Pediatric anxiety disorders are highly prevalent and while pharmacological intervention seems to be an effective treatment, the validity of reported adverse side effects remains unclear. <br/><br/>Objective: To analyze the nature of evidence regarding adverse side effects in the pharmacological treatment of pediatric anxiety disorders. <br/><br/>Approach: A search using Google Scholar, PubMed, and PsychInfo was conducted for meta-analyses of pharmacological treatment of pediatric anxiety disorders as well as randomized controlled trials. The focus was on adverse events.<br/><br/>Results and Conclusion: Reportings of a limited number of adverse events were found among resources available to clinician and patient informed sources to inform pharmacological treatment of pediatric anxiety disorders. Only a small fraction of adverse side effects were found in the research literature. This finding raises concerns about making informed decisions to treat pediatric anxiety disorders with pharmacotherapy.
