Potassium Chloride Drug Information:

Potassium is a mineral that is found in many foods and is needed for several functions of your body, especially the beating of your heart. Potassium chloride is used to prevent or to treat low blood levels of potassium (hypokalemia). Potassium levels can be low as a result of a disease or from taking certain medicines, or after a prolonged illness with diarrhea or vomiting. You should not use potassium chloride if you have high levels of potassium in your blood (hyperkalemia), or if you also take a "potassium-sparing" diuretic. Learn more
