Can Effexor or solian give a false positive test?

Effexor (venlafaxine) can potentially cause false positives on drug tests, particularly for amphetamines, due to its chemical structure. Solian (amisulpride) is less commonly associated with false positives, but it can still interfere with some tests. It's important to inform testing personnel about any medications taken to prevent misinterpretation of results. Always consult with a healthcare professional for specific concerns related to drug testing.
