Hyoscine hydrobromide is taken to prevent travel sickness (motion sickness). It can also be used to reduce the amount of saliva in your mouth. This can help with symptoms if you're having palliative care or end of life care. Hyoscine hydrobromide comes as patches and tablets that you suck, chew or swallow. It can also given by injection, but this is usually only done in hospital. You can buy the travel sickness tablets and patches at pharmacies. Hyoscine hydrobromide patches and tablets for reducing excess saliva are available on prescription only.
