Scopoderm TTS 1.5mg is a prescription-strength patch for motion sickness prevention or treatment. Every patch is filled with scopolamine, enhancing its efficient delivery through your skin and into the bloodstream for relief that lasts up to 72 hours, or roughly 3 days! Scopoderm patches consist of the active ingredient hyoscine hdyrobromide. This is a type of medication with anticholinergic or antimuscarinic properties often used for travel sickness. Hyoscine hydrobromide blocks the muscarinic or cholinergic receptors and prevents the vomiting reflex a person experiences due to motion sickness.
