Hypokalaemia

Borders Intranet - Electrolyte Deficiency

Treatment of hypokalaemia
Potassium bicarbonate + Potassium chloride
Sando-K effervescent tablets

Two tablets three times daily, dispersed in water. Dose may be altered according to serum levels.

Prescribing Notes:

  • Potassium-sparing diuretics are recommended instead of potassium supplements for prevention of hypokalaemia due to diuretics such as furosemide or thiazides when these are given to eliminate oedema. Long term use of potassium supplements is not generally recommended but if clinically indicated then serum potassium levels should be checked regularly.
  • Refer to local board hospital guidance and/or NPSA alert Discontinuation of Kay-Cee-L (potassium chloride 375mg/5ml) (potassium chloride 5mmol/5ml) syrup for further guidance on enteral product choices when Sando-K is not considered appropriate. 
  • Potassium chloride 600mg (potassium 8mmol) modified-release tablets are not preferred for potassium supplementation but may be considered in patients in whom effervescent tablets are considered inappropriate.
  • Consider parenteral replacement in severe potassium deficiency or in patients with ECG changes.
  • For information on potassium replacement in IV fluids refer to local secondary care IV fluid management guidelines.
  • Only premixed potassium chloride IV infusion bags should be used as per local guidelines. Awareness of the National Patient Safety Alert is also helpful - see ‘Potassium chloride concentrate solution - Patient Safety Alert’.
