Is There a Risk for Semaglutide Misuse? Focus on the Food and Drug Administration’s FDA Adverse Events Reporting System (FAERS) Pharmacovigilance Dataset
Open accessAbstract
Recent media reports commented about a possible issue of the misuse of antidiabetics related to molecules promoted as a weight-loss treatment in non-obese people. We evaluated here available pharmacovigilance misuse/abuse signals related to semaglutide, a glucagon-like peptide-1 (GLP-1) analogue, in comparison to other GLP-1 receptor agonists (albiglutide, dulaglutide, exenatide, liraglutide, lixisenatide, and tirzepatide) and the phentermine–topiramate combination. To acheieve that aim, we analyzed the Food and Drug Administration’s FDA Adverse Events Reporting System (FAERS) dataset, performing a descriptive analysis of adverse event reports (AERs) and calculating related pharmacovigilance measures, including the reporting odds ratio (ROR) and the proportional reporting ratio (PRR). During January 2018–December 2022, a total of 31,542 AERs involving the selected molecules were submitted to FAERS; most involved dulaglutide (n = 11,858; 37.6%) and semaglutide (n = 8249; 26.1%). In comparing semaglutide vs. the remaining molecules, the respective PRR values of the AERs ‘drug abuse’, ‘drug withdrawal syndrome’, ‘prescription drug used without a prescription’, and ‘intentional product use issue’ were 4.05, 4.05, 3.60, and 1.80 (all < 0.01). The same comparisons of semaglutide vs. the phentermine–topiramate combination were not associated with any significant differences. To the best of our knowledge, this is the first study documenting the misuse/abuse potential of semaglutide in comparison with other GLP1 analogues and the phentermine–topiramate combination. The current findings will need to be confirmed by further empirical investigations to fully understand the safety profile of those molecules.

GLP-1 RAs may directly influence brain regions implicated in mood regulation, thereby affecting emotional and behavioral states.
“This suggests that GLP-1 RAs may directly influence these areas, thereby affecting emotional and behavioral states [81].”
From Exploring the Side Effects of GLP-1 Receptor Agonist: To Ensure Its Optimal Positioning (2025) · cites this paper as [81]
Discussion §3.2 describes GLP-1 receptors in reward-related brain regions and reports effects on food-related brain responses, craving, and drug-seeking behavior. It does not establish that the regions are implicated in mood regulation or that GLP-1 RAs affect emotional states; those parts extend beyond what the paper says. Page numbers are unavailable in our copy. (LLM, conf=0.83)
Experimental — accuracy not yet measuredGLP-1 receptors are distributed in multiple brain regions implicated in mood regulation, such as the hypothalamus, hippocampus, amygdala, and pancreas.
“GLP-1 receptors are distributed in multiple brain regions implicated in mood regulation, such as the hypothalamus, hippocampus, amygdala, and pancreas.”
From Exploring the Side Effects of GLP-1 Receptor Agonist: To Ensure Its Optimal Positioning (2025) · cites this paper as [81]
Discussion §3.2 says GLP-1 receptors occur in several brain regions involved in metabolism and energy balance, and discusses the amygdala in relation to reward. It does not identify the hypothalamus or hippocampus as receptor sites or describe these regions as involved in mood regulation; the pancreas is not a brain region. (LLM, conf=0.88)
Experimental — accuracy not yet measuredThe frequency at which clinicians are likely to meet people taking GIP/GLP-1 RAs will probably increase in the future.
“Furthermore, the use of these drugs also varies with time, and some people might not report using GIP/GLP‐1 RAs as they are now able to acquire them without physician prescription [106, 107]. Therefore, the frequency at which clinicians are likely to meet people taking these medications will probably increase in the future.”
The Discussion (page not available) reports increasing prescriptions for several GLP-1 drugs and identifies semaglutide use without a prescription. These findings support the premise of growing use, but the paper does not predict how often clinicians will encounter people taking GIP/GLP-1 receptor agonists in the future; that appears to be the citing authors’ inference.

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.
