Semaglutide, sold under brand names Ozempic and Wegovy, has taken the type 2 diabetes and weight loss world by storm. But its meteoric rise has prompted growing concerns around potentially serious semaglutide side effects, especially regarding mental health. Specifically, questions like does Ozempic cause depression? have emerged.

On August 20, one study set off alarm bells by finding a potential link between semaglutide and increased suicidality. Understandably, this sparked worry across the medical community about the safety of this otherwise game-changing drug. ¹

However, just two weeks later, another study muddled the waters by suggesting semaglutide may not heighten depression or suicidal ideation for those without pre-existing mental illness. ²

So, which is it? This article will dive into both studies, comparing their findings and exploring the ongoing conversation about semaglutide side effects.

Study 1: Initial Concerns About Semaglutide and Suicidality

The first study, published on August 20, 2024, in JAMA Network Open, raised critical concerns regarding semaglutide side effects, particularly concerning its impact on mental health. ¹

Researchers evaluated data from the World Health Organization (WHO) global database and identified a troubling trend: an increased risk of suicidality in patients taking semaglutide. ¹ This finding highlighted a potential mental health risk, raising the question: does Ozempic cause depression?

To answer this, let’s break down the study’s findings:

• Disproportionality signal: The "disproportionality signal" refers to an association between semaglutide use and increased reporting of suicidal ideation. In the initial analysis, this signal was significant, meaning the data suggested that people taking semaglutide were more likely to report suicidal thoughts than those not on the medication.

• Co-reported antidepressants and benzodiazepines: The researchers then looked specifically at cases where people taking semaglutide were also on antidepressants or benzodiazepines (medications often prescribed for anxiety or depression). They found that the disproportionality signal (the increased reporting of suicidal ideation) remained significant in people also taking these medications, particularly with benzodiazepines.

• Excluding antidepressants and benzodiazepines: When the researchers excluded cases where people were taking antidepressants, the disproportionality signal disappeared. This suggests that the increased reporting of suicidal ideation might be related to the co-use of antidepressants. However, when excluding cases where people were on benzodiazepines, the disproportionality signal remained significant. This means that even without benzodiazepines, semaglutide use was still associated with increased suicidal ideation. ¹

These findings suggest a possible interaction between underlying mental health conditions (such as anxiety and depression) and semaglutide side effects. The fact that the disproportionality signal changes depending on whether patients are taking certain psychiatric medications suggests that semaglutide side effects may depend on underlying mental health conditions. ¹

The limitation of this study is that it cannot prove that semaglutide causes depression or suicide risk. The researchers used a broad database that did not have detailed patient profiles. Due to this, the study design did not account for all possible confounding factors, such as the severity of obesity or the presence of other psychiatric conditions.

Study 2: New Evidence and Reassurance

In contrast to the initial findings, a new study published on September 3, 2024, in JAMA Internal Medicine provided a more nuanced understanding of semaglutide side effects. ²

This analysis reviewed data from four clinical trials, which involved over 3,000 participants without major psychiatric disorders. The researchers compared the number of reports of suicidal ideation in groups taking semaglutide 2.4 mg or a placebo. ²

The findings were reassuring: semaglutide did not increase the risk of depression or suicidal ideation among these individuals. Researchers found no clinically meaningful differences in depressive symptoms between those taking semaglutide 2.4 mg and those on a placebo. ²

This study utilized a more targeted approach, focusing on a group of individuals who were otherwise mentally healthy at the start of the trial. By isolating this group, the researchers were able to provide a clearer picture of semaglutide side effects, showing that the increased risk of suicidality observed in the earlier study might be limited to a specific subset of patients with pre-existing vulnerabilities. This finding reassures semaglutide users who do not have a history of mental health issues.

Comparing the Two Studies: Key Differences

The two studies, while seemingly contradictory, complement each other by painting a more detailed picture of semaglutide side effects in different patient populations.

The initial study raised valid concerns, especially for patients with a history of mental health issues. However, the second study refined this concern, showing that for individuals without such a history, the risk of suicidality or depression does not increase with semaglutide use.

The key difference lies in the populations studied. The first study included participants with mental health conditions, ¹ while the second focused on a mentally healthy group. ² This distinction is critical for understanding how semaglutide side effects might impact different segments of the population.

So, does Ozempic cause depression? Well, based on the data we have, it’s hard to establish a solid connection. Additional studies are still needed. However, the second study provides reassurance by showing that in a large population of mentally healthy individuals, the risk of suicidality did not increase with semaglutide use.

Implications for Patients and Healthcare Providers

For most patients, the newest findings provide reassurance that semaglutide is likely safe from a psychiatric standpoint. Individuals with no prior history of depression or other mental health disorders can feel more confident about potential semaglutide side effects.

However, for patients with a known history of depression or anxiety, the initial study's concerning findings suggest a need for caution. Though the initial study had limitations, it highlights the importance of considering mental health history when deciding whether to begin semaglutide.

If you are struggling with any mental health issues, let your doctor know before beginning semaglutide. They can closely track your mood and psychological well-being while you’re taking this medication.

Conclusion

Initial concerns about increased suicidality with semaglutide raised important red flags and highlighted the need for further investigation into semaglutide side effects. However, the latest findings provide much-needed context and reassurance that, for most patients without a history of mental health issues, semaglutide remains a viable and safe option if used under medical supervision.

That said, if you are currently taking semaglutide and experiencing concerning changes in your mood, the question of “Does Ozempic cause depression?” warrants a discussion with your doctor. They can determine whether semaglutide or another factor is impacting your mood. By keeping the lines of communication open, you and your doctor can make the best choice for your well-being.
