I'm prescribed 15mg of oxycodone every 6 hrs and this month I ran out early. My appointment is coming up soon, and at my pain management doctors office they usually do a UA to make sure I'm taking my medication and only that. I actually have one of my old 20mg oxycontin pills and I know they show up the same on a UA but my question is: Will it be enough? I'm sure it will show up positive for oxycodone but will the level be strong enough if I take it the morning of my appointment? Any answers will be appreciated
