Drug & supplement interaction

Gentian + 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 Gentian 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.

Gentian 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 Gentian 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.

Gentian safety at a glance

Gentian overall Use caution Generally tolerated in small amounts by healthy adults, but it can upset the stomach and is not well studied at high doses.
Pregnancy Avoid Not enough safety data, and traditional cautions exist, so it is best avoided during pregnancy.
Breastfeeding Avoid There is not enough reliable safety information, 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 Darolutamide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Darolutamide is filed under 3 classifications — p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Gentian has documented interactions with 1 drug class — the most serious being antihypertensive drugs (moderate) — and none of Darolutamide’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 Gentian and Darolutamide 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.

  • Reduced appetite / Diarrhea / Nausea reported in 4.3% of FDA reports for Darolutamide Additional detail

    Gentian

    “Orally, gentian root, in combination with other herbs, has been reported to cause gastrointestinal adverse effects. Gastrointestinal intolerance occurred in patients with cancer-associated anorexia who took gentian tincture 1 mL three times daily, in conjunction with turmeric 1 gram and ginger 1 gram twice daily, for 14 days.”

    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 Gentian but not commonly for Darolutamide: vomiting and bloating or gas.

Effects for Darolutamide come from the ADVERSE REACTIONS section of its FDA label; effects for Gentian 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 — Gentian Should Not Break It

At least one FDA label for a product containing Darolutamide says to take it with food. If you take Gentian 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.

Overlapping uses

What Darolutamide Is Prescribed For, and What Gentian Has Been Studied For

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

Darolutamide is prescribed for: 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.

Gentian has been studied for:

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

    Gentian for cancer

    Although there has been interest in using topical gentian for cancer, there is insufficient reliable information about the clinical effects of gentian for this purpose.

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 Darolutamide on your own; if you are taking Gentian for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Darolutamide

This page covers Gentian only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Darolutamide page lists 144 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 · 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 Gentian

What is Gentian?

  • Loss of appetite
  • Indigestion and bloating
  • Digestive bitter tonic
  • Stomach upset
  • Sluggish digestion

Gentian is a very bitter root traditionally used to stimulate appetite and ease mild digestive complaints, often as part of "bitters" before meals. The evidence is mostly traditional and preliminary, and while short-term use of normal amounts appears generally well tolerated in healthy adults, anyone with ulcers, reflux, or who is pregnant should be cautious and check with a pharmacist or doctor first.

Gentiana lutea · Gentianaceae · Root and rhizome · Tinctures, liquid extracts, teas, bitters, capsules, dried root

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

Gentian: dosing

There is no official, standardized dose for gentian, and products vary widely in strength. Traditional use involves small amounts of a tincture, extract, or tea taken shortly before meals.Because formulations differ, the safest approach is to follow the directions on the product label and not exceed the suggested amount. A pharmacist can help you choose a reasonable product and dose, and can review it against your other medicines and health conditions.

Taking Gentian and Darolutamide Together: Common Questions

Is it safe to take Gentian with Darolutamide?
We do not list a known interaction between Gentian 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 Gentian and Darolutamide have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Gentian 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 Gentian 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.
Are Gentian and Darolutamide 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 Gentian in each. That is a conversation for your prescriber, especially if Darolutamide is being adjusted to a target.
How was the Gentian and Darolutamide combination checked?
Interactions in our licensed database are recorded against drug classes. Darolutamide is filed under 3 classifications, and Gentian has documented interactions with 1 drug class — none of Darolutamide'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 Gentian interact with any other medications?
Yes. Gentian has 172 documented drug interactions in our database — Darolutamide 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 Darolutamide interact with any supplements?
Yes. Darolutamide has documented interactions with 144 supplements in our database — Gentian is not one of them. The Darolutamide interaction page linked on this page lists every one, ranked by severity.
