I am a 22 year old mother of a 22 month old little girl. I am a full time nursing student and I am a part time sales associate at a local Radio Shack.

On November the 7th I was given a 'random' drug test by the school of nursing. On the next day I attended my first clinical. At lunch time I was informed by the instructor to go see the division chair at the Jasper campus, Ms. R*. When I arrived at the nursing building, I was approached by another instructor, Mrs. C* who proceeded to inform me that I had a positive drug test, and asked me if I take any prescription medications. To which I informed her that I take 40 mg of prozac. So I go a copy of the prescription, and by then I was able to talk to Ms. R*. She informed me that I had tested positive for Benzodiazapines. I basically told her that's impossible, so here's the question: How can Prozac, dyphenhydramine (Benedryl which is OTC), and Tri-Levelen (birth control pills) cause a false positive for benzodiazapines????
