pain
"I am a chronic pain patient and have tried dozens of medications for my pain. Opana works wonders through an IV when I'm in excruciating pain, but the oral pills just don't help as much. My pain doctor switched me from Oxycodone 4 times a day to Opana 3 times a day and it didn't touch my pain. I did some research and it only absorbs 10% orally. It's good as an IV or injection medication but not as much as an oral pill"
