Indicated in acute spasm, as in renal or biliary colic, in radiology for differential diagnosis of obstruction and to reduce spasm and pain in pyelography, and in other diagnostic procedures where spasm may be a problem (e.g. gastroduodenal endoscopy).


Hyoscine butyl bromide relieves the pain by acting on the muscle spasm which causes the pain. Its anticholinergic action exerts a smooth-muscle relaxing/spasmolytic effect. It also binds to nicotinic receptors, which induces a ganglion-blocking effect.


It may interact with anti-emetic (domperidone, metoclopramide), bronchodilator (salbutamol), anti-arrhythmic (quinidine, disopyramide), anti-Parkinson (amantadine), anti-cholinergic (tiotropium, ipratropium), anti-psychotic (haloperidol, fluphenazine), opiate analgesic (codeine), anti-depressant (amitriptyline), and antihistamines.

Side Effects

Anticholinergic side effects of hyoscine butylbromide are generally mild: Dry mouth, Constipation, Blurred vision, and Fast heart rate.
