Colpermin Peppermint Oil Capsules for IBS

Who we can supply: adults 18 and over whose IBS has been diagnosed by a doctor. We don’t diagnose IBS online: if you haven’t been diagnosed, please see your GP. If you’re 60 or over, we can supply Colpermin for IBS you’ve had for a while, but new or changed bowel symptoms need your GP.

See your GP first (don’t use this treatment) if you have: blood in your poo, or black poo; weight loss you can’t explain, or a lump in your tummy or back passage; a change in your bowel habit and you’re 60 or over; tummy swelling or bloating that won’t go away, especially if you’re 50 or over (women); a high temperature, vomiting, or severe pain that keeps getting worse; a family history of bowel or ovarian cancer, or of coeliac or inflammatory bowel disease, and new symptoms.

Our guide to IBS red flags explains why these matter.

This service isn’t suitable if you’re pregnant or breastfeeding. Please speak to your GP or midwife.

Don’t take Colpermin if: you’re allergic to peppermint or menthol; you’re allergic to peanuts or soya. The capsules contain arachis (peanut) oil; you have heartburn or acid reflux that isn’t well controlled, or a hiatus hernia. Peppermint oil can make reflux worse.

Tell the prescriber if you take indigestion remedies (antacids), or medicines that reduce stomach acid such as omeprazole, lansoprazole or famotidine. They can make the capsule coating dissolve too early.
