Diabetmin 500mg Tablet contains Metformin Hydrochloride 500mg and is presented as a tablet. It is supplied in pack sizes of 100s and 20s.
It is classified as a non-prescription medicine, so no prescription is needed to order it. Under Malaysian rules for medicine information, this page carries product, safety and handling information only.
You can consult a doctor or pharmacist online on DoctorOnCall about this product before or after you order. Every order is checked by a registered pharmacist before it is delivered. Always read the label and the leaflet supplied with the pack.
Directions for Use
Diabetmin 500mg Tablet should be taken exactly as prescribed, generally with or right after meals to reduce the chance of stomach upset. Doctors often start treatment with a lower frequency and gradually increase it to help the body adjust, so patients should follow their individual schedule rather than assuming a fixed regimen. Tablets should be swallowed whole with water; do not crush or chew unless specifically advised by the doctor.
Dosage
The dose of Diabetmin 500mg Tablet is set individually by the prescribing doctor, commonly starting at a low frequency such as once or twice daily with meals and increased gradually over one to two weeks based on blood glucose response and tolerability. The maximum daily dose and any further adjustments should only be decided by the doctor after reviewing blood glucose control and kidney function.
Storage Instructions
Store below 30°C in a dry place, away from direct light and moisture, and keep tablets in their original packaging until needed. Keep out of the sight and reach of children.
Side Effects
Nausea or vomiting
Diarrhea
Stomach discomfort or cramps
Metallic taste in the mouth
Loss of appetite
Weight loss (in some cases)
Contraindications
Known hypersensitivity to metformin
Moderate to severe kidney impairment, as assessed by the prescribing doctor
Acute conditions with risk of altered kidney function, such as severe dehydration, serious infection, or shock
Unstable or acute decompensated heart failure
Conditions predisposing to tissue hypoxia, such as acute heart attack or severe respiratory failure
Planned use of iodinated contrast dye for imaging, unless timed by the doctor around the procedure
Drug / Food Interactions
Iodinated contrast media used in certain imaging scans — Metformin may need to be temporarily stopped around the procedure on your doctor’s advice
Alcohol — excessive intake increases the risk of lactic acidosis, especially with liver problems or fasting
Certain diuretics, corticosteroids, and other medicines that can affect kidney function or blood glucose control
Other glucose-lowering medicines or insulin — combined use may increase the risk of low blood sugar and requires monitoring
Take with food as directed, as this reduces gastrointestinal side effects

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.
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.
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.
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.
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.
