The doctors are so regulated and watched when they write for opiates that prescript
ion writing may change with the last seminar, email, or chat with a colleague. I am a retired (by disability) psychologist. Oxycontin is such a superior medicine to all the other serious pain relievers that force you to take acetominephen along with them.
I avoided oxycontin just because of all this press about
abuse, but I have found that time release opiates are far preferable to the immediate high and progressively lower and lower effect of Percocet (which I still take for breakthrough pain).
My doc gives me 10mg which I break in half to make Percocet 5mg with half the acetominephen. He writes it for half the dose and I can take it 3 times a day. My pain varies. If I spend a few hours shopping, which means standing for long periods (two hours) I will need all three.
I also get facet injections in my spine for low back and neck pain every 6 months, but that does not dull the grinding bone pain in my right hip from a boating accident in which I shredded the cartiledge.
Definitely ask your doc these things. I am sure your doc will be willing to explain the difference in prescript
ion to you.
And oxycontin is a great medication. It gives you a lot of freedom.
