Granuflo/Naturalyte Dialysate Products Liability Litigation

GranuFlo and NaturaLyte, acid concentrates used in dialysis treatments, were linked to severe health risks, including cardiopulmonary arrest and sudden cardiac death. An internal memo from Fresenius Medical Care, leaked to the Food and Drug Administration (FDA) in 2012, revealed that the company was aware of over 900 life-threatening cardiac events associated with these products. This led the FDA to issue a Class 1 recall. In March 2013, multidistrict litigation began in the U.S. District Court for the District of Massachusetts, where founding partner Christopher Seeger served on the Plaintiffs' Executive Committee. In 2016, Fresenius settled over 4,000 lawsuits related to GranuFlo and NaturaLyte for $250 million, compensating patients and families affected by the dangerous side effects of these dialysis treatments.
