Multibic (Sodium Hydrogen Carbonate, Magnesium Chloride Hexahydrate, Sodium Chloride, Calcium Chloride Dihydra)

Multibic is used as an electrolyte adjunct in renal replacement therapies, helping to correct imbalances that arise during dialysis.

• Hemodialysis: supports electrolyte and acid‑base homeostasis during treatment.
• Acute kidney injury: provides rapid replacement of lost electrolytes.
• Chronic renal failure: adjunct to regular dialysis sessions to maintain stable serum calcium, magnesium and bicarbonate levels.

• Multibic delivers a balanced mixture of sodium bicarbonate, magnesium, calcium and chloride ions directly into the bloodstream. The bicarbonate component buffers metabolic acids, while the added calcium, magnesium and chloride replenish ions lost during the dialysis process, helping to stabilize plasma pH and maintain cardiac and neuromuscular function.

Multibic may be associated with a range of infusion‑related reactions.

Common Side Effects

• Hypotension: transient drop in blood pressure during infusion.
• Nausea: mild gastrointestinal discomfort.
• Vomiting: occasional emesis.
• Headache: transient cephalic pain.
• Infusion site irritation: redness or mild pain at the catheter site.

Serious or Rare Side Effects

• Hypermagnesemia: elevated serum magnesium causing muscle weakness.
• Hypercalcemia: excess calcium leading to cardiac arrhythmia.
• Metabolic alkalosis: excessive bicarbonate raising blood pH.
• Severe electrolyte imbalance: may precipitate cardiac conduction disturbances.
• Anaphylactoid reaction: rare hypersensitivity with respiratory compromise.

When using Multibic, clinicians should observe several safety measures.

• Baseline assessment: evaluate serum electrolytes and acid‑base status before infusion.
• Blood pressure monitoring: watch for hypotensive episodes during administration.
• Cardiac monitoring: observe ECG for arrhythmias in patients with known heart disease.
• Infusion rate control: avoid rapid delivery in fluid‑overload prone individuals.
• Liver disease caution: adjust dosing in severe hepatic impairment.
• Store at ambient temperature: keep in original container, protect from light and moisture.

Multibic can interact with other medications that affect electrolyte balance or cardiovascular function.

Major Interactions (Avoid)

• Calcium channel blockers: may exacerbate hypercalcemia.
• Loop diuretics: increase risk of electrolyte shifts.
• ACE inhibitors: potentiate hypotensive effects.

Moderate Interactions (Monitor Closely)

• Antacids containing magnesium or calcium: may raise serum levels.
• Beta‑blockers: require blood pressure monitoring.
• Concurrent intravenous electrolyte solutions: avoid overlapping administrations to prevent overload.
