Very rare (less than 1 in 10,000 people):

• allergic reactions (skin changes, hives, swelling);
• loss of sensation, inability to move (paralysis).

Frequency not known (cannot be estimated from the available data):

• anaphylactoid reactions (symptoms similar to allergic reactions, but with a different mechanism of action);
• metallic taste in the mouth;
• feeling of dizziness;
• excitement;
• restlessness;
• euphoria;
• muscle tremors;
• drowsiness;
• disorders of consciousness;
• headaches and dizziness;
• tinnitus;
• feeling of heat, cold, or numbness;
• loss of consciousness;
• seizures;
• decreased blood pressure;
• slowing of heart rate, which in severe cases can lead to cardiac arrest;
• increased difficulty breathing, which in severe cases can lead to respiratory arrest;
• vision disorders;
• nausea, vomiting.

After intravenous administration of lidocaine in multimodal analgesia (multimodal), the most common side effects were: drowsiness, feeling of fatigue, nausea, numbness of the lips, metallic taste in the mouth, and dizziness.

Dosing

The medicine can be used intravenously, infiltration, epidurally, and spinal.

Regional anesthesia

The maximum single dose of lidocaine for an adult patient is 200 mg (4.5 mg/kg body weight). The doses given are for guidance and apply to adults in good general health, without accompanying diseases.
In children, the dose should not exceed 3 mg/kg body weight. Lidocaine should be dosed individually, based on body weight and the patient's overall condition. During anesthesia, the patient should be monitored and their vital functions monitored.
The strength and duration of lidocaine's action depend on the concentration and volume of the solution used. Increasing the volume and concentration accelerates, prolongs, and intensifies the local anesthetic effect.
Lidocaine, like other local anesthetics, should be administered slowly, after performing an aspiration test, which allows for the avoidance of unintended intravascular administration.
During the performance of epidural anesthesia, the administration of the main dose of the anesthetic should be preceded by a test dose (3 to 5 ml of lidocaine hydrochloride with the addition of adrenaline). After accidental intravascular administration of the test dose, the adrenaline contained in it causes a pronounced acceleration of heart rate. Therefore, for 5 minutes after administration, the EKG recording should be monitored on the monitor screen. A negative test result authorizes the injection (at a rate of 25 to 50 mg/min) of the remaining dose of the anesthetic. The test dose also allows for the avoidance of risks associated with unintended epidural administration of the medicine, followed by total spinal anesthesia.
The intervals between subsequent doses of the medicine administered epidurally should not be less than 90 minutes.
The maximum dose of lidocaine administered during cervical block (during childbirth and in gynecology) should not exceed 200 mg every 90 minutes.
The smallest effective dose of lidocaine should always be used to limit the risk of overdose. The medicine can be diluted with a 0.9% sodium chloride solution.

Arrhythmias

To treat arrhythmias in adults, lidocaine is administered intravenously in a single dose of 50 to 100 mg, or in divided doses of 25 to 50 mg per minute. If the initial dose is not effective, the next dose (50 to 100 mg) can be administered after 5 minutes. The dose should not exceed 200 to 300 mg per hour.
In patients with a tendency to recur arrhythmias or resistant to the action of oral antiarrhythmic drugs, a continuous intravenous infusion of lidocaine can be used at a rate of 1 to 4 mg/min (20 to 50 µg/kg body weight/min) under constant EKG monitoring. The infusion should be discontinued when the arrhythmia subsides or when symptoms of overdose appear. In elderly patients, the dose should be adjusted according to the patient's overall condition.
Arrhythmias in children are treated with lidocaine administered intravenously in a dose of 0.8 to 1 mg/kg body weight, which can be repeated if necessary up to a total dose of 3 to 5 mg/kg body weight. Lidocaine can also be administered in a continuous intravenous infusion at a rate of 10 to 50 µg/kg body weight/min.

Treatment of pain in the perioperative period

Lidocaine administered intravenously in the perioperative period is used in adults as an adjunct in multimodal (multimodal) therapy and in preventive (pre-emptive) analgesia.
Lidocaine is administered intravenously during surgical procedures with minor to significant and extensive tissue trauma.
Typical dosing:

• loading dose of 1.5 mg/kg body weight administered in a bolus, followed by a continuous infusion of 1.5 to 3 mg/kg body weight/hour during surgery; it is recommended to start administering lidocaine 30 minutes before the induction of anesthesia, but no later than during the induction of anesthesia;
• in the postoperative period: 1 to 3 mg/kg body weight/hour in a continuous infusion for 24 to 48 hours.

If the patient is using lidocaine as a local anesthetic (e.g., infiltration along the planned incision line) and in intravenous infusion, the total dose of lidocaine should be reduced.
If necessary, the intravenous infusion of lidocaine can be started 4 to 8 hours after the administration of the last dose (in a bolus) of the medicine used in regional anesthesia. In the case of failed epidural anesthesia, after stopping the continuous infusion into the epidural space and without administering a dose into the epidural space in a bolus, the continuous intravenous infusion of lidocaine can be started immediately, but without administering an intravenous bolus.
The dose of lidocaine should be reduced in conditions where the free fraction of the medicine in the serum may increase - acidosis, hypercapnia, hypoxia, hypoproteinemia, and liver and/or kidney function disorders. In patients with circulatory, liver, and/or kidney failure, the dose of lidocaine should be reduced and the cardiovascular system should be monitored.

Treatment of patients with neuropathic pain

Adults
Continuous intravenous infusion at a dose of 3-5 mg/kg body weight for at least 30 minutes, but no longer than 6 hours, once a day.
Note: the medicine is incompatible and should not be mixed in the same syringe with solutions containing sodium bicarbonate and other alkaline solutions.
