Overview
Sunward Metformin 500mg Tablet contains Metformin Hydrochloride 500 mg per tablet and is presented as a tablet. It is supplied in a pack size of 10s.
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
Sunward Metformin 500mg Tablet must only be taken as prescribed by a doctor following a valid prescription or online consultation through DoctorOnCall; take the tablet with or immediately after meals to reduce stomach upset, swallowing it whole with a glass of water rather than crushing or chewing it unless your doctor advises otherwise. Take it at the same time(s) each day as instructed, and do not stop treatment without consulting your doctor even if you feel well.
Dosage
Dosing must follow your doctor’s prescription, but a common starting adult dose is 500 mg once or twice daily with meals, which may be gradually increased by your doctor to a maximum of around 2000-2550 mg per day in divided doses depending on response and tolerance; elderly patients and those with reduced kidney function usually require a lower dose. Never adjust your metformin dose yourself, and inform your doctor promptly if you experience persistent stomach upset or symptoms of low blood sugar.
Shelf Life
Sunward Metformin 500mg Tablet is generally stable for up to 24 to 36 months from the date of manufacture when stored correctly and unopened; always check the expiry date printed on the blister strip or carton before use and do not take tablets beyond this date.

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 Sunward Metformin 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 Sunward Metformin 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.
