Drug-induced hypoglycemia presenting as acute mountain sickness, after mistaking acetohexamide for acetazolamide.
Acute mountain sickness (AMS) can present with a wide variety of symptoms in unacclimatized persons who rapidly ascend to altitudes > 2500 m. The clinical manifestations of drug-induced hypoglycemia, including adrenergic and neurologic symptoms, have significant overlap with the AMS symptom complex. These similarities can lead to confusion in the diagnosis of hypoglycemia versus AMS, particularly for diabetics ascending to altitude. A case is described in which the oral hypoglycemic agent acetohexamide, instead of acetazolamide, was mistakenly self-administered for the prophylaxis and treatment of altitude illness. Improper self-medication by travelers in remote areas may be more common than is currently recognized.
