Potassium supplements increase the amount of potassium in your body.
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.
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.
Some medicines available without a prescription may react with potassium supplements including:
Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
