Semaglutide use is associated with a significantly higher reporting odds ratio for vision impairment and retinopathy compared to other GLP-1 receptor agonists, DPP-4 inhibitors, SGLT2 inhibitors, metformin, phentermine, and orlistat.
If you are taking semaglutide, be aware that there is a statistical signal for increased vision impairment reports in post-market data compared to other diabetes or weight loss drugs. This does not mean everyone will experience this, but it warrants vigilance. Ensure you have regular ophthalmological check-ups, especially if you have pre-existing diabetic retinopathy or rapid glycemic changes, and report any visual disturbances to your provider immediately.
Semaglutide showed significantly higher reporting of vision impairment compared to other GLP-1 receptor agonists (rOR 1.95, 95% CI 1.75–2.17, p < 0.0001), DPP-4 inhibitors (rOR 2.46, 95% CI 2.12–2.86, p < 0.0001), SGLT2 inhibitors (rOR 3.89, 95% CI 3.35–4.51, p < 0.0001), and metformin (rOR 2.23, 95% CI 1.90–2.62, p < 0.0001).
Why this rating
FAERS data is observational and subject to reporting bias; the paper explicitly states it cannot make causal inferences.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
