You should definitely run this by their pediatrician, but likely not. The active ingredient in this medication is Hyoscine, also known as Scopolamine. I was reading a leaflet on Scopex and it states "Due to the risk of provoking hyperpyrexia it should not be given to patients, especially children where the ambient temperature is high." It also says "Use with caution in children, geriatric patients, patients with diarrhoea, fever, and in conditions characterised by tachycardia". Source
