Bottom Line: In a small survey of patients at an urban diabetes center, 1 in 4 reported skimping on their prescribed insulin because of cost and this was associated with poor glycemic control. Insulin is lifesaving for people with diabetes and is listed as an essential medicine by the World Health Organization, which means that it should be available at a price individuals and the community can afford. Insulin prices have increased substantially in the past decade in the United States and so have out-of-pocket prescription costs. Of the 199 patients with type 1 or type 2 diabetes who were prescribed insulin and who completed the survey, 51 (25.5 percent) reported cost-related underuse of insulin. Underuse included using less than prescribed, trying to stretch out insulin, smaller doses, stopping insulin, not filling a prescription or not starting prescribed insulin. More than a third of the patients with cost-related underuse didn't discuss the matter with their doctor. The single-center study may be limited in its broader ability to be generalized but researchers conclude the results highlight an urgent need to address the affordability of insulin.
