I went to my pain management Dr. today for my regular 3 month visit. He asked how my pain was being managed and I told him that the 30mg of Morphine once a day plus up to 4 Percocet 10/325 just wasn't keeping my pain level as steady as I would like. He took me off the Morphine and put me on Oxycodone IR (15mg I think) 3 times a day and dropped the Percocets to 3 a day as needed for breakthrough. He mentioned that the Oxycodone IR didn't have any Acetaminophen but that is wasn't the same as Oxycontin. I don't really care one way or another, I just want to know what I am taking. So does anyone know the difference between Oxycodone IR and Oxycontin?
