My wife tested false positive for benzodiazepine and has been harassed trying to get her Norco 10/325 refilled. Her doctor refuses to believe it is false and has put her on a schedule to quickly wean her off Norco even after we alerted the doctor to a Lexapro cause. My wife has quit taking generic Lexapro after we looked its side effects up and its false positive tendencies, five days ago. She has numerous skeletal fractures, injuries and spondulosis, sp? Any suggestions on how to handle this dilemma. Is there any indisputable literature available to merit a more accurate test.
