Abstract

Importance: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have gained use primarily due to their weight-reduction effects, although a regulatory review was undertaken for potential suicidality concern. Objectives: To evaluate potential signals for suicidal and self-injurious adverse drug reactions (ADRs) associated with the GLP-1 RAs semaglutide and liraglutide. Design, Setting, and Participants: Disproportionality analysis through the case-control design using the World Health Organization (WHO) global database of suspected ADRs. Participants were clinical patients worldwide experiencing an ADR suspectedly attributable to semaglutide or liraglutide in the database from inception to August 30, 2023. Data were analyzed from September to December 2023. Exposure: Treatment with semaglutide or liraglutide regardless of indication or treatment duration. Main Outcomes and Measures: Reporting odds ratio (ROR) and the bayesian information component (IC) with 95% CIs were calculated as measures of disproportionate reporting of suicidal and self-injurious ADRs associated with semaglutide and liraglutide compared with all other medications. Sensitivity analyses were conducted including patients with coreported use of antidepressants and benzodiazepines and using dapagliflozin, metformin, and orlistat as comparators. A disproportionality signal was considered when the lower limits of the ROR and IC were above 1 and 0, respectively. Results: A total of 107 (median [IQR] age 48 [40-56] years; 59 female patients [55%]) and 162 (median [IQR] age 47 [38-60] years; 100 female patients [61%]) cases of suicidal and/or self-injurious ADRs were reported between November 2000 and August 2023 with semaglutide and liraglutide, respectively. Significant disproportionality was detected only for semaglutide-associated suicidal ideation (ROR, 1.45; 95% CI, 1.18-1.77; IC, 0.53; 95% CI, 0.19-0.78), which remained significant in patients with coreported use of antidepressants (ROR, 4.45; 95% CI, 2.52-7.86; IC, 1.96; 95% CI, 0.98-2.63) and benzodiazepines (ROR, 4.07; 95% CI, 1.69-9.82; IC, 1.67; 95% CI, 0.11-2.65), when compared with dapagliflozin (ROR, 5.56; 95% CI, 3.23-9.60; IC, 0.70; 95% CI, 0.36-0.95), metformin (ROR, 3.86; 95% CI, 2.91-5.12; IC, 1.20; 95% CI, 0.94-1.53) and orlistat (ROR, 4.24; 95% CI, 2.69-6.69; IC, 0.70; 95% CI, 0.36-0.95). Conclusions and Relevance: This study using the WHO database found a signal of semaglutide-associated suicidal ideation, which warrants urgent clarification.

  • There were no concerns regarding suicide risk or major depressive events across the included trials.

    “Notably, there were no concerns regarding suicide risk or major depressive events across the included trials55,56.”

    From A systematic review and meta-analysis of the efficacy and safety of pharmacological treatments for obesity in adults (2025) · cites this paper as [56]

    The Discussion (page not available) says pooled liraglutide trials identified a potential risk of suicidal ideation, with reports in 0.27% of liraglutide participants versus 0.10% of placebo participants. That contradicts the claim that there were no suicide-risk concerns across the trials. The paper does not establish the claim about major depressive events. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • The WHO's VigiBase identified a notable disproportionality signal for suicidal ideation linked to semaglutide (ROR 1.45; 95% CI 1.18 to 1.77).

    “The WHO’s VigiBase identified a notable disproportionality signal for suicidal ideation linked to semaglutide (reported odds ratio [ROR], 1.45; 95% CI, 1.18 to 1.77), absent for liraglutide, especially in patients concurrently using antidepressants (ROR, 4.45; 95% CI, 2.52 to 7.86) [73].”
  • The VigiBase disproportionality signal for suicidal ideation was absent for liraglutide.

    “The WHO’s VigiBase identified a notable disproportionality signal for suicidal ideation linked to semaglutide (reported odds ratio [ROR], 1.45; 95% CI, 1.18 to 1.77), absent for liraglutide, especially in patients concurrently using antidepressants (ROR, 4.45; 95% CI, 2.52 to 7.86) [73].”
  • In patients concurrently using antidepressants, the VigiBase signal for suicidal ideation linked to semaglutide had an ROR of 4.45 (95% CI 2.52 to 7.86).

    “especially in patients concurrently using antidepressants (ROR, 4.45; 95% CI, 2.52 to 7.86) [73].”
  • The benefits of tirzepatide for OSAS and semaglutide for KOA are largely driven by weight reduction rather than by unique pharmacodynamic properties of each molecule.

    “it is plausible that these effects are largely driven by weight reduction rather than by unique pharmacodynamic properties of each molecule55,56.”

    From A systematic review and meta-analysis of the efficacy and safety of pharmacological treatments for obesity in adults (2025) · cites this paper as [56]

    The Introduction (page not provided) describes weight loss with semaglutide, but does not address benefits for obstructive sleep apnea or knee osteoarthritis. The Discussion concerns suicidality; searches for those conditions, tirzepatide, and weight-loss mediation found no passage assessing whether the claimed benefits arise from weight reduction rather than molecule-specific effects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
