Key facts
Potassium chloride is a potassium salt (oral solution) indicated, per the US prescribing information, for treatment and prophylaxis of hypokalemia when dietary measures or diuretic dose reduction are insufficient.
What it is used for
- Treatment and prophylaxis of hypokalemia with or without metabolic alkalosis when potassium-rich foods or diuretic dose reduction are insufficient
Dosing
- Adults, hypokalemia: 40 to 100 mEq daily in 2 to 5 divided doses; limit to 40 mEq per dose and 200 mEq in 24 hours
- Adults, maintenance or prophylaxis: typically 20 mEq per day
- Pediatric patients birth to 16 years, hypokalemia: initial 2 to 4 mEq/kg/day in divided doses; maintenance typically 1 mEq/kg/day
- If serum potassium is <2.5 mEq/L, use intravenous potassium instead
- Dilute with cold water and take with meals or immediately after eating
- Monitor serum potassium and adjust dose accordingly
Contraindications
- Patients on potassium-sparing diuretics
Important warnings
- May cause gastrointestinal irritation if given undiluted; increased dilution and taking with meals may reduce this
- In cardiac or renal disease or acidosis, attention to acid-base balance, volume status, electrolytes and ECG is required
Side effects
- Most common: nausea, vomiting, flatulence, abdominal pain/discomfort and diarrhea
Interactions
- Potassium-sparing diuretics: severe hyperkalemia possible; avoid concomitant use
- RAAS inhibitors (ACE inhibitors, ARBs, spironolactone, eplerenone, aliskiren): potassium retention, monitor closely
- NSAIDs: potassium retention, monitor potassium closely
Pregnancy and breastfeeding
- No human data; supplementation that does not lead to hyperkalemia is not expected to cause fetal harm
- With normal body potassium, little or no effect on potassium levels in human milk
