Drug & supplement interaction

Bupleurum + Fluoxetine

Fluoxetine brand names: Prozac, Sarafem.

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 Bupleurum and Fluoxetine 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

Bupleurum and Fluoxetine

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 Fluoxetine 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.

How we checked

Why No Interaction Is Listed for Fluoxetine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fluoxetine is filed under 14 classifications — including antidepressant drugs, cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors. Bupleurum has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and immunosuppressants (moderate) — and none of Fluoxetine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Bupleurum and Fluoxetine 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. 2 of them are worth acting on rather than waiting out — marked below.

Overlapping uses

What Fluoxetine 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. Fluoxetine 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.

Fluoxetine is prescribed for: Fluoxetine is approved to treat four conditions: major depressive disorder (MDD), obsessive-compulsive disorder (OCD), bulimia nervosa (a binge-eating and purging disorder), and panic disorder — with or without agoraphobia (fear of situations that feel hard to escape). It works for adults across all four conditions, and for children and teens with depression (ages 8–18) and OCD (ages 7–17).

Bupleurum has been studied for:

  • Depression 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 depression

    Oral bupleurum has only been evaluated in combination with other ingredients; its effect when used alone is unclear.

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 Fluoxetine 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.

By severity: 8 major · 127 moderate · 28 minor.

From our pharmacist’s overview on the Fluoxetine page

“Grapefruit is the surprise at the top of fluoxetine's (Prozac) supplement list. In large amounts it can stretch the QT interval, the electrical pause between heartbeats, and fluoxetine, a widely prescribed antidepressant, can do the same, raising the odds of a dangerous rhythm.”

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 Fluoxetine Together: Common Questions

Is it safe to take Bupleurum with Fluoxetine?
We do not list a known interaction between Bupleurum and Fluoxetine. 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 Fluoxetine 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.
Are Bupleurum and Fluoxetine 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 Fluoxetine is being adjusted to a target.
How was the Bupleurum and Fluoxetine combination checked?
Interactions in our licensed database are recorded against drug classes. Fluoxetine is filed under 14 classifications, and Bupleurum has documented interactions with 3 drug classes — none of Fluoxetine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Bupleurum interact with any other medications?
Yes. Bupleurum has 327 documented drug interactions in our database — Fluoxetine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Fluoxetine interact with any supplements?
Yes. Fluoxetine has documented interactions with 163 supplements in our database — Bupleurum is not one of them. The Fluoxetine interaction page linked on this page lists every one, ranked by severity.
