Abstract

A 30-year-old woman arrived at our hospital with polymorphic ventricular tachycardia and hypothermia. Later, it was found that the cause was an overdose of caffeine exceeding the lethal dose. Although it is common for toxidrome caused by caffeine intoxication to produce hyperthermia, here we report a case of hypothermia.

Keywords: caffeine intoxication; hypothermia; sympathomimetic; toxidrome.
