Description
Amide local anesthetic and type IB antiarrhythmic
Used IV for acute, life-threatening ventricular arrhythmias; topically and locally for anesthesia
Continuous ECG monitoring necessary when given IV
Indications
Indicated for the treatment of perfusing ventricular arrhythmias including ventricular fibrillation (VF) and ventricular tachycardia (VT) that may result during acute myocardial infarction or cardiac manipulation (e.g., cardiac surgery).
Indicated as an anesthetic lubricant for oral or nasal endotracheal intubation
Indicated for temporary relief of pain and itching caused by minor skin irritations (eg, sunburn, minor burns, minor cuts, scrapes, insect bites, minor skin irritations)
Indicated for temporary pain relief in adults and adolescents aged ≥12 yr
Indicated for ocular surface anesthesia during ophthalmologic procedures
Indicated for pain, itching, and burning associated with hemorrhoids and other anorectal disorders
Contraindications
Hypersensitivity to lidocaine or amide-type local anesthetic
Adams-Stokes syndrome, SA/AV/intraventricular heart block in the absence of artificial pacemaker
CHF, cardiogenic shock, 2nd and 3rd degree heart block (if no pacemaker is present), Wolff-Parkinson-White Syndrome

- Allergic: Cutaneous lesions, urticaria, edema, or anaphylactoid reactions
lidocaine transdermal (Rx, OTC)
- Allergic and anaphylactoid reactions (rare) may be characterized by angioedema, bronchospasm, dermatitis, dyspnea, hypersensitivity, laryngospasm, pruritus, shock, and urticaria
- Application site reactions may occur (eg, blisters, bruising, burning sensation, depigmentation, dermatitis, discoloration, edema, erythema, exfoliation, irritation, papules, petechia, pruritus, vesicles, or abnormal sensation
lidocaine ophthalmic (Rx)
- Conjunctival hyperemia
- Corneal epithelial changes
- Headache
- Burning upon instillation
lidocaine rectal (OTC)
Application site reactions
Abnormal sensation
Pallor or blanching when the application time is very prolonged (>2 hr)
Alterations in temperature sensations
Edema
Itching
Rash
Systemic reactions
Unlikely due to the small dose absorbed; may occur with repeated doses or application to large surface area (see Cautions)
CNS excitation and/or depression
Light-headedness, nervousness, apprehension, euphoria, confusion
Dizziness
Drowsiness
Tinnitus
Blurred or double vision
Vomiting
Sensations of heat, cold or numbness
Twitching, tremors, convulsions
Unconsciousness, respiratory depression, and arrest
Cardiovascular manifestations (eg, bradycardia, hypotension, and cardiovascular collapse leading to arrest)
Warnings
Constant monitoring with an EKG is essential to the proper administration of lidocaine IV; discontinue immediately with signs of excessive depression of cardiac conductivity (eg, PR interval prolongation, QRS interval widening, arrhythmia exacerbation)
If malignant hyperthermia develops, discontinue administration immediately and institute therapeutic countermeasures as clinically indicated
Lidocaine hydrochloride should not be added to blood transfusion assemblies because of possibilities of pseudoagglutination or hemolysis
Not recommended as prophylaxis in acute MI (controversial)
Liver disease, CHF, bradycardia, Wolff-Parkinson-White syndrome, marked hypoxia, severe respiratory depression, hypovolemia, incomplete heart block
Use extreme caution in patients with severe hepatic impairment; may increase risk of lidocaine toxicity
Risk of lidocaine toxicity may increase in patients with pseudocholinesterase deficiency
Good for automatic and re-entrant arrhythmias, not PSVTs
Pregnancy and Lactation
Pregnancy Category: B
Present in human milk; published studies have reported a range of lidocaine milk: plasma ratios between 0.4-1.1
Maximum Dosage
NOTE: The dose of local anesthetics differs with the anesthetic procedure; the area to be anesthetized; the vascularity of the tissues; the number of neuronal segments to be blocked; the intensity of the block; the degree of muscle relaxation required; the duration of anesthesia desired; individual tolerance; and the physical condition of the patient.
100 mg/dose IV load (may repeat to a Max total load of 300 mg over a 1 hour period) for perfusing ventricular arrhythmias or 1.5 mg/kg/dose IV load (may repeat to a Max total load of 3 mg/kg) for ventricular arrhythmias during CPR; 4 mg/minute (50 mcg/kg/minute) IV continuous infusion for ventricular arrhythmias; maximum dosage for use as a topical or local anesthetic is dependent on the indication, route, and formulation used.
