Tats,
You are correct in your assumption of the
oxycontin dose. If you take a 20 mg oxycontin and break it in half you have 10 mg of
oxycodone. But in doing that you also inactivate the time release action of the pill. So, if you break it in half and take half of it, it is equilavent to taking 10 mg of oxycodone (Percodan,
Percocet). This is an acceptable dose of oxycodone. But remember, if you inactivate the time release by breaking it in half, you will also need to take another dose 4 hours later instead of 8 hours later. I don't know why you are asking this but if the oxycontin is not working for you at the dose the doctor is giving to you, I would see the doctor about a dose adjustment. That is safer than breaking a time-released pill in half. I hope that helped, good luck!
