Hi! I will be going under drug screen for a hospital job next week. My question is what type of drugs are they screening for? Do I need to disclose all of what I had taken in the past as well as PRN? I have never had to do this drug screen in any of my previous jobs but now I do. Will Viread (Not taken for HIV, taken for a different diagnosis) I have taken for nearly a year and stop a month ago show in my urine? How about taken Advil/Tylenol occasionally for headache? I have chronic headaches so I normally take Advil, Acetaminophen, or Tylenol whichever available. Never taken any stronger than these.
