Drug Test Cross Reaction Guide

Type the Drug Name or Brand in the Search Box to find out if it cross reacts or shows positive on a urine drug screen. Nonreactive in the Results column means the drug by itself is not tested for in a urine drug screen.

The following list of 653 drug names and compounds is not all-inclusive since other substances and/or factors may interfere with the test and can cause false results. All positive results from rapid drug test devices are presumptive and should be confirmed by a laboratory using an alternative methodology.
