Purpose: FDA regulations state print ads for prescription drugs must provide a true statement of information "in brief summary" describing "side effects, contraindications and effectiveness." To fulfill these requirements, these ads typically display risk information both as important safety information (ISI) on the "main" ad page with the product claims and on a separate "brief summary" page. The ISI can be lengthy and may repeat brief summary content.
Methods: The authors tested two versions of the ISI (short versus long) and the presence or absence of a brief summary in direct-to-consumer prescription drug print ads for two medical conditions: overactive bladder (N = 181) and rheumatoid arthritis (N = 179). Attention was measured with eye-tracking and self-report methods. Risk retention and perceptions were self-reported.
Results: Participants spent more time viewing ads with a long ISI or a brief summary and in some instances, recalled more risks. The combination of a long ISI and a brief summary did not increase or decrease attention to or retention of risk information.
Conclusion: A long ISI and a brief summary may perform similar functions.
