Ziprasidone in the treatment of delusional parasitosis.

Delusional parasitosis is characterized by a patient's fixed false belief of being infested with parasites or small creatures. The first-line treatment options are typical antipsychotics such as pimozide. However, the accompanying extrapyramidal side effects might limit their use. We report on a patient with a good response to pimozide combined with ziprasidone. Ziprasidone is an atypical antipsychotic drug with a lower risk of extrapyramidal symptoms; thus, it might be considered a good first or second treatment option for delusional parasitosis.
