Drug & supplement interaction

Butcher's Broom + Finerenone

Finerenone brand name: Kerendia.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Butcher's Broom and Finerenone 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.

Butcher's Broom and Finerenone

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 Finerenone and Butcher's 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.

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.

Butcher's Broom safety at a glance

Butcher's Broom overall Use caution Generally well tolerated short-term in most healthy adults, but evidence on long-term safety is limited.
Pregnancy Avoid Safety has not been established, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough safety information exists, so avoid use 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 Finerenone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Finerenone is filed under 3 classifications — potassium-sparing diuretics, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Butcher's Broom has documented interactions with 2 drug classes — the most serious being alpha-adrenergic agonists (moderate) and alpha-adrenergic antagonists (moderate) — and none of Finerenone’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.

No Interaction Found — But Data Suggests Butcher's Broom and Finerenone May Share a Side Effect

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.

  • High potassium Worth acting on reported in 14.9% of FDA reports for Finerenone Additional detail

    “Orally, butcher's broom may cause nausea, vomiting, diarrhea, dyspepsia, heartburn, and gastritis.

    Finerenone

    Listed in the ADVERSE REACTIONS section of the FDA label for Finerenone, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Butcher's Broom but not commonly for Finerenone: a fast or pounding heartbeat, dehydration, a skin rash and stomach upset.

Effects for Finerenone come from the ADVERSE REACTIONS section of its FDA label; effects for Butcher's Broom come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 2,960 voluntary FDA FAERS reports for Finerenone 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.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

From our pharmacist’s overview on the Finerenone page

“Kerendia (finerenone) protects the kidneys and heart in people with type 2 diabetes and chronic kidney disease, and because the body clears it through one main enzyme, CYP3A4, its supplement list calls for genuine care. Of the 146 ingredients on file, 121 can push that enzyme up or down, letting finerenone drift too high or too low.”

About Butcher's Broom

What is Butcher's Broom?

Butcher's Broom
  • Chronic venous insufficiency
  • Varicose veins
  • Leg swelling and heaviness
  • Hemorrhoids
  • Circulation problems

Butcher's broom is a plant extract most often used for circulation problems in the legs, such as chronic venous insufficiency, where some evidence suggests it may help reduce swelling and discomfort. Quality and dosing vary widely between products, and it should not replace proven treatments. Talk with your pharmacist or doctor before starting it, especially if you are pregnant, breastfeeding, or have a health condition.

Ruscus aculeatus · Asparagaceae · Rhizome (underground stem) and roots · Capsules, tablets, extracts, teas, and topical creams or ointments

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

Butcher's Broom: dosing

There is no single official or standardized dose of butcher's broom. Products vary widely in their strength, how they are made, and whether they include other ingredients, which makes it hard to compare them.Many extracts are standardized to a certain amount of ruscogenins, but the right amount depends on the specific product.

About Finerenone

What Is Finerenone Used For?

Brand name: Kerendia

Kerendia (finerenone) is used in adults with chronic kidney disease (CKD) linked to type 2 diabetes. It helps reduce the risk of kidney function decline, end-stage kidney disease, cardiovascular death, non-fatal heart attack, and hospitalization for heart failure in these patients.

Kerendia is also used in adults with heart failure who have a left ventricular ejection fraction (LVEF) — a measure of how well the heart pumps — of 40% or higher. In this group, it reduces the risk of cardiovascular death, hospitalization for heart failure, and urgent heart failure visits.

Most-Reported Side Effects for Finerenone

From FAERS, the FDA’s public side-effect reporting system (2,960 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Butcher's Broom and Finerenone Together: Common Questions

Is it safe to take Butcher's Broom with Finerenone?
We do not list a known interaction between Butcher's Broom and Finerenone. 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 Butcher's Broom and Finerenone have any of the same side effects?
Yes — our sources link each of them separately to one 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 Butcher's Broom and Finerenone combination checked?
Interactions in our licensed database are recorded against drug classes. Finerenone is filed under 3 classifications, and Butcher's Broom has documented interactions with 2 drug classes — none of Finerenone'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 Butcher's Broom interact with any other medications?
Yes. Butcher's Broom has 158 documented drug interactions in our database — Finerenone 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 Finerenone interact with any supplements?
Yes. Finerenone has documented interactions with 146 supplements in our database — Butcher's Broom is not one of them. The Finerenone interaction page linked on this page lists every one, ranked by severity.
