Cesium Salt Supplements Can Cause Heart Trouble, Death

On February 5, 2020, the FDA posted an alert warning consumers not to use dietary supplements containing cesium chloride or any other cesium salt. Consuming cesium salt has significant safety risks, including heart toxicity, cardiac arrhythmias, hypokalemia (low potassium), seizures, fainting, and death.

Cesium salts are sometimes promoted as alternative treatments for cancer. However, they have not been shown to be safe or effective as a cancer treatment. Supplements containing cesium salts are rare, but consumers should still be aware of the risks associated with them and avoid purchasing and using such products.

If someone experiences an adverse effect while using a supplement containing cesium salts, they should stop using the product, seek medical care, and report the event to the FDA's Safety Reporting Portal. Consumers can also call an FDA Consumer Complaint Coordinator to speak directly to a person about a complaint or adverse event.
