Drug & supplement interaction

Elderberry + Dupilumab

Dupilumab brand name: Dupixent.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Elderberry and Dupilumab 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.

Interaction report

Elderberry and Dupilumab

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 Dupilumab and Elderberry 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.

What to actually watch for

No Interaction Found — But Data Suggests Elderberry and Dupilumab 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.

  • Dizziness Additional detail

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

Reported for Elderberry but not commonly for Dupilumab: stomach pain, liver problems, vomiting and numbness or tingling.

Effects for Dupilumab come from the ADVERSE REACTIONS section of its FDA label; effects for Elderberry come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 478,975 voluntary FDA FAERS reports for Dupilumab 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 Dupilumab Is Prescribed For, and What Elderberry Has Been Studied For

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

Dupilumab is prescribed for: Dupixent (dupilumab) injection is approved for several inflammatory conditions. It treats moderate-to-severe atopic dermatitis (eczema) in patients 6 months and older when topical treatments haven't worked well enough. It is also used as an add-on maintenance treatment for moderate-to-severe asthma (ages 6 and up), chronic rhinosinusitis with nasal polyps (ages 12 and up), and COPD with an eosinophilic phenotype in adults. Additionally, Dupixent treats eosinophilic esophagitis (EoE, a chronic inflammatory condition of the esophagus) in patients 1 year and older weighing at least 15 kg, prurigo nodularis (severe itchy skin nodules) in adults, chronic spontaneous urticaria (hives without a clear trigger) in patients 2 and older who haven't responded to antihistamines, bullous pemphigoid (a blistering skin disease) in adults, and allergic fungal rhinosinusitis in patients 6 and older with a history of sinus surgery.

It is not for relief of sudden or acute breathing attacks.

Elderberry has been studied for:

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

    Elderberry for rhinosinusitis

    Although there has been interest in using oral elderberry for rhinosinusitis, there is insufficient reliable information about the clinical effects of elderberry for this purpose.

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 Dupilumab on your own; if you are taking Elderberry for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Elderberry

What is Elderberry?

Elderberry
  • Colds
  • Flu (influenza)
  • Other respiratory infections
  • Immune support
  • Sinus and upper respiratory symptoms

Elderberry is a popular herbal supplement, mainly taken to help with colds and flu. Some small studies suggest it may modestly shorten cold or flu symptoms, but the evidence is limited and not conclusive. Cooked berries and properly prepared products are generally well tolerated, but raw or unripe parts can cause nausea and should be avoided.

Sambucus nigra · Adoxaceae · Berries and flowers (ripe, cooked fruit and dried flowers) · Syrup, gummies, lozenges, capsules, tablets, teas, and liquid extracts

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

Elderberry: dosing

There is no official standardized dose for elderberry. Products vary widely in strength and form, from syrups and gummies to capsules and teas, so the amount of active ingredient differs from one product to another.The best approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Elderberry and Dupilumab Together: Common Questions

Is it safe to take Elderberry with Dupilumab?
We do not list a known interaction between Elderberry and Dupilumab. 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 Elderberry and Dupilumab have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Elderberry and Dupilumab 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 Elderberry in each. That is a conversation for your prescriber, especially if Dupilumab is being adjusted to a target.
Does Elderberry interact with any other medications?
Yes. Elderberry has 121 documented drug interactions in our database — Dupilumab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
