What is Metformin?

Metformin is a type of antidiabetic medicine known as a biguanide. It is used to help control blood sugar levels in people with type 2 diabetes. Metformin reduces the symptoms that are caused by high blood sugar. If you would like to order Metformin, then’s partner pharmacies will be happy to assist you. Metformin is a prescription-only medicine that can be obtained through an online consultation.

What is Metformin used for?

Type 2 diabetes is a form of diabetes that develops when the liver and muscles become resistant to insulin or when the pancreas stops producing enough insulin. A body with a deficiency or absence of insulin has difficulty storing or burning sugar. Hence, in type 2 diabetes blood sugar levels can rise too high, causing symptoms such as thirst, a dry mouth, an increased urge to urinate and fatigue. In the long term, type 2 diabetes can cause damage to blood vessels and organs. Metformin decreases the amount of sugar in the blood, which helps reduce these symptoms and limit the chance of damage to the body. Metformin also has a favourable side effect for people who are overweight: it reduces appetite.

How to use Metformin

Metformin tablets should be swallowed whole with some water, without chewing. If you find they upset your stomach this can be minimised by taking the tablets with or just after food. If you have forgotten to take a dose and it’s almost time for your next scheduled dose, then skip the missed dose and continue your regular dosing schedule. Never take a double dose to make up for the forgotten one.


You can order Metformin online from’s partner pharmacies as regular tablets or as extended-release tablets in doses of 500 mg. Unless otherwise instructed by your doctor, the recommended dose is:

  • Adults: one 500-mg tablet two to three times a day, with a maximum of 3000 mg a day, divided in three doses.
  • Children aged 12 to 18 years: one 500-mg tablet once a day, with a maximum of 2000 mg a day, divided in two to three doses.
