Opana is a prescription opioid pain-reliever containing the active ingredient oxymorphone. Oxymorphone is a semi-synthetic opioid agonist, meaning it binds to the opioid receptors in your brain to elicit its effects. You may have heard Opana referred to by numerous street names such as ‘The O Bomb,’ ‘Blue Heaven,’ and ‘Mrs. O.’
Opana is available as an immediate-release tablet in either 5 or 10 mg doses. It is also available in an extended-release form (Opana ER). Opana ER is meant for individuals dealing with chronic and severe pain who are in need of continuous pain management, and is not to be taken on an as-needed basis. The highest available dose of Opana ER is the 40 mg tablet (Opana 40).
