Overview
Drug | Injection
Uses & Benefits
Local anesthesia for minor surgical/dental procedures, infiltration/field block/nerve block anesthesia, topical anesthesia on mucous membranes (as per clinical use); may also be used by specialists for certain cardiac arrhythmias when IV lidocaine is indicated (strength/form dependent)
How It Works
Lidocaine is an amide-type local anesthetic that reversibly blocks voltage-gated sodium channels in nerve membranes. This prevents initiation and conduction of nerve impulses, producing temporary loss of sensation in the area.

Avoid use in known hypersensitivity to amide-type local anesthetics. Resuscitation equipment and monitoring should be available.
Drug Interactions
Other local anesthetics (additive toxicity), class I antiarrhythmics (e.g., mexiletine, procainamide) and amiodarone (additive cardiac effects), beta-blockers (e.g., propranolol) and cimetidine (may increase lidocaine levels), CYP inhibitors, sedatives/CNS depressants (increased CNS effects)
