What Calcium Resonium is used for
Calcium Resonium is a type of medicine used to help remove excessive amounts of potassium from the blood.
Calcium Resonium contains calcium polystyrene sulfonate which contains calcium atoms. This calcium is swapped for potassium in the body, particularly in the large intestine.
Calcium Resonium does not enter the bloodstream from the intestine. It is passed (with the potassium ions) with the faeces.
Your doctor, however, may prescribe Calcium Resonium for another purpose.
Ask your doctor if you have any questions about why it has been prescribed for you. This medicine is only available with a doctor's prescription.
Before you take it
When you must not take it
Do not take Calcium Resonium if you have:
- a bowel obstruction
- high calcium levels in the blood
- high levels of parathyroid hormone (PTH)
- multiple myeloma (a cancer of the blood) or sarcoidosis (an inflammatory disorder)
- low levels of potassium (less than 5 mmol/L).
Do not take Calcium Resonium if you are allergic to it or any of the ingredients listed at the end of this leaflet. Some symptoms of an allergic reaction include skin rash, itching, shortness of breath or swelling of the face, lips or tongue, which may cause difficulty in swallowing or breathing.
Do not give oral Calcium Resonium to newborn babies. Orally administered Calcium Resonium has caused bowel obstruction in newborns. Calcium Resonium should only be given rectally to newborns.
Do not take it if you are pregnant or intend to become pregnant.
Do not take it if you are breastfeeding or planning to breastfeed.
Do not take it after the expiry date (EXP) printed on the pack. If you take it after the expiry date has passed, it may not work as well.

Before you start to take it
Tell your doctor or pharmacist if you have allergies to:
- any of the ingredients listed at the end of this leaflet,

- any other substances, such as foods, preservatives or dyes.
Tell your doctor or pharmacist if you are pregnant or intend to become pregnant. Like most medicines of this kind, Calcium Resonium is not recommended to be used during pregnancy.

Tell your doctor or pharmacist if you have or have had any medical conditions, especially the following:
- thyroid conditions
- bone marrow (blood) disorders or tumours.
Tell your doctor if you plan to have surgery.
If you have not told your doctor or pharmacist about any of the above, tell them before you take Calcium Resonium.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food store.
Some medicines may interfere with Calcium Resonium. These include:
- digoxin, a medicine used for heart problems
- thyroxine, a medicine for hypothyroidism
- lithium, a medicine which can be used to treat bipolar disorder
- antacids containing aluminium or magnesium
These medicines may be affected by Calcium Resonium, or may affect how well it works. You may need to use different amounts of your medicine, or take different medicines. Your doctor or pharmacist will advise you.
Your doctor or pharmacist has more information on medicines to be careful with or to avoid while taking Calcium Resonium.
How to take it
How it is given
Calcium Resonium can be given by mouth or rectally (via the back passage).
How much to take
The amount of Calcium Resonium you need to take will depend upon the amount of potassium in your blood.
Your doctor will decide exactly how much Calcium Resonium you need to take. The usual doses are:
15 g three to four times daily. The spoon provided in the jar contains 15 g of powder when filled level.
1 g/kg of body weight in divided doses.
Calcium Resonium powder is usually given by mouth as a suspension in a small amount of water (3-4 mL per gram of powder), or it may be mixed with some sweetened liquid (but not fruit juices, which contain potassium). For children it is preferably given with a drink (not a fruit juice because of the high potassium content) or a little jam or honey.
Do not take Calcium Resonium with fruit juices or sorbitol. Once the mixture has been prepared it should be used straight away. If it needs to be stored, it should be stored for no longer than 24 hours. Once reconstituted, Calcium Resonium is a cream to light brown coloured suspension in which small white particles may be visible.
Rectal (via the back passage)
30 g in 150 mL of water or 10% dextrose in water, as a retention enema. Your pharmacist will make this up.
Infants & children:
Lower dosages are usually used.
Newborn babies (Neonates):
Calcium Resonium should not be given by mouth. With rectal administration the minimum effective dose range 0.5 g/kg to 1 g/kg should be used. This enema should be retained for at least nine hours. Afterwards the colon needs to be irrigated to remove the Calcium Resonium.
You will usually be given the enema by a doctor or nurse.
If you forget to take it
Do not try to make up for missed doses by taking more than one dose at a time. This may increase the chance of getting an unwanted side effect.
If it is almost time for your next dose, skip the dose you missed and take the next dose when you are meant to.
Do not take a double dose to make up for the dose you have missed.
If you are not sure what to do, ask your doctor or pharmacist.
If you take too much (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (telephone Australia 13 11 26 or New Zealand 0800 POISON or 0800 764 766), or go to Accident and Emergency at your nearest hospital, if you think you or anyone else may have taken too much Calcium Resonium.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Large doses of Calcium Resonium may cause serious potassium ion deficiency. If you take too much you may feel irritable, confused, have muscle weakness, have diminished reflexes or paralysis.
