The bottom line No known interaction

We found no known interaction between Spanish Broom 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.

Spanish Broom 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 Spanish Broom 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 Spanish Broom at all — not against Bupropion, 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 Spanish Broom 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.

  • Confusion Worth acting on Additional detail

    “Ingestion of Spanish broom flowers or seeds collected directly from the plant has been associated with cases of sedation, confusion, dizziness, headache, agitation, and tremors.

Everything else you take

See Every Supplement That Interacts With Bupropion

This page covers Spanish Broom 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 Spanish Broom

What is Spanish Broom?

  • Diuretic ('water pill') effect
  • Heart and circulation complaints (folk use)
  • Mild laxative
  • Fragrance in perfumes and cosmetics
  • Traditional fiber and dye source

Spanish Broom is a Mediterranean flowering shrub used historically as a diuretic and heart remedy and today mostly as a perfume ingredient. It contains toxic alkaloids that can affect the heart and nervous system, and there is no reliable modern evidence that it is safe or effective for any health condition. Because of the poisoning risk, it is best avoided as an oral supplement.

Spartium junceum · Fabaceae · Flowers, and sometimes the flowering tops and seeds · Traditional teas or infusions, tinctures, and an essential oil (absolute) used in perfumery; rarely sold as a standardized supplement

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

Spanish Broom: dosing

There is no established safe dose for Spanish Broom as a supplement, and it is not recommended for internal use. Because the plant is toxic and its alkaloid content varies, no reliable, safe amount can be given.We do not provide a dose for this plant.

Taking Spanish Broom and Bupropion Together: Common Questions

Is it safe to take Spanish Broom with Bupropion?
We do not list a known interaction between Spanish Broom 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 Spanish Broom and Bupropion have any of the same side effects?
Yes — our sources link each of them separately to 8 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.
Does Bupropion interact with any supplements?
Yes. Bupropion has documented interactions with 46 supplements in our database — Spanish Broom is not one of them. The Bupropion interaction page linked on this page lists every one, ranked by severity.
