Drug & supplement interaction

Niauli Oil + Trabectedin

Trabectedin brand name: Yondelis.

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 Niauli Oil and Trabectedin 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

Niauli Oil and Trabectedin

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 Trabectedin and Niauli Oil 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 Niauli Oil at all — not against Trabectedin, 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.

Niauli Oil safety at a glance

Niauli Oil overall Use caution Generally used topically or by inhalation when diluted, but it is a potent essential oil that can irritate skin and is toxic if swallowed in large amounts.
Pregnancy Avoid Safety is not established, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety data, so avoid use while breastfeeding.

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

What to actually watch for

No Interaction Found — But Data Suggests Niauli Oil and Trabectedin 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.

  • Vomiting / Nausea / Diarrhea reported in 8.8% of FDA reports for Trabectedin Additional detail

    Niauli Oil

    “Orally, niauli oil can cause nausea, vomiting, and diarrhea (2). The consumption of amounts greater than 10 grams can cause hypotension, circulatory disorders, collapse, and respiratory failure (18).

    Topically, it can cause glottal spasm, bronchospasm, and respiratory failure when applied to facial and nasal areas of infants and small children (2,18).”

    Trabectedin

    Listed in the ADVERSE REACTIONS section of the FDA label for Trabectedin, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Niauli Oil but not commonly for Trabectedin: wheezing and low blood pressure.

Effects for Trabectedin come from the ADVERSE REACTIONS section of its FDA label; effects for Niauli Oil come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 2,260 voluntary FDA FAERS reports for Trabectedin 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.

From our pharmacist’s overview on the Trabectedin page

“People receiving trabectedin (Yondelis), an infused chemotherapy for soft tissue sarcoma and some ovarian cancers, often reach for supplements to boost energy or support a stressed liver, and that instinct is exactly where the trouble sits. This list warrants real caution.”

About Niauli Oil

What is Niauli Oil?

  • Coughs and congestion
  • Sore throat
  • Minor skin infections
  • Wound care (traditional)
  • General antiseptic use

Niaouli oil is an essential oil from the Melaleuca quinquenervia tree, often used in folk medicine and aromatherapy for respiratory complaints and as an antiseptic. Solid human evidence for these uses is limited, and like other concentrated essential oils it must be diluted and never swallowed without medical guidance. Talk to a pharmacist or doctor before using it, especially in children, during pregnancy, or while breastfeeding.

Melaleuca quinquenervia · Myrtaceae · Leaves and twigs (steam-distilled into essential oil) · Essential oil, diluted topical blends, inhalation/diffuser products, some throat lozenges and cough preparations

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

Niauli Oil: dosing

There is no officially established or standardized dose for niaouli oil. Effective and safe amounts have not been well defined in human studies.For topical use, essential oils are typically diluted to a low percentage in a carrier oil; for inhalation, only a few drops are used in a diffuser or bowl of hot water. The safest approach is to follow the directions on a finished product's label and not to apply the oil undiluted.Do not take niaouli oil by mouth unless a qualified healthcare professional advises it.
