Contributor: Dylan Luyten, MD Educational Pearls: Insulin related hypoglycemia can vary from a brief transient effect from short-acting forms (i.e. insulin lispro) to prolonged from long acting (i.e. insulin glargine), and will require different treatment and/or observation Of oral glycemic agents, sulfonylureas are a common culprit while metformin is rarely a cause Sulfonylureas also deserve attention because in pediatric patients, they can be lethal even with a single ingestion, but also can cause severe hypoglycemia in adults Hypoglycemia in non-diabetics usually occurs in the malnourished, or in those with liver or adrenal disease References Klein-Schwartz W, Stassinos GL, Isbister GK.
