Drug & supplement interaction

Bulbine Natalensis + Paroxetine

Paroxetine brand names: Paxil CR, Paxil, Brisdelle.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Bulbine Natalensis and Paroxetine 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.

Bulbine Natalensis and Paroxetine

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 Paroxetine and Bulbine Natalensis 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.

How we checked

Why No Interaction Is Listed for Paroxetine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Paroxetine is filed under 12 classifications — including antidepressant drugs, cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors. Bulbine Natalensis has documented interactions with 7 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), cytochrome p450 1a2 (cyp1a2) substrates (moderate) and cytochrome p450 2c9 (cyp2c9) substrates (moderate) — and none of Paroxetine’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 Bulbine Natalensis and Paroxetine 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.

  • Diarrhea / Vomiting / Nausea Additional detail

    Bulbine Natalensis

    “Analysis of Bulbine natalensis root obtained from open street markets in South Africa shows that the plant root might contain high levels of aluminum (5559 mg/kg dry weight) and iron (4164 mg/kg dry weight). Theoretically, ingestion of plants containing this quantity of aluminum might impair cognitive function and lead to neurodegenerative diseases.”

Special populations

Bulbine Natalensis in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When used orally in large amounts. Animal research shows that Bulbine natalensis stem extract might be embryotoxic when administered at a dose of 100 mg/kg. Until more is known about its effects in humans, avoid using during pregnancy. There is insufficient reliable information about the safety of using topical Bulbine natalensis during pregnancy; avoid using.

From our pharmacist’s overview on the Paroxetine page

“I treat paroxetine (Paxil, Paxil CR, Brisdelle) as a medication where supplement choices genuinely matter, not one to wave through. This antidepressant raises serotonin, so about twenty of the ingredients listed here, lithium among them, can push serotonin too high and risk serotonin syndrome, a dangerous reaction.”

About Bulbine Natalensis

What is Bulbine Natalensis?

  • Boosting testosterone
  • Improving libido
  • Muscle building and athletic performance
  • General male vitality

Bulbine natalensis is a South African plant marketed mainly as a testosterone-boosting and libido supplement, but the human evidence is essentially absent and most claims come from animal studies. Animal research has also raised concerns about possible liver and kidney harm at higher doses, so caution is warranted. Talk to your pharmacist or doctor before trying it.

Taking Bulbine Natalensis and Paroxetine Together: Common Questions

Is it safe to take Bulbine Natalensis with Paroxetine?
We do not list a known interaction between Bulbine Natalensis and Paroxetine. 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 Bulbine Natalensis and Paroxetine have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Bulbine Natalensis and Paroxetine combination checked?
Interactions in our licensed database are recorded against drug classes. Paroxetine is filed under 12 classifications, and Bulbine Natalensis has documented interactions with 7 drug classes — none of Paroxetine'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 Bulbine Natalensis interact with any other medications?
Yes. Bulbine Natalensis has 919 documented drug interactions in our database — Paroxetine 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 Paroxetine interact with any supplements?
Yes. Paroxetine has documented interactions with 134 supplements in our database — Bulbine Natalensis is not one of them. The Paroxetine interaction page linked on this page lists every one, ranked by severity.
