Part of an ongoing effort to better oversee use of compounded medications.

In its continuing effort to ensure the safety and efficacy of compounded medications, the FDA yesterday issued a compounding risk alert about cesium chloride, which is sometimes used by cancer patients. The alert, issued to providers and patients, states that “serious adverse events associated with the use of cesium chloride and other cesium salts include abnormal heart rhythms (arrhythmias), low potassium (hypokalemia), seizures, fainting (syncope), cardiac arrest and death.”
