Colpermin product information

Colpermin capsules contain peppermint oil which relaxes gut wall spasm. It helps to relieve stomach cramps caused by IBS by relieving pain of the gut and releasing gas that cause you to feel bloated.

Along with taking Colpermin, some simple lifestyle measures can also help to control symptoms of IBS. Please visit the condition medical information page.

How to take

The usual dose for IBS is to take one capsule 3 times daily. If symptoms are severe, it can be increased up to 2 capsules 3 times daily. You should swallow the capsule whole. It should not be taken immediately after food and with any indigestion remedies as its absorption can be impaired. 

The capsules can be taken for 1 to 2 weeks until the symptoms resolve, and may be continued up to 2-3 months if symptoms persist.

Side effects of Colpermin

Like all medicines, Colpermin can cause some side effects, although not everyone gets them.

Colpermin can cause occasional heartburn or acid reflux and nausea or vomiting. Side effects are usually mild but if you are concerned about any of these, you should speak to your doctor or pharmacist for more advice.

If you experience severe allergic reaction to peppermint oil with symptoms such as rash, headache, slow pulse rate and shaking, you should stop taking Colpermin and seek urgent medical advice. The side effects are more likely to occur if taken with alcohol.

For a full list of side effects, please refer to the patient information leaflet attached below.
