- Side Effects
Oral formulations of sodium zirconium cyclosilicate.
10g three times daily until normokalaemia is achieved (typically within 24 to 48 hours).
If normokalaemia is not achieved after 72 hours of treatment, consider other treatment options.
Initially 5g once daily, with possible titration up to 10g once daily, or down to 5g once every other day.
The maximum maintenance dose is 10g once daily.
Patients on chronic haemodialysis
Dose only on non-dialysis days. Initially 5g once daily. Titrate the dose up or down weekly in increments of 5g up to 15g once daily in order to achieve normokalaemia. Titration should be based on the pre-dialysis serum potassium value after the long inter dialytic interval.
Empty the full contents of the sachet into around 45ml of water and stir well. The powder will not dissolve. The oral suspension should be drunk while still cloudy and if the powder settles should be stirred again to ensure all the contents are taken.
Children under 18 years
Precautions and Warnings
Restricted sodium intake
Contains more than 1 mmol (23 mg) sodium per dose
Advise patient not to take other medicines within 2 hours
Advise patient to report signs of gastrointestinal perforation immediately
Monitor serum potassium regularly
May affect X-ray images
Discontinue if severe hypokalaemia occurs
Limited experience exists in patients with serum potassium concentrations greater than 6.5mmol/L.
Sodium zirconium cyclosilicate may be opaque to X-rays.
Monitor serum potassium after dose titration and after changes are made to products that affect the serum potassium concentration (e.g. diuretics and renin-angiotensin-aldosterone system inhibitors). Once normokalaemia is established, potassium should be monitored regularly.
Long term treatment (more than 1 year) has not been studied.
Sodium zirconium cyclosilicate oral powder contains approximately 400mg sodium per 5g dose.

Sodium zirconium cyclosilicate is considered safe to use during breastfeeding.
The manufacturer advises that sodium zirconium cyclosilicate may be used during breastfeeding. The presence of sodium zirconium cyclosilicate in human milk is unknown but due to its physicochemical properties, sodium zirconium cyclosilicate is not systemically absorbed and is not expected to be excreted in breast milk.
It is strongly recommended that the UK National Poisons Information Service be consulted on cases of suspected or actual overdose where there is doubt over the degree of risk or about appropriate management.
