I am currently on Cryselle (birth control), levalbuterol (inhaler) as needed, I take melatonin to help me sleep (has a Stevia extract), I take one a day women's vitamins, and a temporary UTI drug (Bactrim). I am currently in school to become an MA and have never used any sort or anti anxiety or calming drugs like a benzo. However, when the class was drug tested today mine came back positive for benzo and I am trying to figure out why. I don't take any recreational drugs and I never have, and quite honestly I'm a bit on edge with this whole thing. I just need some help trying to find out what may have happened. I haven't been able to find much of anything as for drug interactions that would cause that. I am still researching and trying to figure this all out. Any thing you may have to help me understand how this happened would be greatly appreciated.
