Metformin: Uses, Dosage, Side Effects, and More

Metformin is a prescription medication used to manage type 2 diabetes. It works by reducing glucose production in the liver, enhancing insulin sensitivity, and facilitating the body’s more effective use of glucose. Glucophage helps reduce blood sugar levels and may also support modest weight loss in some patients. It is usually taken with meals and is available in immediate-release and extended-release forms.
