What is Colpermin?

Colpermin capsules are used to relieve the symptoms of irritable bowel syndrome (IBS). IBS can be triggered by stress, hormones or foods and includes symptoms such as stomach cramps, bloating, diarrhoea or constipation. It is often related to abnormal muscle contraction and inflammation of the intestinal wall.

How does Colpermin work?

Colpermin contains peppermint oil, which is a natural antispasmodic. The capsules have an enteric coat which prevents them from dissolving until they have passed through the stomach and upper intestine into the lower intestine. Here, the capsules gradually release the peppermint oil which relaxes the muscles of the bowel wall, preventing painful spasms and easing bloating.

How effective is Colpermin?

Results differ from patient to patient, but Colpermin generally provides effective relief from IBS if used correctly.
