Most patients with type 2 diabetes will, in time, need insulin therapy. Starting insulin poses considerable challenges. Also, improving glycemic control with insulin therapy often requires periodic dose adjustments based on glycemic response. Therefore, how to adjust their insulin doses are very important for improvement of glycemic control. Long acting insulin offers the benefit of a more consistent pharmacological dynamic with less hypoglycemia. Therefore, long acting insulin dose adjustments are widely used by patients based on simplified insulin dosing algorithms.
