Public views, patterns, and impacts of social networking site use for medicine-related information in Saudi Arabia: A cross-sectional study

Introduction: Social networking sites (SNSs) are increasingly used as sources of health and medicine-related information, offering accessible communication but raising concerns about misinformation and its impact on medication-related behaviors. This study examined public views, patterns of use, and factors associated with using SNSs for medicine-related information in Saudi Arabia, as well as the perceived impact on medication-related decisions. Methods: A cross-sectional study was conducted among adults aged ≥18 years residing in Saudi Arabia who used at least one SNS. An online self-administered questionnaire was distributed via multiple social media platforms using a secure web-based survey (QuestionPro). Data were analyzed using SPSS version 29. Bivariate and multivariate analyses were conducted, with statistical significance set at p < 0.05. Results: Of 651 participants, 60.2% used SNSs to seek medicine-related information. YouTube was the most commonly used platform, followed by X (formerly Twitter) and Instagram. Commonly searched topics included medication side effects, long-term effects, and mechanisms of action. Nearly one quarter reported altering or discontinuing medications, 25.0% initiated treatments based on SNS information, and 14.5% experienced adverse effects. Higher SNS use was associated with residence outside the Eastern Province, whereas retired participants and those using prescription or over-the-counter medications were less likely to rely on SNSs. Conclusions: SNSs are widely used by the Saudi public for medicine-related information and significantly influence medication-related behaviors. Despite their convenience, these platforms pose risks related to misinformation. Greater involvement of healthcare professionals, particularly pharmacists, is needed to provide evidence-based medication information and enhance medication literacy and patient safety.
