I just got my wisdom teeth removed and the doctor gave me Oxycodone to relieve that pain. The only difference in Oxycodone and Oxycontin is the release rate. Oxycodone (Percocet) is released farily quickly and has a half life of only 3-4 hours. Oxycontin on the other hand is extended release over a period of around 12-24 hours.
To be honest, It didn't do shit for me. I got to the point where I was taking 4 of those things at once because they weren't effective at 1 tab as prescribed. I don't think the drug is as powerful as some may think. It barely makes your pain tolerable. Morphine and Dilaudid are MUCH stronger and more effective.
