I am not on benzodiazepines. I take trileptal, an antiseziere medicine
and trazodone, for depression. I took coricidin D and ibuprofen as
well, but was not on and benzo's. I get tested twice a month. This was
the only positive. How should I go about dispuing the test?  Jeanne

Had you taken Serax (oxazepam) within a couple of weeks of the drug
screen?  Or is there anyone in your household who takes it?

Also, you could ask your employer to retest you.  Perhaps it was a false positive.
