Use and Out-of-Pocket Costs of Insulin for Type 2 Diabetes Mellitus From 2000 Through 2010

Insulin analogs are molecularly altered forms of insulin.Compared with human synthetic and animal insulin for treatment of type 2 diabetes, short-acting analogs may offer flexible dosing and convenience, long-acting analogs less nocturnal hypoglycemia, 1 but both at greater cost. 2 Because insulin analogs have become increasingly popular, 3,4 we examined trends in insulin use, out-of-pocket expenditures, and severe hypoglycemic events among privately insured US adults with type 2 diabetes from 2000 through 2010.
