Sodium Bicarbonate 8.4% is an alkalinizing agent used to buffer the pH of lidocaine solutions before injection, significantly reducing the pain and burning associated with local anesthetic administration. A practical procedural adjuvant for vein care and sclerotherapy practices.
Buffering lidocaine with Sodium Bicarbonate is one of the simplest, most impactful ways to improve patient comfort during sclerotherapy and other vein care procedures. Raising the pH of the lidocaine solution closer to physiological range allows more of the anesthetic to penetrate nerve membranes in its active form — improving both patient comfort and anesthetic onset speed.

Reduces lidocaine sting: The most common patient complaint during sclerotherapy is the burning sensation of lidocaine injection. Buffering virtually eliminates this.
Faster anesthetic onset: More active anesthetic molecules at physiological pH means faster numbing — saving chair time per procedure.
No effect on efficacy: Buffering does not reduce anesthetic or vasoconstrictive (epinephrine) effectiveness at standard dilution ratios.
Simple preparation: Standard 9:1 ratio (9 parts lidocaine to 1 part Sodium Bicarbonate 8.4%) — easy to implement with no specialized equipment.
Standard practice: 9 parts lidocaine to 1 part Sodium Bicarbonate 8.4%. For lidocaine with epinephrine, the same ratio applies. Follow your clinical protocol and current guidelines for specific preparation instructions.
Practices using Sodium Bicarbonate 8.4% typically combine it with Polidocanol 2% Injection, Lidocaine 1% Injection, and/or Lidocaine 1% with Epinephrine as part of a complete vein care procedural supply.
Contraindicated in patients losing chloride via vomiting or continuous GI suction, and in patients on diuretics causing hypochloremic alkalosis. Do not freeze. Use appropriate dilution ratios — 8.4% is a highly concentrated solution.
