Numerous medical studies have been published in the past couple of years about non-arteritic anterior ischemic optic neuropathy (NAION) with Ozempic, Wegovy, Mounjaro, or Zepbound use resulting in sudden vision loss.
Despite this drug safety information, the current Prescribing Information documents or drug labels in the US for these four increasingly popular drugs still do not have any warnings for doctors or patients about NAION and vision loss as of October 2026.
Before we point out two recent medical news articles relevant to NAION with Ozempic, Wegovy, Mounjaro, or Zepbound use, and whether their respective drug labels should have NAION and vision loss warnings, here are a couple of earlier pieces we wrote about those issues:
NAION Linked To Zepbound, Mounjaro, Ozempic, Wegovy: 2026 News Update (5/22/26)
Ozempic Eye Side Effect NAION Warnings Update July 2026 (7/28/26)
Now for the two recent medical news articles about NAION with Ozempic, Wegovy, Mounjaro, or Zepbound use, as well as the present lack of any NAION and vision loss warnings here in the US:
- “GLP-1s may be linked to vision loss, but overall risk ‘very, very low’“, published online October 2, 2026, by Healio Primary Care Optometry News; and
- “GLP-1s and NAION: Do Patients Need a Warning?“, published online October 2, 2026, by Medscape Medical News.
From talking to numerous people who have vision loss due to NAION diagnosed while using Ozempic and Wegovy (which are both semaglutide-containing drugs), as well as Mounjaro and Zepbound (which are both tirzepatide-containing drugs), we can tell you that many of these people said they were disappointed there were no NAION and vision loss warnings. Moreover, some of those people were understandably angry about this failure by the responsible drug companies.
We have been investigating drug injury lawsuits against those drug companies for patients who have vision loss due to NAION with Ozempic, Wegovy, Mounjaro, or Zepbound use.
