FDA Issues Another Warning on Tianeptine Products, Which Can Cause Seizures and Death

January 25, 2024


Reiterating a warning first issued in November, the U.S. Food and Drug Administration is urging Americans to stay away from supplements containing tianeptine, known on the street as “gas station heroin.”

The supplements, sold under the brand name Neptune’s Fix online and at gas stations and convenience stores, can cause seizures, unconsciousness and even death.

“FDA is warning consumers not to purchase or use any Neptune’s Fix products, or any other product with tianeptine — a potentially dangerous substance that is not FDA-approved for any medical use but is illegally sold with claims to improve brain function and treat anxiety, depression, pain, opioid use disorder and other conditions,” the agency said in its November statement.
