Lignocaine Hydrochloride
About Lignocaine Hydrochloride
Lignocaine Hydrochloride is a topical local anesthetic used to temporarily numb specific areas of the body to prevent or relieve pain. It is commonly used before minor medical procedures, needle insertions, or to soothe pain from minor skin irritations, small cuts, and abrasions.
The frequency and consistency of applying Lignocaine Hydrochloride depend entirely on your medical procedure or the nature of your discomfort, as directed by your healthcare provider. Because it is applied directly to the skin, food intake does not affect how this medication works. When using this product, keep the treated area clean and avoid scratching or rubbing the numbed skin to prevent accidental self-injury.
Most people tolerate this application well, but you may experience mild local reactions like temporary redness, pale skin, or a light tingling sensation. If you experience severe burning, swelling, or signs of systemic absorption such as dizziness, drowsiness, or a slow heart rate, seek medical attention immediately.
Do not use this medicine if you have a known allergy to similar numbing medications. Before starting, talk to your doctor or pharmacist if you have severe liver damage, heart rhythm issues, or if you need to apply it to large areas of broken or damaged skin.
While topical absorption is generally low, Lignocaine Hydrochloride may interact with certain heart medications or other local anesthetics. If you are pregnant, breastfeeding, or caring for an elderly patient, talk to your doctor or pharmacist before using this medication to ensure it is safe for your specific situation.
Lignocaine Hydrochloride is available in several topical formulations, including gels, creams, ointments, sprays, and solutions. Your doctor or pharmacist can help you choose the formulation that is most suitable for your condition.
Uses of Lignocaine Hydrochloride
Medicinal Benefits
When used as directed as part of your treatment plan, this medicine may provide the following benefits:
- Rapid Pain Relief: Lignocaine Hydrochloride provides rapid, localised pain relief by temporarily desensitising the nerve endings in the specific area where it is applied. This targeted action ensures that you do not feel discomfort during minor medical procedures or while healing from superficial skin irritations.
- Pain-Free Procedures: By numbing only the surface area, it prevents the need for systemic pain medications, thereby reducing the risk of widespread side effects. It allows patients to undergo necessary clinical tests, needle insertions, or minor dermatological treatments with minimal anxiety and pain-free comfort.

- Apply a thin layer of Lignocaine Hydrochloride to the affected area and gently rub it in.

Disease/Condition Glossary
Pain: Pain alerts your nervous system that something is amiss. It is a painful sensation such as a prick, tingling, sting, burn, or aching. Pain can be either acute or dull. It might come and go or be continuous. You may have pain in one part of your body, such as your back, abdomen, chest, or pelvis, or you may experience pain throughout your body. Pain can be generalised (overall body aches) or localised (affecting a specific body area).
Local anaesthesia: It causes numbing/loss of sensation to a specific area of the body. It is used to treat or prevent pain during surgery or medical procedures.
Post-herpetic neuralgia: Post-herpetic neuralgia is a persistent discomfort associated with shingles. Shingle is a viral illness that causes painful rashes caused by the recurrence of chicken pox virus infection. Symptoms include nerve discomfort and itching.
FAQs
Lignocaine Hydrochloride is used for local anaesthesia.
Lignocaine Hydrochloride blocks the influx of sodium ions into the membrane that surrounds the nerves, thereby preventing the initiation and conduction of impulses (nerve signal). Hence, it provides an anaesthetic effect and decreases the sensation of pain.
Avoid using Lignocaine Hydrochloride with other topical products such as cosmetics, sunscreens, lotions, moisturizers, insect-repellent creams, and other gels.
Do not apply external heat or cover the treated skin with dressings after applying Lignocaine Hydrochloride. Covering the skin or applying heat might increase the amount of drug absorbed into the skin, leading to unpleasant side effects.
Do not apply Lignocaine Hydrochloride on open wounds, injured skin, or unhealed shingles blisters. Apply Lignocaine Hydrochloride on intact skin only.
Avoid using Lignocaine Hydrochloride for longer durations unless prescribed by the doctor. If your condition does not improve even after using Lignocaine Hydrochloride for seven days, consult your doctor.
Yes, it can be used to temporarily relieve the pain of minor sunburns, but do not apply it to severely blistered or broken skin. Talk to your doctor for advice on severe burns.
Rinse your eyes thoroughly with cool, clean water right away. If you experience persistent irritation or changes in your vision, seek medical attention immediately.
It should only be used during pregnancy if the potential benefits outweigh the risks. Talk to your doctor or pharmacist before using this product if you are pregnant.
Lignocaine Hydrochloride should only be used in children under the guidance of a doctor or healthcare professional. Children are more sensitive to local anesthetics, and using too much or applying it over large areas can increase the risk of serious side effects. Always follow the recommended dose and instructions for your child's age.
Numbing of the mouth and throat can impair your ability to swallow safely and increase the risk of choking or biting your tongue and inner cheeks. Avoid eating or drinking until the numbness completely wears off.
The numbing sensation usually lasts for about 30 to 60 minutes after application, depending on the area treated and the amount used. Talk to your doctor if you have concerns about prolonged numbness.
