Taking Potassium

Your potassium supplement helps replace potassium your body has lost. This loss may be because of a medicine you take, such as a diuretic (water pill). Or it may be because of a medical condition you have.

Taking your potassium along with food helps prevent stomach upset or diarrhea.

Medication Tips

• Read the fact sheet that comes with your medication. It tells you when and how to take it. Ask for a sheet if you don’t get one.

• Always take your potassium along with food.

• If you take a long-acting tablet or capsule, swallow it with a full glass of water or juice. Do not crush or chew it unless you’re told it’s okay to do so.

• If you take potassium as granules, powder, fizzing tablets, or liquid, you must dilute it in at least 1 cup (8 oz) of cold water or juice. Wait for fizzing to stop before drinking the liquid. Then, sip slowly.

• If you miss a dose, take it as soon as you remember— unless it’s almost time for your next dose. If so, skip the missed dose. Do not take a double dose.

For Your Safety

• Talk to your doctor before changing the amounts of foods you eat that are high in potassium.

• Do not use salt substitutes or eat foods labeled low-sodium unless your doctor says it’s okay. Many contain potassium.

• Tell your doctor or pharmacist before taking any other prescription or over-the-counter medicines. This includes vitamin/mineral supplements and herbal remedies.

• Be sure to refill your prescription before you run out. And do not share your medicine with anyone.

• Check your blood pressure regularly as directed by your doctor.
