Lignocaine Spray

Lignocaine (also spelled Lidocaine) is a well-known local anesthetic that is available in various forms, including a topical spray. It works by numbing the area where it is applied, temporarily blocking nerve signals that send pain messages to the brain.

Key Information:

• Active Ingredient: Lignocaine (Lidocaine).

• Drug Class: Local Anesthetic.

• Uses: Lignocaine spray is used to provide temporary pain relief and numbing for a variety of conditions and procedures. Common uses include:

  • Medical and Dental Procedures: It can be used to numb mucous membranes in the mouth, throat, and respiratory tract to reduce pain and gag reflex during procedures like dental impressions, intubation, endoscopy, or examinations.

  • Minor Skin Irritations: It can provide relief from pain and itching caused by minor burns (including sunburn), scrapes, insect bites, or other minor skin irritations.

• Important Note: Lignocaine spray is for external or topical use only. It should not be inhaled or ingested. It is also important to note that different concentrations of lignocaine spray are used for different purposes, and its use should be guided by a healthcare professional.

Dosage and Administration:

• The dosage of lignocaine spray depends on the concentration of the product and the specific condition or procedure.

• Each spray from a metered-dose device typically contains a specific amount of lignocaine (e.g., 10 mg per spray).

• The spray is applied directly to the affected area.

• It is crucial to follow the instructions on the product label or as directed by a healthcare professional to avoid using an excessive amount, which can lead to serious side effects.

• Avoid spraying near the eyes and do not use on large areas of broken, irritated, or swollen skin.

Common Side Effects:

• Mild skin irritation, redness, or dryness at the application site.

• Stinging or burning sensation.

• Mild nausea.

Serious Side Effects and Warnings:

• Systemic Toxicity: Using too much lignocaine or applying it to large, raw, or broken skin areas can lead to the drug being absorbed into the bloodstream. This can cause serious side effects affecting the central nervous system (CNS) and heart. Symptoms of toxicity can include:

  • Dizziness, drowsiness, or confusion.

  • Tremors or seizures.

  • Numbness or tingling around the mouth.

  • Slow or irregular heartbeat.

  • Shortness of breath.

• Allergic Reactions: While rare, a severe allergic reaction (anaphylaxis) is possible, especially in people with known allergies to lignocaine or other local anesthetics. Symptoms can include a rash, hives, swelling of the face, lips, tongue, or throat, and difficulty breathing. Seek immediate medical attention if these symptoms occur.

• Use in the Mouth/Throat: When used in the mouth or throat, the numbing effect can make swallowing difficult and increase the risk of choking. Do not eat or drink for at least one hour after use in these areas.

• Flammability: Lignocaine sprays often contain alcohol and are flammable. Do not use near an open flame or while smoking.
