The aim of this study is to describe the efficacy and safety of risperidone, in the treatment of delusions of infestation.
Method:
The authors present a three-case series in which risperidone was used to treat delusions of infestation.
Results:
All three patients responded to risperidone and experienced no extrapyramidal side effects. Two of our patients had failed treatment with haloperidol and another had failed treatment with pimozide.
Conclusions:
Risperidone was an effective and safe treatment in three cases of delusions of infestation. It is possible that 5-HT2 antagonism is essential for therapeutic benefit in this condition.
