I took 1 (one) 50mg tramadol hcl. Will it show up on a drug screen for a job? I don't take them daily.

As . As far as I am aware tramadol will not give a positive drug screen. However, there are reports that people taking tramadol may test positive for opiates. If you are concerned, you can get a note explaining this possibility from the doctor that prescribed you the tramadol. Good luck.
