Hubby has been on Oxycontin for a few years now. It helps a lot but of course he can not take enough to relieve all the pain. Oxycontin is very expensive. I found out from my pharmacist that there is a generic form of morphine called MS Contin (time released) and MSIR (fast acting). He has changed to using this and so far it is working well. My insurance pays 100% on generic so it has helped with the drug bill. Just thought you might like to know!!
