Drug & supplement interaction

Lemon Balm + 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 Lemon Balm 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

Lemon Balm 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 Lemon Balm 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.

Lemon Balm safety at a glance

Lemon Balm overall Use caution Generally well tolerated for short-term use in most healthy adults, but high doses and long-term safety are not well studied.
Pregnancy Avoid Not enough reliable safety data, so it is best avoided during pregnancy unless your doctor advises otherwise.
Breastfeeding Use caution Limited safety information exists, so use caution and talk to your doctor before using while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

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. Lemon Balm has documented interactions with 2 drug classes — the most serious being cns depressants (moderate) and thyroid hormone (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 Lemon Balm 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.

  • Stomach pain / Vomiting / Nausea Additional detail

    Lemon Balm

    “Orally, lemon balm might increase appetite in some patients. Nausea, vomiting, and abdominal pain have been reported rarely and do not seem to occur more often than in patients taking placebo.”

About Lemon Balm

What is Lemon Balm?

Lemon Balm
  • Anxiety and stress
  • Sleep problems
  • Digestive upset
  • Cold sores
  • Restlessness or nervousness

Lemon balm is a gentle, lemon-scented mint-family herb traditionally used to ease stress, support sleep, and calm digestion, and topically for cold sores. Early studies are promising but generally small, so the evidence is limited. It is usually well tolerated for most adults, but pregnant or breastfeeding people should check with a doctor or pharmacist first.

Melissa officinalis · Lamiaceae · Leaves and essential oil · Tea, capsules, tablets, liquid extracts, tinctures, topical creams, and essential oil

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

Lemon Balm: dosing

There is no single standard dose of lemon balm that has been firmly established. The right amount can depend on the form (tea, capsule, extract, or cream) and the reason it is being used.Because products vary widely in strength, the best approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Lemon Balm and Brentuximab Vedotin Together: Common Questions

Is it safe to take Lemon Balm with Brentuximab Vedotin?
We do not list a known interaction between Lemon Balm and Brentuximab Vedotin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Lemon Balm and Brentuximab Vedotin have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Lemon Balm and Brentuximab Vedotin combination checked?
Interactions in our licensed database are recorded against drug classes. Brentuximab Vedotin is filed under 1 classification, and Lemon Balm has documented interactions with 2 drug classes — none of Brentuximab Vedotin's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Lemon Balm interact with any other medications?
Yes. Lemon Balm has 264 documented drug interactions in our database — Brentuximab Vedotin is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Brentuximab Vedotin interact with any supplements?
Yes. Brentuximab Vedotin has documented interactions with 121 supplements in our database — Lemon Balm is not one of them. The Brentuximab Vedotin interaction page linked on this page lists every one, ranked by severity.
