My Dr does regular urine tests on me.
I am prescribed Oxycodone 30, Fent patch, and Lyrica monthly. I take the Oxy only as breakthru PRN only. Some days if I can avoid it I definitively do.
Last visit I was told there was no evidence of the Oxy in my system last 2 urine tests (1 month apart). He told me the Oxy should remain in urine for several days, depending on my metabolism.
He then quizzed me what's up?
I replied with an, "gee I don't get it either, but was wondering myself. Is it totally unusual?
