Lidocaine is an anesthetic drug that works by inhibiting the transmission of pain signals to the brain through nerves in the skin. Because of this, almost all possible applications of lidocaine serve to control pain in many areas of the body.

Sprays, casts, gels, ointments, injections, lozenges, and other versions of lidocaine serve to relieve localized pain. The type of application varies depending on the location and type of injury or inflammation. An advantage of lidocaine pain therapy is its rapid action, but lidocaine has other health benefits, as can be seen below.

What is lidocaine

Lidocaine is a local anesthetic, frequently used due to its efficacy and rapid action against pain. Its anesthetic effect begins after a few minutes and can last for several hours.

This medicine corresponds to the type of amides, it can be used externally to anesthetize specific areas of the skin. Some versions can be administered internally, in addition, it has a calming effect on the cardiovascular system in cases of tachycardias and cardiac arrhythmias.

What is lidocaine for

Products that contain lidocaine are used to numb the skin and some internal areas. For this reason it is used, among other things, to:

Lidocaine for medical interventions

It can be used, for example, in treating wounds or administering an infusion.

Lidocaine is used to numb the skin

In cases where the placement of piercing, earrings or tattoos is required.

Lidocaine to calm hemorrhoid symptoms

This medicine is perfect for soothing annoying aches like hemorrhoids, itchy and painful bumps around the anus. Lidocaine can be used in different dosage forms to treat pain caused by this condition. One possibility is the administration of suppositories, another is in the form of an ointment. There are also a few types of lidocaine impregnated tampons recommended for this treatment.

It is important that all dosage forms are used correctly. Also, it should be noted that lidocaine can only relieve pain and does not cure hemorrhoidal diseases.

Lidocaine for insect bites

Other intense pain such as the sting of wasps, spiders, scorpions, etc. they can also be calmed with lidocaine.

Lidocaine to control premature ejaculation

In some cases, men also use ointments such as lidocaine to numb the skin and thus prevent premature ejaculation. The active ingredient in lidocaine makes the glans less susceptible to stimuli, thus helping to delay ejaculation.

Lidocaine is used to depilate

Because lidocaine temporarily numbs the area where it was applied, it is often used for hair removal treatments. Although the action of this drug inhibits the sensation of pain, this does not mean that certain treatments can cause injuries.

Lidocaine for toothache

Perhaps one of the best known uses of lidocaine is its application in dental treatments, mainly to soothe a terrible toothache.

Lidocaine to relieve canker sore pain

The analgesic and anesthetic effect of lidocaine is also used in cases of painful canker sores that come out in the mouth. Lidocaine as a mouthwash is used for inflammatory diseases of the oral mucosa, such as mucositis.

These inflammations of the oral mucosa occur mainly in patients undergoing chemotherapy or radiation. Lidocaine helps relieve pain and promotes mucosal healing. The effect lasts only half an hour, therefore, it is used frequently so that the patient can eat without pain.

Lidocaine serves as an antiarrhythmic

There are sodium channels in the heart that are important for heart rate and rhythm. When lidocaine blocks these channels in the heart, the heartbeat slows down and the rhythm can normalize. For this reason, lidocaine is also used for cardiac arrhythmia.

Lidocaine for migraine

In cases of migraine, the local application of lidocaine through a nasal tube can stop the acute attack. It even serves to prevent further attacks in the days after. This occurs because a nerve nodule in the area of ​​the nasal root, the so-called pterygopalatine ganglion, is anesthetized.

This anesthetic works longer than other medications, as the nerve node is a kind of reset button for migraine. Therefore, circulation is instantly cut off and migraine attacks become less frequent. However, this is only a palliative therapy for migraine and not a cure.

Lidocaine for scar pain

Lidocaine can also be used for scar pain. After some operations, painful scars can form, for example, after mastectomies, operations on the heart, kidneys or lungs, and after hernia operations.

This pain is usually caused by a nerve ending that was damaged or is pressed by the scar. Scar pain is constantly felt and worse when there is superficial contact. Lidocaine temporarily anesthetizes the scar, so the pain decreases.

How lidocaine works

Stimuli such as pressure or temperature are sensed by a variety of nerve endings that transmit this signal to the spinal cord or brain. Thus, a certain stimulus can be perceived as pain. This transfer is done with the help of minerals such as potassium and sodium.

Lidocaine influences sodium channels and therefore prevents the transmission of the stimulus. Thus, by the time lidocaine acts, the pain cannot be perceived, as the area becomes numb.

Lidocaine presentation

Lidocaine is well absorbed through the mucous membrane. This is the reason why this active ingredient usually comes in the form of ointments and sprays. But it can also be administered as injections, pills, and suppositories.

Lidocaine ointment or cream

Lidocaine is used as a cream, ointment, or paste for pain, itching, or burning. This use is quite frequent in people who carry out sports activities and are exposed to suffering blows. Lidocaine cream is also used as part of the treatment for hemorrhoids.

Lidocaine gel

As a medical gel, it is mainly used to make treatments in the body cavities less painful. For example, the insertion of catheters or breathing tubes and endoscopies.

Lidocaine spray

Lidocaine spray is used for the external treatment of pain, applying directly to the affected area. It is also recommended for the treatment of inflammations within the oral cavity.

Injectable lidocaine

As an injection, lidocaine works as an anesthetic for certain regions of the body. Lidocaine injections should only be given to healthy skin and by people trained to give them.

Lidocaine in suppositories

As suppositories, lidocaine is specifically recommended for hemorrhoid treatments, both in children and adults.

Lidocaine lozenge
