Drug & supplement interaction

Capers + Tavaborole

Tavaborole brand name: Kerydin.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Capers and Tavaborole 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.

Capers and Tavaborole

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 Tavaborole and Capers 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.

Capers safety at a glance

Capers overall Use caution Generally safe as a food, but concentrated supplements are not well studied.
Pregnancy Use caution Food amounts are likely fine, but avoid medicinal or concentrated doses due to lack of safety data.
Breastfeeding Use caution Food amounts are likely fine, but concentrated supplements lack safety data, so caution is advised.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Tavaborole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Tavaborole is filed under a single classification — topical drugs. Capers has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Tavaborole’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 to actually watch for

No Interaction Found — But Data Suggests Capers and Tavaborole 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.

  • A skin rash reported in 9.1% of FDA reports for Tavaborole Additional detail

    Capers

    “Orally, capers seem to be well tolerated. No adverse effects have been reported in clinical research; however, a high-quality assessment of safety has not been conducted. Topically, capers can cause contact dermatitis.”

    Listed in the ADVERSE REACTIONS section of the FDA label for Tavaborole, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Effects for Tavaborole come from the ADVERSE REACTIONS section of its FDA label; effects for Capers come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 55 voluntary FDA FAERS reports for Tavaborole that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Everything else you take

This page covers Capers only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Tavaborole 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 Tavaborole page

“Tavaborole (Kerydin) is a solution you paint onto the toenail for fungal infections, and its supplement concerns stay right where you apply it. Only three ingredients have interactions on file, two rated moderate and one minor, and every one involves putting something else on the skin.”

About Capers

What is Capers?

  • Digestive support
  • Antioxidant source
  • Blood sugar support
  • Anti-inflammatory
  • Skin and traditional tonic uses

Capers are the edible pickled flower buds of the Capparis spinosa shrub, used widely as food and in traditional medicine. They contain antioxidant plant compounds, but high-quality human studies on health benefits are limited, so the supplement claims remain largely unproven. As a food, capers are generally safe, but talk to your pharmacist or doctor before using concentrated extracts.

Capparis spinosa · Capparaceae · Flower buds, fruit, root bark, and leaves · Pickled or brined buds (food), capsules, extracts, dried powder

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

Capers: dosing

There is no established standard dose for capers as a supplement. As a food, people simply use them as a flavoring in small amounts.For capsules or extracts, follow the directions on the product label, since strengths vary widely between brands.

Do Capers and Tavaborole 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.

How was the Capers and Tavaborole combination checked?
Interactions in our licensed database are recorded against drug classes. Tavaborole is filed under 1 classification, and Capers has documented interactions with 1 drug class — none of Tavaborole'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.
