Drug & supplement interaction

Lavender + Finerenone

Finerenone brand name: Kerendia.

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 Lavender 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.

Lavender 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 Lavender 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.

Lavender safety at a glance

Lavender overall Use caution Generally well tolerated in approved forms, but essential oil is toxic if swallowed and skin contact can irritate some people.
Pregnancy Use caution Not enough reliable safety data, so avoid medicinal amounts unless your doctor approves.
Breastfeeding Use caution Safety is not well studied, so use only with guidance from your healthcare provider.

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. Lavender has documented interactions with 1 drug class — the most serious being cns depressants (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 Lavender 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.

  • Kidney problems Worth acting on reported in 22.8% of FDA reports for Finerenone Additional detail

    Lavender

    “In one case report, a 24-year-old male presented with shortness of breath, weakness, nausea, and decreased urine output following the intake of Spanish lavender tea twice daily for 5 days. After presenting to the hospital, the patient was diagnosed with acute kidney failure secondary to acute interstitial nephritis likely due to lavender consumption.”

    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 Lavender but not commonly for Finerenone: stomach upset, shortness of breath, increased appetite and constipation.

Effects for Finerenone come from the ADVERSE REACTIONS section of its FDA label; effects for Lavender 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.

See Every Supplement That Interacts With Finerenone

This page covers Lavender only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Finerenone page lists 146 supplements it has a documented interaction with, worst first, each one explained.

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

By severity: 3 major · 101 moderate · 42 minor.

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 Lavender

What is Lavender?

Lavender
  • Anxiety and stress
  • Sleep problems
  • Relaxation and calming
  • Minor skin conditions
  • Aromatherapy

Lavender is a fragrant herb most popular for promoting relaxation, easing anxiety, and supporting sleep, with some encouraging evidence for a standardized oral lavender oil product for anxiety. While generally well tolerated, the essential oil should never be swallowed unless made for that purpose, and pregnant or breastfeeding people should use caution and talk to a healthcare provider first.

Lavandula angustifolia · Lamiaceae · Flowers and essential oil · Essential oil, oral capsules, tea, dried flowers, aromatherapy products, topical creams

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

Lavender: dosing

There is no single standardized dose of lavender that fits all products or all uses. The right amount depends on the form, whether it is a tea, capsule, oil, or aromatherapy product.The best approach is to follow the directions on the product label and not exceed the recommended amount. Essential oil intended for aromatherapy or diluted skin use should not be swallowed.

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.

Glomerular filtration rate decreased 308 reports

Taking Lavender and Finerenone Together: Common Questions

Is it safe to take Lavender with Finerenone?
We do not list a known interaction between Lavender 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 Lavender 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 Lavender and Finerenone combination checked?
Interactions in our licensed database are recorded against drug classes. Finerenone is filed under 3 classifications, and Lavender has documented interactions with 1 drug class — 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 Lavender interact with any other medications?
Yes. Lavender has 248 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 — Lavender is not one of them. The Finerenone interaction page linked on this page lists every one, ranked by severity.
