Interaction report

Common Stonecrop and Dextromethorphan HBr, Guaifenesin

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Dextromethorphan HBr, Guaifenesin and Common Stonecrop in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Common Stonecrop at all — not against Dextromethorphan HBr, Guaifenesin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What to actually watch for

What Common Stonecrop Itself Has Been Linked To

This is not an interaction — nothing below involves Dextromethorphan HBr, Guaifenesin. It is the side-effect record for Common Stonecrop on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Common Stonecrop, this list is the first place to look.

Diarrhea / Vomiting Additional detail
“Orally, common stonecrop can cause vomiting and diarrhea when consumed in very large amounts (18).”

Everything above comes from the Natural Medicines adverse-effect record for Common Stonecrop — expand a row for the licensed statement it rests on. We haven’t matched Dextromethorphan HBr, Guaifenesin to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Dextromethorphan HBr, Guaifenesin.

About Common Stonecrop

What is Common Stonecrop?

Wounds and skin irritation
Eczema and other skin conditions
Constipation (laxative use)
Urinary and bladder complaints
High blood pressure (folk use)

Common Stonecrop (Sedum acre) is a small succulent with a long history in European folk medicine, mostly applied to the skin or used as a laxative. There is very little modern scientific evidence to support any of its uses, and the plant can be irritating and may cause vomiting or diarrhea when swallowed, so it should be used with caution and ideally avoided internally.

Sedum acre · Crassulaceae · Above-ground parts (leaves, stems, and flowering tops), used fresh or dried · Fresh plant, dried herb, topical preparations, and rarely teas or tinctures

An interaction check asks whether these two react with each other — it does not ask whether Common Stonecrop is a good idea for someone in your situation. Here is what our Common Stonecrop record says about it on its own.
