Acute delirious state after epsilon-amino caproic acid administration.

Prior to intravenous pyelography, a patient known to have iodine hypersensitivity was injected intravenously with a bolus of 2 gm epsilon-amino caproic acid (EACA). Immediately following the injection the patient developed an acute episode manifested by a delirious state, with auditory, visual, and kinesthetic hallucinations. The entire episode lasted 8 min, and no residual psychiatric or neurologic symptoms were observed. To the best of our knowledge no such side effect of EACA has been reported so far.
