SAFETY ALERT: Alkali Dosing Errors in Dialysate Concentrates

Share this article:

The FDA is notifying health care providers to consider the presence and quantity of acetate, citrate, and/or acetic acid in dialysate concentrates when determining the patients' dialysate prescription.

This notice was issued following a complaint describing alkali dosing errors that occurred with dialysate concentrates containing acetic acid and acetate during hemodialysis. Dialysate is a solution prescribed by physicians for use in the treatment of acute and chronic renal failure during the hemodialysis procedure.

When metabolized, these potential sources of alkali can contribute to elevated bicarbonate levels in patients undergoing hemodialysis. This can lead to metabolic alkalosis, which is a significant risk factor associated with cardiopulmonary arrest, low blood pressure, hypokalemia, hypoxemia, hypercapnia, and cardiac arrhythmia.

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.
