Oxymorphone, sold under the brand names Opana among others, is a opioid pain medication. Pain relief after injection begins after about 5–10 minutes and 15–30 minutes after rectal administration, and lasts about 3–4 hours for immediate-release tablets and 12 hours for extended-release tablets.
Oxymorphone extended-release is used to help relieve severe ongoing pain. It belongs to a class of drugs known as long-acting opioid (narcotic) analgesics. It works in the brain to change how your body feels and responds to pain.
Do not use the extended-release form of oxymorphone to relieve pain that is mild or that will go away in a few days. This medication is not for occasional (“as needed”) use.
