How is Opana different from Opana ER?

The pain medication Opana (oxymorphone) treats short-term pain such as what you might experience after surgery. Each dose lasts four to six hours.

Opana ER is an extended-release form of the drug designed to treat continuous pain that's expected to last for a long period of time, such as chronic back pain or pain caused by cancer. Each dose lasts 12 hours. Make sure you follow the directions for the specific pill you are taking. Unlike Opana, Opana ER is more potent and can be dangerous to use if you don't follow your doctor's instructions carefully. Never crush or chew Opana ER; this could cause too much of the drug to be released into your body and cause a fatal overdose.
