First do no harm: promoting an evidence-based approach to atypical antipsychotic use in children and adolescents.

OBJECTIVES

To review the evidence for efficacy and metabolic effects of atypical antipsychotics (AAPs), and to propose a metabolic monitoring protocol for AAP use in children and adolescents.

METHODS

A PubMed search was performed to obtain all studies related to efficacy, metabolic side-effects, and monitoring in those less than 18 years of age.

RESULTS

There are no approved indications for AAP use in children and adolescents in Canada. Based on US Food and Drug Administration approvals and a review of randomized controlled trials, we identified 7 indications for AAP use that target specific symptoms in youth including schizophrenia, bipolar I disorder, autism, pervasive developmental disorder, disruptive behaviour disorders (including conduct disorder and ADHD), developmental disabilities and Tourette Syndrome. A wide range of metabolic effects including weight gain, increased waist circumference, dysglycemia, dyslipidemia, hypertension, elevated hepatic transaminases and prolactin levels have been reported. We have developed a proposal for metabolic monitoring that includes anthropometric measurements and laboratory testing at baseline and appropriate intervals thereafter.

CONCLUSION

There is an urgent need for national clinical practice guidelines that provide, not only appropriate treatment algorithms for AAP-use based on evidence, but also address metabolic monitoring and subsequent management of complications in this vulnerable population.
