Metformin NDMA Contamination Settlement 2026 -- File a Claim by July 10

What happened

Class period: July 20, 2015 through June 2, 2020

• Generic metformin drugs sold by Teva, Granules, and Heritage were allegedly contaminated with N-nitrosodimethylamine (NDMA), a substance that does not meet FDA standards for metformin
• The manufacturers are accused of falsely advertising these drugs as equivalent to brand-name Glucophage and Glucophage XR when they were not
• Consumers and third-party payors such as health insurers paid for drugs they claim they would not have purchased had they known about the contamination
• Three companies have agreed to settle: Teva for $3 million and Granules and Heritage jointly for $2.55 million, totaling $5.55 million
• The lawsuit does not include personal injury or wrongful death claims -- this settlement covers only the economic harm of paying for an adulterated product
• The case continues against non-settling defendants Amneal Pharmaceuticals and Walmart
