I think you are getting bits and pieces of information that could be taken as misinformation. In general, oxy- and Roxy-/Roxi- DO refer to the same medication, albeit in different strengths.
It is true that oxycodone is the drug in question, Percocet being the brand name of a common formulation containing that drug combined with APAP (acetaminophen). Roxycodone, however, refers to a generic form of oxycodone (without APAP) marketed by Roxane Labs.
This thread illustrates a good point: why rely on incomplete or misinterpreted info from online sources regarding your health? A quick discussion (either f2f or via telephone) with a pharmacist would be far more reliable!
