Gliclazide
About Gliclazide
Gliclazide is an oral prescription medication used to help control blood sugar levels in adults with type 2 diabetes. It is prescribed when diet, exercise, and weight loss alone are not enough to keep blood sugar within a healthy range. By keeping your blood sugar under control, this medicine helps prevent long-term damage to your organs.
You will typically take Gliclazide once daily, usually with breakfast or your first main meal of the day. To achieve the best results, it is essential to take it consistently at the same time every day. Combining this treatment with a balanced, low-sugar diet and regular physical activity is key to managing your condition effectively.
While taking Gliclazide, some people may experience mild side effects like a temporary upset stomach or mild headaches. However, you must contact your doctor immediately if you experience signs of severe low blood sugar, such as sweating, shaking, or confusion, or signs of liver damage, like yellowing of your eyes or skin.
Do not take this if you have type 1 diabetes, diabetic ketoacidosis, or severe kidney or liver disease. Before starting Gliclazide, tell your doctor if you have a history of G6PD deficiency or thyroid disorders so they can determine if this treatment is safe for you.
This medicine can interact with several other drugs, including certain painkillers and antifungal treatments, which can increase the risk of low blood sugar. Avoid drinking alcohol while taking this medicine, as it can cause sudden and dangerous drops in your blood sugar. If you are pregnant, planning to become pregnant, breastfeeding, or over 65 years old, talk to your doctor or pharmacist before using this medicine.

Patients Concern
Disease/Condition Glossary
Type 2 diabetes: It is a chronic (long-lasting) condition that keeps the body from utilizing insulin properly. People affected with type 2 diabetes either do not produce enough insulin or are resistant to insulin. Middle-aged or older people are most likely to suffer from type 2 diabetes; hence, it is also known as adult-onset diabetes. Type 2 diabetes symptoms include frequent urination at night, increased thirst, slow wound healing, increased hunger, fatigue and blurred vision. The complications of type 2 diabetes include nerve problems, kidney problems, damaged retina or blindness, loss of limbs, sexual dysfunction, and an increased chance of heart attack or stroke.
FAQs
Gliclazide is used to treat type 2 diabetes mellitus when diet and exercise alone cannot control blood sugar levels.
Gliclazide works by increasing the amount of insulin released by the pancreas. It stimulates insulin secretion from the pancreas and decreases blood sugar levels.
In type 1 diabetes, the body does not produce insulin as the islet cells (insulin-producing cells) in the pancreas are destroyed. In type 2 diabetes, though islet cells are working, the body does not respond to insulin as it becomes resistant to insulin.
Yes, Gliclazide can cause indigestion. Eat a proper well-balanced diet and drink plenty of fluid to avoid it.
In some cases, hypoglycemia or low blood sugar may occur. If you feel your blood sugar level is going down and feel weak, immediately eat sugar candies. It helps balance the blood sugar level in your body.
No. Gliclazide is only prescribed for the treatment of type 2 diabetes also called as 'non-insulin-dependent diabetes'.
The common side effects of Gliclazide are stomach ache or indigestion, feeling sick (nausea), vomiting, and constipation. Most of these side effects do not require medical attention and resolve gradually over time. However, please consult your doctor if you experience these side effects persistently.
The best time to take Gliclazide is before breakfast, or typically 30 minutes before the day's first meal. Taking Gliclazide at this time helps control blood sugar levels throughout the day. However, following your doctor's or pharmacist's specific instructions for taking your medication is essential.
No, Gliclazide and metformin are not the same. They are both used to manage type 2 diabetes, but they work in different ways. Gliclazide belongs to a class of sulfonylureas, whereas metformin belongs to a class of biguanides. Both are effective, but they are prescribed to the patient's needs and conditions based on their mechanism.
Gliclazide can be taken together with metformin. Your doctor may recommend combining these medications based on your individual condition and needs to improve blood sugar control and reduce complication risks. Do not take them together unless your doctor advises you to do so.
Gliclazide is not recommended for use in patients with severe kidney impairment. Please consult your doctor if you have any concerns before using Gliclazide.
No, you should avoid drinking alcohol while taking this medicine. Alcohol increases the risk of experiencing dangerous drops in blood sugar and can mask the warning signs of hypoglycemia. Talk to your doctor or pharmacist if you have concerns about this.

However, it may take a few weeks of consistent use, alongside diet and lifestyle changes, to see a stable improvement in your overall blood sugar patterns. Talk to your doctor if your blood sugar remains high.
Yes, some people may experience mild weight gain when starting this medicine. This is because your body begins to process and store sugar more efficiently instead of losing it through your urine. Managing your calorie intake and staying active can help control your weight. Talk to your doctor or pharmacist for guidance.
You must inform your surgeon or anaesthesiologist that you are taking Gliclazide well in advance. You may need to temporarily stop taking this medicine before your surgery to avoid low blood sugar while fasting. Talk to your doctor for specific instructions.
