Abstract
The value of sulphonylureas in the long-term treatment of type II diabetes has been questioned. The potential benefits of an antidiabetic drug must be carefully weighed against the risk of developing hazardous adverse effects like hypoglycaemia. We present drug-induced hypoglycaemia in a 77-year-old Pakistani male who had hypertension, type II diabetes and renal parenchymal disease (grade I), presented to the emergency department complaining of a 1-day history of fever, loose motions and drowsiness. His fever was low grade, intermittent, and not associated with rigors and chills. He had four episodes of watery stools for 1 day, with no associated vomiting but with drowsiness. He was aphasic, unable to walk and did not recognize his family members. The patient was taken to his local doctor who found him to be hypoglycaemic, with a blood sugar of 45 mg/dl. He was managed with intravenous (IV) dextrose and referred to the hospital. Hypoglycaemia is perhaps the most widespread and underreported complication of oral hypoglycaemic agents and may lead to overwhelming morbidity and mortality. Patient evaluation and proper counselling may help in identifying patients at greatest risk and avoid complications associated with these commonly prescribed drugs.
