An Unusual Cause of Delirium in a Psychiatric Patient: Abrupt Clozapine Discontinuation

Abstract

Rapid clinical deteriorations have been reported after abrupt discontinuation of clozapine. A 42‐year‐old psychiatric patient presented with ingestion of hand‐disinfectant solutions causing transient impairment of his conscious level. His clozapine therapy was discontinued for a short period of time and he developed delirium with normal results of investigations for underlying organic causes. His delirium resolved rapidly after the reintroduction of clozapine. The withdrawal effects of abrupt discontinuation of clozapine are discussed in this article.
