Abstract

Delusional parasitosis is a rare psychiatric disorder characterized by the persistent belief of infestation by parasites, despite the absence of medical evidence. This case series describes four patients with delusional parasitosis who were successfully treated with olanzapine. The patients showed a significant improvement in symptoms with no adverse effects. The effective use of olanzapine in these cases suggests that it could be a useful first-line treatment option for patients with delusional parasitosis.
