Metformin Hcl 500 mg is a cornerstone medication for managing type 2 diabetes. It works by improving the body's insulin sensitivity and reducing glucose production in the liver, which helps lower blood sugar levels. Metformin HCL is typically prescribed as an oral tablet, taken with meals to minimize gastrointestinal side effects. It is often used in combination with other diabetes medications to achieve optimal blood glucose control. The drug also has potential benefits for weight management and cardiovascular health. Regular monitoring of blood glucose levels and kidney function is essential during treatment to ensure effectiveness and safety.
