Discussions that mention morphine

I think MS Contin is just as safe as Avinza considering they are both morphine sulfate. I think the only difference is that the Avinza is long acting and therefor you only have to take it once a day. With the MS Contin you need to take it several times a day. If you can tolerate the Avinza and it is working well for you then the MS Contin should do the same thing as long as you are on the appropriate dose.
