Clozapine-induced hepatitis confirmed by rechallenge

Abstract

Clozapine is an atypical antipsychotic that holds a unique role in the management of treatment-resistant schizophrenia. Well known side-effects include agranulocytosis and myocarditis but associated hepatic disorders are less familiar and listed under ‘rare or very rare’ by the British National Formulary.1 However, a transient elevation of transaminases has been estimated to affect up to 50% of patients treated with clozapine.2 This article describes a patient with minimally elevated LFTs who subsequently developed symptomatic hepatitis following the initiation of clozapine therapy.
