Pimozide: use in dermatology

Pimozide is widely used in psychiatry for chronic psychoses, schizophrenia, the syndrome of Gilles de la Tourette and to a certain extent, also in dermatology. The only dermatological indication is for delusions of parasitosis. Though there is a good rationale for using pimozide in this disease, the majority of the studies on pimozide in dermatology are uncontrolled trials and case reports.
