Type 2 drug

Metformin is a type 2 diabetic drug, and helps diabetics to respond normally to insulin. Like most diabetic drugs, the ultimate goals of Metformin are to lower blood sugar to a normal level and maintain this level. Metformin can be used in conjunction with other diabetic drugs, and diabetics should also use diet and exercise to help control their condition.

Transcript

Metformin is a widely prescribed drug for treating type 2 diabetes. Metformin is often the first medication that will be prescribed to people with type 2 diabetes. Metformin helps to lower blood glucose levels by reducing the amount of glucose produced and released by the liver, and by increasing insulin sensitivity.

Metformin is usually taken at meal times but your doctor will advise you when and how often to take metformin. Metformin may be available in tablet form or in sachets of powder.

The NHS state that Metformin may not be suitable for everyone. People at risk of lactic acidosis should discuss suitability of the drug with their doctor.

More common side effects of metformin include:

  • Nausea
  • Stomach pains
  • Loss of appetite
  • Changes in bowel movements
  • Changes in taste

Initial side effects may naturally alleviate after the first few weeks. Metformin is also available in a modified release form which may help patients that are having continued trouble in tolerating side effects of metformin.

How Metformin Works

Metformin helps the body to control blood sugar in several ways. The drug helps type 2 diabetics respond better to their own insulin, lower the amount of sugar created by the liver, and decreasing the amount of sugar absorbed by the intestines.

When taken alone, Metformin is unlikely to cause hypoglycemia or weight gain, but when taken in conjunction with insulin or a sulfonylurea both of these side effects are more likely.
