Potassium Chloride

Potassium Chloride is an electrolyte used to prevent or to treat the deficiency of potassium caused by certain diseases, severe or prolonged episodes of vomiting or diarrhea, surgery, or other conditions. Potassium is necessary for many functions of the body, especially beating of the heart. It works by providing potassium when you have low levels of potassium in your blood.

Special Warnings

In patients with impaired mechanisms for excreting potassium, the administration of potassium salts can produce hyperkalemia and cardiac arrest.
Inform your doctor if you:

  • have kidney disease;
  • are taking a potassium-sparing diuretic;
  • have Addison’s disease;
  • have an ulcer or an intestinal blockage;
  • have chronic diarrhea;
  • pregnant, plan to become pregnant, or breastfeeding;
  • are allergic to any ingredients in Potassium Chloride.


  • Take each dose with a full glass of water.
  • Take Potassium Chloride with food or milk to lessen stomach upset.
  • Do not crush, chew, or break the tablets or capsules.
  • Do not use a salt substitute while taking K-dur as it may lead to excess of potassium in your body.
