Hypoglycemia: New Definitions and Regulatory Implications.

Hypoglycemia is the limiting factor in controlling glucose levels in Diabetes. Rather than being a side effect, hypoglycemia is the mechanism of action for insulin therapy, with a very narrow therapeutic window. Until recently, regulatory bodies listed hypoglycemia only as an adverse effect of therapy; however, one insulin preparation is now recognized and labelled as reducing the risk of severe hypoglycemia. This paper describes internationally agreed upon definitions for hypoglycemia and proposed regulatory approaches for recognition and labeling of diabetes therapies to facilitate personalized care.
