Public Citizen v. FDA Cesium Chloride

On July 23, 2018, Public Citizen submitted a citizen petition to the Food and Drug Administration (FDA) requesting that it require the immediate removal from the market of all dietary supplements containing cesium chloride or any other cesium salt and that it issue a safety communication advising consumers and health professionals about the harms that can result from supplementation with cesium chloride or other cesium salts.   Although the FDA had acknowledged the safety risks posed by cesium chloride, more than a year passed without a substantive response from the agency. Accordingly, Public Citizen filed suit to compel the FDA to respond to the petition. After we filed suit, FDA responded to the petition, and we dismissed the lawsuit.
