Drug & supplement interaction

Tianeptine + 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 Tianeptine 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

Tianeptine 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 Tianeptine 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. Tianeptine has documented interactions with 4 drug classes — the most serious being monoamine oxidase inhibitors (maois) (major), alcohol (ethanol) (moderate) and aspirin (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 Tianeptine 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. 2 of them are worth acting on rather than waiting out — marked below.

  • Seizures Worth acting on Additional detail

    Tianeptine

    “Orally, tianeptine can cause insomnia, drowsiness, dizziness, and headache when used in prescription doses (25-37.5 mg daily). Orally, recreational use of tianeptine has been associated with agitation, anxiety, confusion, drowsiness, and seizures. In one case, tianeptine misuse was linked to toxic leukoencephalopathy.”

Special populations

Tianeptine in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When used orally. Although tianeptine is approved as a prescription drug in certain countries and has been used during pregnancy under the guidance of a healthcare provider when medically necessary, its use is discouraged. Tianeptine use can lead to neonatal abstinence syndrome (NAS), especially when used recreationally, throughout pregnancy. In case reports, babies born to mothers taking high doses of tianeptine (e.g. 650 mg or more daily) during pregnancy presented with NAS. Symptoms included diarrhea, fever, frequent yawning and sneezing, global hypertonia, high-pitched crying, jitteriness, poor feeding, sweating, undisturbed tremors, vomiting, and weak or excessive sucking. This tianeptine-induced NAS mimicked opiate-induced NAS and was treated successfully with morphine.

Overlapping uses

What Duloxetine Is Prescribed For, and What Tianeptine 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. Tianeptine 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.

Age-specific approvals vary by product — follow your prescriber's guidance on which product is right for your age group.

Tianeptine has been studied for:

  • Depression Natural Medicines rates the evidence for Tianeptine: Possibly Effective Read what the research shows

    Tianeptine for depression

    Limited research shows that the efficacy of prescription doses of tianeptine in major depression is similar to that of selective serotonin reuptake inhibitors (SSRIs).

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

    Tianeptine for anxiety

    Although there has been interest in using oral tianeptine for anxiety, there is insufficient reliable information about the clinical effects of tianeptine for this condition.

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 Tianeptine for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Tianeptine

What is Tianeptine?

  • Depression (prescription use in some countries)
  • Anxiety
  • Mood enhancement
  • Pain relief
  • Self-treatment of opioid withdrawal
  • Recreational euphoria

Tianeptine is a prescription antidepressant in some countries, but it is NOT approved by the FDA in the United States and is illegally sold in dietary supplements and 'gas station' products. At high doses it acts like an opioid and carries serious risks of addiction, overdose, and dangerous withdrawal. We strongly advise against using over-the-counter tianeptine products and urge anyone considering it to talk with a doctor or pharmacist first.

Synthetic chemical compound (not a plant) · Tablets, capsules, powders, and liquid 'gas station' products

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

Tianeptine: dosing

There is no safe, established over-the-counter dose of tianeptine, and we do not recommend self-dosing with these products. In countries where it is a prescription antidepressant, a doctor sets the dose and monitors the patient closely.The amounts found in U.S. 'supplement' products are often unlabeled, inconsistent, or far higher than any medical dose — which is part of why they are so dangerous.

Taking Tianeptine and Duloxetine Together: Common Questions

Is it safe to take Tianeptine with Duloxetine?
We do not list a known interaction between Tianeptine 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 Tianeptine and Duloxetine have any of the same side effects?
Yes — our sources link each of them separately to 10 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 Tianeptine 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 Tianeptine in each. That is a conversation for your prescriber, especially if Duloxetine is being adjusted to a target.
How was the Tianeptine and Duloxetine combination checked?
Interactions in our licensed database are recorded against drug classes. Duloxetine is filed under 8 classifications, and Tianeptine has documented interactions with 4 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 Tianeptine interact with any other medications?
Yes. Tianeptine has 277 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 — Tianeptine is not one of them. The Duloxetine interaction page linked on this page lists every one, ranked by severity.
