This medicine contains lidocaine hydrochloride and belongs to a group of medicines called local anesthetics of the amide type. It is used to block pain by reducing the conduction of nerve impulses near its site of action.

Lidocaine B. Braun is used to provide anesthesia by local injection around nerves or areas where surgical procedures are to be performed.

2. What you need to know before you use Lidocaine B. Braun

Do not useLidocaine B. Braun

• If you are allergic to lidocaine, other local anesthetics of the amide type, or any of the other ingredients of this medicine (listed in section 6).

• For epidural anesthesia in patients with pronounced hypotension (very low blood pressure) or cardiogenic shock (the heart pumps blood inadequately) or hypovolemic shock (severe loss of blood or body fluids).

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to use Lidocaine B. Braun:

• if you are an elderly person or are in a weakened general condition
• if you have heart problems such as slow or irregular heartbeat or heart failure.
• if you have any lung or respiratory disorders.

-------------------------------------------------------------------------------------------

This information is intended only for healthcare professionals:

Dosage and administration

Lidocaine B. Braun should only be used by doctors with experience in regional anesthesia and resuscitation techniques or under their supervision. Resuscitation equipment should be available when local anesthetics are administered. The lowest possible dose that produces the desired effect should be given. The dose must be adjusted individually according to the particularities of each case.

Dosage

Adults

When injected into tissues with high systemic absorption, the single dose of lidocaine hydrochloride should not exceed 400 mg. The following table can serve as a guide for adults with a body weight of approximately 70 kilograms. The dose should be adjusted according to the age, weight, and condition of the patient:

To prolong anesthesia, lidocaine may be combined with a vasoconstrictor, such as adrenaline. The addition of adrenaline to a concentration of 1/100,000 to 1/200,000 has been shown to be effective.

Pediatric population

The doses are calculated individually according to the age and body weight of the patients and the nature of the procedure. The anesthesia technique should be carefully selected, and techniques that are painful should be avoided. The child's behavior should be closely monitored during treatment. The average dose to be administered is in the range of 20 mg to 30 mg of lidocaine hydrochloride per session. The dose in mg of lidocaine hydrochloride that can be administered to children can also be calculated using the expression: child's weight (in kilograms) x 1.33.

The equivalent of 5 mg of lidocaine hydrochloride per kilogram of body weight should not be exceeded.

To prevent systemic toxicity in children, the effective lowest concentration should always be used.

Lidocaine is indicated in adults and children. However, it should be used with special caution in children under four years of age, as there are limited data to support the safety and efficacy of this product in this patient population at this time.

Lidocaine injectable is not recommended for use in newborns (see section 5.2). In this age group, the optimal concentration of lidocaine in serum necessary to avoid toxic effects such as convulsions and cardiac arrhythmias is unknown.

Special populations

In patients with renal or hepatic insufficiency and in elderly patients, the dose should be reduced according to the age and physical condition of the patient (see sections 4.4 and 5.2).

Form of administration

The form of administration of lidocaine varies depending on the anesthesia procedure used (infiltration anesthesia, intravenous regional anesthesia, nerve block, or epidural anesthesia).

Lidocaine B. Braun can be administered intramuscularly, subcutaneously, intradermally, perineurally, epidurally, or intravenously (in local intravenous anesthesia or Bier block).

Interaction with other medicines and other forms of interaction

Drugs that inhibit the metabolism of lidocaine (e.g., cimetidine) may cause potentially toxic plasma concentrations when lidocaine is administered repeatedly in high doses over prolonged periods. Such interactions are of no clinical relevance during short-term treatment with lidocaine at the recommended doses.

Lidocaine should be used with caution in patients who receive other local anesthetics or antiarrhythmic drugs of class Ib, as toxic effects are cumulative.

No specific interaction studies have been conducted with lidocaine and antiarrhythmic drugs of class III (such as amiodarone), but caution is recommended (see section 4.4).

