The Journal of emergency medicine 2012 SepInsulin glargine is a long-acting insulin that can cause prolonged hypoglycemia when misdosed or overdosed subcutaneously. There are no reports of intravenous overdoses of insulin glargine. We present a case of a patient inadvertently given a large intravenous dose of insulin glargine (100 units) who had an unremarkable course. A 46-year-old woman with a history of type 2 diabetes was found to be hyperglycemic and was mistakenly given an intravenous bolus of 100 units of insulin glargine. She did not become hypoglycemic, did not require parenteral dextrose, and her blood sugar readings stabilized within 3 h. She was admitted and observed for 17 h and discharged without complication. To our knowledge, this is the first report of a significant intravenous insulin glargine administration. This patient had an unremarkable course and recovered without any parenteral glucose. This case, along with prior studies on healthy volunteers, suggests that unlike subcutaneous overdoses, intravenous insulin glargine misdose/overdose may not need prolonged observation; an observation time of 6 h may be sufficient in these patients.
