Semaglutide (SEM) is the most popularly searched GLP-1 receptor agonist for weight loss, yet it exhibits the lowest proportion of severe adverse drug reactions (ADRs) compared to other GLP-1 RAs, despite having the highest absolute number of spontaneous safety reports.

Semaglutide is the most searched GLP-1 for weight loss, leading to high prescription volumes and consequently the highest number of adverse event reports. However, data shows it actually has the lowest rate of severe adverse reactions compared to other GLP-1 drugs. The high volume of reports is likely due to its popularity and off-label use driven by social media, rather than inherent high severity. Users should be aware that off-label use increases risks like overdose and should be monitored by a healthcare professional.
