What is Colpermin?

Colpermin capsules help relieve the symptoms of Irritable Bowel Syndrome (IBS). IBS can be triggered by stress, hormones or certain foods. Symptoms of IBS include stomach cramps, bloating, diarrhoea and constipation. Muscle spasms and inflammation of the intestinal wall cause these IBS symptoms.

How does Colpermin work?

Colpermin contains peppermint oil, which is an antispasmodic. Colpermin capsules have an enteric coating which prevents them from dissolving until they have passed through the stomach and small intestine. When the Colpermin capsule reaches your bowels, it gradually releases peppermint oil which relaxes the muscles of the bowel wall. This prevents painful spasms and helps reduce bloating.

How effective is Colpermin?

Colpermin generally provides effective relief from IBS if used correctly. Colpermin acts locally in your bowels and is not absorbed into your bloodstream.
