... take it for breakthrough pain but i need something thats a little stronger and that last longer like a extended release than i would be able to function a little better.My hip last night felt like the bone was cutting through the skin.It was aweful.I take morphine 2 times a day 15 mg time release i was on 30 mg time release but it was to strong and i could function so i asked my doctor to reduce it to 15mg I am suppose to take the Oxycodone for breakthrough pain but i have found if i take it with the morphine together it works much better.Any suggestions?Is oxycotin time release and if so what would be a dosage equal to maybe 10/500 of the oxycodone?anyone know?I would like to be knowledgeable when i see the doctor
