I do pain management and take oxymorphone, I lost my bottle and will more then likely have a drug test at my next appointment. Rather then get sick I found some H doesbt it show up as morphine in so many hours? It will be four days since my last dose of prescribed meds. I might have to come up with a story so I need my facts straight and if it does turn to morphine I need to know how many hours to wait before my last hit and my test.
