Drug & supplement interaction

Mezereon + Darolutamide

Darolutamide brand name: Nubeqa.

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 Mezereon and Darolutamide 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 label for Darolutamide states a food rule worth keeping to, and 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.

Mezereon and Darolutamide

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 Darolutamide and Mezereon 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 Mezereon at all — not against Darolutamide, 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.

No Interaction Found — But Data Suggests Mezereon and Darolutamide 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.

  • Diarrhea reported in 4.3% of FDA reports for Darolutamide Additional detail

    Mezereon

    “Orally, mezereon can cause reddening and swelling of the oral mucous membranes, salivation, thirst, stomach pains, vomiting, and severe diarrhea (18).”

    Darolutamide

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

Reported for Mezereon but not commonly for Darolutamide: stomach pain, a fast or pounding heartbeat, dizziness and vomiting.

Effects for Darolutamide come from the ADVERSE REACTIONS section of its FDA label; effects for Mezereon come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 5,501 voluntary FDA FAERS reports for Darolutamide 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.

How to take them

Some Darolutamide Products Have a Food Rule — Mezereon Should Not Break It

At least one FDA label for a product containing Darolutamide says to take it with food. If you take Mezereon on an empty stomach out of habit, keep them separate — and take Darolutamide with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Darolutamide products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Take NUBEQA with food.

From the Dosage and Administration section of the FDA label we read for Darolutamide — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Everything else you take

See Every Supplement That Interacts With Darolutamide

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 · 103 moderate · 38 minor.

From our pharmacist’s overview on the Darolutamide page

“Darolutamide (Nubeqa) treats prostate cancer, and supplements deserve real caution alongside it, because most of those listed here can change how much of the drug stays in your blood. Nearly all act on CYP3A4, the liver enzyme that breaks darolutamide down, or on the transport proteins that move it through cells.”

About Mezereon

What is Mezereon?

  • Skin conditions and ulcers (traditional)
  • Joint and rheumatic pain (traditional)
  • Counter-irritant on the skin
  • Homeopathic remedies for skin eruptions

Mezereon is a poisonous European shrub whose bark and berries have been used in traditional and homeopathic medicine, but it is highly toxic and irritating. There is no reliable scientific evidence that it safely treats any condition, and swallowing any part of the plant can be dangerous. It should not be used as a home remedy.

Daphne mezereum · Thymelaeaceae · Bark and berries (rarely the dried bark used in traditional preparations) · Homeopathic preparations, traditional tinctures, and topical ointments

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

Mezereon: dosing

There is no established safe dose of mezereon for any medical use. Because the plant is poisonous, pharmacists and doctors do not recommend taking it.Highly diluted homeopathic products are sometimes sold, but these are not proven to work, and you should never use raw bark, berries, or homemade tinctures.

About Darolutamide

What Is Darolutamide Used For?

Brand name: Nubeqa

Nubeqa (darolutamide) tablets are approved for adult men with two forms of advanced prostate cancer. The first is non-metastatic castration-resistant prostate cancer (nmCRPC) — cancer that keeps growing despite hormone-lowering therapy and has not yet spread to other parts of the body. The second is metastatic castration-sensitive prostate cancer (mCSPC) — cancer that has spread but still responds to hormone-lowering treatment.

For mCSPC, Nubeqa can be used alone or in combination with docetaxel (a chemotherapy medicine). In all cases, patients also receive a gonadotropin-releasing hormone (GnRH) agonist or antagonist — a medicine that lowers testosterone — or have already had surgery to remove the testicles.

Most-Reported Side Effects for Darolutamide

From FAERS, the FDA’s public side-effect reporting system (5,501 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 829 reports
Hot flush 622 reports
Asthenia 352 reports
Dizziness 236 reports

Taking Mezereon and Darolutamide Together: Common Questions

Is it safe to take Mezereon with Darolutamide?
We do not list a known interaction between Mezereon and Darolutamide. 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 Mezereon and Darolutamide 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.
Should I take Mezereon and Darolutamide at the same time of day?
At least one FDA label for a product containing Darolutamide says to take it with food. If you take Mezereon on an empty stomach out of habit, keep them separate and take Darolutamide with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Darolutamide products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Darolutamide interact with any supplements?
Yes. Darolutamide has documented interactions with 144 supplements in our database — Mezereon is not one of them. The Darolutamide interaction page linked on this page lists every one, ranked by severity.
