"i have been on oxycontin for 8 years now, i have many problems and i am disabled. they&#039;ve tried me on several medicines before this and nothing worked. i am so sensitive and allergic to a lot of medicines. but then they started me on oxycontin&#039;s and it has worked for me up until last month when they changed them. they are not as effective as they once were and now i am suffering because of it.
