Treatment-emergent adverse events associated with atypical antipsychotics

Atypical antipsychotics provide broad-spectrum effectiveness for the acute and/or preventative treatment of disparate psychiatric disorders. Atypical antipsychotics offer improved efficacy in some psychopathological domains when compared with typical antipsychotics. Notwithstanding, atypicals are not a catholicon and are associated with clinically significant and treatment-limiting side effects (e.g., extrapyramidal symptoms and weight gain).

This article reviews commonly encountered adverse events attributable to the use of atypical antipsychotic agents. This review aims to provide a current overview of common adverse events associated with atypical agents with a particular emphasis on adverse events that frequently lead to treatment discontinuation (e.g., changes in weight, metabolism, extrapyramidal side effects, neuroendocrine changes, blood dyscrasias, and cardiovascular toxicity).

Atypicals are not a catholicon and are associated with clinically significant and treatment-limiting side effects (e.g., extrapyramidal symptoms and weight gain). Improving the utility of these agents requires a familiarity and understanding of the heterogeneous tolerability and safety profiles of atypical agents as well as the therapeutic evidence for their efficacy.
