What is the diagnosis for Opioid Intoxication?

A diagnosis of “opioid intoxication” is based on the recent use of an opioid with symptoms listed below. Opioids include heroin, fentanyl, and prescription pain relievers such as oxycodone (OxyContin), hydrocodone (Vicodin), codeine, morphine, and others. 

Symptoms of opioid intoxication include:

• Significant problematic behavioral or psychological changes (e.g., initial euphoria followed by apathy, dysphoria, psychomotor agitation or retardation, impaired judgment) that developed during, or shortly after, opioid use.
• Pupillary constriction and one or more of the following symptoms that developed during, or shortly after, opioid use:
  • Drowsiness or coma
  • Slurred speech
  • Impairment in attention or memory

The symptoms are not attributable to another medication condition or mental disorder, including intoxication with another substance.
