Xylocaine 2% Injection 30 Ml

Xylocaine 2% Injection 30 mL by Zydus Healthcare Limited

Name

Brand Name: Xylocaine 2% Injection Common Name: Lidocaine Hydrochloride (also known as Lignocaine Hydrochloride)

Composition

Each milliliter of Xylocaine 2% Injection contains 20 mg of Lidocaine Hydrochloride. In some formulations, multiple-dose vials may also contain methylparaben as a preservative.

Uses

Xylocaine 2% Injection is primarily used as a local anesthetic to produce numbness or loss of feeling in specific areas of the body. It is indicated for:

• Local or regional anesthesia through various techniques such as infiltration, peripheral nerve blocks (e.g., brachial plexus, intercostal), central neural techniques (e.g., lumbar and caudal epidural blocks), and spinal anesthesia.
• Dental anesthesia.
• Management of acute ventricular arrhythmias to stabilize the heart's rhythm, especially after acute myocardial infarction or surgery.

Dosage and Administration

Xylocaine 2% Injection should only be administered by a trained anesthesiologist or healthcare professional.

• Dosage is highly individualized, depending on the procedure, site of administration, vascularity of the tissues, depth of anesthesia required, and the patient's physical status, age, and weight.
• For local anesthesia without epinephrine, the maximum recommended dose for adults generally should not exceed 4.5 mg/kg of body weight, with a total maximum dose typically not exceeding 300 mg.
• For continuous epidural or caudal anesthesia, the maximum recommended dosage should not be repeated at intervals of less than 90 minutes.
• A test dose (e.g., 2 to 3 mL of 1.5% Lidocaine HCl) is recommended at least 5 minutes prior to injecting the total volume for lumbar or caudal epidural blocks to guard against unintentional subarachnoid or intravascular injection.
• The injection should always be made slowly with frequent aspirations to avoid inadvertent intravascular injection.

Side Effects

Common Side Effects:

• Drowsiness, lightheadedness, dizziness, anxiety, nervousness
• Nausea, vomiting
• Headache, backache, shivering

Serious Side Effects (Report to care team immediately):

• Central Nervous System (CNS) Toxicity: Restlessness, confusion, tinnitus, blurred or double vision, tremors, twitching, convulsions, respiratory depression, or respiratory arrest. Drowsiness can be an early sign of high blood levels.
• Cardiovascular Effects: Bradycardia (slow heart rate), hypotension (low blood pressure), cardiovascular collapse, or cardiac arrest.
• Allergic Reactions: Skin rash, itching, hives, swelling of the face, lips, tongue, or throat.
• Methemoglobinemia: Characterized by cyanotic skin discoloration (pale, gray, or blue skin, lips, or nails), headache, confusion, lightheadedness, fast heartbeat, or unusual tiredness. The risk may be increased in children younger than 6 months of age, elderly patients, or patients with certain inborn defects.

Precautions

• Hypersensitivity: Contraindicated in patients with a known history of hypersensitivity to amide-type local anesthetics.
• Hepatic Disease: Use with caution in patients with hepatic disease as lidocaine is metabolized by the liver, increasing the risk of toxic plasma concentrations.
• Cardiovascular Impairment: Use with caution in patients with impaired cardiovascular function or severe heart block, as they may be less able to compensate for changes associated with the drug.
• Elderly, Debilitated, and Children: Reduced doses are recommended for these patient populations commensurate with their age and physical condition.
• Intravascular Injection: Careful and constant monitoring of vital signs and consciousness is required after injection to detect early signs of systemic toxicity. Aspiration should be performed before injection to avoid intravascular administration.
• Head and Neck Blocks: Small doses in this area may lead to adverse reactions similar to systemic toxicity due to rapid absorption or unintended intravascular injection.
• Inflamed/Infected Areas: The effect of local anesthetics may be reduced if injected into an inflamed or infected area. Avoid use in the incision of abscesses.
• Other Medications: Use with caution in patients receiving other local anesthetics or antiarrhythmic drugs, as systemic toxic effects can be additive.

Storage

Store at controlled room temperature, between 20 to 25°C (68 to 77°F), or below 25°C. Protect from light. Single-dose products are preservative-free and any unused portion should be discarded after initial use.

What is Xylocaine 2% Injection used for?

Xylocaine 2% Injection (lidocaine hydrochloride) is a local anesthetic used to numb specific areas of the body to reduce pain and discomfort during various medical and surgical procedures. These procedures can include dental work, minor surgeries, diagnostic procedures, and other therapeutic interventions. It can also be used for regional anesthesia, such as nerve blocks or epidural anesthesia. Additionally, it is indicated for the management of ventricular arrhythmias (irregular heartbeat) associated with acute myocardial infarction or cardiac surgery.

How does Xylocaine 2% Injection work?

Xylocaine 2% Injection contains Lidocaine, which is a local anesthetic of the amide type. It works by blocking the transmission of pain signals from the nerves to the brain. Specifically, it stabilizes the neuronal membrane by inhibiting the flow of sodium ions into nerve cells. This action prevents the initiation and conduction of electrical impulses, leading to a temporary loss of sensation in the targeted area. When used for arrhythmias, it works by blocking cardiac sodium channels, which helps to normalize the heart rate.

