Multibic (Sodium Hydrogen Carbonate, Magnesium Chloride Hexahydrate, Potassium Chloride, Sodium Chloride, Calc)

Multibic is used in the context of renal replacement therapy and dialysis to maintain electrolyte and acid‑base homeostasis.

• Hemodialysis: helps maintain electrolyte concentrations and pH during the dialysis session.
• Renal replacement therapy: supplies necessary ions when native kidney function is insufficient.
• Electrolyte replacement during dialysis: prevents deficits of potassium, magnesium, calcium and sodium that can arise from the treatment.

• Multibic delivers sodium, potassium, calcium, magnesium ions and bicarbonate directly into the bloodstream during haemodialysis. The supplied bicarbonate acts as a buffer, correcting metabolic acidosis, while the mineral ions replenish those removed by the dialyzer, thereby preserving plasma electrolyte concentrations and supporting normal cardiac and neuromuscular function.

Multibic may be associated with infusion‑related reactions and electrolyte shifts.

Common Side Effects

• Mild hypotension: transient drop in blood pressure during infusion.
• Nausea or vomiting: gastrointestinal discomfort reported by some patients.
• Headache: occasional mild headache during or after administration.
• Transient electrolyte shifts: temporary changes in serum potassium or magnesium.
• Infusion site irritation: redness or mild pain at the catheter site.

Serious or Rare Side Effects

• Severe hyperkalemia: dangerous rise in potassium levels.
• Hypermagnesemia: excessive magnesium causing cardiac effects.
• Anaphylactic reaction: rare severe allergic response.
• Cardiac arrhythmia: irregular heart rhythm linked to electrolyte imbalance.
• Severe metabolic alkalosis: excessive bicarbonate leading to high pH.

Prior assessment and monitoring are essential when using Multibic.

• Baseline electrolyte assessment: check serum levels before infusion.
• Blood pressure monitoring: observe for hypotension during administration.
• Dialysate adjustment: tailor dialysate composition based on patient needs.
• Cardiac disease caution: use carefully in patients with known arrhythmias.
• Hypersensitivity avoidance: discontinue if allergic reaction occurs.
• Store at ambient temperature: keep in original container, protect from moisture and light.

Multibic can interact with other agents that affect electrolyte balance.

Major Interactions (Avoid)

• High‑potassium supplements: risk of hyperkalemia.
• Calcium‑containing medications: may cause hypercalcemia.
• Magnesium‑containing laxatives or antacids: increase risk of hypermagnesemia.
• Sodium bicarbonate infusions: can lead to severe metabolic alkalosis.

Moderate Interactions (Monitor Closely)

• Loop diuretics: may amplify electrolyte shifts.
• Antihypertensive drugs: additive blood pressure lowering effect.
• Anticoagulants used in dialysis: monitor for bleeding complications.
