Scopoderm TTS

How does it work?

This medicine contains the active ingredient hyoscine hydrobromide, which is a type of medicine called an antimuscarinic (or anticholinergic). It is used to prevent travel sickness. Travel sickness is believed to be a result of the brain receiving conflicting information about what the body senses is happening and what the eyes see is happening. In the inner ear are three fluid filled canals called the vestibular system. These detect changes in the body's position. Motion sickness is thought to occur when the vestibular system sends messages to the brain telling it that the body is being moved around, while the eyes send messages that the body is stationary. Hyoscine hydrobromide is thought to prevent motion sickness by stopping the messages sent from the vestibular system from reaching an area of the brain called the vomiting centre. This area of the brain co-ordinates the vomiting reflex. Hyoscine blocks receptors called muscarinic (or cholinergic) receptors that are found in the vomiting centre. This prevents the vomiting centre from sending nerve messages to the stomach that would normally cause vomiting. Hyoscine needs to be taken before travel to be most effective, as once feeling sick or vomiting has started it is more difficult to control, particularly with tablets that need to be kept down. Hyoscine hydrobromide is available in two forms, as tablets that can be bought without a prescription from pharmacies (eg Kwells, Joy-Rides), and as a skin patch that is only available on prescription (Scopoderm TTS). Hyoscine tablets need to be taken around 30 minutes before travel to be most effective at preventing sickness, and the dose may need to be repeated during long journeys. Scopoderm TTS needs to be applied to the skin behind the ear 5 to 6 hours before travel, or the night before. It can prevent travel sickness for up to 72 hours, but if it is only needed for a shorter time it should be removed at the end of the journey. Read the instructions provided with each individual medicine for more detailed information about doses and administration.
