Can I speak to a doctor or pharmacist about Diamide 5mg/500mg Tablet before I buy it?

What should I do if I notice side effects after using Diamide 5mg/500mg Tablet?

Stop using the product and speak to a doctor or pharmacist about any reaction that concerns you.

How long will delivery take?

Within Malaysia, standard delivery takes 3 to 5 working days. Same-day delivery is available in the Klang Valley for orders placed before 12pm; orders placed after 12pm arrive by the end of the next day. Orders to Singapore are sent as international deliveries and take 5 to 9 working days. A lump-sum shipping and handling fee applies to every overseas delivery and is shown at checkout.

What payment methods can I use?

Customers in Malaysia can pay by FPX online banking, credit or debit card (Visa and Mastercard), and supported e-wallets including Touch ‘n Go eWallet, GrabPay and ShopeePay. FPX and local e-wallets are tied to Malaysian bank and wallet accounts, so if your delivery address is in Singapore, use the payment options displayed at checkout for that address rather than assuming the same list applies.

Can Diamide 5mg/500mg Tablet be delivered to Singapore?

Yes. DoctorOnCall ships to Singapore as an international order dispatched from Malaysia, arriving in 5 to 9 working days with a lump-sum shipping and handling fee. Singapore’s Health Sciences Authority (HSA) allows personal imports of up to three months’ supply of a medicine for your own use or an immediate family member’s, as long as it contains no controlled drugs, psychotropic substances or prohibited items. Keep the product in its original labelled packaging and keep a copy of your prescription or doctor’s letter with it. Quantities above three months’ supply, and medicines containing controlled substances, require prior HSA approval.

Is Diamide 5mg/500mg Tablet registered with the authorities?

Products listed on DoctorOnCall are registered with Malaysia’s Ministry of Health for supply in Malaysia, and each pack carries its MAL registration number. An order delivered to Singapore arrives as a personal import of a Malaysia-registered product; HSA product registration is not required for personal-use quantities, but it is also not the same as a product registered for sale in Singapore. If you need a locally registered Singapore product, buy it from a pharmacy in Singapore.

Who do I contact if there is a problem with my order?

DoctorOnCall’s customer care team handles order, delivery and product queries through the contact channels on the site, including WhatsApp and the online help centre. For deliveries to Singapore, allow more time before chasing an order than you would for a local Malaysian delivery, as the parcel passes through customs clearance and tracking updates can appear later in the journey.

Overview

Diamide 5mg/500mg Tablet is supplied as a tablet, with Glibenclamide 5mg. It is supplied in pack sizes of 10s and 120s.

No prescription is required for this product, as it is a non-prescription medicine. This page is limited to product, safety and handling information.

If you would like guidance before buying, you can speak to a doctor or pharmacist through an online consultation on DoctorOnCall. Orders are dispensed by a registered pharmacist and delivered to your address.

Directions for Use

Diamide tablets should be taken exactly as prescribed by your doctor, typically with meals to reduce the risk of stomach upset and to help align the medicine’s effect with rising blood glucose after eating. It should not be skipped, doubled up, or stopped without medical advice, and blood glucose should be monitored as advised by your healthcare provider.

Dosage

The dose of Diamide is individualised based on blood glucose control, kidney function, and response to treatment, and must be determined and adjusted by your doctor rather than self-adjusted. Doses are usually started low and increased gradually, and it is important to attend regular follow-up appointments so your doctor can review your HbA1c and blood glucose readings and adjust treatment as needed.

Storage Instructions

Store below 30°C in a dry place away from direct sunlight and moisture, keeping tablets in their original packaging until ready to use. Keep out of reach of children.

Side Effects

Nausea or vomiting
Diarrhea
Stomach discomfort or cramps
Metallic taste in the mouth

Acute or unstable conditions that may affect kidney function, such as severe dehydration, serious infection, or shock
Use of iodinated contrast media requiring temporary discontinuation, as advised by your doctor

Drug / Food Interactions

Alcohol may increase the risk of hypoglycaemia and, rarely, lactic acidosis when combined with metformin
Other glucose-lowering medicines, including insulin, may increase the risk of hypoglycaemia if not carefully coordinated
Corticosteroids, thiazide diuretics, and certain other medicines may raise blood glucose and reduce the effectiveness of Diamide
Beta-blockers may mask the warning signs of hypoglycaemia, such as a fast heartbeat
Certain antibiotics and other medicines can alter glibenclamide levels; always inform your doctor of all medicines you take

Quick Tips

Take Diamide with meals as prescribed to reduce stomach upset and hypoglycaemia risk
Always carry a fast-acting source of sugar in case of low blood sugar symptoms such as shakiness, sweating, or confusion
Monitor your blood glucose as advised and keep a record to share with your doctor
Do not skip meals while taking this medicine
Attend regular check-ups to monitor kidney function and overall diabetes control
Seek urgent medical attention if you experience unusual muscle pain, difficulty breathing, or severe tiredness, which could indicate a rare but serious side effect

Relevant Information

Diamide is part of a broader diabetes management plan that should also include regular blood glucose monitoring, a balanced diet, physical activity, and periodic laboratory tests such as kidney function and HbA1c, as directed by your doctor. Because it combines two glucose-lowering mechanisms, careful medical supervision is especially important to balance effective blood sugar control against the risk of hypoglycaemia and other side effects.
