Drug & supplement interaction

Eucalyptus + Belinostat

Belinostat brand name: Beleodaq.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Eucalyptus and Belinostat 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

Eucalyptus and Belinostat

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 Belinostat and Eucalyptus 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 Belinostat

Interactions in our licensed database are recorded against drug classes, not just single drug names. Belinostat is filed under 4 classifications — including cytochrome p450 2c9 (cyp2c9) inhibitors, glucuronidated drugs, p-glycoprotein substrates. Eucalyptus has documented interactions with 7 drug classes — the most serious being amphetamines (moderate), antidiabetes drugs (moderate) and cytochrome p450 1a2 (cyp1a2) substrates (moderate) — and none of Belinostat’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 Eucalyptus and Belinostat 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.

Reported for Eucalyptus but not commonly for Belinostat: seizures, muscle weakness, a fast or pounding heartbeat and sore throat.

Effects for Belinostat come from the ADVERSE REACTIONS section of its FDA label; effects for Eucalyptus come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 347 voluntary FDA FAERS reports for Belinostat that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Belinostat Is Prescribed For, and What Eucalyptus Has Been Studied For

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

Belinostat is prescribed for: Beleodaq (belinostat) injection is approved to treat adult patients with relapsed or refractory peripheral T-cell lymphoma (PTCL) — a fast-growing type of lymphoma (blood cancer) that either came back after treatment or never fully responded to it. This approval is based on how well the cancer responded to the drug, including how long those responses lasted. Whether Beleodaq extends overall survival or improves disease-related symptoms has not yet been established. Continued approval may depend on results from a confirmatory trial.

Eucalyptus has been studied for:

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

    Eucalyptus for cancer

    Although there is interest in using oral eucalyptus for cancer, there is insufficient reliable information about the clinical effects of eucalyptus for this condition.

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 Belinostat on your own; if you are taking Eucalyptus for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Belinostat

This page covers Eucalyptus only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Belinostat page lists 83 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Beer (major), Siberian Cocklebur (major), St. John's Wort (major), Wine (major) and Ashwagandha (moderate).

By severity: 4 major · 73 moderate · 6 minor.

From our pharmacist’s overview on the Belinostat page

“Belinostat (Beleodaq) is chemotherapy for peripheral T-cell lymphoma, and the 83 supplement interactions on record for it deserve real scrutiny, not a skim. Four rate major, and they cluster around two dangers.”

About Eucalyptus

What is Eucalyptus?

Eucalyptus
  • Cough and chest congestion
  • Colds and flu symptoms
  • Stuffy nose
  • Sore throat
  • Minor muscle and joint aches
  • Aromatherapy

Eucalyptus is best known for its strong-smelling oil used in vapor rubs, inhalants, and lozenges to ease coughs and congestion. It may provide mild, short-term relief of cold symptoms, but the oil is toxic if swallowed and must never be taken by mouth undiluted. Talk to a pharmacist or doctor before using it, especially in children, during pregnancy, or while breastfeeding.

Eucalyptus globulus · Myrtaceae · Leaves and essential oil · Essential oil, inhalants/vapor rubs, lozenges, tea, capsules, topical creams

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

Eucalyptus: dosing

There is no official standardized dose for eucalyptus. The right amount depends on the product and how it is used, such as a vapor rub, lozenge, inhalant, or tea.The safest approach is to follow the directions on the product label and not exceed them. Never swallow the concentrated essential oil, and always dilute it before putting it on the skin.

Pharmacist Counseling Corner

Taking Eucalyptus and Belinostat Together: Common Questions

Is it safe to take Eucalyptus with Belinostat?
We do not list a known interaction between Eucalyptus and Belinostat. 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 Eucalyptus and Belinostat have any of the same side effects?
Yes — our sources link each of them separately to 8 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.
Are Eucalyptus and Belinostat used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Eucalyptus in each. That is a conversation for your prescriber, especially if Belinostat is being adjusted to a target.
How was the Eucalyptus and Belinostat combination checked?
Interactions in our licensed database are recorded against drug classes. Belinostat is filed under 4 classifications, and Eucalyptus has documented interactions with 7 drug classes — none of Belinostat'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 Eucalyptus interact with any other medications?
Yes. Eucalyptus has 878 documented drug interactions in our database — Belinostat 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 Belinostat interact with any supplements?
Yes. Belinostat has documented interactions with 83 supplements in our database — Eucalyptus is not one of them. The Belinostat interaction page linked on this page lists every one, ranked by severity.
