Apercap contains peppermint oil in a gastro-resistant capsule, which passes through the stomach and releases the oil in the bowel. There it relaxes the gut muscle, easing IBS cramps, bloating and wind. Our guide to peppermint oil for IBS explains how it works.
Colpermin also contains peppermint oil. For other options, see mebeverine vs Buscopan vs alverine and all our IBS treatments.

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 Apercap 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 Apercap if: you’re allergic to peppermint or menthol; 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.
Heartburn, a burning feeling around the bottom and a peppermint taste are the most common. Rarely, a rash or allergic reaction.
Many people notice a difference within a few days. If you’re not better after 2 weeks, see your GP.
Both contain peppermint oil in a gastro-resistant capsule. Check each leaflet for the ingredients: Colpermin contains peanut oil.
The coating protects the oil until it reaches the bowel. Chewing or opening the capsule releases it in the stomach, causing heartburn.
Yes, with mebeverine or fibre, if the prescriber agrees. Avoid indigestion remedies at the same time.
We don’t supply IBS medicines online in pregnancy or breastfeeding. Please speak to your GP or midwife.
