title: [Late adverse reactions of non-ionic intravenous contrast media].
abstract: A prospective study of late adverse reactions of non-ionic intravenous contrast media was performed. Information was collected from questionnaires returned by the patients, and also from further interviews. The incidence of adverse reactions was 8.3% in all patients, and was higher in female (11.1%) than male (5.8%). They were more frequent in the patients with age ranging from 20 to 49 than those older than 50. The most frequent symptom was headache, followed by itching, skin rashes, nausea, dizziness, and general fatigue. More than half of the reactions occurred within six hours after injection, but reactions a few days later were also reported.
