Q

Psychosocial interventions patients with schizophrenia

65
Tardive dyskinesia: 
Delayed; symptoms usually appear after 1 to 2 years of continuous exposure to a dopamine 2 receptor antagonist and almost never before 3 months with an insidious onset, evolving into a full syndrome over days and weeks, followed by symptom stabilization and then a chronic waxing and waning of symptoms.

77
Dystonias
Acute dystonias are involuntary contractions of major muscle groups, and are characterized by symptoms such as torticollis, retrocollis, oculogyric crisis, and opisthotonos. These are usually rapid in onset and highly disturbing to patients. An extremely rare dystonia, laryngospasm, can be life threatening.
78
Treat dystonia
Dystonias that are very disturbing can be treated with 1 to 2 mg of benztropine  or 50 mg of Benadryl daily, administered intravenously or intramuscularly. Milder dystonias can be treated with oral benztropine 1 to 2 mg once or twice daily.
