How it works

Klor-Con (Potassium Chloride) is a supplement that raises potassium levels in your blood. Potassium is essential for heart, nerve, and muscle function, and other important processes in your body. Blood potassium has to stay in a narrow range, so very small potassium level changes can have significant effects.

Skip risks section. Skip to common concerns section.
    • Higher risk if:
    • Dose of Klor-Con (Potassium Chloride) is too high
    • Dehydration
    • Heart problems
    • Kidney problems
    • Taking with medicines that increase potassium

    High levels of potassium in your body can cause muscle weakness/paralysis and serious heartbeat problems (loss of signal between upper and lower parts of the heart that result in lost beats, fast, abnormal heart beats in the ventricle and complete loss of heartbeat). Don't take Klor-Con (Potassium Chloride) with medicines that increase potassium (ACE inhibitors, potassium-sparing fluid pills, salt substitutes, etc.). Your doctor may order blood tests to check your potassium levels if you have a condition that could increase this risk.
