It is prescribed to take metformin after meals. You can take the regular tablets 2 to 3 times a day with or after meals. The liquid form is prescribed 1 to 2 times a day with or after meals. In the case of extended-release tablets, the dose is once a day with the evening meal.

When your body can’t use insulin to control blood sugar (type 2 diabetes), biguanides drugs like metformin come to the rescue. These drugs reduce the glucose content you absorb from food and the liver-generated glucose in your body.
