Insulin can be a life-saving drug, but high drug costs can lead persons with diabetes to stop taking or ration their insulin. Currently, there is a wide range of insulin out-of-pocket cost caps being used by states and payers.

This Study Snapshot summarizes research from Carrie McAdam-Marx, Professor in the College of Pharmacy at the University of Nebraska Medical Center, Natalia Ruiz-Negron, Research Assistant Professor in the College of Pharmacy at the University of Utah, who examined the association between insulin out-of-pocket costs and the use of insulin and non-insulin diabetes medications, as well as the association with other diabetes-related outcomes. Study findings suggest gaps in insulin adherence are likely to occur for out-of-pocket costs greater than $35 per 30-day supply.
