Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) like Semaglutide and Liraglutide have become popular, particularly for their weight loss benefits in addition to managing type 2 diabetes. However, recent findings from a JAMA Open Network study have raised concerns about a potential link between these drugs and increased reports of suicidal ideation. This article delves into the study’s findings, explores the potential risks, and underscores the need for further investigation.
The Rising Popularity of GLP-1 Receptor Agonists
GLP-1 RAs, including semaglutide and liraglutide, were initially developed for treating type 2 diabetes. Their ability to aid in weight loss quickly gained attention, leading to widespread use beyond diabetes management. Today, millions of people use these medications, either as prescribed by healthcare professionals or, in some cases, off-label for weight loss. Despite their growing popularity, concerns have emerged about the safety of these drugs, particularly regarding their potential impact on mental health.
Linking GLP-1 RAs to Suicidal Ideation
A recent disproportionality analysis conducted by JAMA Open Network researchers using the WHO global database of suspected adverse drug reactions (ADRs) sought to evaluate the association between GLP-1 RAs and suicidal tendencies. The study analyzed data from clinical patients worldwide who experienced ADRs potentially linked to semaglutide or liraglutide, spanning from the inception of the database to August 2023.
Key Findings:
- Suicidal Ideation and Semaglutide: The study identified a significant disproportionality signal of suicidal ideation associated with semaglutide. This signal remained significant even when compared to other diabetes medications like dapagliflozin and metformin, as well as in patients who were also taking antidepressants or benzodiazepines.
- Liraglutide’s Impact: While liraglutide was also associated with reports of suicidal ideation, the disproportionality signal was not as pronounced as with semaglutide.
The Numbers Behind the Concern
The study reported a total of 107 cases of suicidal and/or self-injurious ADRs linked to semaglutide and 162 cases linked to liraglutide. The majority of these cases involved suicidal ideation, with some cases resulting in suicide attempts and, tragically, fatalities. For semaglutide, the reporting odds ratio (ROR) for suicidal ideation was 1.45, indicating a higher likelihood of these ADRs occurring with semaglutide compared to other medications.
Disproportionality Analysis
Disproportionality analysis is a method used to identify signals of potential drug safety issues by comparing the frequency of specific ADRs with a particular drug to the frequency of those ADRs with other drugs. In this study, the ROR and the Bayesian information component (IC) were calculated, with the lower limits of the ROR and IC being above 1 and 0, respectively, to indicate a significant signal.
The Role of Antidepressants and Benzodiazepines
Interestingly, the study found that the risk of suicidal ideation associated with semaglutide was higher in patients who were also taking antidepressants or benzodiazepines. This finding suggests a potential interaction between these medications and GLP-1 RAs, warranting closer monitoring of patients who are prescribed these drugs concurrently.
Help is out there
- 911 is the national emergency number in the United States.
- The 988 Suicide & Crisis Lifeline (https://988lifeline.org/) is a 24-hour, toll-free, confidential suicide prevention hotline available to anyone in suicidal crisis or emotional distress.It provides Spanish-speaking counselors, as well as options for deaf and hard of hearing individuals. It is only available in the United States. A 24-hour online chat service is also available.
- The 988 Suicide & Crisis Lifeline can be reached at 988.
- The Lifeline’s previous number, 1–800–273–8255, can still be dialed at anytime.

- Deaf or Hard of Hearing: Use your preferred relay service or dial 711 then 988.
Regulatory Responses and Ongoing Investigations
In light of these findings, regulatory authorities, including the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA), have initiated investigations into the potential link between GLP-1 RAs and suicidal tendencies. Although these agencies have not yet found conclusive evidence to establish a direct relationship, the ongoing review highlights the importance of caution when prescribing these medications, particularly to patients with a history of mental health issues.
The Need for Further Research
The study’s findings underscore the need for urgent clarification regarding the potential risks associated with GLP-1 RAs, particularly semaglutide. Given the widespread use of these medications, further research is essential to fully understand the mechanisms underlying the reported increase in suicidal ideation and to develop appropriate guidelines for healthcare providers.
While GLP-1 RAs like semaglutide and liraglutide offer significant benefits for weight loss and diabetes management, the potential link to increased suicidal ideation cannot be overlooked. Patients and healthcare providers must remain vigilant, particularly when these drugs are prescribed alongside antidepressants or benzodiazepines. As regulatory agencies continue to investigate, it is crucial to prioritize patient safety and ensure that these medications are used responsibly.
