According to a July 15 article in the Boston Herald, the number of lawsuits involving the use of dialysis products GranuFlo and NaturaLyte being heard in two Massachusetts courts now exceeds 5,000, the national law firm of Baron and Budd reports. The plaintiffs allege that the manufacturer of these products, Fresenius Medical Care – which also owns thousands of dialysis clinics across the United States – knew about health risks associated with GranuFlo and NaturaLyte, yet chose not to warn dialysis clinics. (

Plaintiffs have brought a combined 5,494 cases against Fresenius Medical Care, the manufacturer of the drugs. Of these cases, 3,694 of them have been filed in Middlesex Superior Court, with another 1,800 cases filed in the U.S. District Court in Boston. (In re: Fresenius GranuFlo/Naturalyte Dialysate Litigation, MDL No. 2428)

The plaintiffs in the cases cite a memo that was circulated internally within Fresenius concluding that use of GranuFlo could result in serious cardiac issues in patients. Use of the products can lead to a condition known as metabolic alkalosis, a dangerous increase in the blood’s bicarbonate levels. The condition can increase the risk of sudden cardiac arrest, heart attacks and additional cardiovascular problems.

The U.S. Food and Drug Administration (FDA) investigated these medical devices in 2012, which resulted in a Class 1 recall regarding the labeling of the products. According to the article, a Fresenius spokesperson said that the FDA has neither requested that products be taken off the market nor suggested any sort of change to the formulation of the products.

“What the Fresenius spokesman said in the article does not take away from the fact that many, many people have suffered devastating health issues after undergoing dialysis treatments that included GranuFlo or NaturaLyte,” said Laura Baughman, shareholder at the national law firm of Baron and Budd. “The growing number of cases highlights just how serious this problem really is.”
