Kaliumchloride Fresenius Kabi Nederland (Potassium Chloride)

Potassium chloride is used to restore potassium levels in conditions associated with electrolyte imbalance.

• Hypokalemia: restores normal serum potassium concentration and supports cardiac and muscular function.
• Potassium loss from diuretic therapy: replenishes depleted potassium stores to prevent cramps and weakness.
• Post‑operative potassium loss: repletes potassium to maintain physiologic balance.
• Severe burns or trauma: provides potassium needed for cellular recovery and electrolyte homeostasis.

• Potassium chloride delivers potassium ions directly into the bloodstream, raising extracellular potassium concentration. The increased serum potassium shifts the electrochemical gradient, facilitating normal cellular membrane potential, nerve impulse transmission, and muscle contraction. By correcting the deficit, it helps re‑establish electrolyte homeostasis and supports cardiac rhythm stability.

Common Side Effects

• Infusion site irritation: redness, pain, or swelling at the injection site.
• Mild hyperkalemia: transient elevation of serum potassium.
• Nausea or vomiting: gastrointestinal discomfort during infusion.
• Muscle weakness or tingling: sensations of numbness or reduced strength.
• Hypotension: slight drop in blood pressure during rapid administration.

Serious or Rare Side Effects

• Cardiac arrhythmia: potentially life‑threatening rhythm disturbances.
• Severe hyperkalemia: marked elevation of potassium leading to cardiac arrest.
• Anaphylactic reaction: severe allergic response requiring immediate intervention.
• Vein thrombosis: clot formation at the infusion site.
• Fatal outcomes: rare but possible in cases of extreme electrolyte imbalance.

Potassium chloride should be used with caution and under close medical supervision.

• Renal impairment: monitor serum potassium closely to avoid accumulation.
• Cardiac disease: use cautiously, watch for arrhythmias.
• Hyperkalemia: contraindicated in patients with elevated potassium levels.
• Rapid infusion: avoid exceeding recommended infusion rates to reduce cardiac risk.
• Compatibility: verify compatibility with other IV solutions before mixing.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Potassium chloride may interact with several medications that affect potassium balance.

Major Interactions (Avoid)

• ACE inhibitors: may cause dangerous hyperkalemia.
• Potassium‑sparing diuretics (e.g., spironolactone): increase risk of hyperkalemia.
• ARBs: additive potassium increase.
• NSAIDs: can reduce renal potassium excretion, raising levels.

Moderate Interactions (Monitor Closely)

• Beta‑blockers: may mask symptoms of hyperkalemia.
• Digoxin: hyperkalemia can enhance digoxin toxicity.
• Insulin: may shift potassium intracellularly, affecting levels.
• Loop or thiazide diuretics: may require dose adjustments.
