Psychiatric Symptoms in a Patient with Influenza A (H1NI) Treated with Oseltamivir (Tamiflu): A Case Report

Abstract

Oseltamivir is the most common antiviral drug used to treat and prevent influenza, Epidemiological studies performed in Japan, the United States, and the United Kingdom indicate that oseltamivir may cause psychiatric symptoms; however, the underlying mechanism has not been elucidated, In South Korea, interest in oseltamivir has increased with the spread of the new influenza virus; however, no case report or investigation of psychiatric symptoms associated with the drug has been reported to date. Here, we report a case of a 22 year old male who complained of mood swings, suicidal feelings, auditory hallucinations, memory deterioration, and insomnia after taking oseltamivir.
