Lidocaine is a local anesthetic agent commonly used for local and topic anesthesia, but it also has antiarrhythmic, and analgesic uses and can be used as an adjunct to tracheal intubation.

Intravenous lidocaine is used broadly in the management of neuropathic pain, postoperative pain, postherpetic neuralgia, centrally mediated pain, headache and infiltrative malignant neurological lesions (8). Lidocaine is a relatively safe drug, which can be used at low doses without any notable safety concerns.

Using lidocaine skin cream before a procedure will ease any pain at the site of the procedure, such as pain from a needle being used to take blood. How long does it take to work? Lidocaine cream works quite quickly. Most people will start to feel a numbing effect within 30 to 60 minutes.

Adults - Apply to the affected area 3 or 4 times a day. The largest amount of ointment that should be used in a single application is 5 grams. If you use the 5% ointment, this is about 6 inches of ointment from the tube. Children - Dose is based on body weight and must be determined by your doctor.

Applied either by injection, inhalation, or as a topical agent to provide anesthesia, lidocaine has a good safety margin before reaching toxic blood levels. Since it can be applied in various forms to the same patients, however, care must be taken to keep track of the total dose given to minimize its systemic toxicity.

Lidocaine can cause serious side effects, especially in children, if it gets into the mouth and is swallowed. If you are using the viscous topical solution medicine in the mouth or throat, be aware of signs of toxicity.

Generally, lidocaine cream works within 30 minutes and may last for up to 3 hours. Both the lidocaine patch and lidocaine cream can be used to treat backaches, muscle soreness, mild joint pain, itching, and nerve pain.

When used sparingly and as directed, topical lidocaine is generally safe. However, misuse, overuse, or overdose can lead to a number of serious health problems and even death. Ingestion of lidocaine can cause numbness of the mouth and throat, which can lead to trouble swallowing and even choking.

Adults - Apply 1 to 2.5 grams (g) in a thick layer to the skin area. The size of the area to be covered and the length of time the medicine is kept in place will depend on the procedure. Cover the area with a bandage. The medicine may need to stay on the skin for up to 2 hours.

Lidocaine topical lotion is an anesthetic that treats the symptoms of several conditions, like eczema, minor burns, scrapes, insect bites and hemorrhoids. This medication causes a loss of feeling in your skin and the surrounding tissues to relieve itching, pain and discomfort.

When used sparingly and as directed, topical lidocaine is generally safe. Misuse, overuse, or overdose can cause serious problems and even death.

Sensory complaints may include tinnitus and blurred vision. Excitatory signs, such as restlessness, agitation, nervousness, or paranoia, may progress to muscle twitches and seizures. Ultimately, with large overdoses, CNS depression, including unconsciousness and coma, can occur.

Ester local anesthetics and carbonated lidocaine produce widespread and severe damage of the nerve fibers and the blood-nerve barriers when injected within the fascicles.

The most common adverse events were administration site reactions: burning, dermatitis, erythema, pruritus, rash, skin irritation, and vesicles.

Background: Many studies have demonstrated that lidocaine directly relaxes airway smooth muscle. The underlying mechanisms, especially in relation to Ca2+ mobilization, remain to be elucidated.
