What is Potassium Chloride? Potassium Chloride 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.
Potassium Chloride dosage. Take potassium chloride exactly as prescribed by your doctor. Follow the directions on your prescription label carefully. Dose amount is determined according to the individual needs of each patient:
- For the prevention of hypokalemia: typically in the range of 20 mEq per day
- For treatment of potassium depletion: typically in the range of 40-100 mEq per day or more
Dosage should be divided if more than 20 mEq per day. No more than 20 mEq is given in a single dose.
