Drug & supplement interaction

Gamma-linolenic Acid (gla) + Darolutamide

Darolutamide brand name: Nubeqa.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Gamma-linolenic Acid (gla) 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.

Gamma-linolenic Acid (gla) 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 Gamma-linolenic Acid (gla) 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.

Gamma-linolenic Acid (gla) safety at a glance

Gamma-linolenic Ac... overall Use caution Usually well tolerated, but quality and source of the oil matter and some people have side effects.
Pregnancy Avoid Not enough safety data; some sources are traditionally avoided in pregnancy, so it is best to avoid.
Breastfeeding Use caution Safety is not well established, so check with your doctor before use.

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. Gamma-linolenic Acid (gla) has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet 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 Gamma-linolenic Acid (gla) 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. One of them is worth acting on rather than waiting out — marked below.

Reported for Gamma-linolenic Acid (gla) but not commonly for Darolutamide: bloating or gas, stomach upset and vomiting.

Effects for Darolutamide come from the ADVERSE REACTIONS section of its FDA label; effects for Gamma-linolenic Acid (gla) 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 — Gamma-linolenic Acid (gla) Should Not Break It

At least one FDA label for a product containing Darolutamide says to take it with food. If you take Gamma-linolenic Acid (gla) 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

This page covers Gamma-linolenic Acid (gla) 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 Gamma-linolenic Acid (gla)

What is Gamma-linolenic Acid (gla)?

  • Eczema and dry skin
  • Rheumatoid arthritis
  • Diabetic nerve pain
  • PMS and breast pain
  • Menopausal symptoms

Gamma-linolenic acid (GLA) is an omega-6 fatty acid found in oils like evening primrose and borage. It is most studied for skin conditions, joint pain, and nerve pain, but the evidence is mixed and far from conclusive. It is generally well tolerated, but talk with your pharmacist or doctor before starting, especially if you are pregnant, breastfeeding, or take other medicines.

Seed oil (from evening primrose, borage, or black currant seeds) · Capsules, softgels, and oils (evening primrose oil, borage oil, black currant seed oil)

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

Gamma-linolenic Acid (gla): dosing

There is no single official or standardized dose of GLA. The amount of GLA varies depending on the source oil, since evening primrose, borage, and black currant seed oils contain different concentrations.Because products differ so much, the best approach is to follow the directions on the product label and choose a reputable brand. A pharmacist can help you compare products and figure out an appropriate amount for your situation.Do not assume more is better.

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

Taking Gamma-linolenic Acid (gla) and Darolutamide Together: Common Questions

Is it safe to take Gamma-linolenic Acid (gla) with Darolutamide?
We do not list a known interaction between Gamma-linolenic Acid (gla) 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 Gamma-linolenic Acid (gla) 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 Gamma-linolenic Acid (gla) 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 Gamma-linolenic Acid (gla) 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.
How was the Gamma-linolenic Acid (gla) and Darolutamide combination checked?
Interactions in our licensed database are recorded against drug classes. Darolutamide is filed under 3 classifications, and Gamma-linolenic Acid (gla) 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 Gamma-linolenic Acid (gla) interact with any other medications?
Yes. Gamma-linolenic Acid (gla) has 122 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 — Gamma-linolenic Acid (gla) is not one of them. The Darolutamide interaction page linked on this page lists every one, ranked by severity.
