Lidocaine: Frequently Asked Questions Answered
What is lidocaine?
Lidocaine is an anesthetic medication used for inducing loss of sensation in different parts of the body, skin, and surrounding tissues. The medicine is available as a topical jelly, patch, liquid, or ointment. After application, it numbs a body part, alleviates pain, or reduces itching.
Also known as lignocaine, it is a safe local anesthetic of the amino amide-type. It is an essential medicine, as recommended by the World Health Organization.
What are the uses of lidocaine?
Lidocaine is available only with a doctor’s prescription. It helps relieve pain by blocking the signals at the nerve endings in the affected area.
Lidocaine relieves pain from sunburn, minor cuts, insect stings or cuts, and urethritis. One of its uses as a topical solution is to potentially treat sore throat or mouth.
Shingles are a painful rash caused by the chickenpox (herpes zoster) virus. Nerve pain may persist even after the rash disappears as post-herpetic neuralgia. Lidocaine skin patches provide relief from post-herpetic neuralgia.
Some doctors use lidocaine to reduce gagging while taking dental impressions or an X-ray.
