Metformin is usually the first-line medication for type 2 diabetes, as it helps lower blood sugar and improves your body?s response to insulin. Other medications, such as sulfonylureas, DPP-4 inhibitors, SGLT2 inhibitors, or insulin, may be added if needed. Your doctor will select the best option based on your blood sugar levels, overall health, and response to treatment. It is also important to monitor your blood sugar regularly and maintain a healthy diet and exercise routine.
