Lidocaine spray is a topical anesthetic designed to temporarily numb a specific area of the body’s surface. It works by blocking nerve signals in the skin, which helps reduce sensations like pain and discomfort. This spray format allows for targeted application, making it a convenient option for temporary relief. Its purpose is to provide localized numbing without affecting the entire body.
Preparing for Application
Before using lidocaine spray, carefully read the product’s instructions for specific guidance. Always check the expiration date on the packaging to ensure the product is still effective and safe to use. You should clean the area where the spray will be applied, ensuring it is dry to allow for proper absorption.
Performing a patch test is a recommended step, especially for first-time users or when applying to a new area. Apply a small amount of the spray to an inconspicuous area of skin and observe for any adverse reactions, such as excessive redness, itching, or irritation. This helps determine individual sensitivity before widespread application.
Applying the Spray
Applying lidocaine spray requires attention to detail for effective numbing. Shake the can well before use to ensure active ingredients are evenly mixed for consistent delivery. Hold the can upright, 6 to 12 inches (15 to 30 cm) from the skin, or as directed by product instructions.
When spraying, use short, controlled bursts rather than a continuous stream. This technique helps achieve even coverage and prevents over-application in one spot, which can happen with a prolonged spray. Move the can across the target area to ensure uniform distribution. The product typically dries within a minute and does not need to be rubbed in, which helps prevent irritation and ensures proper absorption.
A cooling sensation will occur immediately upon application, followed by numbness within a few minutes. The numbing effect usually becomes noticeable within 1 to 5 minutes and can persist for 10 to 30 minutes, depending on the product’s concentration and the area treated. After application, it is important to wash your hands thoroughly with soap and water to remove any residual product and prevent accidental contact with sensitive areas.
Safety Precautions and Storage
Observe several precautions when using lidocaine spray to ensure safety. Use the product only as directed on the label, avoiding exceeding the recommended dosage or frequency. Applying too much or too frequently can lead to increased absorption into the bloodstream, potentially raising the risk of systemic side effects.
Avoid spraying lidocaine directly into the eyes, nose, mouth, or onto other mucous membranes, as this can cause irritation or other complications. Do not apply the spray to broken, irritated, or damaged skin, including open wounds, rashes, or severe burns. Skin that is compromised can absorb a significantly higher amount of the medication, increasing the risk of adverse effects. Avoid covering the treated area with bandages, plastic wrap, or applying local heat (like heating pads), as these can enhance absorption and lead to higher-than-intended drug levels.
Proper storage of lidocaine spray maintains effectiveness and ensures safety. Store the container at room temperature, generally below 25°C (77°F), away from excessive heat, moisture, and direct sunlight. Many lidocaine sprays are flammable due to their propellant, so they must be kept away from open flames, sparks, and heated surfaces. Never puncture or incinerate the container, and avoid storing it at temperatures above 120°F (49°C), as contents are under pressure. Always keep the product securely out of the reach of children and pets to prevent accidental ingestion or misuse.
When to Contact a Professional
Seek medical advice for concerning reactions after using lidocaine spray. Contact a healthcare professional if symptoms worsen, redness or irritation develops, or symptoms persist for more than 7 days.
You should also consult a doctor if the spray does not provide the expected numbing effect or if the numbness does not subside within a reasonable timeframe. Seek immediate medical attention if you experience severe side effects such as difficulty breathing, swelling of the face, lips, or tongue, unusual dizziness, confusion, or a rapid heartbeat, as these could indicate a serious reaction.
