Drug & supplement interaction

Mountain Ash + Brentuximab Vedotin

Brentuximab Vedotin brand name: Adcetris.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Mountain Ash and Brentuximab Vedotin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Mountain Ash and Brentuximab Vedotin

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 Brentuximab Vedotin and Mountain Ash 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.

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.

How we checked

Why No Interaction Is Listed for Brentuximab Vedotin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Brentuximab Vedotin is filed under a single classification — cytochrome p450 3a4 (cyp3a4) substrates. Mountain Ash has documented interactions with 1 drug class — the most serious being nephrotoxic drugs (moderate) — and none of Brentuximab Vedotin’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Mountain Ash and Brentuximab Vedotin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

From our pharmacist’s overview on the Brentuximab Vedotin page

“Every entry on this page traces back to a single enzyme. Brentuximab vedotin (Adcetris), an IV treatment for Hodgkin lymphoma and certain other lymphomas, carries a chemotherapy payload the body clears through CYP3A4, and I would treat this list with real care.”

About Mountain Ash

What is Mountain Ash?

Mountain Ash
  • Sore throat and hoarseness
  • Digestive upset and constipation
  • Cough and chest congestion
  • Mild urinary complaints
  • Source of vitamin C in folk medicine

Mountain ash (rowan) is a northern-hemisphere tree whose bright red berries are traditionally cooked into jams, syrups, and teas. There is very little reliable human research to support any medical use, and raw berries contain compounds that can cause stomach upset, so cooking is important. If you want to try it, talk with your pharmacist or doctor first.

Sorbus aucuparia · Rosaceae · Fruit (berries), and sometimes the flowers and bark · Cooked berries, jam or jelly, juice, syrup, tea, tincture

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

Mountain Ash: dosing

There is no established or standardized medicinal dose for mountain ash. It is most often consumed as cooked berries, jam, syrup, or tea rather than as a measured supplement.If you use a commercial product, follow the directions on the label and do not exceed the suggested amount.

Brentuximab Vedotin is filed under 1 classification, and Mountain Ash has documented interactions with 1 drug class — none of Brentuximab Vedotin's classifications are among them.
