Pao Pereira 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 Pao Pereira 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 Pao Pereira at all — not against Tavaborole, 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 Tavaborole’s Own FDA Label Lists

This is not an interaction — none of it involves Pao Pereira. These are the most notable effects listed in the ADVERSE REACTIONS section of Tavaborole’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. One of them is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on
  • A skin rash mentioned in 9.1% of FDA reports for Tavaborole

From the ADVERSE REACTIONS section of the FDA label for Tavaborole. Read the label on DailyMed › 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. Pao Pereira’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Pao Pereira side to compare — that is a limit of the record, not a statement that Pao Pereira has no side effects.

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.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Pao Pereira is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Pao Pereira reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Pao Pereira and Tavaborole records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Pao Pereira

What is Pao Pereira?

  • Immune support
  • Cancer support (complementary use)
  • Antimalarial/fever (traditional)
  • Digestive complaints (traditional)
  • General tonic

Pao Pereira is a bark extract from a South American tree that is marketed mainly as a complementary cancer and immune-support supplement. Human evidence is very limited, and most research comes from laboratory and animal studies, so it should not be used in place of proven medical care. Talk with your pharmacist or doctor before trying it, especially if you have a serious health condition.

Geissospermum laeve · Apocynaceae · Bark (and bark extract) · Capsules, tinctures, liquid extracts, powdered bark
