Further Outpatient Care

Consider referral to a drug rehabilitation program. Repeated use of PCP can result in addiction, and abrupt discontinuation of the drug can produce withdrawal symptoms, including craving, confusion, and depression.


Further Inpatient Care

Any patient with evidence of unrelenting agitation, hypertensive crisis, hyperthermia, seizures, respiratory depression, rhabdomyolysis, or severe traumatic injuries should be admitted to the hospital, and possibly to an intensive care setting if indicated.

Consider a psychiatric evaluation for substance abuse counseling and/or suicidal ideations.



The outcome in cases of PCP toxicity tends to be worse in patients who present with any of the following:

  • Rhabdomyolysis
  • Renal failure
  • Seizures
  • Hyperthermia
  • Hypertensive crisis
  • Traumatic injuries
