Central nervous system toxicity of H2-receptor antagonists has rarely been confirmed by the respective elevated cerebrospinal fluid drug concentrations. We observed two hemodialyzed neurosurgical patients in whom mental deterioration and convulsions developed after intravenous famotidine therapy (10 and 40 mg/day).
