I can tell you what the blue pill (roxicodone) is about but I cant help you with the avinza. Roxicodone 30mg tabs are instant release oxycodone. They are pretty strong, I take 4 a day with my oxycontin for BT pain and they work great! Hope this helps. JoJo
Avinza is a LA formulation of morphine. It's supposed to last 24 hours but that was not my experience. I was on it for a short time and did not like it and would not return to it.
