I know what Percoset is, it has 325 mg of Tylenol with 5 mgs Oxycodone. What I'm referring to is Roxicodone. It comes in tablet form 5, 15, and 30 mg strengths. I know because I've had all of them to use as breakthrough medication when I was on Oxycontin. This is pure Oxycodone with nothing else in it. Check with your pharmacy, where you get your scripts filled. They may have to look it up, but I know without a doubt it is available.
