Key Takeaways
- Tianeptine is not approved for any medical use in the United States, yet it is sold at gas stations, smoke shops, and online as a supplement or nootropic.
- Research shows tianeptine acts on opioid receptors, which is why regular use can lead to opioid-like dependence, withdrawal, and overdose.
- The FDA has linked tianeptine products to seizures, loss of consciousness, hospitalizations, and deaths, and some products have contained unlisted synthetic cannabinoids.
- In July 2026 the DEA proposed placing tianeptine in Schedule I, while a 2025 Texas bill to control it passed the Senate but did not become law.
- Treatment generally follows opioid use disorder principles and should also address the depression or anxiety that tianeptine may have been masking.
The bottle might say Tianaa, Zaza, Pegasus, or Neptune’s Fix. It might be shelved near energy shots at a gas station or sold online as a mood or focus supplement. What it often contains is tianeptine, a drug never approved for any medical use in the United States, now widely known as “gas station heroin.” Tianeptine addiction tends to sneak up on people, because the product looks legitimate and the early effects feel like relief. This guide explains what tianeptine is, why it is dangerous, what withdrawal looks like, and how treatment works. For the program itself, see our opioid addiction treatment in Houston page.
Most people who end up dependent on tianeptine did not set out to use an opioid. Many were looking for help with anxiety, low mood, or energy. That context matters, because good treatment has to address both the drug and whatever it was being used to manage.
Tianeptine, defined: a compound used as an antidepressant in some countries in Europe, Asia, and Latin America, but not approved by the FDA for any medical use. Research shows it acts on the brain’s opioid receptors, which explains both its appeal at high doses and the opioid-like dependence and withdrawal people experience.
What Is Tianeptine, and Why Is It Called Gas Station Heroin?
Tianeptine is sold in the United States as a “research chemical,” a nootropic, or a dietary supplement, even though the FDA has said it is not a lawful dietary ingredient. The FDA has documented it in convenience stores, gas stations, vape and smoke shops, and online retailers. The nickname comes from that combination: easy availability and opioid-like effects.
The CDC reported years ago that tianeptine acts as an opioid receptor agonist, and that poison center calls involving tianeptine rose sharply in the mid-2010s. In July 2026, the DEA proposed placing tianeptine in Schedule I of the Controlled Substances Act, citing a high potential for abuse, no accepted medical use in the United States, and reports of overdose deaths, including two in Texas. As of this writing, that proposal had not been finalized. A 2025 Texas bill that would have added tianeptine to the state’s controlled substances law passed the Senate but did not become law, so its legal status in Texas depends on federal action and any future state legislation. This is general information, not legal advice.
The Risks of Tianeptine Use
The FDA has warned consumers not to buy or use any tianeptine product. Its warnings describe seizures, loss of consciousness, hospitalization, and death after use. Case reports describe people in the United States taking amounts that vary enormously from person to person, which reflects how quickly tolerance builds.
Some products are not even what they claim to be. In 2023, a cluster of severe illness in New Jersey was linked to Neptune’s Fix products. The CDC reported that 17 patients developed altered mental status, many with fast heart rates, low blood pressure, or seizures; 13 were admitted to intensive care, and testing of product samples found synthetic cannabinoids that were not on the label. The FDA has warned that some tianeptine products may contain harmful ingredients that are not listed.
Key risks include:
- Opioid-like overdose, including slowed or stopped breathing
- Seizures and heart rhythm problems
- Hidden ingredients that change how a product affects the body
- Dangerous interactions with alcohol, benzodiazepines, and other medications
- Rapid tolerance and physical dependence
| What the label suggests | What the evidence shows |
|---|---|
| A dietary supplement or nootropic | Not a lawful dietary ingredient, according to the FDA, and not approved for any medical use in the U.S. |
| A mood or focus aid | Acts on opioid receptors, with dependence and withdrawal that resemble opioid use disorder |
| A consistent, labeled product | Some products have contained unlisted ingredients, including synthetic cannabinoids |
| Low risk because it is sold openly | Linked to seizures, loss of consciousness, hospitalizations, and deaths |
Integrated Dual Diagnosis Care
Can’t stop taking it?
