PURPOSE: An increasing number of anecdotal reports on social media platforms and medical blogs describe dysesthesia, particularly burning skin sensations, in association with glucagon-like peptide-1 receptor (GLP-1R) agonists. We performed a pharmacovigilance data-mining analysis to characterise cases of dysesthesia related to GLP-1R.
METHODS: We conducted a disproportionality analysis using VigiBase data on GLP-1R (Anatomical Therapeutic Chemical classification: ATC code A10BJ) and tirzepatide, focusing on the HLT (High Level Term) "Paraesthesia and dysesthesia", with the Information Component (IC). Additionally, we reviewed all narratives of dysesthesia cases in the French Pharmacovigilance database to extract clinical and pharmacological characteristics. A literature review complemented this analysis.
RESULTS: Exenatide was significantly associated with hypoesthesia or oral paraesthesia, semaglutide and tirzepatide with hyperaesthesia, and semaglutide with dysesthesia and burning sensation. Dysesthesia appears to be dose-dependent, occurring more frequently at higher doses and with more potent GLP-1R, whether used for weight management or type 2 diabetes. Discontinuation was often performed, followed by spontaneous favourable outcomes, and cases of rechallenge were observed. Skin burning sensations represent a distinctive form of dysesthesia.
CONCLUSION: Pharmacovigilance quantitative and qualitative data strengthens evidence for dysesthesias associated with GLP-1R agonists already observed in clinical trials of semaglutide, tirzepatide, and retatrutide.
