Supplements and Mebeverine hydrochloride.
Mebeverine hydrochloride, sold under the brand names Colofac, Colofac IBS, Colofac MR, Aurobeverine MR, is a gastrointestinal antispasmodic: it relaxes smooth muscle in the gut wall.
Mebeverine hydrochloride is a gastrointestinal antispasmodic. It is prescribed for irritable bowel syndrome and similar functional gut conditions. The class includes mebeverine, hyoscine, alverine, and peppermint oil. Mechanism varies. Anticholinergic (hyoscine). Direct smooth muscle relaxation (mebeverine). Or calcium channel modulation (peppermint oil). The supplement surface is small because the agents have minimal CYP metabolism. Anticholinergic burden matters most when antispasmodics like hyoscine are combined with other anticholinergic medicines or supplements. Older patients are most sensitive. Peppermint oil enteric-coated capsules count as a supplement in their own right, and have a modest evidence base for IBS symptom relief; Cochrane reviews place the effect size as small but real. Anyone combining a prescribed antispasmodic with peppermint oil should ideally do so on advice rather than randomly.
We have not yet completed an explicit assessment of supplement interactions with Mebeverine hydrochloride in the Distil database. That is different from saying nothing exists. We surface this distinction deliberately: the Distil checker tells you when we have explicitly assessed a pair and when we have not, because both are useful information. If you take Mebeverine hydrochloride alongside a supplement, the checker below will surface anything already in our database, and the missing-item form at the bottom of the page routes uncatalogued pairs into our next curation pass.
What this list does not say. Pairs not flagged here are not implicitly safe. They are either not yet in our database, or fall outside our inclusion scope (food-supplement interactions only; for drug-drug interactions, the BNF is authoritative). Use the checker below to surface any supplement, and submit a missing item if you take something we have not catalogued.
How we grade severity, choose what's in scope, and what we exclude.
Every call on this page is reasoned. We publish the full rubric for severity tiers, the medication inclusion logic, the evidence grades we accept, and what we deliberately leave out. About three thousand words. Worth reading once if you use this tool more than occasionally.

This page checks the pairs you enter. The personalised Distil report goes further:
- the same graded, cited interaction check across your whole stack, not just the pairs you thought to type in
- where your current routine may be leaving you short of your goals
- the evidence-backed compounds worth adding, and the ones worth dropping
It's a paid report: £79, or £49 for the first 25 customers. The interactions check is one section of it, and you can read a real one in full before you buy.
