Hi, I Took One Of My Husband's Sleeping Pills (trazodone)

Hi, I took one of my husband's sleeping pills (trazodone) the other day to help me sleep and I am having to take a hair follicle drug screen for a job soon. I was wondering if it will possibly make me fail the test. I work 3rd and I have trouble sleeping during the day so I like that they help me sleep and wanted to continue to take them if they do not show up on the drug screen.
