abstract
BACKGROUND: Prescriptions of semaglutide, a glucagon-like peptide-1 receptor agonist administered weekly for Type 2 diabetes mellitus and obesity, are increasing. Adverse effects from semaglutide overdose are poorly described. We report adverse effects from three unintentional semaglutide overdoses upon initiation. CASE REPORTS: Case 1: A 53-year-old man unintentionally injected semaglutide 2 mg instead of the recommended 0.1 mg. Case 2: A 45-year-old woman unintentionally injected semaglutide 2.4 mg instead of 0.25 mg. Case 3: A 33-year-old woman injected semaglutide 1.7 mg. All three of these patients developed nonspecific gastrointestinal symptoms. No patient experienced hypoglycemia. DISCUSSION: These unintentional semaglutide overdoses occurred due to deficits in patient and prescriber knowledge, and evasion of regulated access to pharmaceuticals. Nonspecific gastrointestinal symptoms predominated. The potential for hypoglycemia following glucagon-like peptide-1 agonist overdose is unclear, though it did not occur in our patients. It is thought that glucagon-like peptide-1 agonists are unlikely to cause hypoglycemia because their effects are glucose-dependent and diminish as serum glucose concentrations approach euglycemia. There is, however, an increase in hypoglycemia when glucagon-like peptide-1 agonists are combined with sulfonylureas. CONCLUSIONS: This case series highlights the critical role of patient education and training upon initiation of semaglutide therapy to minimize administration errors and adverse effects from injection of glucagon-like peptide-1 receptor agonists.
