We describe an adolescent patient who likely had a false-positive phencyclidine result detected with an 11-panel urine drug screen in an outpatient setting of long-term use of therapeutic venlafaxine extended release for the treatment of recurrent major depressive disorder and generalized anxiety disorder. We believe that this may be the first published case report to characterize this phenomenon in a young patient in the absence of an acute overdose.application/pdfenCreative Commons Attribution 4.0 InternationalArticle - Refereed2023-07-02Copyright © 2023 Hyun Sue Kim et al.
