Hi, I was prescribed Mucinex D by my PCP on 6/24/14 for a severe sinus infection, along with Levaquin for an antibiotic. I stopped taking the Mucinex when the congestion was gone, about 4 to 5 days ago. Tomorrow 7/8/14, I m taking a pre-employment drug screen, will the pseudoephedrine component show up in the urine test as an opiate?
