Interaction report

Black Horehound and Nintedanib Esylate

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 Nintedanib Esylate and Black Horehound 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.

How we checked

Why No Interaction Is Listed for Nintedanib Esylate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nintedanib Esylate is filed under 5 classifications — including anticoagulant/antiplatelet drugs, p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates. Black Horehound has documented interactions with 1 drug class — the most serious being dopamine agonists (moderate) — and none of Nintedanib Esylate’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 Nintedanib Esylate’s Own FDA Label Lists

This is not an interaction — none of it involves Black Horehound. These are the most notable effects listed in the ADVERSE REACTIONS section of Nintedanib Esylate’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. 9 of them are worth acting on rather than waiting out — marked below.

  • A change in thyroid levels Worth acting on
  • A heart attack Worth acting on
  • Pancreatitis Worth acting on
  • A higher chance of infection Worth acting on mentioned in 10.6% of FDA reports for Nintedanib Esylate
  • A low platelet count Worth acting on

Showing the 10 most notable of 24 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Nintedanib Esylate. Read the label on DailyMed › Where a percentage is shown, it is the share of 188 voluntary FDA FAERS reports for Nintedanib Esylate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Black Horehound’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Black Horehound side to compare — that is a limit of the record, not a statement that Black Horehound has no side effects.

How to take them

Some Nintedanib Esylate Products Have a Food Rule — Black Horehound Should Not Break It

At least one FDA label for a product containing Nintedanib Esylate says to take it with food. If you take Black Horehound on an empty stomach out of habit, keep them separate — and take Nintedanib Esylate with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Nintedanib Esylate products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

2 DOSAGE AND ADMINISTRATION Recommended dosage: 150 mg taken orally twice daily approximately 12 hours apart taken with food.

From the Dosage and Administration section of the FDA label we read for Nintedanib Esylate — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Nintedanib Esylate page

“You take Ofev (nintedanib) to slow lung scarring, and this page deserves a careful read before any supplement joins it. Of the 285 ingredients here, the biggest cluster, over 200, can add to bleeding risk, a real concern since nintedanib itself can make you bleed more easily.”

About Black Horehound

What is Black Horehound?

Black Horehound
  • Nausea and vomiting
  • Anxiety and nervous tension
  • Sleep problems
  • Mild digestive upset
  • Coughs and respiratory complaints

Black horehound is a traditional European herb mainly used for nausea, mild anxiety, and digestive upset, but high-quality human studies are lacking, so its effectiveness is largely unproven. It has a strong, unpleasant smell and taste, and its safety has not been well studied, so it should be avoided in pregnancy and breastfeeding and used cautiously by everyone else.

Ballota nigra · Lamiaceae · Above-ground parts (flowering tops and leaves) · Tea (infusion), liquid extract, tincture, capsules

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

Black Horehound: dosing

There is no well-established, standardized dose for black horehound. Traditional use has involved teas made from the dried herb and liquid extracts or tinctures, but reliable dosing from quality human studies is not available.If you choose to use a product, follow the directions on the label and do not exceed the recommended amount.

About Nintedanib

What Is Nintedanib Used For?

Brand name: Ofev

Nintedanib capsules are approved for adults with idiopathic pulmonary fibrosis (IPF) — a chronic, progressive scarring of the lungs — and for adults with chronic fibrosing interstitial lung diseases (ILDs) with a progressive phenotype, meaning fibrosing lung diseases that continue to worsen over time despite treatment.

Nintedanib capsules (including Ofev) are also indicated to slow the rate of decline in lung function in adults with systemic sclerosis-associated interstitial lung disease (SSc-ILD), a lung complication of the autoimmune condition systemic sclerosis (scleroderma). Note that the Nintedanib esylate capsule product is approved for IPF and chronic fibrosing ILDs with a progressive phenotype, but SSc-ILD approval is carried by Ofev and other nintedanib capsule products — always confirm with your prescriber which product you have been prescribed.
