4 ti 8 =hrs after taking it. prescription would help.

If you have been prescribed this medication by your doctor and can take information showing that this was prescribed to you at the time of your drug screening then this won't be held against you. They are only looking for illegal drugs and prescription drugs that you haven't been prescribed to take. But if a controlled substance is in your system that a doctor did in fact prescribe to you then you CAN NOT get in any trouble/or be with held a job for that.
