op 80 length of action orally?


Searched and googled with no results. Pretty simple question, how long are the ops designed to last? Say i ate an 80, is it meant for 12/18/24 hour pain relief?

Designed for 12-14 hours, but that varies depending on body chemistry, stomach contents/chemistry, etc.


awesome, exactly what i was looking for. Ate two IR 30s last night and i was shocked how hard they hit me, think I’m going to invest in an op 80 for the day/night


I was going to send this to basic drug discussion but I think it’s been covered – they are intended to be dosed twice daily to maintain stable plasma levels in people with chronic pain. Sometimes they don’t last quite that long and people dose them every 8 hours.

If you think this should be reopened (and moved to BDD) feel free to PM me or another moderator.