Tianeptine dependence is treatable, and a confidential assessment is a good first step.
Tianeptine Withdrawal Symptoms
Tianeptine withdrawal resembles opioid withdrawal. In poison center data reviewed by the CDC, the most common withdrawal signs included agitation, nausea, vomiting, a racing heart, high blood pressure, diarrhea, tremor, and sweating. People also describe intense anxiety, low mood, insomnia, and strong cravings.
Withdrawal can begin within hours for people who dose frequently, which is why so many feel trapped in a cycle of buying and taking more. Severity varies widely, and people who also use alcohol, benzodiazepines, or other substances can face a more complicated withdrawal. Some people need a medically supervised setting to stop safely; others can be managed with outpatient medical care. The decision depends on a full clinical picture, not on willpower.
Tianeptine Addiction Treatment
Because tianeptine acts like an opioid, many clinicians approach tianeptine dependence using the same principles as opioid use disorder. Published research on tianeptine treatment is limited, much of it case reports, so care should be individualized and honest about what is and is not known.
A sound treatment plan usually includes:
- A thorough assessment of how much tianeptine is being used, how often, and what else is in the picture
- A withdrawal plan, with referral to supervised detox when risk is higher
- A conversation with a prescriber about whether medication for opioid use disorder, such as buprenorphine, makes sense; case reports describe its use for tianeptine dependence
- Treatment for the depression, anxiety, or trauma that tianeptine may have been masking
- Structured outpatient care, such as partial hospitalization or intensive outpatient programming, to rebuild routines
The mental health piece deserves emphasis. Tianeptine is marketed as a mood aid, and many people find their way to it after antidepressants did not work or felt out of reach. Stopping tianeptine can unmask the depression or anxiety it was quieting. Integrated dual diagnosis treatment treats both at the same time, which tends to hold better than treating them one after another.
Tianeptine, Other Drugs, and Overdose Safety
Tianeptine is rarely the only substance in the picture. People who use it may also use kratom, alcohol, sedatives, or stimulants, and our guide to polysubstance use explains why combinations raise risk. If you have used kratom alongside tianeptine, our article on kratom safety may also help.
The CDC has reported case reports in which tianeptine toxicity looked like opioid toxicity and naloxone was effective. Families of someone using tianeptine may want to keep naloxone at home. Standard harm reduction advice applies: do not use alone, and call 911 if someone cannot be woken or is breathing slowly.
How Heights Can Help
Heights Behavioral Health is an outpatient practice in the Houston Heights. We do not provide detox, but we assess withdrawal risk, coordinate referrals when supervised withdrawal is needed, and offer substance use treatment that includes partial hospitalization, intensive outpatient programs with evening options, individual and group therapy, family programming, and medication-assisted treatment with buprenorphine or naltrexone where clinically appropriate.
Crisis notice. If someone has a seizure, is unresponsive, or is breathing slowly after taking tianeptine, call 911 now and give naloxone if available. For poisoning questions, call Poison Help at 1-800-222-1222. Heights Behavioral Health provides scheduled outpatient care and is not an emergency or detox service. If you are in crisis, call or text 988.
Frequently Asked Questions
Is tianeptine an opioid?
Tianeptine is not chemically classified as a traditional opioid, but research shows it acts on opioid receptors. At the amounts people often use, it produces opioid-like effects, dependence, and withdrawal.
Is tianeptine legal in Texas?
A 2025 Texas bill to make it a controlled substance did not become law, and in July 2026 the DEA proposed placing tianeptine in federal Schedule I. The FDA already considers tianeptine products unlawful as supplements. The legal picture is changing, so check current sources.
How long does tianeptine withdrawal last?
It varies with how much and how long someone has used. Acute symptoms often resemble opioid withdrawal, and mood and sleep problems can linger longer. A clinician can help predict the course and plan support.
Can buprenorphine help with tianeptine withdrawal?
Case reports describe buprenorphine being used for tianeptine dependence. Evidence is limited, so the decision should be made individually with a prescriber who knows your full history.
