Tianeptine and Ozanimod Hydrochloride

Here is the interaction we found between these two, with the evidence behind it.

Major

MONOAMINE OXIDASE INHIBITORS (MAOIs)

Why this applies to Ozanimod Hydrochloride

Ozanimod Hydrochloride falls under MONOAMINE OXIDASE INHIBITORS (MAOIs) — the group Tianeptine interacts with.

Tianeptine may increase the toxicity of MAOIs.
Concomitant use of tianeptine and non-selective MAOIs might increase the risk of cardiovascular collapse, hypertension, fever, convulsions, and death.
Severity Major Likelihood Probable Evidence C

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's something worth knowing about Zeposia (ozanimod). One of the breakdown products of this MS and ulcerative colitis drug actually blocks an enzyme called MAO (monoamine oxidase). That's why it gets grouped with MAO inhibitors when we check for interactions. Tianeptine, on the other hand, is an unapproved substance often sold illegally in 'gas station' products, and combining it with something that has MAO-blocking activity is a real concern.

When you slow down MAO and add tianeptine, the worry is a dangerous buildup that can lead to spikes in blood pressure, fever, seizures, and in the worst cases cardiovascular collapse. This is flagged as a major, serious combination. Please don't use any tianeptine product, and talk with your doctor or pharmacist about anything you're taking alongside Zeposia.

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.
