Cimetidine hepatitis.

This case of an adult with cimetidine-induced hepatitis is presented. An etiologic role for the drug was strongly suggested when the patient developed transient hepatic dysfunction after two reexposures to cimetidine, which reverted promptly on withdrawal of the drug. The temporal relation between the administration of the drug and the development of hepatic dysfunction suggests that it is a hypersensitivity type of reaction.
