Drug & supplement interaction

Perillyl Alcohol + Tirbanibulin

Tirbanibulin brand name: Klisyri.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 13, 2026

The bottom line No known interaction

We found no known interaction between Perillyl Alcohol 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. 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

Perillyl Alcohol 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 Perillyl Alcohol 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 Perillyl Alcohol 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.

Perillyl Alcohol safety at a glance

Perillyl Alcohol overall Use caution It is mostly an investigational compound with limited human safety data outside clinical trials.

Pregnancy Avoid There is not enough safety information, so it is best avoided during pregnancy.

Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid use.

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 Perillyl Alcohol and Tirbanibulin 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.

Itching Additional detail
Perillyl Alcohol
“Orally, perillyl alcohol can cause adverse effects including gastrointestinal upset, reflux, nausea, diarrhea or constipation, fatigue, and headache. In high doses, perillyl alcohol has been associated with single reports of acute pancreatitis, increased bilirubin, increased white blood cell count, and hypokalemia.

Topically, perillyl alcohol has been rarely reported to cause a mild rash or tenderness.”

Tirbanibulin

Listed in the ADVERSE REACTIONS section of the FDA label for Tirbanibulin. Read the label on DailyMed ›

Reported for Perillyl Alcohol but not commonly for Tirbanibulin: stomach upset, low potassium, yellowing of the skin or eyes and pancreatitis.

Effects for Tirbanibulin come from the ADVERSE REACTIONS section of its FDA label; effects for Perillyl Alcohol come from the Natural Medicines adverse-effect record, quoted above. 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 Tirbanibulin Is Prescribed For, and What Perillyl Alcohol Has Been Studied For

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

Tirbanibulin is prescribed for: 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.

Perillyl Alcohol has been studied for:

Actinic keratoses studied, not established Perillyl Alcohol has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Perillyl Alcohol for actinic keratoses
Preliminary clinical research shows that applying perillyl alcohol 0.3% or 0.76% topically twice daily for 3 months does not improve actinic keratoses based on histopathological analysis.

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 Tirbanibulin on your own; if you are taking Perillyl Alcohol 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 Tirbanibulin

This page covers Perillyl Alcohol 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 Perillyl Alcohol

What is Perillyl Alcohol?

Cancer research (investigational)
Antioxidant interest
General wellness supplement
Aromatherapy-related products

Perillyl alcohol is a natural compound found in the essential oils of plants like mint, lavender, and citrus, and it has mainly been studied as an experimental anti-cancer agent rather than as an everyday supplement. The evidence in people is limited and still under investigation, so it should not be used to treat or prevent any disease without medical supervision. Talk to your pharmacist or doctor before trying it.

Naturally found in the essential oils of plants such as lavender, peppermint, sage, cherries, and citrus fruits; often produced from limonene · Capsules, oral liquid, and (in research settings) intranasal preparations

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

Perillyl Alcohol: dosing

There is no established standard supplement dose of perillyl alcohol for the general public. The doses used in research were chosen for clinical trials and were given under close medical supervision, so they do not apply to over-the-counter use.If you choose to use a product that contains perillyl alcohol, follow the directions on the product label and do not exceed them.

Taking Perillyl Alcohol and Tirbanibulin Together: Common Questions

Is it safe to take Perillyl Alcohol with Tirbanibulin?

We do not list a known interaction between Perillyl Alcohol and Tirbanibulin. 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 Perillyl Alcohol and Tirbanibulin have any of the same side effects?

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. 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 Perillyl Alcohol and Tirbanibulin 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 Perillyl Alcohol in each. That is a conversation for your prescriber, especially if Tirbanibulin is being adjusted to a target.

Does Tirbanibulin interact with any supplements?

Yes. Tirbanibulin has documented interactions with 3 supplements in our database — Perillyl Alcohol is not one of them. The Tirbanibulin interaction page linked on this page lists every one, ranked by severity.
