Bupropion brand names: Wellbutrin, Wellbutrin SR, Zyban, Wellbutrin XL, Aplenzin, and others.

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 Feverfew and Bupropion 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

Feverfew and Bupropion

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 Bupropion and Feverfew 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.

Feverfew safety at a glance

Feverfew overall Use caution Generally well tolerated short-term, but it can cause allergic reactions and mouth irritation in some people.
Pregnancy Possibly Unsafe When used orally. Feverfew might cause uterine contractions and abortion; avoid using. Read the full pregnancy detail
Breastfeeding Avoid Not enough reliable safety information, so it is best avoided while breastfeeding.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Bupropion

Interactions in our licensed database are recorded against drug classes, not just single drug names. Bupropion is filed under 6 classifications — including antidepressant drugs, cytochrome p450 2b6 (cyp2b6) substrates, cytochrome p450 2d6 (cyp2d6) inhibitors. Feverfew has documented interactions with 7 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), cytochrome p450 1a2 (cyp1a2) substrates (moderate) and cytochrome p450 2c19 (cyp2c19) substrates (moderate) — and none of Bupropion’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 Feverfew and Bupropion 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. One of them is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on Additional detail

    Feverfew

    “Orally, feverfew can cause skin rash. Topically, allergic contact dermatitis can occur. Allergic reactions to feverfew may be more likely in individuals sensitive to the Asteraceae/Compositae family. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.”

Reported for Feverfew but not commonly for Bupropion: changes to your period, mouth irritation or sores, a change in taste and bloating or gas.

Effects for Bupropion come from the ADVERSE REACTIONS section of its FDA label; effects for Feverfew come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 152,137 voluntary FDA FAERS reports for Bupropion 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 Bupropion

This page covers Feverfew only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Bupropion page lists 46 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), African Wild Potato (moderate), Artichoke (moderate) and Astaxanthin (moderate).

By severity: 1 major · 33 moderate · 12 minor.

From our pharmacist’s overview on the Bupropion page

“Bupropion (Wellbutrin, Zyban) deserves genuine care around supplements, and the entry to understand first is activated charcoal, the only major-rated interaction on this list. Charcoal and similar bulk products can soak up the drug in the gut and blunt its effect, so space them well apart from your dose.”

About Feverfew

What is Feverfew?

Feverfew
  • Migraine prevention
  • Headache
  • Fever (traditional)
  • Arthritis and joint pain
  • Menstrual discomfort

Feverfew is a daisy-family herb best known for migraine prevention, where some studies suggest it may modestly lower how often migraines occur, though the evidence is mixed. It is generally well tolerated for short-term use in most adults but should be avoided during pregnancy and breastfeeding and by people allergic to ragweed and related plants. Talk to your pharmacist or doctor before starting it.

Tanacetum parthenium · Asteraceae · Leaves (dried or fresh); sometimes whole above-ground parts · Capsules, tablets, dried leaf, liquid extracts, teas

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

Feverfew: dosing

There is no single official or proven dose for feverfew, and products vary widely in strength and how they are prepared. Many supplements are standardized to a certain amount of parthenolide, but the best dose is not firmly established.The safest approach is to follow the directions on the product label and not take more than recommended. If you have used feverfew for a while, do not stop it suddenly without checking first.

What Is Bupropion Used For?

Brand names: Wellbutrin, Wellbutrin SR, Zyban, Wellbutrin XL, Aplenzin, Forfivo XL

Bupropion is FDA-approved to treat major depressive disorder (MDD) — a form of clinical depression. Extended-release formulations (XL and hydrobromide versions, including Aplenzin) are also approved for the prevention of seasonal affective disorder (SAD), the pattern of depression that tends to arrive in autumn and winter.

Not all formulations share every indication. Aplenzin (bupropion hydrobromide extended-release) and bupropion hydrochloride extended-release tablets (XL) are indicated for both MDD and SAD. Bupropion hydrochloride extended-release tablets (SR) and bupropion hydrochloride immediate-release tablets are indicated for MDD only.

Most-Reported Side Effects for Bupropion

From FAERS, the FDA’s public side-effect reporting system (152,137 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 11,909 reports

Taking Feverfew and Bupropion Together: Common Questions

Is it safe to take Feverfew with Bupropion?
We do not list a known interaction between Feverfew and Bupropion. 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 Feverfew and Bupropion have any of the same side effects?
Yes — our sources link each of them separately to 10 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.
How was the Feverfew and Bupropion combination checked?
Interactions in our licensed database are recorded against drug classes. Bupropion is filed under 6 classifications, and Feverfew has documented interactions with 7 drug classes — none of Bupropion'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 Feverfew interact with any other medications?
Yes. Feverfew has 929 documented drug interactions in our database — Bupropion 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 Bupropion interact with any supplements?
Yes. Bupropion has documented interactions with 46 supplements in our database — Feverfew is not one of them. The Bupropion interaction page linked on this page lists every one, ranked by severity.
