In its basic form, lidocaine hydrochloride is a white powder without smell and with a bitter taste that is used both in human and veterinary medicine. The drug is also known as lignocaine hydrochloride, and is used as a local anesthetic and to regulate certain medical problems related to heart rhythm. Injections of it are used to provide local anesthesia during various minor surgical procedures. It is also available in various topical preparations, such as gels, sprays, creams, and ointments that are usually applied to the skin or the mucous membranes. This drug was first manufactured in Sweden in 1943 and was then named xylocaine.
When used for anesthetic purposes, lidocaine hydrochloride works by blocking certain functions of the nervous system, inhibiting the transmission of pain impulses from the treated area to the brain. It is a fast-acting form of local anesthesia that often starts to work within five minutes. The effects wear off in a relatively short time, often a couple of hours, because the drug is quickly metabolized by the liver.
Uses
This medication is used on the skin to stop itching and pain from certain skin conditions (e.g., scrapes, minor burns, eczema, insect bites) and to treat minor discomfort and itching caused by hemorrhoids and certain other problems of the genital/anal area (e.g., anal fissures, itching around the vagina/rectum). Some forms of this medication are also used to decrease discomfort or pain during certain medical procedures/exams (e.g., sigmoidoscopy, cystoscopy). Lidocaine is a local anesthetic that works by causing temporary numbness/loss of feeling in the skin and mucous membranes.
How to use lidocaine HCl topical
Before use on the skin, clean and dry the affected area as directed. Apply a thin layer of medication to the affected area of skin, usually 2 to 3 times a day or as directed.
