Hyoscine butylbromide is an antispasmodic medicine which is taken to relieve cramps in the stomach, intestines or bladder. In particular, it helps to ease bloating and the spasm-type pain that can be associated with irritable bowel syndrome and diverticular disease. It works by relaxing some of the muscles in your gastrointestinal and urinary systems.
Hyoscine butylbromide is available on prescription. You can also buy it from a pharmacy, without a prescription, to relieve the symptoms of irritable bowel syndrome, providing your symptoms have previously been diagnosed by a doctor.
There is also a medicine called hyoscine which is taken to prevent travel sickness. There is more information about this in a separate medicine leaflet called Hyoscine for travel sickness.
