Overview
Novugen Diaglycon MR 30mg Tablet contains gliclazide 30mg in a modified-release (MR) formulation, a sulfonylurea medicine used to help control blood glucose levels in adults with type 2 diabetes mellitus. It is generally prescribed when diet, exercise, and weight management alone are not enough to achieve adequate blood sugar control, and works by stimulating the pancreas to release more insulin in response to meals.
Novugen Diaglycon MR 30mg Tablet is a prescription-only medicine in Malaysia. A doctor’s assessment is required before starting treatment, including a review of your kidney and liver function, other medical conditions, and other medicines, because sulfonylureas like gliclazide can cause low blood sugar (hypoglycaemia) if not dosed and monitored appropriately. Through DoctorOnCall, customers can have an online consultation with a doctor who will assess suitability and issue a prescription before this medicine is dispensed.
How it Works
Gliclazide belongs to the sulfonylurea class of medicines and works by binding to specific receptors on the pancreatic beta cells, stimulating them to release more insulin, particularly in response to rising blood glucose after meals. The modified-release formulation allows gliclazide to be released gradually over the day, supporting more consistent blood glucose control with once-daily dosing compared with immediate-release formulations.
Directions for Use
Take Novugen Diaglycon MR 30mg Tablet exactly as prescribed by your doctor, typically once daily with breakfast or the first main meal of the day, swallowed whole with water. Do not crush or chew the tablet, as this can affect the modified-release mechanism and how the medicine is absorbed. Eating a meal after taking this tablet is important to reduce the risk of low blood sugar.
Dosage
The starting dose and any subsequent adjustments are determined by your doctor based on your blood glucose readings, HbA1c levels, kidney and liver function, and response to treatment; the dose must not be self-adjusted. Your doctor may periodically review your dose and may combine this medicine with other diabetes medicines or insulin depending on your overall blood sugar control. Missing a dose should be discussed with your doctor or pharmacist rather than doubling the next dose.
Shelf Life
Do not use this medicine beyond the expiry date printed on the packaging. Your pharmacist can confirm the exact expiry date at the time of dispensing.
Storage Instructions
Store below 30°C in a dry place away from direct sunlight and moisture, keeping the tablets in their original packaging until use. Keep out of the sight and reach of children at all times.

- Should not be started, stopped, or dose-adjusted without your doctor’s guidance.
Drug / Food Interactions
- Alcohol can increase the risk and severity of hypoglycaemia and should be limited or avoided as advised by your doctor.
- Certain medicines such as some antifungals, antibiotics, and NSAIDs can increase gliclazide’s blood-sugar-lowering effect, raising hypoglycaemia risk.
- Corticosteroids, some diuretics, and certain hormonal medicines can raise blood sugar and reduce gliclazide’s effectiveness.
- Other diabetes medicines, including insulin, can have an additive blood-sugar-lowering effect; dose adjustments may be needed if used together.
- Inform your doctor of all other medicines and supplements you are taking to help manage these interactions safely.
