Hello, I have a drug screening coming up on Friday, January 30, at 10:00am. I was just prescribed a Fentanyl patch for Crohn's disease, which I need badly (constant diarrhea, abdominal pain etc.). I'd prefer my employer to be does not know about this condition, so I took the patch off (25 mug) just now. Will it show up in urine sample taken on Friday? Does employer even care? I am an attorney and do legal auditing. Doctor also gives me oxycodone (10 mg imm rel for breakout; 1-2 for breakout, every 6 hours, max = 6 per day) How long to flush both out? Thanks SO much! :)
