I took one of my moms Fiorecet 4 days ago for a migraine headache I wa having, I have never taken this medication before. I got a promotion at my job and guess what... You have to take a drug screen. Just wondering if I will pass. I drink plenty of water and I never take medications that is not mine, but this time I did desperate to get rid of a migraine. I'm a nurse so I know the typical meds but Fiorecet/barb's I'm not as familiar with. Thank you!
