What Buscopan is used for

Buscopan is known as an anticholinergic medicine. It relieves the pain of stomach and bowel cramps by helping your digestive system to relax. It is also used to help relax gallbladder spasms and kidney spasms, and as a diagnostic aid in radiology.
Buscopan reduces the peristalsis (wave-like contractions) of smooth muscle resulting in relief from spasms in certain organs in the digestive system.
Your doctor may have prescribed Buscopan for another reason.
This medicine is available only with a doctor's prescription.
Always consult your doctor or pharmacist if the pain does not improve within 48 hours or if pain worsens after treatment.
