What is Colpermin IBS Relief Capsules?

Colpermin IBS Relief Capsules are used to relieve the symptoms of irritable bowel syndrome (IBS), including abdominal cramps, bloating, and trapped wind. Each capsule contains 0.2 ml of peppermint oil, which has natural antispasmodic properties. The capsules are gastro-resistant, meaning they pass through the stomach and release the peppermint oil directly in the bowel where it is most effective.

How Does Colpermin IBS Relief Capsules Work?

Peppermint oil works by relaxing the smooth muscles of the bowel. This reduces spasms that cause cramping pain and discomfort in IBS. The gastro-resistant coating helps prevent the peppermint oil from being released too early in the stomach, reducing the risk of heartburn and ensuring it acts where it is needed most.

Symptoms of IBS

IBS can cause a variety of digestive symptoms, including:

Abdominal cramps or stomach pain that may improve after passing stool
Bloating and excess wind
Diarrhoea, constipation, or a mixture of both
A feeling of urgency or incomplete bowel emptying
These symptoms can flare up due to diet, stress, or other triggers and vary in severity from person to person.

Alternative Treatment Options

Other ways to manage IBS include:

Prescription antispasmodics such as mebeverine (Colofac IBS) or hyoscine butylbromide (Buscopan).
Peppermint oil alternatives like Mintec capsules.
Lifestyle and dietary changes, such as following a low FODMAP diet, reducing caffeine, or increasing fibre gradually.
Over-the-counter medicines for diarrhoea (e.g. loperamide) or constipation (e.g. laxatives).
Stress management, exercise, and good sleep routines.

Can Colpermin IBS Relief Capsules Be Purchased Over the Counter?

Yes. In the UK, Colpermin IBS Relief Capsules are available without a prescription. Pharmacists may ask about your symptoms to ensure the treatment is suitable for you before supply.

Directions for Use

• Adults and children over 15 years: Take one capsule three times daily.
• If symptoms are severe, the dose may be increased to two capsules three times daily.
• Swallow the capsules whole with water, about 30–60 minutes before meals.
• Do not chew or break the capsules, as this can release the peppermint oil too early and cause heartburn.
• Treatment can continue until symptoms improve. If symptoms persist for more than 2 weeks, consult a doctor or pharmacist.
• Not recommended for children under 15.
