Overview
Oxymorphone is used to manage pain severe enough to require an opioid pain medicine when other pain medicines do not treat pain well enough, or are not tolerated. It is a strong prescription oral pain medicine that contains an opioid (narcotic)
Oxymorphone tablets are used to manage short-term (acute) pain. Oxymorphone extended-release tablets are used to manage severe and persistent pain that requires an extended treatment period with a daily opioid pain medicine.
Oxymorphone can put you at risk for overdose and death . Even if you take your dose correctly as prescribed, you are at risk for opioid addiction, abuse, and misuse that can lead to death.
The FDA requires a Risk Evaluation and Mitigation Strategy (REMS) for opioid analgesics to balance benefits against risks of addiction and misuse. Prescribers must complete REMS-compliant education, counsel patients on safe use and disposal, ensure patients read Medication Guides, and consider patient-prescriber agreements to enhance safety.
Oxymorphone is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. It provides analgesia with no ceiling effect , meaning doses are limited only by adverse effects like respiratory and CNS depression. Its precise analgesic mechanism is unknown, but CNS opioid receptors throughout the brain and spinal cord are believed to be involved.
Oxymorphone first gained FDA approval on April 2, 1959 and is a Schedule II controlled substance.
Oxymorphone is only available as a generic as the brand names Opana, Opana ER and Numorphan have been discontinued.
