Utility of N-acetylcysteine in Non-Acetaminophen-Induced Liver Injury Secondary to Influenza A Infection

Influenza A, which belongs to the Orthomyxoviridae viral family, is a known causative agent of respiratory illness and systemic inflammation. Annual influenza immunizations are crucial in reducing the incidence and severity of the flu. Intravenous (IV) N-acetylcysteine (NAC) is a pharmaceutical agent indicated for hepatic injury, particularly to address oxidative stress and inflammation secondary to acetaminophen toxicity. The authors present a case of a young female with acute liver injury and impending liver failure in the setting of viral influenza A infection, successfully treated with IV-NAC.
