All metformin products not created equal?

Our clinical staff has recently received inquiries regarding the medication products that contain Metformin. As this is a very commonly used diabetes medication and there are various forms of available, I wanted to share the information with you.

Metformin was introduced in Europe in the 1950’s and the Food and Drug Administration (FDA) approved its use in the U.S. in December 1994. In general, metformin products:

  • Decrease the amount of glucose released by the liver
  • Decrease intestinal absorption of glucose
  • Improve insulin sensitivity
  • Improve glucose utilization in skeletal muscle and adipose tissue.

The main differences in the various products involve the chemical coating of the products and their location of action. Click here for more detailed information on the specific functions of different metformin products. If you have questions about the metformin product you take, contact your physician or diabetes educator. Please share any concerns or questions with our staff.
