How long should someone be on oxycotine? My husband has been on it for several years and I'm trying to convince him to go to a pain specialist. He was on Roxecete at first then went to morphine pills, and he's been on oxyctine for about 5 years his injury was eight years ago. What are the long term affects? I have noticed something going on with his teeth, is that a side affect? Please if anyone could give me information that might persuade him to come off the stuff.
