Potassium Chloride Tips from Pharmacists

  • Take the medicine with meals and a full glass of water to prevent throat irritation and stomach upset.

  • Swallow the potassium chloride tablet whole. Do not chew, crush, or suck it.

  • If you are taking the effervescent tablets or powder, dissolve it in at least 4 ounces (half cup) of water. Drink the mixture immediately.

  • You can sprinkle the contents of a potassium chloride capsule onto some cold, soft food like applesauce. Swallow the mixture immediately. Do not store it for later use. Drink a glass of water afterward to ensure you swallow all of the medicine.

  • Do not take sodium chloride (salt) substitutes without talking to your doctor first. They may contain potassium chloride and could lead to dangerously high potassium levels.
