[11/21/2023] FDA is warning consumers to not 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.

FDA has received severe adverse event reports after use of Neptune‘s Fix products, including seizures and loss of consciousness leading to hospitalization. Consumers who experience a bad reaction to any tianeptine product should seek immediate medical help.

Neptune Fix’s labels state the product contains tianeptine, but may contain other harmful ingredients not listed on the label. These products, like other tianeptine products, can be purchased online and at gas stations, vape or smoke shops, or other locations. FDA is testing these products and will provide more information as it becomes available. FDA also continues to warn consumers about risks of using tianeptine.

Health care professionals and consumers should report adverse events or side effects related to the use of this product to FDA's MedWatch Safety Information and Adverse Event Reporting Program:

• Complete and submit the report online at MedWatch Online Voluntary Reporting Form, or;
