Opana (oxymorphone) is an opioid pain medication. An opioid is sometimes called a narcotic.
Opana is used to treat moderate to severe pain.
The extended-release form of this medicine is for around-the-clock treatment of severe pain. Opana ER is not for use on an as-needed basis for pain.
Opana may also be used for purposes not listed in this medication guide.
You should not use Opana if you have severe asthma or breathing problems, a blockage in your stomach or intestines, or moderate to severe liver disease.
Opana can slow or stop your breathing, especially when you start using this medicine or whenever your dose is changed. Never take this medicine in larger amounts, or for longer than prescribed. Do not crush, break, or open an extended-release pill (Opana ER). Swallow it whole to avoid exposure to a potentially fatal dose.
Oxymorphone may be habit-forming, even at regular doses. Take this medicine exactly as prescribed by your doctor. Never share the medicine with another person. MISUSE OF NARCOTIC PAIN MEDICATION CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
