Abstract
From questionnaire data obtained from 5412 general pediatric outpatients, the following observations about adverse drug reaction and drug-hypersensitivity were made: (1) About 9.46% of participating children had experienced adverse drug reactions in the past and 3.75% had experienced symptoms of drug-hypersensitivity. Allergic subjects has a higher prevalence of drug-hypersensitivity. (2) Symptoms of drug-hypersensitivity occurred even in young infants. (3) In drug-hypersensitive children, antibiotics were the most frequent cause. (4) Most parents of drug-hypersensitive children didn't know names of drugs resonsible for drug hypersensitivity symptoms in their children, hadn't obtained an accurate diagnosis of drug allergy or drug eruption from their doctors and were unaware of appropriate drug-hypersensitivity prevention.
