Supplements and Paracetamol.

Not yet catalogued in the Distil interactions database. We surface that distinction explicitly.

Paracetamol, sold under the brand names Panadol, Calpol, is an analgesic.

Paracetamol is an analgesic. The class is broad in UK community use, ranging from paracetamol (the dominant agent) through topical preparations and combination products that pair a weak opioid alongside paracetamol or an NSAID. Paracetamol acts centrally rather than at the peripheral COX inhibition that drives NSAID analgesia. That means it does not carry the gastric, renal, antiplatelet, or antihypertensive blunting concerns of the NSAID class. The supplement surface for paracetamol centres on hepatic load. Chronic paracetamol at high doses alongside alcohol, isoniazid, or supplements with significant CYP2E1 or hepatic effect can drive hepatotoxicity. NAC is the antidote in paracetamol overdose. At therapeutic doses, paracetamol is among the cleanest analgesics on interaction profile. The BNF flags only the chronic anticoagulant interaction at high doses, with a small INR effect on warfarin.

We have not yet completed an explicit assessment of supplement interactions with Paracetamol 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 Paracetamol 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 decide

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.

Your whole stack

Want this checked across everything you take?

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.

Something missing?

If a supplement or medication you take isn't in our autocomplete, tell us. We go through what people flag every week and add what's missing.

Thanks, that's logged. We go through flagged items every week.

Distil's interactions database is reviewed and updated every quarter. We grade evidence transparently and publish our methodology, including every database change, at /about/methodology. This tool is information, not a substitute for clinical judgement. If you take medication and supplements together, your GP or pharmacist can review your full regimen against your medical history. If you want a full personalised stack reasoned against this same database, the Distil report is the next step up.
