Lidokain Spay instructions for use, how to take?
What is HOW TO TAKE LIDOCAINE?
HOW TO TAKE LIDOCAINE is an informational and practical material accompanying preparations based on lidocaine hydrochloride, which belongs to the group of amide-type local anesthetics. Lidocaine blocks the conduction of pain impulses along the nerve fiber, temporarily reducing the sensitivity of the skin and mucous membranes in the area of application or administration. The pharmacological group defines it as an agent for local (topical, infiltration, conduction) anesthesia, as well as an class IB antiarrhythmic drug for intravenous use under special indications. This is why the instructions on HOW TO TAKE LIDOCAINE provide for a clear distinction between dosage forms and routes of administration, as an error here directly affects safety.
The dosage forms covered by HOW TO TAKE LIDOCAINE are diverse: injection solution of various concentrations, spray dispenser for spraying mucous membranes, gel, cream, ointment, as well as transdermal patches. In the category of intimate products, which conventionally includes products like "Female Viagra", lidocaine is most often found in the form of prolonged-action sprays and creams that reduce excessive sensitivity. The manufacturer of a specific brand name is indicated on the package and in the leaflet, so before use, you should check the concentration of the active substance and the expiration date. Different manufacturers may use different bases — water-alcohol, gel or fat — and this affects the rate of onset of the effect.
The popularity of lidocaine is explained by the combination of a rapid onset of action, predictable duration of pain relief and extensive clinical experience in dentistry, surgery, dermatology, gynecology and urology. The effect after application to the mucous membrane usually develops within 1–5 minutes, after infiltration administration — almost immediately, and lasts from 30 to 120 minutes, depending on the dose and the presence of vasoconstrictor additives. The material HOW TO TAKE LIDOCAINE does not replace the official instructions and is not a recommendation for self-treatment. Before the first use, a consultation with a doctor is mandatory, who will assess the appropriateness, select the form and concentration.
What is HOW TO TAKE LIDOCAINE prescribed for?
The main indication described by HOW TO TAKE LIDOCAINE is local anesthesia before medical manipulations. This includes dental interventions, suturing and suture removal, incision of small abscesses, punctures, urinary bladder catheterization, gastroscopy and bronchoscopy, where the spray reduces the gag reflex. In dermatology and cosmetology, gel or cream is used before laser procedures, hair removal, mesotherapy and tattooing. This approach allows the procedure to be performed comfortably, without systemic anesthesia and its associated risks.
The second large block of indications is symptomatic relief of pain and hypersensitivity. Gels with lidocaine are used for painful teething in adults, stomatitis, fissures, hemorrhoids, superficial burns and insect bites. In the field of intimate health, products with lidocaine are used to reduce excessive sensitivity of the mucous membranes, which helps to prolong the duration of sexual intercourse; that is why such sprays fall into the category along with products like "Female Viagra", although their mechanism of action is fundamentally different — anesthetic, not stimulant. It is important to understand this difference so as not to expect an uncharacteristic effect from the drug.
Separately, the instructions on HOW TO TAKE LIDOCAINE mention cardiological use — management of ventricular arrhythmias in hospital settings under ECG monitoring. This is an exclusively medical competence, and any independent use of the injection solution for this purpose is unacceptable. Lidocaine is also part of combination products for the treatment of neuralgia and myofascial pain in the form of patches. The choice of indication always remains with the specialist, since pain can be a symptom of a condition that requires etiological rather than analgesic treatment.
Composition and active ingredients of HOW TO TAKE LIDOCAINE
The active substance is lidocaine hydrochloride, the concentration of which varies: 1%, 2% or 10% in solutions, 2–5% in gels and ointments, approximately 10 mg per dose in sprays. The mechanism of action consists in the reversible blockade of sodium channels of the nerve fiber membrane: without the entry of sodium ions, an action potential is not formed, and the pain signal does not reach the brain. First, the sensation of pain and temperature disappears, then tactile sensitivity, while motor function during topical application is usually preserved. The effect is completely reversible and disappears as the substance is absorbed and metabolized in the liver.
Excipients depend on the form. In sprays, these are ethanol, propylene glycol, peppermint oil or levomenthol, which provide a cooling sensation and facilitate distribution. Gels use carbomers, glycerin, methylparaben as a preservative, and purified water; ointments use vaseline, lanolin, paraffin, which form a film and prolong contact with tissues. Injection solutions contain sodium chloride for isotonicity and sometimes sodium hydroxide for pH adjustment.
Some forms additionally contain epinephrine (adrenaline), which constricts blood vessels, slows down the absorption of the anesthetic, thereby prolonging the action and reducing the risk of systemic toxicity. Such combinations have more limitations and are not used in areas of terminal blood supply. The presence of parabens, menthol or ethanol can provoke allergic reactions and irritation, so patients with a tendency to allergies should carefully study the list of components.
Dosage of HOW TO TAKE LIDOCAINE
For adults, when using the spray, the standard recommendation is 1 to 3 sprays per area, while the maximum single dose should not exceed 200 mg of lidocaine (approximately 20 doses of the spray) for a healthy person of average weight. Gel or cream is applied in a thin layer to the area limited by the intervention zone, usually 1–2 g per procedure. The frequency of application is no more than 3–4 times a day with an interval of at least 4 hours. The duration of the course for symptomatic use should not exceed several days without reassessment by a doctor.
