The European Medicines Agency (EMA) recently released a report, following an investigation by its Pharmacovigilance Risk Assessment Committee (PRAC), which found no significant evidence linking GLP-1 receptor agonist drugs to suicidal thoughts or self-harm. This conclusion was based on two large studies of electronic health records that showed no association between the use of GLP-1 medications and an increased risk of suicidal ideation. The Food and Drug Administration (FDA) in the United States also reached a similar conclusion earlier in the year. GLP-1 drugs have been used for the treatment of diabetes for about two decades, but in recent years, they have gained popularity for weight loss as well.

The first study analyzed a database of electronic health records to track the incidence of reported suicidal thoughts among people with diabetes being treated with GLP-1 receptor agonists compared to other non-GLP-1 drugs. The second study, conducted by the EMA, looked at electronic health records to investigate the occurrence of suicidal and self-injury events in people with type 2 diabetes. The PRAC also considered clinical trials, non-clinical studies, and post-marketing surveillance data in reaching its conclusion that no warnings regarding suicidal or self-harm ideation need to be added to the information provided with GLP-1 products.

The concerns about suicide and self-harm with GLP-1 drugs arose from reports by the Icelandic governmental health department in 2023 documenting three patients, two of whom reported suicidal thoughts and one who engaged in self-harm. Despite the small number of incidents relative to the large number of people taking GLP-1 medications, the reports warranted further investigation. Physicians have emphasized the importance of monitoring the mental state of patients using GLP-1 drugs, particularly those who are obese or undergoing obesity treatment, as they may have a higher prevalence of mood disorders.

Research suggests that GLP-1 drugs may actually improve mood in some patients, potentially due to the positive impact of weight loss on self-esteem and the release of certain hormones from fat stores. However, complex relationships with food and emotional attachments to eating may still lead to mood disturbances in some individuals. GLP-1 receptor agonists help promote a sense of fullness after meals and slow down the emptying of the stomach to aid in satiety. Despite their benefits in weight loss and appetite control, GLP-1 drugs should only be used under the supervision of a physician to ensure safety and efficacy.

While GLP-1 medications are generally considered safe when used as directed, there have been rare serious adverse events reported, such as stomach paralysis. People who take GLP-1 drugs often lose significant amounts of weight in a short period of time, prompting concerns about weight regain after discontinuation. Some patients may be prescribed GLP-1 receptor agonists off-label for weight loss, even though only two drugs, Wegovy and Zepbound, are specifically approved for this purpose. Exercise has been shown to complement the effects of GLP-1 drugs for sustainable weight management, but individualized care and monitoring are crucial to ensure the best outcomes for patients.

In conclusion, the recent findings from the European Medicines Agency and the FDA provide reassurance about the safety of GLP-1 receptor agonist drugs in relation to suicidal thoughts and self-harm. While these medications have shown promise in treating diabetes and obesity, their use should be accompanied by careful monitoring and comprehensive care to address individual patient needs and potential risks. Further research may help clarify the relationship between GLP-1 drugs and mood disorders, while ongoing vigilance by healthcare professionals is essential to ensure the well-being of patients using these medications.
