From the Guidelines
Antipsychotics like risperidone (Risperdal) and olanzapine (Zyprexa) have a limited role in the treatment of factitious disorder and are not considered first-line therapy for this condition. These medications may be used adjunctively to address specific comorbid symptoms such as severe anxiety, agitation, or psychotic features that sometimes accompany factitious disorder, but they do not treat the core pathology of the disorder itself.
Key Considerations
- When prescribed, careful monitoring for side effects such as metabolic changes, sedation, and extrapyramidal symptoms is necessary, as highlighted in the discussion of atypical antipsychotic agents 1.
- The primary treatment approach for factitious disorder should focus on psychotherapy, particularly cognitive-behavioral therapy and a consistent, non-confrontational therapeutic relationship.
- Antipsychotics should only be considered when there are clear target symptoms that might benefit from these medications, as the underlying psychological mechanisms driving factitious behavior—the need to assume the sick role and receive care—are not responsive to antipsychotic treatment.
Treatment Approach
- The management of factitious disorder is challenging and typically requires a multidisciplinary approach with coordination between mental health providers and other medical specialists to limit iatrogenic harm while addressing psychological needs.
- Given the potential for significant side effects with atypical antipsychotics, such as weight gain and neurological effects 1, their use must be carefully weighed against potential benefits.
Monitoring and Safety
- Regular monitoring of patients on antipsychotics for factitious disorder is crucial, including tracking of side effects and adjustment of medication as necessary to minimize risks while maximizing benefits.
- The guidelines for the use of atypical antipsychotic medications, including the monitoring of blood cell counts for medications like clozapine 1, should be strictly followed to ensure patient safety.
From the Research
Role of Antipsychotics in Factitious Disorder
- Antipsychotics, such as risperidone and olanzapine, are not typically used as a primary treatment for factitious disorder 2, 3, 4, 5.
- However, there is evidence to suggest that antipsychotics may be used as an augmentation treatment for obsessive-compulsive disorder (OCD), which can be a comorbid condition with factitious disorder 6.
- A study found that antipsychotics, including risperidone and olanzapine, showed some efficacy in treating resistant OCD patients 6.
- It is essential to note that factitious disorder is a complex condition, and treatment should be individualized and multidisciplinary, involving psychotherapy and a thorough understanding of the patient's psychological factors 2, 4, 5.
- The use of antipsychotics in factitious disorder should be approached with caution, and more research is needed to fully understand their potential role in treatment 3, 5.
