Interaction report

Cudweed 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 Cudweed 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.

Cudweed overall Not established Limited modern safety data exist, so use with caution and talk to a healthcare provider first.
Pregnancy Avoid Not enough safety information is available, so avoid use during pregnancy.

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

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. Cudweed has documented interactions with 1 drug class — the most serious being antidiabetes drugs (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 to actually watch for

What Nintedanib Esylate’s Own FDA Label Lists

This is not an interaction — none of it involves Cudweed. 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 low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Raised blood pressure Worth acting on
  • Liver problems Worth acting on
  • Bleeding or bruising Worth acting on
  • A higher chance of infection Worth acting on
  • Weight loss mentioned in 9.7% of FDA reports for Nintedanib Esylate

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 31,339 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. Cudweed’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Cudweed side to compare — that is a limit of the record, not a statement that Cudweed has no side effects.

How to take them

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

At least one FDA label for a product containing Nintedanib Esylate says to take it with food. If you take Cudweed 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 Cudweed

What is Cudweed?

  • Mouth and throat irritation
  • Digestive upset
  • Mild high blood pressure (traditional)
  • Minor wounds and skin irritation
  • Coughs and respiratory complaints

Cudweed is a small, woolly-leaved plant used in traditional herbal medicine, mainly as a tea or gargle for sore throats, digestive upset, and minor skin problems. There is very little modern scientific evidence to confirm that it works for any condition, and safety data are limited, so it is best used cautiously and avoided in pregnancy and breastfeeding.

Gnaphalium uliginosum · Asteraceae · Aerial parts (flowering tops, leaves, and stems) · Tea (infusion), tincture, dried herb

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

Cudweed: dosing

There is no established or standardized dose for cudweed. It has not been studied enough to know a safe and effective amount, and traditional preparations vary.If you choose to use a commercial 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 treats certain scarring lung diseases in adults. All the supported products are indicated for idiopathic pulmonary fibrosis (IPF) and for chronic fibrosing interstitial lung diseases (ILDs) with a progressive phenotype (scarring lung disease that keeps getting worse).

Ofev, nintedanib capsules (100 mg and 150 mg) and one other nintedanib capsule product are also indicated to slow the decline in lung function in systemic sclerosis-associated interstitial lung disease (SSc-ILD). The nintedanib esylate capsule label lists only IPF and progressive chronic fibrosing ILDs.
