Tianeptine is not approved by the U.S. Food and Drug Administration for any medical use. Despite that, some companies are illegally marketing and selling products containing tianeptine to consumers. They are also making dangerous and unproven claims that tianeptine can improve brain function and treat anxiety, depression, pain, opioid use disorder, and other conditions.
In the U.S., reports of severe side effects involving tianeptine are increasing. Poison control center cases involving tianeptine exposure have increased nationwide, from 11 total cases between 2000 and 2013 to 151 cases in 2020 alone.
