Drug & supplement interaction

Resveratrol + Duloxetine

Duloxetine brand names: Cymbalta, Drizalma Sprinkle, Irenka.

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 Resveratrol and Duloxetine 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.

Interaction report

Resveratrol and Duloxetine

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 Duloxetine and Resveratrol 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.

How we checked

Why No Interaction Is Listed for Duloxetine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Duloxetine is filed under 8 classifications — including antidepressant drugs, cytochrome p450 2d6 (cyp2d6) inhibitors, serotonergic drugs. Resveratrol has documented interactions with 5 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), cytochrome p450 1a2 (cyp1a2) substrates (moderate) and cytochrome p450 2c19 (cyp2c19) substrates (moderate) — and none of Duloxetine’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 Resveratrol and Duloxetine 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.

Overlapping uses

What Duloxetine Is Prescribed For, and What Resveratrol Has Been Studied For

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

Duloxetine is prescribed for: Duloxetine delayed-release capsules treat major depressive disorder (MDD) and generalized anxiety disorder (GAD) in adults. They also manage diabetic peripheral neuropathic pain (nerve pain from diabetes), fibromyalgia, and chronic musculoskeletal pain (such as chronic low back pain and pain from osteoarthritis) in adults. GAD is also approved in pediatric patients 7 years and older for Cymbalta, Drizalma Sprinkle, and certain duloxetine delayed-release capsule products. Fibromyalgia is approved in patients 13 years and older for Cymbalta and some duloxetine delayed-release capsule products.

Resveratrol has been studied for:

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

    Resveratrol for osteoarthritis

    It is unclear if oral resveratrol is beneficial for osteoarthritis.

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

About Resveratrol

What is Resveratrol?

Resveratrol
  • Heart and blood vessel health
  • Antioxidant support
  • Anti-aging
  • Blood sugar and metabolic support
  • General anti-inflammatory support

Resveratrol is a plant compound found in red grapes, berries, and peanuts that is popular for heart health, anti-aging, and antioxidant support. While lab and animal studies are promising, strong human evidence for most uses is still limited. It appears generally well tolerated in supplement doses, but talk with your pharmacist or doctor before starting it.

A plant compound found in grape skins, berries, peanuts, and Japanese knotweed · Capsules, tablets, softgels, powders

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

Resveratrol: dosing

There is no official standardized dose of resveratrol. Studies have used a wide range of amounts, and products on the market vary a lot in strength and quality.The best approach is to follow the directions on the product label and not exceed the recommended amount. Because supplements are not tightly regulated, choose products from reputable companies, ideally those that use third-party testing.

Taking Resveratrol and Duloxetine Together: Common Questions

Is it safe to take Resveratrol with Duloxetine?
We do not list a known interaction between Resveratrol and Duloxetine. 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 Resveratrol and Duloxetine have any of the same side effects?
Yes — our sources link each of them separately to 5 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.
Are Resveratrol and Duloxetine 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 Resveratrol in each. That is a conversation for your prescriber, especially if Duloxetine is being adjusted to a target.
How was the Resveratrol and Duloxetine combination checked?
Interactions in our licensed database are recorded against drug classes. Duloxetine is filed under 8 classifications, and Resveratrol has documented interactions with 5 drug classes — none of Duloxetine'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 Resveratrol interact with any other medications?
Yes. Resveratrol has 822 documented drug interactions in our database — Duloxetine 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 Duloxetine interact with any supplements?
Yes. Duloxetine has documented interactions with 132 supplements in our database — Resveratrol is not one of them. The Duloxetine interaction page linked on this page lists every one, ranked by severity.
