About Tianeptine
Tianeptine is an atypical antidepressant that acts on opioid receptors at high doses and has been sold as a supplement in some markets. It is not part of standard employment panels.
At high doses it may cross-react on some opioid immunoassays; confirmation by mass spectrometry resolves the result.
Because it is not a standard analyte, a negative routine panel does not rule out use.
False positives & cross-reactivity
- High-dose tianeptine has been reported to interfere with some opioid immunoassays — confirmation resolves it.
