Supplements and Carvedilol.

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

Carvedilol, sold under the brand name Eucardic, is a beta-blocker: it reduces heart rate and cardiac output by antagonising beta-adrenergic receptors.

Carvedilol is a beta-blocker. The class reduces heart rate and cardiac output. Depending on receptor selectivity, it can also carry bronchospasm risk in patients with asthma. Cardiac-selective agents (bisoprolol, atenolol, nebivolol) carry lower bronchospasm risk than the agents that block both receptors (propranolol, carvedilol). The supplement surface is mostly quiet. The class is not strongly CYP metabolised in most cases, so the CYP interactions seen with statins and SSRIs do not apply here. Additive bradycardia from CoQ10 is small and clinically minor. Additive hypotension from beetroot, hibiscus, garlic, and magnesium at higher doses can stack on top. The signal to watch in the early weeks of any agent in this class is a resting heart rate below 50 or symptomatic dizziness on standing. Both warrant a dose review with the GP.

We have not yet completed an explicit assessment of supplement interactions with Carvedilol 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 Carvedilol 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.

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.
