Metformin is the preferred initial pharmacologic agent for the treatment of T2DM.
Once initiated, metformin should be continued as long as it is tolerated and not contraindicated; other agents, including insulin, should be added to metformin.
Consider initiating dual therapy in patients with newly diagnosed T2DM who have A1C >1.5% above their glycemic target.
Intensification of treatment for pts with T2DM not meeting treatment goals should not be delayed.
