title: Atypical antipsychotic drugs in the treatment of delusional parasitosis.
abstract: BACKGROUND
  Delusional parasitosis (DP) is a rare delusional disorder in which patients believe that they are infected with parasites, worms, insects, or bacteria. Antipsychotics are the preferred treatment in these patients.
  
  
  METHODS
  Case series in which we summarize six patients with DP treated with atypical antipsychotic medications including amisulpride, olanzapine, and risperidone.
  
  
  RESULTS
  One patient had a myocardial infarction after being given amisulpride, and several patients did not adjust well. Parenterally administered antipsychotics, particularly risperidone, were the most effective treatment in this series of patients with DP.
  
  
  CONCLUSIONS
  Patients with DP can be difficult to treat; however, parenterally administered antipsychotics appear to produce better results in these patients.
