GranuFlo and NaturaLyte

Popular dialysis products, GranuFlo and NaturaLyte, have been linked to an increased risk of cardiopulmonary arrest and sudden cardiac death. Manufacturer of the products, Fresenius Medical Care (FMC) failed to warn patients and doctors of the dangers associated with the drugs until this year, even though there is documented evidence that they were aware of the risks.

Over 30 percent of all dialysis patients across the country are given one of these drugs, leaving them at a six-fold increased risk of cardiopulmonary arrest and sudden cardiac death.

If either of these products has been used in your dialysis treatment, we urge you to speak with an attorney as soon as possible.

Fresenius Medical Care was Aware of Risks

On March 29, 2012, the Food and Drug Administration (FDA) issued a Class 1 recall of both GranuFlo and NaturaLyte. A Class 1 recall is the most serious type of recall as it involves situations where there is a reasonable probability of adverse health consequences or death.

Between January 1 and December 31, 2010, Fresenius Medical Care conducted a case-control study that evaluated risk factors in dialysis patients who suffered from cardiopulmonary arrest in FMC facilities compared to other dialysis patients in the same facilities.

This study found that 841 patients in 667 FMC facilities had cardiopulmonary arrests resulting in their death. Data from these 941 patients showed that their risk of cardiopulmonary arrest was up to six times higher if they had an elevated bicarbonate level before undergoing dialysis treatment.

Fresenius Medical Care sent an internal memo to FMC’s doctors and dialysis facilities, recommending action for patients with elevated pre-dialysis bicarbonate levels. They failed to inform those outside of FMC, however. They only shared knowledge of the risk after the internal memo had been leaked to the FDA.
