Sunward Metformin 500mg Tablet

Sunward Metformin 500mg Tablet contains metformin hydrochloride, a first-line biguanide medicine used together with diet and exercise to manage blood glucose levels in adults with type 2 diabetes mellitus. It works mainly by reducing the amount of glucose produced by the liver and improving the body’s sensitivity to insulin, helping to lower blood sugar without directly stimulating insulin release, which means it carries a low risk of causing hypoglycaemia when used alone. Because diabetes management requires an accurate diagnosis, individualised dosing, and ongoing monitoring, Sunward Metformin 500mg Tablet is a prescription-only medicine in Malaysia, and DoctorOnCall requires a valid prescription or online consultation with a doctor before this medicine can be dispensed.

Metformin is one of the most widely prescribed and well-studied medicines for type 2 diabetes worldwide and is often the first medicine started after diagnosis, sometimes used in combination with other antidiabetic medicines or insulin as advised by a doctor. Regular blood tests, including kidney function and periodic HbA1c checks, are typically part of ongoing care while taking this medicine, and your doctor will adjust the dose based on your blood glucose control and overall health.

Metformin lowers blood glucose primarily by reducing hepatic glucose production, decreasing intestinal glucose absorption, and increasing peripheral insulin sensitivity so that muscle and fat cells take up and use glucose more effectively; unlike sulfonylureas, it does not stimulate the pancreas to release more insulin, which is why it carries a low risk of causing hypoglycaemia when used on its own.

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.

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.

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.

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.
