OxyContin - how long does it actually last when swallowing whole?

[Supeudol]

Purdue claims it lasts 12 hours when swallowing whole. But I have heard anywhere from 6-10 hours or so.

Also, my other question is how much Oxycodone is released within the first hour or so? Let's just say I swallowed a 40mg OxyContin pill.

I have never really swallowed OxyContin whole. Always been chewed or crushed and snorted. But as I just got a prescription for about 12 OxyContin 40's to taper down and get off. These questions come to mind.

Thanks very much.

From past experience I'd guess 10 hours at least. Like you I always chew them and get a good 5 hour buzz. OC is not plentiful in my area, so I have only a basic opiate tolerance. Good luck.

Lasts roughly 8 hours for me, I'm prescribed it 80mg 3 times a day. The pill releases 30-40% of the dose right away and the rest, in a perfect world, over "12 hours". So of your 40mg you're getting around 15mg right away, give or take.
