What does it do?

Potassium supplements increase the amount of potassium in your body.

Before you start

• Tell your doctor if you have heart, kidney, or bowel problems.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take potassium supplements regularly as directed.
Take the tablets (e.g. Span K®) with food and a glass of water. Swallow the tablets whole.
Dissolve effervescent tablets (e.g. Chlorvescent®) in a glass of water before swallowing. Take with food.
Do not lie down for a few minutes after taking each dose.

What if you forget a dose?

Take the missed dose as soon as possible. If it is close to the time for your next dose, skip the missed dose and carry on as normal. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with potassium supplements including:

• salt substitutes that also contain potassium (e.g. Lo Salt®)
• supplements that also contain potassium (e.g. Phosphate Sandoz®, Centrum®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
