What is potassium chloride? 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. Potassium chloride may also be used for other purposes not listed in this medication guide.
Potassium is a simple mineral that is important for the regulation of our heartbeat. It, along with other electrolytes like sodium and chloride, helps to maintain the proper fluid and electrolyte balance, stimulates muscle contraction, and helps to regulate the acid and base balance in the body.
