Metformin is the name of the medication. It comes in the form of a tablet, and should be taken by mouth. It belongs to a class of medications called Biguanide.
This medication is used to treat type-2 diabetes and pre-diabetes conditions. Normally, when you eat food, the body breaks down all of the sugars and starches into a sugar called glucose. This is the basic fuel for the cells in the body. The body needs Insulin to be able to use this sugar for energy. Insulin takes the sugar from the blood into the cells. In type 2 diabetes, either the body does not produce enough insulin or the cells ignore the insulin. This causes glucose to build up in the blood instead of going into cells. It can lead to serious diabetes complications.
Metformin belongs to a group of medications called Biguanides. They work by decreasing the amount of sugar produced by the liver and increasing the amount of sugar absorbed by muscle cells. As a result you get more sugar in the cells and less is in the blood.
This medication comes as a tablet. You should put it in your mouth and swallow it with a glass of water. Do not chew, break or crush it. Swallow it whole.
Tell your physician if you become pregnant. There are not enough studies about this medication in pregnant women. Use the medication during pregnancy only if clearly needed.
