I take Lortab prescribed by my doctor. I am a nurse working at a nursing home. At change of shift, the on-coming nurse questioned a Morphine tablet. Said it "doesnt look right." The DON came & looked. She agreed the pill did not match the others. I was given a drug test. It was negative for Morphine, But... Positive for hydrocodone & OXYCODONE ! BUT I DO NOT TAKE OXYCODONE! WHAT TO DO?
