How does gliclazide work?
Gliclazide stimulates the pancreas to release more insulin, which helps lower blood sugar levels and manage diabetes effectively.
What is gliclazide used to treat?
Gliclazide is commonly prescribed for:
- Type 2 diabetes (when diet and exercise alone are not enough to control blood sugar levels)
- Preventing complications of diabetes, such as kidney disease, nerve damage, and vision problems
Who can take gliclazide?
Gliclazide is suitable for most adults with type 2 diabetes, as prescribed by a doctor.
Who might not be able to take gliclazide?
Gliclazide may not be suitable if you:
- Have type 1 diabetes or diabetic ketoacidosis
- Have severe liver or kidney disease
- Are pregnant or breastfeeding (unless advised by a doctor)
- Have a history of severe hypoglycaemia (low blood sugar)
Can I take gliclazide if I’m pregnant or breastfeeding?
Gliclazide isn’t usually recommended during pregnancy or breastfeeding. Your doctor may suggest an alternative medication such as insulin.
What if I miss a dose?
If you forget a dose, take it as soon as you remember. If it’s close to your next dose, skip the missed one—do not take two doses at once.
How effective is gliclazide?
Gliclazide is highly effective at lowering blood sugar levels when taken as prescribed, especially when combined with a healthy diet and regular exercise.
What should I do if I take too much?
Taking too much gliclazide can cause dangerously low blood sugar (hypoglycaemia), leading to symptoms such as dizziness, sweating, confusion, or fainting. If you experience these symptoms, eat or drink something sugary immediately and seek medical help if symptoms persist.
What dose of gliclazide is usually taken?
- Starting dose: 40mg to 80mg once daily, usually before breakfast
- Maintenance dose: Up to 320mg daily, divided into one or two doses
- Modified-release tablets: 30mg to 120mg once daily
Your doctor will determine the correct dose based on your blood sugar levels.
