Drug & supplement interaction

Tianeptine + Orlistat

Orlistat brand names: Xenical, Alli.

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 Tianeptine and Orlistat 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.

Tianeptine and Orlistat

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 Orlistat 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 Orlistat

Interactions in our licensed database are recorded against drug classes, not just single drug names. Orlistat is filed under 2 classifications — including oral 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 Orlistat’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 Orlistat 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.

    “Orally, tianeptine has been linked to cases of acute allergic hepatitis. It has also been associated with cholestatic or hepatocellular liver damage, occurring after 6 days to 8 weeks of tianeptine use.”

Showing the 10 most notable of 11 shared effects — ranked by how unusual each one is, not just whether both lists mention it.

Reported for Tianeptine but not commonly for Orlistat: dependence or withdrawal symptoms, raised blood pressure, constipation and a fast or pounding heartbeat.

Effects for Orlistat come from the ADVERSE REACTIONS section of its FDA label; effects for Tianeptine come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 25,755 voluntary FDA FAERS reports for Orlistat 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.

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.

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 Orlistat Together: Common Questions

Is it safe to take Tianeptine with Orlistat?
We do not list a known interaction between Tianeptine and Orlistat. 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 Orlistat 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.
How was the Tianeptine and Orlistat combination checked?
Interactions in our licensed database are recorded against drug classes. Orlistat is filed under 2 classifications, and Tianeptine has documented interactions with 4 drug classes — none of Orlistat'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 — Orlistat 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 Orlistat interact with any supplements?
Yes. Orlistat has documented interactions with 18 supplements in our database — Tianeptine is not one of them. The Orlistat interaction page linked on this page lists every one, ranked by severity.
