FDA Orders Eye Risk Warnings for Ozempic, Zepbound
The FDA on Monday ordered makers of GLP-1 drugs to warn of a potential increased risk of NAION. The condition is a rare optic nerve disorder that can cause sudden blindness.
- The rule covers Ozempic, Wegovy, Mounjaro, Zepbound and older GLP-1 diabetes drugs.
- NAION cases have been reported for every GLP-1 drug now on the market.
- FDA scientists could not identify how the drugs might raise the risk.
- 1 in 10,000 semaglutide users may develop NAION, the EMA estimated.
Why it matters: About 15% of U.S. adults, roughly 40 million people, have used a weight loss drug. The FDA now says patients and caregivers should know about the vision risk.
- NAION damage is often permanent, and no known treatment exists.
- Diabetes, sleep apnea and hypertension raise NAION risk and are common among GLP-1 users.

Right coverage, 3 sources: The right frames it around the blindness risk to users and the patients now suing the drugmakers.

- Nearly 100 lawsuits have been filed against Novo Nordisk since 2025, with fewer against Eli Lilly.
- How common is NAION among people taking GLP-1 drugs?
- Is the risk caused by the drugs or by the conditions their users already have?