Dose adjustment is mandatory for patients with hepatic or heart failure, since lidocaine metabolism occurs mainly in the liver and depends on hepatic blood flow. For elderly people, debilitated patients and individuals with low body weight, the dose is reduced by about a third. For children, the drug is prescribed exclusively by a doctor based on kilograms of body weight, usually no more than 3–4 mg/kg. Exceeding the dose significantly increases the risk of systemic toxicity.
How to take HOW TO TAKE LIDOCAINE correctly?
Before application, the skin or mucous membrane should be cleaned and dried, as excess moisture dilutes the preparation and reduces the effect. The spray is sprayed from a distance of approximately 2–5 cm, holding the bottle vertically and avoiding inhalation of the aerosol; the gel is distributed evenly with a gloved fingertip or applicator. The effect develops in 1–5 minutes, so the procedure is started only after numbness occurs. Do not apply the product to open wounds, inflamed or damaged skin without a doctor's prescription, as absorption increases sharply.
The connection with food intake is relevant only for forms used in the oral cavity and throat: after treating the mucous membrane, one should refrain from food and drinks for at least 1–2 hours, until the swallowing reflex is restored. Since lidocaine in these forms is not taken systemically on a schedule, the concept of a "missed dose" is almost not applicable — the drug is used situationally, as needed. If the planned procedure was postponed, re-application is done no earlier than after 4 hours. When using intimate sprays, it is recommended to wash off the remains of the product before contact to avoid transferring anesthesia to the partner.
Before the first full use, it is advisable to conduct a test: apply a small amount to a limited area and evaluate the reaction within 15–30 minutes. The individual reaction of the body can vary significantly — from the absence of a noticeable effect to pronounced numbness and redness. You should not combine several forms of lidocaine at the same time to avoid exceeding the total dose. Any unusual sensations are a reason to stop use and consult a specialist.
Side effects of HOW TO TAKE LIDOCAINE
The most common are local reactions: burning, tingling, redness, temporary paleness of the skin and a sensation of swelling in the area of application. Usually, they disappear on their own within 10–30 minutes and do not require treatment. Sometimes patients note a metallic taste in the mouth or numbness of the tongue when treating mucous membranes. Such manifestations are expected pharmacological effects, not a sign of intolerance.
Uncommon side effects are associated with systemic absorption: dizziness, drowsiness, headache, tinnitus, blurred vision, anxiety, nausea. Less commonly, decrease in blood pressure, bradycardia, heart rhythm disturbances, tremors and muscle twitching occur. The most severe, but rare reactions are convulsions, respiratory depression, anaphylactic shock and methemoglobinemia, manifested by cyanosis of the skin and shortness of breath.
Immediate medical attention is required for: increasing dizziness with impaired consciousness, convulsions, severe shortness of breath, swelling of the lips and throat, rash spreading over the body, sudden weakness or a feeling of heart palpitations. In such cases, the use of the drug is stopped, the remains are washed off with water, and the patient is placed in a horizontal position until the arrival of a doctor. Any alarming symptoms should be discussed with a specialist, even if they seem minor.
Contraindications of HOW TO TAKE LIDOCAINE
Absolute contraindications are hypersensitivity to lidocaine and other amide-type anesthetics, severe sinoatrial and atrioventricular block without a pacemaker, sick sinus syndrome, cardiogenic shock, severe arterial hypotension and severe heart failure. The drug is not used in porphyria, as well as on large areas of damaged or infected skin. Injectable forms are prohibited in case of known allergy to preservatives in the solution.
Relative contraindications include liver and kidney failure, epilepsy, myasthenia gravis, bradycardia, hypovolemia, as well as old age and exhaustion. During pregnancy, lidocaine is used only under clear indications, when the expected benefit to the mother outweighs the potential risk to the fetus; during lactation, a pause in breastfeeding is advisable after use. For young children, topical forms are prescribed exclusively by a pediatrician, as their risk of methemoglobinemia is higher.
Interaction of HOW TO TAKE LIDOCAINE with other drugs and alcohol
Lidocaine enhances the effect of other antiarrhythmic drugs, beta-blockers and calcium channel blockers, which can lead to an excessive drop in pressure and slowing of the rhythm. Cimetidine, amiodarone and some antifungal drugs slow down its metabolism in the liver, increasing its concentration in the blood. Concomitant use with other local anesthetics cumulatively increases the risk of toxicity. Sedatives, sleeping pills and opioid analgesics can increase the depression of the central nervous system.
Combination with alcohol is undesirable: ethanol increases the inhibitory effect on the nervous system and increases the likelihood of dizziness, nausea and drop in pressure. After using large doses, a temporary decrease in concentration and reaction speed is possible, so driving vehicles and working with mechanisms for several hours is not recommended. When using small topical doses, these restrictions are usually not necessary, but you should be guided by your own well-being.
Where to buy HOW TO TAKE LIDOCAINE in Ukraine
Preparations with lidocaine are available in pharmacy chains throughout Ukraine, as well as through licensed online pharmacies with the possibility of delivery by postal operators or courier. Injectable forms are prescription-only, while sprays, gels and creams for external use are usually over-the-counter, but this does not eliminate the need for prior consultation with a doctor. When ordering, you should check the availability of quality certificates, the integrity of the packaging and the expiration date.
Store the drug in a dry, dark place at a temperature up to 25 °C, aerosol cans — away from heat sources and open flames, avoiding freezing of solutions. Children's access to the product must be prevented, and an opened tube of gel is used within the period specified by the manufacturer. The individual reaction of the body always remains unpredictable, so the selection of the form, concentration and application scheme should be agreed with a doctor.
