What is Lidocaine Spray 10%?

Lidocaine Spray 10% is a topical anesthetic created to provide fast and controlled numbing of mucous membranes during short procedures. It works by temporarily reducing sensitivity in targeted areas, helping make examinations or interventions involving the mouth, nose, throat, airway, or reproductive tract more comfortable. The spray activates within minutes and is suitable for adults and children from 2 years of age when applied as directed. Its concentrated formula delivers predictable, surface-level anesthesia that supports smoother clinical experiences for brief, localized procedures.

The numbing effect typically lasts 10–15 minutes, offering adequate time for many routine diagnostic or procedural tasks. Its clear, lightly menthol-scented solution applies easily to the intended site, and proper dosing allows safe and consistent use. Because absorption varies depending on the mucosal surface, correct technique ensures reliable results and minimizes the risk of excessive systemic uptake. Lidocaine Spray 10% is intended exclusively for external use on mucous membranes and provides efficient, short-lasting anesthesia when used appropriately.

What is Lidocaine Spray 10% used for?

Lidocaine Spray 10% is used when rapid and effective surface anesthesia of mucous membranes is required. It is suitable for adults and children aged 2 years and older during procedures such as dental preparation, oral or nasal examinations, gastrointestinal endoscopy preparation, airway instrument placement, and certain obstetric or gynecological manipulations. Its quick onset supports short clinical procedures that benefit from a brief numbing effect.

Who should not use Lidocaine Spray 10%?

The spray should not be used by individuals with known hypersensitivity to lidocaine or other amide-type anesthetics. It is also unsuitable in cases of shock or significant conduction block. The product must not come into contact with the eyes; accidental exposure requires immediate rinsing with water. Lidocaine Spray 10% should not be applied to endotracheal tube cuffs due to the risk of material damage and air leakage.

What precautions should be taken before using Lidocaine Spray 10%?

Only the lowest effective dose should be used to prevent unnecessary systemic absorption. Absorption through mucous membranes varies, and areas such as the bronchial tree may allow higher uptake. Excessive doses or short dosing intervals may increase the risk of unwanted effects. Caution is advised when applying the spray to damaged or irritated mucous membranes, as absorption may be enhanced.

Additional attention is needed for patients with cardiovascular disease, heart block, epilepsy, liver impairment, kidney impairment, or those in weakened general condition. When applied to the oropharynx, temporary numbness may interfere with swallowing, increasing the risk of biting or aspiration.

Can Lidocaine Spray 10% interact with other medicines?

High doses may increase the risk of systemic toxicity when combined with other local anesthetics or structurally related medicines. Medicines that reduce lidocaine clearance may elevate plasma levels during prolonged or repeated use. Caution is recommended when using the spray with class III antiarrhythmic agents due to the potential for additive cardiac effects.

Is Lidocaine Spray 10% safe during pregnancy or breastfeeding?

Available data show no developmental risks when lidocaine is used during pregnancy. Only small amounts enter breast milk, and no effects on breastfed infants are expected at therapeutic doses. The spray may be used during pregnancy or breastfeeding when clinically necessary.

How should Lidocaine Spray 10% be used?

The spray provides anesthesia within 1–3 minutes and lasts approximately 10–15 minutes. Dosage should be chosen based on the procedure and the patient’s condition. For children, weight-based adjustments are required, and maximum limits should not be exceeded. The spray must not be used on endotracheal tube cuffs. Proper technique and close attention to dosing intervals ensure predictable and safe results.

What happens if too much Lidocaine Spray 10% is used?

Overdose may result in systemic toxicity affecting the nervous and cardiovascular systems. Early symptoms can include tingling, dizziness, hearing disturbances, or tremors, potentially progressing to seizures or loss of consciousness. Severe cases may lead to respiratory depression or cardiac complications. Treatment usually includes airway support, oxygen therapy, and measures aimed at stabilizing the patient.

What side effects can occur with Lidocaine Spray 10%?

Side effects are uncommon and typically linked to high doses or rapid absorption. Possible reactions include nervous system symptoms such as restlessness, drowsiness, tremor, or visual disturbances. Cardiovascular effects like hypotension or changes in heart rhythm may also occur. Mild, temporary local irritation can appear on the application site, especially after airway-related procedures.

What does Lidocaine Spray 10% contain?

Each bottle contains lidocaine as the active ingredient, along with peppermint oil, propylene glycol, and ethanol.

The solution is clear and colorless to slightly yellow, with a characteristic menthol-ethanol aroma.

How should Lidocaine Spray 10% be stored?

Store the spray in a light-protected place at 15°C to 25°C (59°F to 77°F). Keep out of reach of children and do not use after the expiration date.
