The use of rescue benzodiazepines in the management of seizures is widely accepted in emergency pediatric practice. They can, however, cause severe side effects, such as respiratory depression. We describe five patients who presented with severe respiratory depression following benzodiazepine administration for seizures with autonomic manifestations. We also discuss the relationship between the complications observed in our patients and the rescue treatment. A reduction in the dosage of benzodiazepines in the setting of epileptic patients with predominant autonomic symptoms may need to be considered.
