I Was Administered Was Told Was A 5mg Red Small

I was administered was told was a 5mg red small tab called Roxycontin, IR and a 5mg oxycodone. I am taking regularly a 10 mg tab percocet or oxycodone. My doctor and I neither can find evidence of this Roxycontin or Roxycodone. Is there such a drug or have I the wrong spelling or true name?
