DexCom Inc. is facing a class action securities lawsuit filed on behalf of investors who suffered losses between January 8, 2024, and September 17, 2025. The lawsuit alleges that DexCom made unauthorized material design changes to its G6 and G7 glucose monitoring products without FDA approval, which made the devices less reliable and posed significant health risks to users. It is also claimed that the company overstated the reliability, accuracy, and functionality of the G7 device, while downplaying the severity of the issues and risks associated with the altered products. As a result, DexCom is accused of making materially false or misleading public statements, exposing the company to regulatory scrutiny and potential financial and reputational harm. The litigation is being handled by the law firm Levi & Korsinsky.
