Drug & supplement interaction

Clay + Tirbanibulin

Tirbanibulin brand name: Klisyri.

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 Clay 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

Clay 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 Clay 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.

Clay safety at a glance

Clay overall Use caution Topical use is generally low-risk, but oral clay can be contaminated with heavy metals.
Pregnancy Possibly Unsafe When used orally, long-term. Clay ingestion during pregnancy appears to be associated with an increased incidence of pre-eclampsia, hypertension, and/or edema.... Read the full pregnancy detail
Breastfeeding Avoid Not enough safety data; avoid taking clay by mouth while breastfeeding.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Tirbanibulin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Tirbanibulin is filed under a single classification — topical drugs. Clay has documented interactions with 2 drug classes — the most serious being cimetidine (tagamet) (moderate) and quinine (moderate) — and none of Tirbanibulin’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.

No Interaction Found — But Data Suggests Clay 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.

Clay in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When used orally, long-term. Clay ingestion during pregnancy appears to be associated with an increased incidence of pre-eclampsia, hypertension, and/or edema. There is insufficient reliable information available about the safety of ingesting clay short-term during pregnancy.

This page covers Clay 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 Clay

What is Clay?

  • Detox and digestive complaints
  • Skin care (masks, acne, irritation)
  • Diarrhea and upset stomach
  • Drawing out toxins or impurities
  • Wound and rash poultices

Clay is a fine, mineral-rich earth (such as bentonite or kaolin) used on the skin and sometimes taken by mouth for digestive and 'detox' purposes. Topical use for masks and minor skin issues is popular and generally low-risk, but swallowing clay carries real safety concerns, including possible contamination with lead and other heavy metals. Talk to a pharmacist or doctor before taking clay internally.

Mineral-rich clay (bentonite, kaolin, French green clay, and similar) · Powder, capsules, masks, poultices, suspensions/drinks

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

Clay: dosing

There is no well-established, standardized dose for clay, and no recommended safe amount for eating it. Because of contamination and absorption concerns, taking clay internally is generally not recommended without medical guidance.If you use a topical product, follow the label directions for how long to leave a mask on and how often to use it. Choose products that are independently tested for heavy metals.

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.

Taking Clay and Tirbanibulin Together: Common Questions

Is it safe to take Clay with Tirbanibulin?
We do not list a known interaction between Clay 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 Clay 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.
How was the Clay and Tirbanibulin combination checked?
Interactions in our licensed database are recorded against drug classes. Tirbanibulin is filed under 1 classification, and Clay has documented interactions with 2 drug classes — none of Tirbanibulin's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Clay interact with any other medications?
Yes. Clay has 3 documented drug interactions in our database — Tirbanibulin is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Tirbanibulin interact with any supplements?
Yes. Tirbanibulin has documented interactions with 3 supplements in our database — Clay is not one of them. The Tirbanibulin interaction page linked on this page lists every one, ranked by severity.
