Opana (oxymorphone) is a Schedule II opioid with a risk of abuse, addiction and dependence. Even when used as directed, side effects include nausea, fever and fatigue.

Article at a Glance:

  • Oxymorphone is a narcotic that is sold under the brand name Opana.
  • A brand-name long-acting form of oxymorphone, Opana ER, was discontinued by the manufacturer. However, a generic form of long-acting oxymorphone is still available.
  • Oxymorphone is a Schedule II controlled substance.
  • Oxymorphone carries many of the same risks and side effects as other opioids, including the risks of abuse, addiction and dependence.

Opana (Oxymorphone) Side Effects

As a Schedule II controlled substance, three of the primary side effects of oxymorphone misuse are addiction, dependence and tolerance. Although similar, these terms refer to different risks of Opana.

  • Addiction is a disease of the brain that also affects physical health and the entire life of the affected person. When a person is addicted to a drug, they keep taking it despite negative consequences.
  • Dependence is a scenario where someone is physically dependent on the presence of oxymorphone, and if they stop using it suddenly, they experience withdrawal symptoms. A person can be dependent on Opana without being addicted.
  • Tolerance is when a person needs higher and higher doses of the drug to get the same results as before.

Other side effects of oxymorphone include:

  • Nausea and vomiting
  • Constipation
  • Pyrexia (fever)
  • Fatigue
  • Itchy skin
  • Headache
  • Dizziness
  • Confusion

Opana “High” Feeling

Opana is frequently abused by people who want to get high. Opana is different from other opioids: although all opioids impact the mu-opioid receptor for pain relief, Opana can also impact other opioid receptors in the brain at higher doses.

Overdose Risk

Opana carries a serious overdose risk. This is especially true when mixed with other central nervous system depressants like alcohol. Opana’s overdose symptoms include:

  • Severely slowed breathing
  • Unresponsiveness
  • Flaccid muscles
  • Cold or clammy skin
  • Small pupils
  • Low blood pressure
  • Slow heart rate

If you believe someone is experiencing an overdose, give naloxone (Narcan) and dial 911. If you are unsure what the person has taken, you can also call the National Poison Control Center at 1-800-222-1222.

Long-Term Effects of Opana ER (Oxymorphone) Abuse

Whether long or short-acting, chronic opioid use can cause serious side effects, such as:

  • Constipation
  • Breathing problems while sleeping
  • Bone fractures
  • Hormone problems
  • Overdose

Long-acting oxymorphone is currently available as a generic drug only. Until 2018, it was available in an abuse-deterrent form called Opana ER. However, the FDA pulled the drug because there were outbreaks of disease among people trying to inject it. These disease outbreaks included:

  • Human immunodeficiency virus (HIV)
  • Hepatitis C
  • Thrombotic microangiopathy

Common Signs of Opana (Oxymorphone) Abuse
