Hepatitis associated with amoxicillin/clavulanic acid and/or ciprofloxacin.

We describe an elderly patient with normal pre-existing liver functions who was treated with amoxicillin/clavulanic acid and later ciprofloxacin for acute bronchitis. He developed a pattern of liver dysfunction consistent with hepatocellular injury, with clinical features of a hypersensitivity reaction, which may be attributable to either or both of the antimicrobial agents used. This gradually resolved over a 4-week time period, with conservative management. A review of the relevant literature on drug-induced hepatotoxicity is also presented.
