Drug & supplement interaction

Butterbur + Bisoprolol

Bisoprolol brand name: Zebeta.

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 Butterbur and Bisoprolol 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.

Butterbur and Bisoprolol

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 Bisoprolol and Butterbur 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 Bisoprolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Bisoprolol is filed under 5 classifications — including beta-blockers, antihypertensive drugs, cytochrome p450 2d6 (cyp2d6) substrates. Butterbur has documented interactions with 1 drug class — the most serious being cytochrome p450 3a4 (cyp3a4) inducers (moderate) — and none of Bisoprolol’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 Butterbur and Bisoprolol 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.

See Every Supplement That Interacts With Bisoprolol

This page covers Butterbur only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Bisoprolol page lists 183 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Indian Snakeroot (major) and Tyramine (major).

By severity: 5 major · 151 moderate · 27 minor.

From our pharmacist’s overview on the Bisoprolol page

“Bisoprolol (Zebeta) slows your heart and lowers your blood pressure, so treat these 183 supplement interactions as a genuine concern rather than fine print, and learn the five rated major first. Most of the list, 119 ingredients in all, either adds to bisoprolol's pressure-lowering effect or works against it, so your numbers can drift…”

About Butterbur

What is Butterbur?

  • Migraine prevention
  • Hay fever (allergic rhinitis)
  • Asthma symptoms
  • Stomach and digestive upset
  • Tension headaches

Butterbur is a plant extract most studied for preventing migraines and easing hay fever symptoms, and some standardized products show promise. However, raw or unprocessed butterbur contains compounds that can seriously harm the liver, so only use PA-free (pyrrolizidine alkaloid-free) products, and avoid it during pregnancy and breastfeeding. Talk to your pharmacist or doctor before trying it.

Petasites hybridus · Asteraceae · Roots (rhizome) and leaves · Capsules, tablets, standardized extracts, tinctures

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

Butterbur: dosing

There is no single official dose for butterbur, and the right amount depends on the specific product and how it is standardized. Studies have used standardized extracts, but you should not try to copy study doses on your own.The safest approach is to follow the directions on the product label and choose only products that are clearly labeled PA-free.

About Bisoprolol

What Is Bisoprolol Used For?

Brand name: Zebeta

Bisoprolol fumarate tablets are used to manage high blood pressure (hypertension). Lowering blood pressure reduces the strain on the heart and blood vessels, helping prevent serious complications over time.

It can be used on its own or combined with other blood pressure-lowering medicines, such as thiazide diuretics. All supported products — including those labeled as Bisoprolol and Bisoprolol Fumarate — share this indication.

Taking Butterbur and Bisoprolol Together: Common Questions

Is it safe to take Butterbur with Bisoprolol?
We do not list a known interaction between Butterbur and Bisoprolol. 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 Butterbur and Bisoprolol have any of the same side effects?
Yes — our sources link each of them separately to 9 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 Butterbur and Bisoprolol combination checked?
Interactions in our licensed database are recorded against drug classes. Bisoprolol is filed under 5 classifications, and Butterbur has documented interactions with 1 drug class — none of Bisoprolol'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 Butterbur interact with any other medications?
Yes. Butterbur has 87 documented drug interactions in our database — Bisoprolol 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 Bisoprolol interact with any supplements?
Yes. Bisoprolol has documented interactions with 183 supplements in our database — Butterbur is not one of them. The Bisoprolol interaction page linked on this page lists every one, ranked by severity.
