Hepatitis C treatment and erotomania

The emergence of psychosis during antiviral therapy for hepatitis C is a rare side effect poorly understood in terms of etiopathogenesis, clinical features and prognosis. Erotomania is a rare psychotic syndrome characterized by the presence of a delusion: the patient (usually a female) is loved by a specific man. We present a patient who began a clinical picture of erotomania that involved his doctor a few days after treatment of interferon and ribavirin was started. He stalked his doctor, forcing the police and the court to intervene. Nevertheless, once antipsychotic treatment was established, symptoms remitted, and the patient continued antiviral treatment successfully.
