Drug & supplement interaction

Citronella Oil + Ivosidenib

Ivosidenib brand name: Tibsovo.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Citronella Oil and Ivosidenib 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.

Citronella Oil and Ivosidenib

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 Ivosidenib and Citronella 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 Citronella Oil at all — not against Ivosidenib, 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.

No Interaction Found — But Data Suggests Citronella Oil and Ivosidenib May Share a Side Effect

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.

    “Topically, citronella oil is thought to be a skin sensitizer and can potentially cause contact dermatitis. Applying citronella oil 100% to the skin causes irritation or a burning sensation in about 12% of people.”

About Citronella Oil

What is Citronella Oil?

  • Insect and mosquito repellent
  • Aromatherapy and relaxation
  • Topical antimicrobial
  • Fragrance in soaps and household products
  • Skin and hair care products

Citronella oil is an essential oil made from a tropical grass and is best known as a natural insect repellent. Some evidence supports short-term mosquito protection, but it usually does not last as long as conventional repellents like DEET. It is meant for skin or air use, not for swallowing, and can irritate sensitive skin.

Cymbopogon nardus · Poaceae · Leaves and grass (steam-distilled essential oil) · Essential oil, sprays, lotions, candles, diffuser oil

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

Citronella Oil: dosing

There is no official standardized dose for citronella oil. For skin use, it is usually diluted with a carrier oil (such as coconut or almond oil) in commercial repellent products. For aromatherapy, a few drops are added to a diffuser or warm water.Because product strengths vary widely, the best approach is to follow the directions on the label and reapply repellent products as instructed.

Taking Citronella Oil and Ivosidenib Together: Common Questions

Is it safe to take Citronella Oil with Ivosidenib?

Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other.
