours of taking your first dose. However, it may take several days or weeks of consistent use, alongside dietary adjustments, to see the full benefits in your overall blood sugar control. Talk to your doctor if you do not see improvement.
No, you should not stop taking Glibenclamide without consulting your healthcare provider. Normal blood sugar levels mean the medication is working effectively. Stopping it suddenly can cause your blood sugar to rise quickly again, increasing the risk of long-term complications. Talk to your doctor before making any changes.
If you have a scheduled surgery or medical procedure, inform your surgeon and doctor well in advance that you are taking Glibenclamide. You may need to temporarily stop taking the medication or adjust your dose, especially if you are required to fast before the procedure. Talk to your doctor for specific instructions.
While Glibenclamide does not typically cause kidney damage, it is processed by the kidneys and liver. If you have pre-existing kidney or liver problems, the medication can accumulate in your body, increasing the risk of severe low blood sugar. Rarely, liver damage can occur. Regular blood tests may be needed, so talk to your doctor about monitoring your kidney and liver health.
