Even though drug-induced hypoglycemia is a rare event in the general population, it occurs more frequently in the elderly and in diabetic patients and thus should be considered in the differential diagnosis of altered mental status in these patient groups. In this case study, the authors describe a 91-year-old woman who was taken to the emergency department because of decreased consciousness while on a drug regimen that included once-daily triamterene-hydrochlorothiazide and twice-daily, double-strength trimethoprim-sulfamethoxazole (TMP-SMX). On arrival at the hospital, the patient had a plasma glucose value of 34 mg/dL along with an elevated creatine kinase level and a small tongue laceration. She was treated with a 50-mL ampule of 50% dextrose solution intravenously. She regained conti-4.jSciousness within 5 minutes after treatment and had a glucose: Aeyel of 210 mg/dL 10 minutes later. The patients rapid re,. spfans.p-|o dextrose administration indicated hypoglycemia, the result of an overdosage of TMP-SMX combined Wth the.jeffects of her thiazide diuretic. The authors caution phyisiaris-il keep in mind the decreased renal function of elderly:patients its; when adjusting medication doses and to watch for potenti-al-effects when combining medications in this patient group.
