American Regent Drug Recall: Silicon Particles in Calcium Gluconate

One lot of calcium gluconate injections distributed by American Regent has been recalled due silicone particle contamination. 

The American Regent calcium gluconate recall was announced by the FDA on July 18, after some vials were found to contain particulate matter. The particles could disrupt blood flow in the small blood vessels of the lungs, cause inflammation and granuloma formation.

The recall notice did not explain how the silicon particles contaminated the vials, but indicated that there have been no reports of injuries from contaminated calcium gloconate injections.
