"I was prescribed OxyContin 30 mg 4 X daily and eventually it didn't work so well as when I first started taking it. I took my left over OxyContin pills to my physician who then prescribed me 40 mg Opana ER (yellow octagonal shape). It works so much better than OxyContin and the pain relief lasts longer. There is no "high" associated with Opana ER. I have several painful medical conditions after being injured at work and some years later was involved in a near fatal car wreck. Opana ER is a wonderful medication. The only drawback is that is does take about an hour to start working well. The pain relief lasts about 8 hours. I highly recommend speaking to your physician about Opana ER if continuous pain relief is needed."
