The purpose of the present study was to compare experts' vs non-experts' viewpoints on the label information and attitudes toward risks of OTC drugs. An eye-tracking experiment and a questionnaire survey were performed. In the eye-tracking experiment, the viewing durations for 12 items of labeling information were analyzed. The results from the eye-tracking experiment showed that experts viewed "ingredients", "warning", and "purpose" longer than non-experts. In addition, the questionnaire survey indicated that experts evaluated risks of OTC drugs more highly than non-experts. Because the risks of OTC drugs were evaluated highly by experts, labels of OTC drugs with emphasis of risks may assist better communication between experts and non-experts.
