<h4>Objectives</h4>We hypothesized that semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1 RA) and treatment currently U.S. Food and Drug Administration (FDA) approved to reduce worsening of kidney disease and kidney failure may protect against lithium-induced nephrotoxicity.<h4>Methods</h4>Renal adverse events (AEs) reported to the FDA Adverse Event Reporting System (FAERS) between December 2003 and December 2024 were analyzed using the validated OpenVigil 2.1 platform. The gene discussed is GLP1R; the disease is kidney failure.
