Common Stonecrop and Macitentan

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 Macitentan 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 Macitentan, 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 Macitentan. 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 read the ADVERSE REACTIONS section of Macitentan’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Macitentan column appears here.

Overlapping uses

What Macitentan Is Prescribed For, and What Common Stonecrop Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Macitentan is a prescription medicine with approved uses on its FDA label. Common Stonecrop is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Macitentan is prescribed for: Macitentan tablets — sold under the brand name Opsumit — are used to treat pulmonary arterial hypertension (PAH, WHO Group I), a type of high blood pressure in the arteries of the lungs. The goal is to slow the disease from getting worse and to lower the chance of being hospitalized because of PAH. In the key clinical study, macitentan was used in adults with mainly moderate-to-severe PAH symptoms. Patients had PAH caused by unknown or inherited causes, connective tissue disorders, or congenital heart disease with repaired shunts.

Common Stonecrop has been studied for:

  • Hypertension studied, not established Common Stonecrop has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Common Stonecrop for hypertension

    Although there has been interest in using oral common stonecrop for hypertension, there is insufficient reliable information about the clinical effects of common stonecrop for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Macitentan on your own; if you are taking Common Stonecrop for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Common Stonecrop

What is Common Stonecrop?

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.

Common Stonecrop: dosing

There is no established or standardized dose for Common Stonecrop. Because it has not been studied in proper clinical trials, safe and effective amounts are simply not known.If you choose to use a commercial product, follow the directions on the label and do not exceed them.
