Researchers used artificial intelligence to analyze more than 400,000 Reddit posts from users of GLP-1 weight-loss medications like Ozempic, identifying frequently reported side effects not commonly highlighted in clinical trials. The analysis revealed unexpected symptoms including menstrual irregularities, chills, and hot flashes that users discussed online. This approach demonstrates how AI-powered analysis of social media data could serve as an early detection system for adverse drug effects that may be underreported in traditional clinical settings.


Social media analysis could complement traditional pharmacovigilance by capturing real-world patient experiences and rare side effects that emerge after drugs reach the market. This method may be particularly valuable for widely-used medications where large-scale post-market monitoring is essential for patient safety.


By analyzing over 400,000 Reddit posts, researchers discovered that users of popular GLP-1 weight-loss drugs frequently discussed unexpected symptoms like menstrual irregularities, chills, and hot flashes. The findings suggest AI could turn social media into a powerful early-warning system for spotting side effects that clinical trials may miss.
