PCP Withdrawal: Symptoms, Depression, Craving and Treatment
PCP withdrawal can involve craving, depression, anxiety, sleep and appetite changes, headache and sweating. Learn what is known about the timeline, serious warning signs and treatment.
PCP (Phencyclidine)
PCP is phencyclidine, an illicit dissociative drug that can cause numbness, altered perception, severe agitation, psychosis, seizures and dangerous medical toxicity. These guides cover the drug from first-use questions through addiction treatment and emergency risks.
PCP is a dissociative drug with a clinical profile that is very different from cocaine, opioids or LSD. It can produce numbness, abnormal eye movements, severe agitation, psychosis, high blood pressure, seizures and coma. Repeated use can become compulsive even though PCP does not usually produce the same medically dangerous withdrawal syndrome seen with alcohol or benzodiazepines.
Use the guides below to understand the drug, distinguish intoxication from withdrawal, interpret testing, compare PCP with ketamine and identify when psychiatric or medical symptoms require emergency care.
