Gliclazide is a hypoglycemic antidiabetic oral drug from the group of sulfonylurea. Gliclazide tablets help to aid in the treatment of type 2 diabetes, where the body is unable to produce a significant amount of insulin, causing high blood sugar. Gliclazide is able to stimulate the secretion of insulin in pancreatic beta cells, reducing basal glycemia and glycated haemoglobin. Gliclazide pills can be used as monotherapy aids or associated with other oral antidiabetics, such as Metformin, Acarbos and other Glitazones.

Please use Gliclazide in accordance with your doctors instructions.

Gliclazide 80mg Tablets for Type 2 Diabetes Blood Sugar Control

When diet changes and exercise are no longer enough to keep your levels steady, Gliclazide 80mg tablets offer structured, reliable blood sugar control as part of your wider diabetic care plan.

Gliclazide is a sulfonylurea oral diabetic medication used in adults with type 2 diabetes. It works by encouraging your pancreas to release more insulin, lowering raised glucose levels and supporting day-to-day glucose management. If approved following an online consultation, you can order Gliclazide 80mg tablets from Pharmacy Planet with a clinical review and discreet UK delivery.

How Does Gliclazide Works in Your Body?

Gliclazide belongs to a group of diabetes tablets called sulfonylureas. It works by stimulating the beta cells in the pancreas to release insulin, improving insulin response after meals, supporting better post-meal blood sugar control, and lowering blood glucose levels when your body is still able to produce insulin, but not in sufficient amounts.

Unlike some newer medicines, Gliclazide directly increases insulin release. That means it can be very effective, but it also means meal timing matters. You may also hear about Gliclazide MR (modified release) tablets. These release medicine more slowly through the day. Gliclazide 80mg tablets are the standard release version and are usually taken once or twice daily.

When Are Gliclazide Tablets Prescribed?

Gliclazide 80mg tablets are used in adults with type 2 diabetes when diet and physical activity alone are not enough, when weight loss has not achieved the target glucose levels, when another oral diabetes treatment needs to be replaced, or when additional therapy is required alongside metformin or insulin. They are not used for type 1 diabetes.

How to Take Gliclazide Tablets

Gliclazide 80mg tablets are taken by mouth. Always take this medicine exactly as prescribed by your prescriber.

Starting Dose:

  • Usually 40–80 mg daily (½ to 1 tablet).
  • The dose is adjusted based on blood sugar response.

Usual Daily Range:

  • 40 mg to 160 mg per day.
  • A single dose should not exceed 160 mg.
  • Higher doses are split into two doses and taken with main meals.

Taking Gliclazide with breakfast reduces stomach upset and supports stable blood sugar control. If switching from another diabetes tablet, your prescriber will adjust the starting dose carefully to reduce the risk of low blood sugar.

As Gliclazide increases insulin release, skipping meals can lead to low blood sugar. To reduce risk: eat regular meals, do not skip breakfast, avoid very low-carbohydrate diets unless medically supervised, and limit alcohol intake. The risk of hypoglycaemia may also be higher in older adults and in people with unpredictable meal patterns.

Who Should Not Take Gliclazide Tablets?

Gliclazide 80mg tablets are not suitable if you have type 1 diabetes, diabetic ketoacidosis, severe kidney or liver impairment, are pregnant or planning to become pregnant (insulin is recommended during pregnancy), are breastfeeding (due to the potential risk of neonatal hypoglycaemia), are allergic to sulfonylureas or sulfonamides, are taking miconazole treatment, or have a known deficiency of glucose-6-phosphate dehydrogenase (G6PD). Your prescriber will confirm suitability during your consultation with Pharmacy Planet.

Possible Side Effects of Gliclazide 80mg Tablets

Like all diabetes tablets, Gliclazide can cause side effects.

Common Side Effects:

  • Low blood sugar (hypoglycaemia) — may cause shaking, sweating, fast heartbeat, confusion, dizziness. Symptoms usually improve quickly after taking sugar.
  • Stomach discomfort
  • Nausea
  • Indigestion

Serious Side Effects:

  • Severe hypoglycaemia leading to unconsciousness
  • Yellowing of the skin or eyes (possible liver problem)
  • Severe skin reactions
  • Unusual bruising or bleeding

If symptoms are severe or do not improve, urgent medical attention is required.

Why Do People Choose Gliclazide Tablets?

Many adults with type 2 diabetes use Gliclazide when lifestyle changes alone are not enough. It effectively lowers blood glucose by stimulating natural insulin release, is taken with meals to support steady daily control, offers flexible dosing tailored to individual response, can be combined with metformin or insulin, and is a long-established treatment in type 2 diabetes care. For those who eat regular meals and want reliable blood sugar control, Gliclazide remains a trusted option.

  2. A UK-registered prescriber checks if Gliclazide 80mg tablets are suitable for you and adjusts the dose if required.

Frequently Asked Questions

No. Gliclazide should not be taken without eating. Skipping meals increases the risk of low blood sugar. Always eat a proper meal, especially breakfast, when taking this medicine.

If you feel shaky, sweaty, or dizzy, take fast-acting sugar straight away, such as glucose tablets or sugary juice. Check your levels and seek medical care if symptoms do not improve.

No. Gliclazide 80mg is a standard release tablet and may be taken once or twice daily. Gliclazide MR releases medicine slowly and is usually taken once daily. They are not directly interchangeable.

Some people switch if metformin alone does not control blood sugar properly or causes side effects. Gliclazide stimulates insulin release and may be added or used instead.

Yes, but intense or prolonged exercise can lower blood sugar further. Monitor your levels and carry a quick source of sugar during longer or more strenuous activity.
