Could Wegovy Raise Optic Nerve Risk?
A pharmacovigilance analysis of FDA adverse event reports finds the strongest ischemic optic neuropathy reporting signal with high-dose semaglutide formulations, with higher adjusted odds reported in men.
A global pharmacovigilance analysis of over 30 million reports revealed that the higher-dose 2.4-mg weekly formulation of semaglutide (Wegovy) is linked to a markedly increased risk of ischemic optic neuropathy (ION) compared to the lower-dose formulation (Ozempic). The risk was approximately 4.7 times higher in Wegovy, particularly among men. The study, led by Moiz Lakhani from the University of Ottawa, emphasized the need for personalized therapy and further studies to ascertain a causal relationship, as current data cannot establish incidence.
1. Higher-dose semaglutide (Wegovy) shows increased ION risk. 2. Risk is 4.7 times higher compared to lower-dose (Ozempic). 3. 31,774 reports of semaglutide associated with ION identified. 4. Strongest risk signal found in men taking Wegovy. 5. No ION reports with Rybelsus. 6. Analysis cannot establish causality. 7. Recommendations for longitudinal studies to assess risk. 8. Emphasis on personalized therapy for GLP-1 administration.
