Management of Acute Psychosis

The optimal management of acute psychosis requires prompt initiation of atypical antipsychotics as first-line treatment, with medication selection based on side-effect profiles and patient characteristics, alongside comprehensive psychosocial interventions. 1

Initial Assessment and Intervention

Rule Out Secondary Causes

  • Evaluate for medical conditions that can present with psychotic symptoms:
    • Endocrine disorders
    • Autoimmune diseases
    • Neurological disorders
    • Infections
    • Drug intoxication or withdrawal
    • Metabolic disorders
    • Nutritional deficiencies 2, 1

Medication Management

First-Line Treatment

  • Atypical antipsychotics are preferred over typical antipsychotics due to better tolerability and fewer extrapyramidal side effects 1
  • Initial target doses for adults:
    • Risperidone: 2 mg/day
    • Olanzapine: 7.5-10.0 mg/day 1

For Acutely Agitated Patients

  • Immediate intervention options:
    • Benzodiazepines (lorazepam or midazolam)
    • Conventional antipsychotics (haloperidol) 1
  • For cooperative but agitated patients:
    • Combination of oral benzodiazepine (lorazepam) and oral antipsychotic (risperidone) 1

Important Medication Considerations

  • Allow 4-6 weeks at therapeutic doses before determining efficacy 1
  • Avoid large initial doses as they don't hasten recovery but increase side effects 1
  • Monitor for serious side effects:
    • Neuroleptic Malignant Syndrome (hyperpyrexia, muscle rigidity, altered mental status) 3, 4
    • Tardive dyskinesia (irreversible, involuntary movements) 3
    • Metabolic changes (hyperglycemia, dyslipidemia, weight gain) 3, 4
    • Cerebrovascular adverse events in elderly patients 3, 4

Psychosocial Interventions

Family Support

  • Progressively inform and educate families about:
    • Nature of the psychotic disorder
    • Treatment approaches
    • Expected outcomes 2, 1
  • Provide emotional support and practical advice 2, 1
  • Develop a supportive crisis plan with the family 1
  • Consider multi-family groups with psychoeducation focus 2

Therapeutic Approaches

  • Implement supportive psychotherapy with active problem-solving orientation 2, 1
  • Focus on finding meaning and developing mastery of the psychotic experience 2, 1
  • Facilitate occupational pursuits, including employment and education 2, 1
  • Address comorbidities:
    • Depression
    • Suicide risk
    • Substance misuse
    • Social anxiety 2, 1

Monitoring and Treatment Adjustment

Regular Monitoring

  • Daily assessment of:
    • Sedation
    • Extrapyramidal symptoms
    • Behavioral changes 1
  • Weekly assessment of:
    • Clinical improvement
    • Side effects 1
  • Discuss early warning signs of relapse with patient and family 2

Treatment Adjustment

  • If significant positive symptoms persist after 4 weeks of therapeutic dosing with good adherence, switch to an alternative antipsychotic with a different pharmacodynamic profile 1
  • Consider clozapine if schizophrenia diagnosis is confirmed and positive symptoms remain significant after two adequate antipsychotic trials (including at least one atypical agent) 1
  • Once psychosis has achieved sustained remission, slow reduction of antipsychotic medication should be tried to determine minimal effective dose 2
  • Long-term medication is advisable for individuals who experience frequent relapses 2

Common Pitfalls to Avoid

  • Missing secondary causes of psychosis - Always rule out medical conditions before attributing to primary psychiatric disorder 2, 1
  • Premature discontinuation - Approximately 65% of patients relapse within 1 year without antipsychotics compared to 30% on medication 1
  • Inadequate trial duration - Full 4-6 week trial at therapeutic doses is necessary before determining efficacy 1
  • Excessive initial dosing - Large doses during early treatment generally don't hasten recovery but increase side effects 1
  • Neglecting family involvement - Families need ongoing support and information in a partnership that involves the patient, family members, and treating clinicians 2
  • Failing to monitor for metabolic changes - Regular monitoring for weight gain, hyperglycemia, and dyslipidemia is essential 3, 4

By following this comprehensive approach to managing acute psychosis, clinicians can effectively address both immediate symptoms and long-term recovery, while minimizing risks and complications.
