Abstract

We report the case of a 43-year-old schizophrenic who sustained, after 12 days of treatment including olanzapine (20 mg.day-1), carbamazepine, levomepromazine and alprazolan, a severe shock with bradycardia (HR: 40 b.min-1), circulatory collapse (SAP: 60 mmHg), hypothermia (T: 27 degrees C), coma and disseminated intravascular coagulation. A significant improvement was obtained with high doses of intravenous glucagon, whereas the normalization of central temperature, atropine, adrenaline and volume loading had been inefficient. Olanzapine, alone of associated with other psychotropics, could cause severe circulatory collapse with hypothermia and coma responding to a treatment including glucagon.
