Hello i took tramadol hcl then 7 to 8 hrs i had a drug test for work that was a five panel drug screen will this cause me to fail my drug test?

Drug test : As long as you indicated that you are taking this medication, and are taking this medication under a doctor's supervision, you should be fine.

No. Per literature..: Some Federal drug testing guidelines require the 5 panel test, which includes an opiate panel. The opiate panel tests for metabolites of codeine and morphine, neither of which are metabolites of Tramadol. While Tramdol's primary metabolite does bind to opiod receptors, it has a substantially different molecular structure. Standard screens will only detect heroin, codeine, and morphine.
