To the Editor: Scopolamine, also known as hyoscine, is a selective muscarinic antagonist. Transdermal scopolamine patch (TDSP) is an effective, safe, and convenient method to deliver the drug to reduce symptoms such as postoperative nausea and vomiting (PONV) and motion sickness.1 TDSP is widely used in adults and most of the adverse effects are mild. Although, its use in children is not approved, off-label use is not uncommon due to its ready availability. We report two cases of delirium in young boys after TDSP use, focusing on the lack of safety warning from the manufacturer and the need for emergency department personnel to be alert to the possibility of drug-related acute psychosis.
