May 14, 2025 – The US Food and Drug Administration (FDA) has issued a stern warning regarding the use of tianeptine, a substance increasingly found in products sold at gas stations, convenience stores, vape shops, and online retailers. Commonly referred to as “gas station heroin,” tianeptine has been linked to a growing number of serious health incidents, including fatalities.
Rising Health Concerns
The FDA’s warning comes amid reports of adverse events associated with tianeptine, such as coma, agitation, confusion, high blood pressure, respiratory depression, rapid heart rate, vomiting, and even death. The agency described the use of tianeptine as “a dangerous and growing health trend facing our nation,” particularly among young people.
What Is Tianeptine?
Tianeptine is licensed as an atypical antidepressant in some countries, where it is prescribed in controlled doses (typically 12.5 mg three times daily). However, the FDA has not approved tianeptine for any medical use in the United States, nor is it scheduled under the Controlled Substances Act. It is not considered safe in food or as a dietary supplement.
Despite this, tianeptine is often marketed in the US as a “research chemical,” “nootropic” cognitive enhancer, or dietary supplement. Products containing tianeptine are sold under various names, including Tianaa, Zaza, Neptune’s Fix, Pegasus, and TD Red.
Misuse and Overdose Risks
While approved doses in other countries total 37.5 mg per day, the FDA has received reports of US consumers ingesting amounts ranging from 50 mg to an alarming 10,000 mg. The pursuit of euphoria at higher doses has led to increased restrictions and warnings about addiction in countries where tianeptine is prescribed.
Regulatory Actions
The FDA has issued warning letters to companies distributing and selling tianeptine-containing products and has implemented an import alert to help detain shipments at US borders. The agency urges healthcare professionals to discuss the dangers of these products with patients and to encourage their avoidance. Additionally, tianeptine may not be detected in routine drug screenings, complicating diagnosis and treatment in cases of overdose.
What To Do If You Suspect Adverse Effects
Anyone experiencing or witnessing a suspected adverse reaction to tianeptine should contact PoisonHelp.org and report the incident to the FDA’s MedWatch website.
