Drug & supplement interaction

Daffodil + Tofacitinib

Tofacitinib brand names: Xeljanz, Xeljanz XR.

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 Tofacitinib 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 Tofacitinib

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 Tofacitinib 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 Tofacitinib, 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 Tofacitinib 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.

  • Headache reported in 7.3% of FDA reports for Tofacitinib Additional detail

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

    Tofacitinib

    Listed in the ADVERSE REACTIONS section of the FDA label for Tofacitinib. Read the label on DailyMed ›

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

Effects for Tofacitinib 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 185,980 voluntary FDA FAERS reports for Tofacitinib 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.

Overlapping uses

What Tofacitinib Is Prescribed For, and What Daffodil Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Tofacitinib is a prescription medicine with approved uses on its FDA label. Daffodil is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Daffodil has been studied for:

  • Joint pain studied, not established Daffodil has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Daffodil for joint pain

    Although there has been interest in using topical daffodil for joint pain, including sprains, there is insufficient reliable evidence about the clinical effects of daffodil for these conditions.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Tofacitinib on your own; if you are taking Daffodil for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Tofacitinib

This page covers Daffodil only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Tofacitinib page lists 184 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Active Hexose Correlated Compound (ahcc) (moderate).

By severity: 3 major · 143 moderate · 38 minor.

From our pharmacist’s overview on the Tofacitinib page

“Supplements deserve genuine care alongside tofacitinib (Xeljanz, Xeljanz XR), a medicine that deliberately dials down the immune system to control conditions like rheumatoid arthritis and ulcerative colitis. Most of the interactions on this page run through the liver enzymes that clear the drug, meaning an herb can push its blood level…”

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 Tofacitinib Together: Common Questions

Is it safe to take Daffodil with Tofacitinib?
We do not list a known interaction between Daffodil and Tofacitinib. 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 Tofacitinib have any of the same side effects?
Yes — our sources link each of them separately to 3 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.
Are Daffodil and Tofacitinib used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Daffodil in each. That is a conversation for your prescriber, especially if Tofacitinib is being adjusted to a target.
Does Tofacitinib interact with any supplements?
Yes. Tofacitinib has documented interactions with 184 supplements in our database — Daffodil is not one of them. The Tofacitinib interaction page linked on this page lists every one, ranked by severity.
