Suicide attempt with a very high dose of quetiapine

Abstract

Although there are reports in the literature about quetiapine intoxication, information about very high dose quetiapine intoxication is limited. We present a case report about an extreme overdose of quetiapine (18,000 mg.) together with alcohol taken by a 21-year-old female as a suicide attempt. The symptoms associated with intoxication, including seizure and arrhythmia are discussed. Despite the very high dose of quetiapine, the patient recovered completely without residual symptoms.
