The bottom line No known interaction

We found no known interaction between Cajeput Oil and Crizotinib in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Cajeput Oil and Crizotinib

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 Crizotinib and Cajeput 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.

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.

Cajeput Oil overall Use caution Generally used topically or for inhalation in diluted form; it can irritate skin and should not be swallowed.

How we checked

Why No Interaction Is Listed for Crizotinib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Crizotinib is filed under 5 classifications — including qt interval-prolonging drugs, cytochrome p450 3a4 (cyp3a4) inhibitors, p-glycoprotein substrates. Cajeput Oil has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and cytochrome p450 2d6 (cyp2d6) substrates (moderate) — and none of Crizotinib’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 Crizotinib’s Own FDA Label Lists

This is not an interaction — none of it involves Cajeput Oil. These are the most notable effects listed in the ADVERSE REACTIONS section of Crizotinib’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Muscle weakness Worth acting on
  • Trouble swallowing Worth acting on
  • Unsteadiness Worth acting on
  • A slow heartbeat Worth acting on
  • Blood clots Worth acting on
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on
  • A low platelet count Worth acting on
  • Shortness of breath Worth acting on
  • A low white blood cell count Worth acting on

Showing the 10 most notable of 36 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Crizotinib. Read the label on DailyMed › Where a percentage is shown, it is the share of 12,638 voluntary FDA FAERS reports for Crizotinib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Cajeput Oil’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cajeput Oil side to compare — that is a limit of the record, not a statement that Cajeput Oil has no side effects.

From our pharmacist’s overview on the Crizotinib page

“Grapefruit tops my worry list for crizotinib (Xalkori), a targeted pill for ALK-positive lung cancer. It blocks the enzyme (CYP3A4) that clears crizotinib, letting levels climb and side effects with them, and it is one of eight major-rated entries among the 157 supplements and herbs on file for this drug.”

About Cajeput Oil

What is Cajeput Oil?

Cajeput Oil
  • Muscle and joint aches
  • Cough and congestion
  • Minor skin irritation
  • Insect repellent
  • Aromatherapy

Cajeput oil is an aromatic essential oil traditionally used for aches, congestion, and minor skin complaints, but solid human evidence for these uses is limited. Like other essential oils, it should never be swallowed and should be diluted before applying to skin; consult a pharmacist or doctor before use, especially in children, pregnancy, or breastfeeding.

Melaleuca cajuputi · Myrtaceae · Essential oil distilled from the leaves and twigs · Essential oil, diluted topical rubs, inhalants/balms, aromatherapy blends

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

Cajeput Oil: dosing

There is no official, standardized dose for cajeput oil, and no proven safe amount for taking it internally. For topical or aromatherapy use, the general practice is to dilute a small amount of the essential oil in a carrier oil before applying to the skin.Because products differ in strength, follow the directions on the label and do not exceed them.
