Abstract

Our clinical experience that lithium is an agent used infrequently for self-poisoning was investigated. The rate at which such overdoses occurred was determined from hospital records. A retrospective casenotes study then compared overdose rates in patients taking lithium versus patients on antidepressant medication. A low rate of lithium overdoses was identified, and this appeared to be due to patients on lithium rarely taking overdoses rather than their choice of agent.
