Yes, Effexor (venlafaxine) can potentially cause a false positive for methadone in urine drug tests. This is due to its chemical structure and the way certain drug tests are designed, which can sometimes misidentify substances. However, confirmatory testing, such as gas chromatography-mass spectrometry (GC-MS), can help differentiate between the two substances. If there are concerns about drug testing accuracy, it's important to inform the testing facility about all medications being taken.
