Thanks for this question

No, not likely.

It will show up as a general opiate in the opiate screen

Expert:  DrRussMD replied 1 year ago.

Hello

Percocette is oxycodone, with acetaminophen

It does not show up as a general opiate on a standard screen.

It requires a custom test.

If your doctor did a custom test, it will show up.

If you a prescribed this and took extra, it could raise your level, but that is not entirely accurate.

I am a double board certified US doctor.

Find me, dr. thomas, in medical anytime.

Please click a positive on my post.

Come back as needed.

I wanted to know if they would just think that the hydrochloride in my system is due to tizanidine hydrochloride, or if they would be able to tell that I took oxycodone hydrochloride. I am prescribe oxycodone
Expert:  Dr. Phil, MD replied 1 year ago.

They don't test for hydrochloride.

That won't show up regardless

Expert:  Family Physician replied 1 year ago.

Percocet contains oxycodone and acetaminophen

There is no way to determine if someone has taken plain oxycodone or the combination medication (Percocet) with urine or hair drug tests.

Both would be identified as oxycodone metabolites.
