Metformin SR tablet is a widely prescribed medicine used to control type 2 diabetes and improve blood sugar levels. The term SR (Sustained Release) means the medicine releases slowly in the body, helping maintain stable blood sugar throughout the day.

Doctors commonly prescribe metformin SR for long-term diabetes management, especially for people with insulin resistance or prediabetes.

By controlling blood sugar, metformin helps reduce the risk of complications such as heart disease, kidney damage, and nerve problems.

What Is the Difference Between Metformin and Metformin SR?

Metformin is available in two main forms.
