A diagnosis of phencyclidine (PCP) intoxication is based on the recent use of phencyclidine (or a pharmacologically similar substance) that causes:
- Significant problematic behavioral changes (e.g., belligerence, assaultiveness, impulsiveness, unpredictability, psychomotor agitation, impaired judgment)
- Within 1 hour, two or more of the following symptoms:
- Rapid eye movements
- Hypertension or rapid heartbeat
- Numbness or less responsiveness to pain
- Stumbling, falling down, incoordination
- Slurred speech
- Muscle rigidity
- Seizures or coma
- Hearing sensitivity
The symptoms are not attributable to another medical condition or mental disorder, including intoxication with another substance.
