Jaundice associated with naproxen.

Hepatic injury in association with naproxen therapy is described and documented by liver biopsy in one patient. Histological findings were consistent with a drug-induced hepatitis, and cessation of therapy led to reversal of the clinical and biochemical changes. Circumstantial evidence is in favour of a hypersensitivity response to the drug rather than direct hepatotoxicity. Increased awareness of clinicians of this probably rare side effect of naproxen may help prompt identification of similar cases.
