"i came to this site to see if i was only person who had some minor issues with this medication. i started opana er 10mg 4 days ago. i was to start it 9 days ago but my insurance initially wasn&#039;t going to cover the cost. my doctor filled out some forms and i am preapproved for a year. i find that the medicine is great for my pain but it does not last 12 hours, i have found that at 8 to 9 hours later i need another one. if prescribed 3&#039;s daily it would be a perfect medication and who knows maybe i wouldn&#039;t need my breakthrough medicine."
