Spray "Lidocaine" is a drug with a local anesthetic effect. It is used to anesthetize mucous membranes in medical practice in the field of dentistry and surgery.
The composition of this drug
According to the instructions, the spray "Lidocaine" is made in the form of a colorless transparent liquid with a specific menthol odor. The active substance is lidocaine, which is part of the group of anesthetics. One dose of the spray contains 4.8 mg of lidocaine. In addition to the main component, the composition of the drug is supplemented with auxiliary substances such as peppermint oil, propylene glycol and ethanol.
One bottle contains 650 doses of the drug. In the package, in addition to the bottle itself, there is a special dispensing nozzle and instructions.
Properties of the drug
Lidocaine is a derivative of acetanilide. The substance is able to reduce the susceptibility of nerve endings by inhibiting the generation and conduction of an impulse through the nerves. In addition, lidocaine allows you to stabilize the neurocyte membrane for sodium ions, thereby increasing the threshold of electroexcitation.
The substance has a systemic effect on the body and has an antiarrhythmic property. When using therapeutic dosages of the drug, Lidocaine allows you to adjust the heart rate.
On sale you can find throat sprays with lidocaine. When applying the product to the mucous tissues of the respiratory tract, there is a suppression of the emetic and cough reflexes, thus aspiration bronchopneumonia is prevented.
Spray "Lidocaine" is intended for topical use. The active component of the drug enters the systemic circulation. The intensity of absorption directly depends on the location and area on which the drug is used.

How to use Lidocaine spray?
Instructions for use
The medication is applied directly to the place where pain relief is required. The bottle must be kept upright. To achieve an optimal analgesic effect, it is necessary to carry out up to five sprays of the drug. If we are talking about a wider area for pain relief, a dosage increase of up to 15-20 sprays is allowed.
When used in children, a gauze dressing can be used, on which a spray is previously applied, and then applied to the required area of the body. In the presence of liver and kidney failure, a dosage change is required to decrease by half.
Before applying the drug, a specialist must ask about the presence of an allergy to lidocaine. It is important to inform that if a reaction to this substance has ever been observed, in order to avoid undesirable consequences, the use of the drug should be abandoned.
Adverse reactions
When using Lidocaine, undesirable local reactions may occur, for example, burning and redness of mucous tissues and skin. As a rule, after the onset of anesthesia, negative symptoms disappear. An allergic reaction to lidocaine is characterized by itching and a rash on the skin, in exceptional cases anaphylactic shock can occur.
The nervous system may respond to the use of the drug by severe patient anxiety. From the side of the heart and blood vessels, bradycardia and arterial hypotension are possible.
Significant excesses of the prescribed dosages of the drug can lead to the development of convulsive syndrome, as well as negative consequences on the part of blood vessels and the heart. An overdose is treated by eliminating the symptoms that have arisen. There is no specific antidote for Lidocaine.
Spray "Lidocaine" for men
One of the unofficial areas of application of the drug in the form of a spray is the genital area in men. The drug can be used to prolong sexual intercourse. A similar remedy may be required in case of premature ejaculation or a duration of sexual intercourse of less than one minute.
Lidocaine spray is sprayed to extend the act at a distance of ten centimeters fifteen minutes before the start of the process. It acts quite quickly, two minutes after application, the application is “frozen”. To prolong sexual intercourse, 5 mg of lidocaine is used, which is 1-2 sprays. It is not recommended to exceed this dosage, as this can provoke the appearance of adverse reactions.
With this method of use, a number of limitations should be considered. So, you can not use a spray if a man has an allergy to lidocaine. The drug is also contraindicated in diseases of the cardiovascular system and pathologies of the liver or kidneys in a chronic form of the course.
Adverse reactions with this method of using the drug are similar to the cases described above.

- The effectiveness of the drug decreases over time.
Recommendations
When using Lidocaine in the form of a spray, the following recommendations should be followed:
- Before the first use, it is necessary to conduct a sensitivity test by putting the drug on the arm. If there is no irritation, then you can use the spray on other parts of the body.
- It is poorly compatible with drugs that include iodine.
This is confirmed by the instructions for use with Lidocaine spray.

- "Luan."
- Dinexan.
- "Helikain."
- "Lidocaine hydrochloride."
- Lidocaine Vial.
- "Lidocaine bufus."
- Versatis.
- Xylocaine.
- "Ultracaine" is also an analogue of the drug, but is less toxic than "Lidocaine". "Ultracain" provides a longer analgesic effect.
Many are also interested in the difference between Lidocaine and Novocaine. The latter shows a more moderate anesthetic effect, while Lidocaine is considered a more effective pain medication.
What patients say
Reviews about the spray "Lidocaine" are mostly positive. Women often use a spray to anesthetize the skin during the hair removal procedure. The drug copes well with its tasks, although many note its effectiveness in cases when it comes to moderate pain. If we are talking about a high degree of intensity of the pain syndrome, the drug is far from always effective.
The cost of the spray is also its undoubted advantage for consumers. The price of the drug averages 250 rubles. Given that the spray is enough for a long period of use, the cost of "Lidocaine" is characterized as low.
The only drawback is called adverse reactions, especially local ones that occur when applying the spray.
Men who use the drug to prolong sexual intercourse also leave mostly positive reviews about the effect of the drug. However, some felt an unpleasant burning sensation directly when applying Lidocaine. A disadvantage is the need to use a condom after applying the drug to avoid getting lidocaine in the woman's vagina.
