Micro-Kalium (Potassium Chloride)

Micro‑Kalium (potassium chloride) is used to correct low serum potassium levels in disorders of electrolyte balance.

• Hypokalemia: restores normal potassium concentrations, reducing symptoms such as muscle weakness and cardiac irregularities.
• Potassium deficiency: replenishes depleted potassium stores during conditions like prolonged vomiting or diarrhoea.
• Diuretic‑induced potassium loss: counteracts potassium depletion caused by loop or thiazide diuretic therapy.

• Potassium chloride dissociates in the gastrointestinal tract to release potassium ions (K⁺). The absorbed K⁺ enters the extracellular fluid, increasing serum potassium concentration. Elevated extracellular potassium restores the normal electrochemical gradient across cell membranes, which is essential for nerve impulse transmission, muscle contraction, and cardiac electrical activity. By directly supplying the deficient ion, the product helps re‑establish electrolyte balance without influencing hormonal pathways.

Potassium chloride may cause adverse reactions, ranging from mild gastrointestinal discomfort to serious electrolyte disturbances.

Common Side Effects

• Nausea
• Vomiting
• Abdominal discomfort
• Diarrhea

Serious or Rare Side Effects

• Hyperkalemia (elevated blood potassium)
• Cardiac arrhythmia
• Severe allergic reaction (e.g., rash, swelling)

When using Micro‑Kalium, clinicians should observe several safety measures to minimise risks and ensure therapeutic effectiveness.

• Monitor serum potassium: check levels before initiation and periodically during therapy.
• Adjust dose in renal impairment: reduce dosage or increase monitoring in patients with reduced kidney function.
• Use caution in cardiac disease: evaluate risk of arrhythmias in patients with underlying heart conditions.
• Avoid in existing hyperkalemia: do not administer if serum potassium is already elevated.
• Review concomitant medications: assess other drugs that may increase potassium levels.
• Store at ambient temperature: keep in the original container, protect from moisture and heat.

Potassium chloride can interact with other medicines, altering potassium balance or cardiac function.

Major Interactions (Avoid)

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

Moderate Interactions (Monitor Closely)

• Digoxin: high potassium may diminish digoxin efficacy and increase toxicity risk.
• Trimethoprim‑sulfamethoxazole: can raise potassium concentrations.
• Insulin or beta‑agonists: may cause rapid shifts of potassium into cells, affecting serum levels.
