FDA warning: GranuFlo and NaturaLyte Dialysis Products

The U.S. Food & Drug Administration recently declared a Class I recall of Fresenius Medical Care’s GranuFlo and NaturaLyte dialysis products. After an internal Fresenius memo was leaked to the FDA, the company warned its customers that the products have been linked to elevated bicarbonate levels, a contributing factor in cardiac arrest.

FDA issued a Class I Recall notice for Fresenius Medical Care North America Naturalyte Liquid Acid Concentrate and Naturalyte GranuFlo (powder) Acid Concentrate. Inappropriate prescription of these products can lead to a high serum bicarbonate level in patients undergoing hemodialysis. This may contribute to metabolic alkalosis, which is a significant risk factor associated with low blood pressure, hypokalemia, hypoxemia, hypercapnia and cardiac arrhythmia, which, if not appropriately treated, may culminate in cardiopulmonary arrest. This product may cause serious adverse health consequences, including death.

Dialysate is a solution prescribed by physicians for use in the treatment of acute and chronic renal failure during the hemodialysis procedure. The dialysate solution is used in combination with the hemodialysis machine and dialyzer to remove wastes from the blood.

Health care providers should review the dialysate acid concentrate labeling for the specific concentrate that they prescribe to determine the components that can contribute to the patient’s overall bicarbonate levels. The levels of acetate, citrate and/or acetic acid vary by formulation and by manufacturer. Be aware that metabolic alkalosis (pre-dialysis serum bicarbonate levels > or = to 27 mEq/L) has been associated with a higher risk of death in hemodialysis patients.

Healthcare professionals and patients are encouraged to report adverse events or side effects related to the use of these products to the FDA’s MedWatch Safety Information and Adverse Event Reporting Program:
