In his chapter, Cosgrove advises against use of tricyclic antidepressants for children because of "their potentially lethal side-effect profile," the risk of fatal arrhythmia. This caution is extreme in contrast to prevailing practice here, where, with the exception of desipramine, which is avoided, tricyclic antidepressants are widely prescribed for children and regarded as often effective. Although electrocardiogram screening is advisable, the risk is deemed minimal.
