No, diazepam is a benzodiazepine whereas Requip is an
anti-Parkinson's drug. Requip works primarily on dopamine receptors
in the central nervous system. Diazepam works on benzodiazepine
receptors on GABA neurons. It is thought that Requip may have
negligible activity at other GABA sites, but this is not its main
mechanism of action. In terms of toxicity screen, I have not found
data stating that Requip will give a false positive for benzos.
High concentrations of fenoprofen, flurbiprofen, indomethacin,
ketoprofen, and tolmetin (these are NSAIDS) may give a
false-positive result by a TDx assay. Sertraline (Zoloft) may cause
a false-positive urinary benzodiazepine assay using the original
cloned enzyme donor immunoassay system
