What causes a false positive for hydrocodone in
My doctor recently took a drug test and it came out positive for hydrocodone. She said I am getting prescriptions from some one else and does not want me to come back to her practice. The only medications I take I get from her. I have fibromyalgia and am taken the follow medications prescribe by my doctor, trazadone, effexor, estrogen, endocet (perocet), oxycontin, iron pills, ondansetron, albuterol,astelin and thyroxin.
