January 2026 in “Quality in Sport” This review observed that semaglutide may have therapeutic benefits for skin conditions like psoriasis and hidradenitis suppurativa, but reports of adverse skin reactions exist, indicating the need for further research to understand its safety and efficacy in dermatology.
May 2024 in “Psychiatric News” In this study, analysis of electronic health records suggested that patients taking semaglutide were significantly less likely to experience suicidal ideation compared to those on non-GLP-1 obesity or diabetes medications.

August 2025 This study found that GLP-1 receptor agonists show potential for improving psoriasis and hidradenitis suppurativa by reducing inflammation and lesion severity, but they also pose dermatological risks such as alopecia and injection site reactions.
May 2026 in “Pharmaceuticals” This study analyzed safety data for semaglutide, liraglutide, and tirzepatide from the EudraVigilance database, identifying potential safety signals not listed in current SmPCs, such as optic ischemic neuropathy and pancreatitis, underscoring the importance of ongoing pharmacovigilance.
February 2025 in “medRxiv (Cold Spring Harbor Laboratory)” This study observed an increased risk of alopecia areata among new users of GLP-1 agonists semaglutide and liraglutide compared to users of bupropion-naltrexone, highlighting potential hair loss concerns with these medications.
