(MENAFN- EIN Presswire) EINPresswire/ -- Cowper Law LLP and DiCello Levitt have filed a federal class action lawsuit against Dexcom, Inc. on behalf of consumers who purchased Dexcom's G7 Continuous Glucose Monitors (CGMs). The lawsuit alleges that Dexcom misled patients and healthcare providers about the G7's safety, accuracy, efficacy, and reliability in monitoring blood glucose levels. The case, Grisoli v. Dexcom, Inc., et al., was filed in the U.S. District Court for the Central District of California (Case No. 8:25-cv-02333).

“For millions of people living with diabetes, technology isn't optional - it's a matter of life and death,” said attorney Moze Cowper, founding partner of Cowper Law LLP.“Our lawsuit seeks accountability for Dexcom's misleading claims about a medical device patients depend on every hour of every day.”
The complaint details that Dexcom marketed the G7 as“the most accurate” and“best in class” CGM, despite mounting safety issues. On March 4, 2025, the FDA issued a Warning Letter to Dexcom following an inspection that found the G7 devices were“adulterated.” Subsequently, on June 16, 2025, and September 4, 2025, the FDA announced two nationwide Class I recalls-its most serious designation-due to G7 components that could fail or delay critical high- and low-glucose alerts. The complaint also alleges the G7 sensors frequently fail before the ten days that they are advertised to last, forcing patients to replace them early and incur additional costs.

“Medical device manufacturers must be held to the highest standards, and patients and providers deserve transparency, especially when lives are on the line,” said DiCello Levitt founding Partner Adam Levitt.“This lawsuit is about demanding accountability from a company that failed to deliver on its promises.”

The lawsuit asserts violations of multiple consumer protection and warranty laws, including the California Consumers Legal Remedies Act (CLRA), Unfair Competition Law (UCL), and False Advertising Law (FAL), as well as express and implied warranty provisions under the Song–Beverly Consumer Warranty Act, the Magnuson-Moss Warranty Act, and related common law claims.
