Sodium Bicarbonate Injection

Product Overview

Sodium Bicarbonate Injection (Preservative-Free) is a sterile, injectable formulation used to correct metabolic acidosis, alkalinize blood and urine, and manage certain drug-related toxicities and electrolyte disturbances. It serves as a systemic alkalinizing agent, helping restore normal acid–base balance in acute and critical care settings.

The preservative-free formulation is particularly suitable for sensitive patients, neonatal use, and high-dose or repeated administration, where avoidance of preservatives is clinically preferred.

This medication is available by prescription only and must be administered under licensed healthcare supervision.

Dosage & Administration

General Dosing Information

Dosage is highly individualized and depends on:

• Severity and cause of acidosis
• Patient age and body weight
• Serum bicarbonate, pH, and electrolyte levels
• Clinical response and ongoing monitoring

Typical Clinical Uses (Examples)

• Metabolic acidosis associated with renal failure, diabetic ketoacidosis, or shock
• Cardiac arrest and severe acidosis during resuscitation
• Urinary alkalinization
• Management of certain drug overdoses (e.g., tricyclic antidepressants, salicylates)
• Correction of hyperkalemia in specific clinical situations

Administration Details

• Administered intravenously (IV)
• May be given as a slow IV injection or diluted for infusion, as prescribed
• Use strict aseptic technique
• Inspect solution prior to use; do not use if cloudy, discolored, or containing particulate matter
• Flush IV line before and after administration to avoid incompatibility

Patients should not self-administer unless explicitly directed and trained by a healthcare provider.

Treatment Duration & Monitoring

Treatment duration depends on the underlying condition and response to therapy.

Monitoring may include:

• Arterial or venous blood gases (pH, bicarbonate)
• Serum electrolytes, particularly sodium and potassium
• Fluid status and renal function

Therapy should be adjusted based on laboratory values and the patient’s overall clinical status to avoid overcorrection.

Mechanism of Action

Sodium Bicarbonate Injection works by:

• Increasing plasma bicarbonate concentration
• Neutralizing excess hydrogen ions
• Raising systemic blood pH
• Enhancing buffering capacity of the blood

This action helps correct acid–base imbalances and stabilizes physiologic processes affected by acidosis.

Contraindications & Precautions

Sodium Bicarbonate Injection should be used with caution or avoided in patients with:

• Metabolic or respiratory alkalosis
• Hypernatremia or sodium retention
• Severe hypocalcemia
• Congestive heart failure or fluid overload
• Impaired renal function

Rapid administration or excessive dosing may result in alkalosis, electrolyte shifts, or volume overload.

Drug Interactions

Patients should inform their healthcare provider of all medications. Notable considerations include:

• Reduced effectiveness of medications requiring an acidic environment
• Altered elimination of weak acids and bases due to urine alkalinization
• Potential interactions with calcium salts and catecholamines in IV lines

Compatibility should be confirmed prior to mixing with other IV medications.

Adverse Reactions & Side Effects

Common

• Injection-site irritation or discomfort
• Fluid retention

Less Common / Serious

• Metabolic alkalosis
• Hypernatremia
• Hypokalemia
• Tetany due to reduced ionized calcium
• Tissue damage if extravasation occurs

Prompt monitoring helps minimize these risks.

Pregnancy & Breastfeeding

Sodium Bicarbonate Injection may be used during pregnancy or breastfeeding only when clearly indicated and under close medical supervision. Risk–benefit assessment is essential.

Storage & Handling

• Store at controlled room temperature per pharmacy guidelines
• Do not freeze
• Protect from excessive heat
• Preserve sterility; discard unused portions according to facility protocol
• Keep out of reach of children and pets
