The bottom line No known interaction

We found no known interaction between Black Raspberry and Eplerenone 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.

Black Raspberry and Eplerenone

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 Eplerenone and Black Raspberry 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 Black Raspberry at all — not against Eplerenone, 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

What Eplerenone’s Own FDA Label Lists

This is not an interaction — none of it involves Black Raspberry. These are the most notable effects listed in the ADVERSE REACTIONS section of Eplerenone’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 8 of them are worth acting on rather than waiting out — marked below.

  • Heart failure Worth acting on mentioned in 7.6% of FDA reports for Eplerenone
  • High potassium Worth acting on
  • Low potassium Worth acting on
  • A heart attack Worth acting on
  • Kidney problems Worth acting on mentioned in 7.4% of FDA reports for Eplerenone
  • Chest pain Worth acting on
  • Raised blood pressure Worth acting on
  • Bleeding or bruising Worth acting on
  • Breast tenderness
  • Dizziness mentioned in 5.3% of FDA reports for Eplerenone

Showing the 10 most notable of 13 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Eplerenone. Read the label on DailyMed › Where a percentage is shown, it is the share of 12,732 voluntary FDA FAERS reports for Eplerenone that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Black Raspberry’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Black Raspberry side to compare — that is a limit of the record, not a statement that Black Raspberry has no side effects.

Overlapping uses

What Eplerenone Is Prescribed For, and What Black Raspberry Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Eplerenone is a prescription medicine with approved uses on its FDA label. Black Raspberry is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Eplerenone is prescribed for: Eplerenone treats two conditions. First, it is used to lower high blood pressure (hypertension) in adults. Lowering blood pressure reduces the risk of stroke and heart attack. It can be used alone or alongside other blood pressure medicines.

Read the rest of what Eplerenone is prescribed for

Second, eplerenone is used to improve survival in stable adults who have heart failure with reduced ejection fraction (HFrEF) — meaning the heart pumps less blood than normal — following an acute myocardial infarction (heart attack).

Black Raspberry has been studied for:

  • Hypertension studied, not established Black Raspberry has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Black Raspberry for hypertension

    Preliminary clinical research shows that taking black raspberry extract 1500 mg or 2500 mg orally daily for 8 weeks reduces 24-hour systolic blood pressure by 1-7 mmHg and nighttime systolic blood pressure by 2-5 mmHg compared to baseline in patients with prehypertension. Compared to the placebo group, these changes were significant.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Eplerenone on your own; if you are taking Black Raspberry for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Black Raspberry

What is Black Raspberry?

Black Raspberry
  • Antioxidant support
  • Heart health
  • Oral and gum health
  • Cancer prevention (under study)
  • Inflammation

Black raspberry is a nutrient-rich fruit packed with antioxidants like anthocyanins and ellagic acid, and as a food it is generally safe and healthy. Some early research explores it for cancer prevention, oral health, and heart health, but the evidence is preliminary and far from proven. Enjoy it as part of a balanced diet, and talk to your pharmacist or doctor before using concentrated supplements.

Rubus occidentalis · Rosaceae · Fruit (berries); sometimes leaves and seeds · Fresh or frozen berries, juice, powder, capsules, extracts, lozenges, gels

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

Black Raspberry: dosing

There is no official or standardized dose of black raspberry for any health condition. As a food, you can simply enjoy the fresh or frozen berries.For supplements, juices, and powders, the amount varies widely between products. The best approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Black Raspberry and Eplerenone Together: Common Questions

Are Black Raspberry and Eplerenone used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Black Raspberry in each. That is a conversation for your prescriber, especially if Eplerenone is being adjusted to a target.
Does Eplerenone interact with any supplements?
Yes. Eplerenone has documented interactions with 136 supplements in our database — Black Raspberry is not one of them. The Eplerenone interaction page linked on this page lists every one, ranked by severity.