Special Warnings and Precautions for Use

In general, before injecting lidocaine, it should be ensured that all emergency resuscitation equipment and medications for the treatment of toxic reactions are available instantly. In the case of major blocks, an intravenous cannula should be inserted before injecting the local anesthetic. Like all local anesthetic agents, lidocaine can cause acute toxic effects on the cardiovascular system and central nervous system when high blood concentrations occur, especially after extensive intravascular administration.

Caution should be exercised in the treatment of the following categories of patients:

• Elderly and debilitated patients in general.
• Patients with AV block II or III, as the local anesthetic may reduce myocardial conductivity.
• Patients with congestive cardiac failure, bradycardia, or impaired respiratory function.
• Patients with severe hepatic disease or renal insufficiency.
• Patients with epilepsy. These patients should be carefully monitored to detect the appearance of central nervous system symptoms. An increase in the tendency to convulsions should be considered even with doses below the maximum.
• Patients with coagulopathy. Treatment with anticoagulants (e.g., heparin), NSAIDs, or plasma substitutes increases the tendency to bleeding. Accidental injury to blood vessels can cause severe bleeding. If necessary, the bleeding time and activated partial thromboplastin time (APTT), rapid test, and platelet count should be checked.
• Third trimester of pregnancy
• In children under 4 years of age, as safety and efficacy data are limited
• In newborns, special caution should be exercised (see section 5.2)

Patients treated with class III antiarrhythmic drugs (e.g., amiodarone) should be closely monitored, and ECG monitoring should be considered, as the cardiac effects of lidocaine and class III antiarrhythmic drugs can be cumulative (see section 4.5).

There have been post-marketing reports of cases of chondrolysis in patients who received continuous postoperative intra-articular infusion of local anesthetics. In most of the reported cases of chondrolysis, the shoulder joint was involved. Due to the multiple contributing factors and the inconsistency in the scientific literature regarding the mechanism of action, causality has not been established. Continuous intra-articular infusion is not an approved indication for lidocaine (see section 4.8).

Epidural anesthesia can cause serious adverse effects, such as cardiovascular depression, especially in cases of concomitant hypovolemia. Caution should always be exercised in patients with reduced cardiovascular function.

Epidural anesthesia can cause hypotension and bradycardia. This risk can be reduced by administering intravenous crystalloid or colloid solutions. Hypotension should be treated immediately with, for example, ephedrine 5-10 mg intravenously; repeat as necessary.

Paracervical block can occasionally cause fetal bradycardia or tachycardia, and it is necessary to closely monitor fetal heart rate (see section 4.6).

Traumatic nerve injuries and/or local toxic effects on muscles and nerves are mainly caused by the injection of local anesthetics. The extent of these tissue lesions depends on the magnitude of the trauma, the concentration of the local anesthetic, and the duration of exposure of the tissue to the local anesthetic. For this reason, the minimum effective dose should be used.

Special caution should also be exercised when injecting the local anesthetic into inflamed (infected) tissue due to the increased systemic absorption caused by increased blood flow and the decreased effect due to the lower pH of infected tissue.

Once the tourniquet is removed after intravenous regional anesthesia, there is a higher risk of adverse reactions. Therefore, the local anesthetic should be eliminated in several fractions.

During anesthetic procedures in the neck and head region, patients are exposed to a higher risk of toxic effects of the drug on the central nervous system, even at low doses (see section 4.8).

Rarely, retro-ocular injections can reach the cranial subarachnoid space, causing intense/severe reactions, including cardiovascular collapse, apnea, convulsions, and transient blindness.

Retro- and periocular injections of local anesthetics carry a low risk of persistent ocular motor dysfunction. The main causes include trauma and/or local toxic effects on muscles and/or nerves.

Intramuscular lidocaine can increase creatine phosphokinase concentrations, which can interfere with the diagnosis of acute myocardial infarction.

Lidocaine injectable is not recommended for use in newborns (see section 5.2).

It has been shown that lidocaine is porphyrogenic in animals and should not be administered to patients with acute porphyria unless it is absolutely unavoidable. Precautions should be taken in all patients with porphyria.
