Drug & supplement interaction

Bupleurum + Dupilumab

Dupilumab brand name: Dupixent.

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 Bupleurum 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.

Bupleurum 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 Bupleurum 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.

Bupleurum safety at a glance

Bupleurum overall Use caution Generally used short-term in formulas, but it has been linked to rare lung and liver problems and quality varies.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety information, so it is best avoided while breastfeeding.

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

What to actually watch for

No Interaction Found — But Data Suggests Bupleurum and Dupilumab 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. One of them is worth acting on rather than waiting out — marked below.

    Bupleurum

    “Orally, combination products containing bupleurum have been reported to cause eosinophilic pneumonia, pulmonary edema, and multiple cases of pneumonitis. A specific combination product (sho-saiko-to), used in combination with interferon-alpha in patients with chronic active hepatitis, has also been associated with multiple cases of pneumonitis.”

    Dupilumab

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

Reported for Bupleurum but not commonly for Dupilumab: numbness or tingling, liver problems, reduced appetite and tiredness.

Effects for Dupilumab come from the ADVERSE REACTIONS section of its FDA label; effects for Bupleurum come from the Natural Medicines adverse-effect record, quoted above. 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 Bupleurum 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. Bupleurum 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 a wide range of inflammatory conditions driven by overactive immune signaling. It treats moderate-to-severe atopic dermatitis (eczema) in patients as young as 6 months old when topical prescription therapies haven't worked or aren't appropriate. It is also used as an add-on maintenance treatment for moderate-to-severe asthma (in patients 6 years and older with a certain immune profile or who depend on oral steroids), chronic rhinosinusitis with nasal polyps (in patients 12 and older), and COPD with an eosinophilic phenotype in adults. Additionally, Dupixent treats eosinophilic esophagitis (EoE, an inflammatory condition of the esophagus) in patients 1 year and older weighing at least 15 kg, prurigo nodularis (a skin condition with itchy nodules) in adults, chronic spontaneous urticaria (ongoing hives not caused by a known trigger) in patients 2 and older who still have symptoms on 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 used to relieve sudden asthma or COPD attacks, and it is not for other forms of urticaria.

Bupleurum has been studied for:

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

    Bupleurum for asthma

    Although there has been interest in using oral bupleurum for asthma, there is insufficient reliable information about the clinical effects of bupleurum 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 Bupleurum for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Bupleurum

What is Bupleurum?

Bupleurum
  • Liver and digestive support
  • Cold, flu, and fever
  • Inflammation
  • Stress and mood
  • Immune support

Bupleurum (Chai Hu) is a root used in traditional Chinese medicine, usually as part of multi-herb formulas, for liver, digestive, and fever-related complaints. High-quality human evidence for its benefits is limited, and it has been linked to lung and liver problems in some reports, so use it cautiously and only under professional guidance.

Bupleurum chinense · Apiaceae · Root · Capsules, tablets, dried root, teas, tinctures, and traditional Chinese herbal formulas

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

Bupleurum: dosing

There is no well-established standard dose of Bupleurum. Do not exceed the recommended amount, and avoid long-term use without professional guidance.

Taking Bupleurum and Dupilumab Together: Common Questions

Is it safe to take Bupleurum with Dupilumab?
We do not list a known interaction between Bupleurum 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 Bupleurum and Dupilumab 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.
Are Bupleurum 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 Bupleurum in each. That is a conversation for your prescriber, especially if Dupilumab is being adjusted to a target.
Does Bupleurum interact with any other medications?
Yes. Bupleurum has 327 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.
