Lidocaine Hydrochloride and Epinephrine Injection USP – Uses, Dosage & Side Effects


Lidocaine Hydrochloride and Epinephrine Injection USP – Uses, Dosage & Side Effects











 Introduction

Lidocaine Hydrochloride and Epinephrine Injection USP is one of the most commonly used local anesthetic solutions in dentistry and minor surgical procedures. The combination provides effective pain control, reduces bleeding, and prolongs the duration of anesthesia.



What is Lidocaine Hydrochloride and Epinephrine Injection?


Composition:

This injection is a mixture of:


  • Lidocaine Hydrochloride (HCl): A fast-acting local anesthetic that blocks nerve signals and provides numbness in a specific area.


  • Epinephrine (Adrenaline): A vasoconstrictor that narrows blood vessels, controls bleeding, and delays the absorption of lidocaine, ensuring longer-lasting pain relief.




Indications (Uses)


  • Dental procedures such as tooth extraction, fillings, and root canal treatment.


  • Minor surgical procedures requiring local anesthesia.


  • Helps in reducing operative bleeding due to vasoconstriction.




Mechanism of Action


  • Lidocaine works by blocking sodium channels in nerve membranes, preventing pain signal transmission.


  • Epinephrine constricts blood vessels at the injection site, which slows lidocaine absorption, prolonging anesthesia and reducing systemic toxicity.



Available Strengths


The commonly available formulations are:


  • 2% Lidocaine with Epinephrine 1:80,000


  • 2% Lidocaine with Epinephrine 1:100,000


  • 2% Lidocaine with Epinephrine 1:200,000




Dosage & Administration


  • Administered by infiltration or nerve block injection.


  • The maximum recommended dose for a healthy adult is 7 mg/kg of lidocaine (not exceeding 500 mg total) when used with epinephrine.


  • Dosage varies depending on patient’s age, weight, and medical condition.



Precautions


Contraindicated in: Patients allergic to amide-type anesthetics, those with severe cardiac arrhythmias, or hypersensitivity to epinephrine.


Use with caution in patients with:


  • Heart disease or hypertension


  • Hyperthyroidism


  • Diabetes


  • During pregnancy and lactation (only if necessary)



Possible Side Effects


  • Local effects: Pain, redness, or swelling at the injection site.


  • Systemic effects (rare):


  • Dizziness, headache


  • Increased heart rate or palpitations


  • Anxiety, restlessness, or tremors


  • Rarely, allergic reactions or seizures




Conclusion

Lidocaine Hydrochloride and Epinephrine Injection USP is a safe and effective anesthetic solution when used correctly. Its combination of quick pain relief and prolonged anesthesia makes it a standard choice in dental and surgical practices. However, it must always be administered by trained professionals with proper precautions.
