Insulins NPH, glargine, and detemir, and risk of severe hypoglycemia among working-age adults*

Abstract

Initiating insulin treatment with detemir, but not with glargine, was associated with a significantly lower risk of severe hypoglycemia compared to NPH, among working-age adults. KEY MESSAGES The comparative safety of modern basal insulins regarding hypoglycemia among the working-age population is unclear. Large reductions in the incidence of severe hypoglycemia were seen among real-life patients who started insulin detemir, as compared to patients who initiated glargine or especially NPH insulin. Given the large amount of patients using insulin, these findings may have considerable clinical consequences at the population level.
