Lidocaine HCL 2%

Lidocaine HCL 2%

• A. Light blue
• B. Gold
• C. Blue
• D. Green

Answer: (A)

Color coding helps you quickly identify the exact anesthetic solution in the cartridge. In many standard systems, the light blue cartridge denotes lidocaine hydrochloride 2% with epinephrine (typically 1:100,000). This combination is widely used because lidocaine 2% provides reliable anesthesia and the epinephrine constricts blood vessels, prolonging duration and improving hemostasis. The other colors signal different anesthetics or vasoconstrictor concentrations, so they aren’t the lidocaine 2% with epinephrine match.
