Information for the public

Sodium zirconium cyclosilicate (Lokelma) is available on the NHS as a possible treatment for hyperkalaemia in adults, if used:

  • for acute life-threatening hyperkalaemia in emergency care alongside standard care or
  • for persistent hyperkalaemia for people with chronic kidney disease stage 3b to 5 or heart failure, if they:
    • have a confirmed serum potassium level of at least 6.0 mmol/litre and
    • because of hyperkalaemia, are not taking an optimised dosage of renin-angiotensin-aldosterone system (RAAS) inhibitor and
    • are not on dialysis.

Sodium zirconium cyclosilicate should be stopped if RAAS inhibitors are not longer suitable.

If you are not eligible for sodium zirconium cyclosilicate but are already taking it, you should be able to continue until you and your doctor decide when best to stop.

Is this treatment right for me?

Your healthcare professionals should give you clear information, talk with you about your options and listen carefully to your views and concerns. Your family can be involved too, if you wish. Read more about making decisions about your care.

Questions to think about

  • How well does it work compared with other treatments?
  • What are the risks or side effects? How likely are they?
  • How will the treatment affect my day-to-day life?
  • What happens if the treatment does not work?
  • What happens if I do not want to have treatment? Are there other treatments available?
