is it a morphine derivitive or what. I have a prescription but would like to to know if asked what is
Fentanyl is fentanyl, thats what will show up. As long as you have a prescription it won't be a problem. Make sure you take it with you to the test...
Fentanyl is synthetic Heroin. It shows up as an opiate on your drug screen. And it also shows up EXACTLY in the amount of the opiate. Make sure to take your medication as directed and you'll be fine. :)
