Hundreds of lawsuits accuse Novo Nordisk’s Ozempic and Wegovy and Eli Lilly’s Mounjaro and other GLP-1 drugs of causing permanent vision loss. Plaintiffs argue the companies should have known about the risk but did not disclose it on U.S. warning labels. One 63-year-old man with diabetes allegedly lost vision in one eye after taking Ozempic and later became legally blind, and a Phoenix law firm says it has received nearly 200 inquiries, with some cases filed in states including Arizona.

Taiwan Semiconductor Manufacturing Co. is investing another $100 billion to expand its north Phoenix wafer-fab complex, a project that uses 4.75 million gallons of water per day. The company says its onsite system currently recycles 65% of that intake—about 3.5 million gallons daily—and it aims to lift reuse to 90% or more by 2028. The unrecycled portion has raised questions from residents and water policy experts about long-term supply in a desert region facing Colorado River cuts.
