I take Xtamza ER for my chronic pancreatitis pain. It's a long acting oxycodone. The dose is 13.5 mg twice a day. It's fairly effective but I think I'm going to talk to my pain doctor about increasing or changing to something else. Just curious about others luck. I've been dealing with it for 15 years and it is from alcohol abuse. I'm sober now. I don't drink a drop!!! I also take enzyme supplements and I'm on a low fat diet.
