question: Hi, I am a chronic pain patent and I take perc 10.325 every 6 hrs. Last nite I was in the ER with severe stomach pain and had been suffering all day. My pain med was not helping at all. The ER done some tests which one was a narcotic drug test, which I didn t care cause I knew I took my meds, but the test came back negative for narcotics...I knew this wasn t possible. The ER nurse said my enzymes are elevated...can that be the reason why my medicine doesn t seem to work or show up in a drug test? Can the elevated enzymes be pushing the narcotic thru my system to fast?
