  • Keep out of reach of children and pets. Accidental ingestion can be dangerous.

Dosing & Administration

đŸ‘¨â€âš•ī¸

Adult Dosing

Standard Dose: Apply 2% jelly to the affected area as needed. Maximum recommended dose is 5 mg/kg (2.5 mL of 2% jelly per 5 kg body weight) in a single application, not to exceed 300 mg (15 mL of 2% jelly) in a 12-hour period.

Condition-Specific Dosing:

mucousMembranes: Apply a thin layer to the mucous membrane for anesthesia. For procedures like cystoscopy, instill 6-10 mL into the urethra.
skin: Not typically used for intact skin; primarily for mucous membranes or broken skin for local anesthesia.
đŸ‘ļ

Pediatric Dosing

Neonatal: Not established. Use with extreme caution due to risk of systemic toxicity.
Infant: Dosing should be calculated based on weight (e.g., 2.5-3 mg/kg) and not exceed 4.5 mg/kg in a single application. Max 300 mg/24 hours. Use smallest effective amount.
Child: Dosing should be calculated based on weight (e.g., 2.5-3 mg/kg) and not exceed 4.5 mg/kg in a single application. Max 300 mg/24 hours. Use smallest effective amount.
Adolescent: Dosing should be calculated based on weight (e.g., 2.5-3 mg/kg) and not exceed 4.5 mg/kg in a single application. Max 300 mg/24 hours. Use smallest effective amount.
âš•ī¸

Dose Adjustments

Renal Impairment:

Mild: No specific adjustment needed for topical application with limited systemic absorption.
Moderate: No specific adjustment needed for topical application with limited systemic absorption.
Severe: Use with caution. While systemic absorption from topical jelly is low, accumulation of lidocaine or its metabolites could occur with extensive use or impaired skin barrier. Monitor for signs of toxicity.
Dialysis: Considerations: Use with caution. Monitor for signs of toxicity if significant systemic absorption is anticipated.

Hepatic Impairment:

Mild: No specific adjustment needed for topical application with limited systemic absorption.
Moderate: Use with caution. Lidocaine is primarily metabolized by the liver. Reduced metabolism could lead to higher systemic levels if significant absorption occurs. Monitor for signs of toxicity.
Severe: Use with caution. Lidocaine is primarily metabolized by the liver. Reduced metabolism could lead to higher systemic levels if significant absorption occurs. Monitor for signs of toxicity.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Lidocaine stabilizes the neuronal membrane by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthetic action. It blocks voltage-gated sodium channels in the neuronal cell membrane, preventing depolarization and propagation of action potentials.
📊

Pharmacokinetics

Absorption:

Bioavailability: Variable (depends on site of application, duration of exposure, and integrity of skin/mucous membrane). Systemic absorption is generally low from intact skin but significantly higher from mucous membranes or abraded skin.
Tmax: Variable, typically 10-60 minutes after topical application to mucous membranes.
FoodEffect: Not applicable for topical formulation.

Distribution:

Vd: 0.7-2.7 L/kg (systemic)

Drug Interactions

🔴

Major Interactions

  • Antiarrhythmics (Class I, e.g., mexiletine, tocainide): Increased risk of cardiac depression and CNS effects if significant systemic absorption occurs.
  • Other local anesthetics: Additive systemic toxicity (CNS, cardiovascular) if significant absorption occurs.
🟡

Moderate Interactions

  • Beta-blockers (e.g., propranolol): May reduce hepatic blood flow, potentially decreasing lidocaine clearance and increasing systemic levels if significant absorption occurs.
  • Cimetidine: May inhibit lidocaine metabolism, increasing systemic levels if significant absorption occurs.
  • CYP3A4 inhibitors (e.g., macrolide antibiotics, azole antifungals, protease inhibitors): May increase lidocaine systemic levels if significant absorption occurs.
  • CYP1A2 inhibitors (e.g., fluvoxamine): May increase lidocaine systemic levels if significant absorption occurs.

Monitoring

📊

Routine Monitoring

Signs and symptoms of systemic toxicity (CNS, cardiovascular)

Frequency: During and immediately after application, especially with large areas, prolonged use, or compromised skin/mucosa.

Target: Absence of symptoms

Action Threshold: Any signs of dizziness, drowsiness, confusion, tremors, seizures, bradycardia, hypotension, or cardiac arrest require immediate medical attention.

đŸ‘ī¸

Symptom Monitoring

  • Local irritation (redness, swelling, itching, burning)
  • Allergic reactions (rash, hives, swelling, difficulty breathing)
  • CNS toxicity (dizziness, lightheadedness, drowsiness, confusion, disorientation, tinnitus, blurred vision, tremors, muscle twitching, seizures, slurred speech)
  • Cardiovascular toxicity (bradycardia, hypotension, cardiac arrest)
  • Methemoglobinemia (rare, but possible with high doses or prolonged use, especially in infants: cyanosis, shortness of breath, fatigue, rapid heart rate)

Special Patient Groups

🤰

Pregnancy

Lidocaine is considered Category B for topical use. Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women. Systemic absorption from topical application is generally low, minimizing fetal exposure.

Trimester-Specific Risks:

First Trimester: Low risk based on limited systemic absorption.
Second Trimester: Low risk based on limited systemic absorption.
Third Trimester: Low risk based on limited systemic absorption.
🤱

Lactation

Lidocaine is excreted into breast milk in small amounts. However, due to its low oral bioavailability and rapid metabolism, the amount transferred to the infant is generally considered clinically insignificant. It is rated L2 (likely compatible with breastfeeding).

Infant Risk: Low risk. Monitor infant for unusual drowsiness or feeding difficulties, though unlikely with typical topical use.
đŸ‘ļ

Pediatric Use

Use with extreme caution, especially in infants and young children, due to their higher surface area to body weight ratio, which can lead to increased systemic absorption and a higher risk of systemic toxicity (e.g., seizures, methemoglobinemia). Dosing must be carefully calculated based on weight and not exceed recommended maximums. Avoid use on large areas or broken skin.

👴

Geriatric Use

No specific dose adjustment is typically needed for topical lidocaine jelly. However, elderly patients may be more susceptible to systemic adverse effects if significant absorption occurs due to potential age-related decreases in hepatic function, cardiac output, and renal function. Use the lowest effective dose and monitor for signs of toxicity.

Clinical Information

💎

Clinical Pearls

  • Lidocaine jelly is primarily used for local anesthesia of mucous membranes (e.g., oral, pharyngeal, urethral, rectal) or for lubrication of instruments.
  • The 2% concentration is suitable for most mucous membrane applications. Higher concentrations (e.g., 5% patches) are typically for intact skin.
  • Instruct patients not to swallow the jelly, especially when used in the mouth/throat, as it can numb the gag reflex and lead to aspiration.
  • Be vigilant for signs of systemic toxicity (CNS and cardiovascular) if applied to large areas, broken skin, or used for prolonged periods, particularly in children or patients with liver impairment.
  • Methemoglobinemia is a rare but serious side effect, especially in infants, and should be considered if cyanosis unresponsive to oxygen occurs.
🔄

Alternative Therapies

  • Other local anesthetics (e.g., bupivacaine, ropivacaine - typically injectable)
  • Topical analgesics (e.g., diclofenac gel, capsaicin cream - different mechanisms)
  • Oral analgesics (e.g., NSAIDs, acetaminophen)
  • Cryotherapy (ice packs)
