Hyoscine hydrobromide is a travel sickness (motion sickness) medicine that belongs to a group of medicines called anticholinergics or antimuscarinics.
It's thought to work by affecting your inner ear and your brain to control vomiting. It also relaxes the muscles in the walls of your stomach.
Hyoscine hydrobromide comes as patches that you stick to your skin and tablets that you suck, chew or swallow.
It can also be given by injection, but this is usually only done in hospital. It is given to reduce the amount of saliva in your mouth which can help with symptoms if you're having palliative or end of life care.
You can buy the tablets and patches at pharmacies.
Information
Hyoscine hydrobromide is not the same as hyoscine butylbromide, better known as Buscopan.
