Quality and reliability of semaglutide content on different Chinese short video platforms: a study focusing on side effects

The quality and reliability of semaglutide-related short videos are significantly influenced by platform ecology. Publicly accessible drug information on short-video platforms often lacks clear differentiation between approved indications and dosage regimens, contributing to generalized interpretations of drug risks. The drug information accessible to the public exhibits structural biases, with side effect narratives demonstrating a clear "platformization" pattern. The dual-perspective analysis revealed that inter-platform differences in the portrayal of specific adverse events (e.g., gastrointestinal and hepatobiliary effects) were more discernible in the side effect-focused subsample. Future interventions should be tailored to platform-specific features to enhance the completeness and scientific rigor of online pharmaceutical information.
