Toxicology of Medications for Diabetes Mellitus

Medications used to treat diabetes mellitus are heterogeneous, with widely differing safety profiles in therapeutic use and in overdose. Insulin overdose may produce severe and prolonged hypoglycemia. Sulfonylurea poisoning should be treated with octreotide, sparing intravenous dextrose where possible. Acute metformin overdose may lead to life-threatening acidosis with elevated lactate concentrations, which may require hemodialysis. Glucagon-like peptide 1 agonists and dipeptidyl peptidase 4 inhibitors are benign in overdose in diabetic patients but may produce profound hypoglycemia in nondiabetic patients. Euglycemic diabetic ketoacidosis may develop in critically ill patients taking sodium-glucose co-transporter 2 inhibitors.
