A recent observational study published in JAMA Network Open has revealed that users of semaglutide, marketed as Ozempic and Wegovy, may experience suicidal thoughts at a rate 45% higher than those on other medications.

The study, which analyzed data from the World Health Organization's adverse drug reaction database, found a significant association between semaglutide and suicidal ideation, particularly among patients also using antidepressants and benzodiazepines.

Specifically, the reporting odds ratio for suicidal ideation was 1.45 for semaglutide, with even higher odds ratios of 4.45 and 4.07 for those on antidepressants and benzodiazepines, respectively.

However, experts have raised concerns about the study's methodology, noting limitations such as the lack of control for variables like patient adherence and medical history.

Despite these methodological concerns, researchers stress the urgent need for clarification regarding the mental health risks associated with semaglutide.

Some experts suggest that the findings may reflect the psychological impacts of weight loss rather than a direct side effect of the medication itself.

Outside experts have characterized the study's evidence of a causal link between semaglutide and suicidality as weak, emphasizing the need for further investigation.

Regulatory authorities, including the FDA and the European Medicines Agency, are currently reviewing the safety profiles of semaglutide and liraglutide, particularly concerning mental health risks.

Healthcare providers are advised to closely monitor patients with prior mental health issues while on semaglutide and to assess their psychiatric history before treatment.

The findings have prompted calls for further investigation into the potential risks of semaglutide, especially given the increasing use of GLP-1 receptor agonists among younger individuals.

Interestingly, despite the reported increased risk of suicidal thoughts, patients on semaglutide showed a lower rate of suicidal behaviors compared to those on other medications.

The study's researchers acknowledged their inability to infer causality from the data, highlighting the complexity of the relationship between semaglutide and mental health outcomes.
