Drug & supplement interaction

Daffodil + Nintedanib Esylate

Nintedanib Esylate brand name: Ofev.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Daffodil and Nintedanib Esylate 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 label for Nintedanib Esylate states a food rule worth keeping to, and 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

Daffodil 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 Daffodil 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 Daffodil at all — not against Nintedanib Esylate, 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

No Interaction Found — But Data Suggests Daffodil and Nintedanib Esylate May Share Several of the Same Side Effects

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.

  • Diarrhea / Stomach pain / Vomiting reported in 32.4% of FDA reports for Nintedanib Esylate Additional detail

    Daffodil

    “Daffodil is generally regarded as unsafe for use. Any benefits of therapy may not outweigh the risk of toxicity.

    Serious Adverse Effects (Rare):

    Orally: Irritation and swelling of the mouth, tongue, and throat, and sudden onset of vomiting, diarrhea, and abdominal pain. Large doses have also been reported to cause blurred vision, coma, convulsions, dizziness, headache, hypotension, salivation, sweating, and tremors.”

    Daffodil · Natural Medicines adverse-effect record, reported in cluster headache.

    “Orally, daffodil can cause irritation and swelling of the mouth, tongue, and throat, as well as sudden onset of vomiting, diarrhea, and abdominal pain. Vomiting and diarrhea often limit the progression of symptoms, and adults typically recover within 3-4 hours. Large doses of daffodil can cause toxicity, including excessive salivation (18,19,101223).”

Reported for Daffodil but not commonly for Nintedanib Esylate: sweating, blurred vision, seizures and low blood pressure.

Effects for Nintedanib Esylate come from the ADVERSE REACTIONS section of its FDA label; effects for Daffodil come from the Natural Medicines adverse-effect record, quoted above. 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. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

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

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

See Every Supplement That Interacts With Nintedanib Esylate

This page covers Daffodil only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nintedanib Esylate page lists 285 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Danshen (major), Grapefruit (major), Piracetam (major) and St. John's Wort (major).

By severity: 5 major · 240 moderate · 40 minor.

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 Daffodil

What is Daffodil?

  • Traditional anti-inflammatory remedy
  • Folk use for tumors and skin growths
  • Source of galantamine for memory/Alzheimer's
  • Antimicrobial folk use
  • Topical traditional remedies

Daffodil is a beautiful but toxic plant that contains alkaloids, including the one used to make the Alzheimer's drug galantamine. It is not safe to take as a homemade supplement, and all parts of the plant—especially the bulb—can cause serious poisoning if eaten. Leave any medicinal use to standardized, regulated medications prescribed by a doctor.

Narcissus pseudonarcissus · Amaryllidaceae · Bulb, flower, and leaves (source of certain alkaloids) · Not commonly available as a consumer supplement; the plant is the source of the prescription drug galantamine

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

Daffodil: dosing

There is no safe established dose of daffodil as a supplement, and it should not be taken by mouth. Because the whole plant is toxic, no amount can be recommended for self-treatment.The only proven medical use linked to this plant is the prescription drug galantamine, which is manufactured to a precise, standardized dose and must be prescribed and monitored by a healthcare provider.

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.

Taking Daffodil and Nintedanib Esylate Together: Common Questions

Is it safe to take Daffodil with Nintedanib Esylate?
We do not list a known interaction between Daffodil and Nintedanib Esylate. 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 Daffodil and Nintedanib Esylate have any of the same side effects?
Yes — our sources link each of them separately to 6 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.
Should I take Daffodil and Nintedanib Esylate at the same time of day?
At least one FDA label for a product containing Nintedanib Esylate says to take it with food. If you take Daffodil on an empty stomach out of habit, keep them separate and take Nintedanib Esylate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Nintedanib Esylate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Nintedanib Esylate interact with any supplements?
Yes. Nintedanib Esylate has documented interactions with 285 supplements in our database — Daffodil is not one of them. The Nintedanib Esylate interaction page linked on this page lists every one, ranked by severity.
