Drug & supplement interaction

Daffodil + Flurandrenolide

Flurandrenolide brand name: Cordran.

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 Daffodil and Flurandrenolide 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.

Daffodil and Flurandrenolide

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 Flurandrenolide 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 Flurandrenolide, 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 Flurandrenolide 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 5.5% of FDA reports for Flurandrenolide Additional detail

    Daffodil

    “Topically, skin contact with any part of the daffodil plant can cause dermatitis, sometimes referred to as "daffodil itch" or "lily rash" (18,5004,5005).

    Orally, large doses of daffodil can cause toxicity, including excessive sweating.”

    Flurandrenolide

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

Reported for Daffodil but not commonly for Flurandrenolide: sweating, stomach pain, blurred vision and seizures.

Effects for Flurandrenolide 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 329 voluntary FDA FAERS reports for Flurandrenolide 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

See Every Supplement That Interacts With Flurandrenolide

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

“DMSO is the risk to know about first. Applied to the same skin as flurandrenolide (Cordran), a prescription steroid cream for inflamed, itchy conditions like eczema and psoriasis, DMSO may pull more of the drug through the skin, amplifying its effects and its side effects alike.”

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.

Taking Daffodil and Flurandrenolide Together: Common Questions

Is it safe to take Daffodil with Flurandrenolide?
We do not list a known interaction between Daffodil and Flurandrenolide. 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 Flurandrenolide 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. 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.
Does Flurandrenolide interact with any supplements?
Yes. Flurandrenolide has documented interactions with 3 supplements in our database — Daffodil is not one of them. The Flurandrenolide interaction page linked on this page lists every one, ranked by severity.
