A substance moving quietly through convenience store aisles and gas station checkout counters has caught the attention of federal health officials, emergency room physicians, and state lawmakers — and the response is accelerating.
Tianeptine, a tricyclic antidepressant never approved for any use by the U.S. Food and Drug Administration, carries a street name that cuts straight to the point: “gas station heroin.”
Fourteen states have had enough.
Each has formally placed the substance under Schedule I classification, the most restrictive category in controlled substance law.
Connecticut joined that list this week, becoming the latest state to shut the door on tianeptine sales and use entirely.
The FDA has put the drug’s potency on record — at elevated doses, it surpasses morphine and rivals the most addictive opioids known to medicine.
Nations where tianeptine holds legal prescription status have already moved to overhaul their warning labels, explicitly cautioning patients about the drug’s addictive grip.
The Drug Enforcement Administration draws a clear line on what misuse looks like in practice: respiratory failure, extreme sedation, and in the worst cases, death.
Sellers have positioned the product as a wellness tool — a fix for pain, anxiety, and depression, or a mental sharpness booster — offering it in pill, powder, salt, and liquid form under brand names including Tianaa, ZaZa, Neptune’s Fix, Pegasus, and TD Red.
Connecticut Lt. Gov. Susan Bysiewicz didn’t mince words on how victims ended up harmed.
“With false marketing that led consumers to believe these are safe products, and with candy-like flavor options, these substances posed a clear threat to those battling substance-use disorder and our youngest residents,” she said, Fox News reported.
Connecticut’s crackdown extended beyond tianeptine alone.
Kratom, 7-hydroxymitragynine, Bromazolam, Flubromazolam, Nitazenes, and Phenibut all landed on the state’s new controlled substance list in the same action.
FDA Commissioner Martin Makary took the rare step of writing directly to the public earlier this month, using pointed language to frame the stakes.
“I am very concerned,” Makary wrote, per Fox.
“I want the public to be especially aware of this dangerous product and the serious and continuing risk it poses to America’s youth.”
Dr. Robert Schwaner, vice chair of system clinical affairs at Stony Brook Emergency Medicine in New York, confirmed the FDA has never cleared the drug for dietary supplement use — a classification some sellers have leaned on to stock it legally.
“The euphoria at low doses is primarily due to increased serotonergic activity from its serotonin reuptake effects. With increasing doses, the mu-opioid receptor stimulation may become lethal,” Schwaner said.
The physician walked through the chain of events that makes the drug a potential killer.
“As with heroin and other opioids, significant mu-opioid receptor stimulation ultimately results in a loss of respiratory drive and subsequent cardiac arrest,” he stated.
Schwaner argued that state-by-state action is not enough.
“Acting at the same receptor as opioids, tianeptine has the potential for an individual to develop tolerance, subsequent dependence and withdrawal from its use,” he warned, making the case for a federal solution.
Bipartisan federal legislation — the STAND Against Emerging Opioids Act — has been introduced in Congress and would place tianeptine and its chemical relatives under Schedule III of the federal Controlled Substances Act, mandating a prescription for any legal access.
