Switch-associated adverse events: focus on olanzapine

Abstract

Objectives:

Switching between different antipsychotic therapies is a frequent occurrence in the management of patients with schizophrenia and other psychotic disorders. This paper provides a review of the principles of antipsychotic switching and discusses pharmacological principles underlying adverse events that occur while switching olanzapine to another antipsychotic medication. It offers suggestions for management of switch-associated adverse events in clinical settings.

Conclusions:

Few publications explore olanzapine switch-related adverse events, the underlying pharmacological principles and appropriate switching strategies to minimise the risk of adverse events. There is still a need for further studies to verify existing knowledge and assist in the development of ‘gold standard’ guidelines that outline appropriate switching strategies and duration of the switching process to reduce and avoid adverse events.
