Risk of Suicide, Hair Loss, and Aspiration with GLP1-Receptor Agonists and Other Diabetic Agents: A Real-World Pharmacovigilance Study.
Cardiovasc Drugs Ther · 2025
Last updated 2026-05-28A study using four large drug safety databases found no clear evidence linking GLP-1 drugs to increased risks of suicide, hair loss, or aspiration compared to other diabetes medications. However, the drugs semaglutide and liraglutide showed lower reported rates of suicidal events than some alternatives, while GLP-1 drugs were the most reported class for hair loss. Aspiration events were less commonly linked to GLP-1 drugs than to another class called DPP4 inhibitors.

Abstract
PURPOSE: With the increasing popularity of glucagon-like peptide 1 receptor agonists (GLP1-RAs), numerous safety concerns arose pertaining to suicide, hair loss, and aspiration risks. We attempted to validate these concerns.
METHODS: We queried four pharmacovigilance databases to compare GLP1-RAs to sodium-glucose transporter 2 inhibitors (SGLT2is) with respect to these adverse events (AE): the FDA Adverse Event Reporting System (FAERS), the Australian Database of Adverse Event Notifications (DAEN), the European Medicines Agency's (EudraVigilance), and the World Health Organization-Vigibase. OpenVigil 2.1 was utilized to perform a disproportionality analysis for GLP1-RAs, SGLT2is, dipeptidyl peptidase 4 inhibitors (DPP4is), sulfonylureas, metformin, and insulin. The following indices were extracted from the FAERS database from Q4/2003 until Q3/2023: relative reporting ratio (RRR), proportional reporting ratio (PRR), reporting odds ratio (ROR), and chi-squared (χ). A positive signal was detected if PRR > 2 and χ > 4 for any drug-event pair.
RESULTS: No positive signals were observed between GLP1-RAs and either suicide, hair loss, or aspiration risks. Semaglutide [ROR = 0.60 (0.51-0.71)] and liraglutide [ROR = 0.28 (0.23-0.35)] had higher suicidal events than DPP4is and SGLT2is. GLP1-RAs were the most reported class with hair loss [ROR = 0.61 (0.60-0.64)], and semaglutide, liraglutide, and dulaglutide were the three leading medications. GLP1-RAs ranked lower with aspiration events, which were led by sitagliptin and DPP4is as a group.
CONCLUSION: GLP1-RAs exhibit higher reporting of suicide, hair loss, and aspiration events when compared to several other antidiabetic medications despite not meeting the criteria for positive signals yet. This warrants intensive monitoring and reporting.
