Indications:
For use in patients requiring supplemental potassium therapy.
Dosage and Administration:
The goal of potassium replacement therapy is to elevate the plasma concentration of the ion to within the normal range.
Dose per day: Since the normal dietary intake of potassium is 50 to 100mmol daily, it is rare that a larger amount is required during potassium replacement therapy.
Precautions & Warning:
Administration
• Only use with specialist advice
• ECG should be used throughout and monitored continuously
• High concentrations of potassium cause serious cardiotoxicity, so the concentration of the solution should not exceed 3g (40mmol)/L and the diluted solution given slowly
• Initially do not use with glucose infusions - glucose may further decrease potassium levels
Other concurrent treatment
• Extreme caution in patients on potassium sparing diuretics and other drugs that may increase potassium
• Glucose infusion
Monitoring
• Continuous ECG monitoring - see above Administration
• Regular potassium levels especially in patients with renal impairment
Underlying conditions
• Dehydration must be corrected to ensure adequate urinary output (and potassium excretion)
• Where renal excretion of potassium or cellular uptake deficient - life threatening hyperkalaemia can occur with standard doses
• Extreme caution with extensive tissue destruction (eg burns)
• Extreme caution in cardiac disease
Storage instructions:
Keep in outer carton. Do not store above 25°C.