What is the usual dosage for Xylocaine 2% Injection?

Xylocaine 2% Injection is administered by healthcare professionals, such as doctors or trained anesthesiologists. The dosage varies greatly depending on the patient's age, weight, physical condition, the area to be anesthetized, the type of procedure, and the technique of anesthesia used. For normal healthy adults, the maximum recommended dose of lidocaine HCl without epinephrine generally should not exceed 4.5 mg/kg (2 mg/lb) of body weight, with a total dose typically not exceeding 300 mg. When used with epinephrine, the maximum recommended dose usually does not exceed 7 mg/kg (3.5 mg/lb) of body weight, and generally not more than 500 mg. The lowest effective dose should always be used.

What are the possible side effects of Xylocaine 2% Injection?

Xylocaine 2% Injection is generally considered safe, but like all medications, it can cause side effects. Common side effects may include:

• Injection site reactions such as pain, swelling, or redness
• Dizziness or lightheadedness
• Nausea and vomiting
• Slow heart rate (bradycardia) or changes in blood pressure (low or high)
• Tingling or prickling sensation (paresthesia), especially around the mouth
• Blurred vision or ringing in the ears (tinnitus)
• Difficulty in passing urine, lower back pain, or difficulty walking

More serious, but rare, side effects can include severe allergic reactions, blood problems, or convulsions. Restlessness, anxiety, tremors, or drowsiness can be early warning signs of central nervous system toxicity.

Is Xylocaine 2% Injection safe during pregnancy or breastfeeding?

Pregnancy: Lidocaine is generally considered safe to use during pregnancy when administered judiciously and under medical supervision. It is regularly administered to pregnant women, including as an epidural during labor, and typically does not increase the risk of birth defects. However, it does pass quickly through the placenta, so doctors suggest using it only for established medical needs at normal doses to avoid potential negative effects on the infant if excessive amounts are used.

Breastfeeding: Lidocaine is likely safe to use during breastfeeding as it passes into breast milk in tiny amounts and is not well absorbed by the infant when swallowed. While allergic reactions in infants have been reported, they are rare. It's always advisable to consult your doctor or lactation consultant regarding any medication while breastfeeding.

Can Xylocaine 2% Injection be taken with other medications?

Yes, but caution is advised as Xylocaine 2% Injection can interact with other medications. It's crucial to inform your doctor about all medications you are taking, including over-the-counter drugs, supplements, and herbal remedies.

• Antiarrhythmic drugs: Concurrent use with other antiarrhythmic agents (e.g., procainamide, amiodarone) can enhance cardiodepressive effects and increase the risk of serious arrhythmias.
• Beta-adrenergic blockers (beta-blockers): Medications like propranolol or metoprolol can slow down lidocaine's metabolism, leading to increased plasma concentration and a higher risk of toxic effects, especially on the central nervous system.
• Monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants: If Xylocaine contains epinephrine, its administration with these drugs may produce severe, prolonged hypertension.
• Vasopressor drugs and ergot-type oxytocic drugs: Concurrent use can cause severe, persistent hypertension.
• Other local anesthetics: Using multiple local anesthetics can lead to an additive effect and increased toxicity.

What precautions should be taken?

• Administration: Xylocaine 2% Injection should only be administered by trained healthcare professionals. Injections should be made slowly with careful aspiration to avoid accidental intravascular injection, which can lead to toxic effects.
• Medical Conditions: Inform your doctor if you have liver, kidney, or heart problems (including heart block or slow heart rate), breathing disorders, blood problems (like hypovolemia), epilepsy, glaucoma, stroke, dehydration, low blood potassium levels, or muscle weakness. Patients with severe hepatic disease or impaired cardiovascular function are at greater risk of developing toxic concentrations.
• Allergies: Do not receive Xylocaine 2% Injection if you are allergic to lidocaine or other amide-type local anesthetics.
• Driving and operating machinery: Avoid driving or operating heavy machinery after receiving the injection as it may cause dizziness, drowsiness, and temporary loss of sensation, affecting coordination and reflexes.
• Injection sites: If the solution contains adrenaline, it should not be injected into a vein or used in areas like fingers, toes, ears, nose, or penis, as it could compromise blood supply.
• Monitoring: Careful and constant monitoring of cardiovascular and respiratory vital signs and the patient's consciousness is crucial after each injection.

What happens if a dose is missed?

Xylocaine 2% Injection is administered by a healthcare professional in a clinical setting, so missed doses are unlikely. The doctor or anesthesiologist will determine the correct dose and timing based on the procedure. If you have concerns about the timing or effectiveness of your anesthesia, discuss them with your healthcare provider.

How should it be stored?

Xylocaine 2% Injection should be stored at controlled room temperature, typically between 20°C to 25°C (68°F to 77°F). It should be protected from freezing and light. Always inspect the solution for clarity and particulate matter before use. Some formulations in multiple-dose vials may contain preservatives like methylparaben. Preservative-free formulations are often used for specific procedures like epidural or spinal anesthesia. Any unused portion of single-dose vials should be discarded.
