Nafcillin-associated hepatotoxicity. Report of a case and review of the literature

Abstract

Nafcillin is a semisynthetic penicillin that is generally well tolerated with few side effects. Hepatic complications are rare but have a potential for serious liver dysfunction. This unusual complication causes a predominantly cholestatic injury, which can persist for prolonged periods even after discontinuing the medication. The pathophysiology may include direct cytotoxicity or an immune-mediate hypersensitivity. Treatment is generally supportive, except for severely symptomatic patients who may require steroids. We report a case of nafcillin-associated hepatotoxicity and review the literature of this disorder.
