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.

Storage Instructions

Store below 30°C in a cool, dry place away from direct sunlight and moisture, in the original packaging until ready to use. Keep this medicine out of the reach and sight of children, and do not share your prescribed tablets with anyone else.

Relevant Information

Because Sunward Metformin 500mg Tablet is a prescription-only medicine used to manage a chronic condition, DoctorOnCall requires customers to complete a valid prescription or online medical consultation before an order can be processed, so that a doctor can confirm the diagnosis, check kidney function where needed, and set an appropriate dose; ongoing follow-up with your doctor is important to monitor blood sugar control and adjust treatment as your condition changes.
