I have been taking between 4-8 oxycodone 5mg pills on and off for almost a year to ease my back pain and sciatica. About a month ago I noticed they started being less effective and at times leaving me in tremendous pain.
I have been given a Rx for Oxycontin, the ER version 2x a day. The doctor said to start at two 20mg pills each day but I might need to go up to 40mg 2x per day.
How do you compare the two? is 8 x 5 mg (40mg) the same as 2x20 mg ER or is not really apples to apples?
