The bottom line No known interaction

We found no known interaction between Myrtle and Tirbanibulin 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.

Myrtle and Tirbanibulin

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 Tirbanibulin and Myrtle 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 Myrtle at all — not against Tirbanibulin, 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.

What to actually watch for

What Myrtle Itself Has Been Linked To

This is not an interaction — nothing below involves Tirbanibulin. It is the side-effect record for Myrtle on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Myrtle, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on Additional detail

    “Orally, consumption of very large amounts of undiluted myrtle leaf oil might lead to respiratory failure and collapse (18).

    Topically, facial contact with myrtle oil preparations may cause glottal or bronchial spasm, asthma-like attacks, or respiratory failure in infants and children (18).”

Everything above comes from the Natural Medicines adverse-effect record for Myrtle — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Tirbanibulin’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Tirbanibulin column appears here.

See Every Supplement That Interacts With Tirbanibulin

This page covers Myrtle only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Tirbanibulin page lists 3 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Dimethylsulfoxide (dmso) (moderate), Turpentine Oil (moderate) and Alchemilla (minor).

By severity: 2 moderate · 1 minor.

From our pharmacist’s overview on the Tirbanibulin page

“Topical DMSO is the one to know about if you use tirbanibulin (Klisyri), the ointment prescribed for actinic keratosis on the skin. DMSO can drive other topical drugs deeper through the skin, which could amplify both the medication's effect and its irritation right where it's applied.”

About Myrtle

What is Myrtle?

  • Coughs and respiratory congestion
  • Digestive upset
  • Antimicrobial and wound care
  • Skin conditions
  • Urinary complaints

Myrtle (Myrtus communis) is a Mediterranean shrub used traditionally for respiratory, digestive, and skin complaints. Modern research is mostly limited to laboratory and small studies, so its benefits in people are not well proven. Use cautiously, follow product labels, and talk to your pharmacist or doctor first—especially since the essential oil should never be swallowed.

Myrtus communis · Myrtaceae · Leaves, berries, flowers, and essential oil · Tea, capsules, extracts, essential oil, topical preparations

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

Myrtle: dosing

There is no well-established standard dose for myrtle. Amounts used in traditional practice and studies vary widely depending on the form—tea, extract, capsule, or oil.Because products differ in strength and quality, the safest approach is to follow the directions on the product label and not exceed them.

About Tirbanibulin Topical

What Is Tirbanibulin Topical Used For?

Brand name: Klisyri

Klisyri (tirbanibulin 1% ointment) is applied directly to the skin to treat actinic keratosis — rough, scaly patches caused by years of sun damage that can sometimes turn into skin cancer if left untreated. It is approved for use on the face or balding scalp in adults.

Klisyri is applied to the entire affected treatment area (up to a 100 cm² patch) rather than to individual spots, an approach called field treatment.
