Side effects of Lidocaine in details

Systemic

Adverse experiences following the administration of Lidocaine are similar in nature to those observed with other amide local anesthetic agents. These adverse experiences are, in general, dose-related and may result from high plasma levels caused by excessive dosage, rapid absorption or inadvertent intravascular injection, or may result from a hypersensitivity, idiosyncrasy or diminished tolerance on the part of the patient. Serious adverse experiences are generally systemic in nature. The following types are those most commonly reported:

Central Nervous System

CNS manifestations are excitatory and/or depressant and may be characterized by lightheadedness, nervousness, apprehension, euphoria, confusion, dizziness, drowsiness, tinnitus, blurred or double vision, vomiting, sensations of heat, cold or numbness, twitching, tremors, convulsions, unconsciousness, respiratory depression and arrest. The excitatory manifestations may be very brief or may not occur at all, in which case the first manifestation of toxicity may be drowsiness merging into unconsciousness and respiratory arrest.

Drowsiness following the administration of Lidocaine is usually an early sign of a high blood level of the drug and may occur as a consequence of rapid absorption.

Cardiovascular System

Cardiovascular manifestations are usually depressant and are characterized by bradycardia, hypotension, and cardiovascular collapse, which may lead to cardiac arrest.

Allergic

Allergic reactions are characterized by cutaneous lesions, urticaria, edema or anaphylactoid reactions. Allergic reactions may occur as a result of sensitivity to local anesthetic agents. Allergic reactions as result of sensitivity to Lidocaine are extremely rare and, if they occur, should be managed by conventional means. The detection of sensitivity by skin testing is of doubtful value.

Neurologic

The incidences of adverse reactions associated with the use of local anesthetics may be related to the total dose of local anesthetic administered and are also dependent upon the particular drug used, the route of administration and the physical status of the patient. In a prospective review of 10,440 patients who received Lidocaine for spinal anesthesia, the incidences of adverse reactions were reported to be about 3 percent each for positional headaches, hypotension and backache; 2 percent for shivering; and less than 1 percent each for peripheral nerve symptoms, nausea, respiratory inadequacy and double vision. Many of these observations may be related to local anesthetic techniques, with or without a contribution from the local anesthetic.

In the practice of caudal or lumbar epidural block, occasional unintentional penetration of the subarachnoid space by the catheter may occur. Subsequent adverse effects may depend partially on the amount of drug administered subdurally. These may include spinal block of varying magnitude (including total spinal block), hypotension secondary to spinal block, loss of bladder and bowel control, and loss of perineal sensation and sexual function. Persistent motor, sensory and/or autonomic (sphincter control) deficit of some lower spinal segments with slow recovery (several months) or incomplete recovery have been reported in rare instances when caudal or lumbar epidural block has been attempted. Backache and headache have also been noted following use of these anesthetic procedures.

There have been reported cases of permanent injury to extraocular muscles requiring surgical repair following retrobulbar administration.

What is the most important information I should know about Lidocaine?

• Lidocaine gel is for external use only. Do not get it in your eyes, ears, nose, or mouth. If you get it in your eyes, rinse at once with cool tap water. Contact your doctor and protect your eyes until the numbness goes away.
• Lidocaine gel may cause numbness at the treated area. Do not scratch, rub, or expose the area to extreme hot or cold temperatures while numbness occurs.
• If your symptoms do not get better within 7 days, if they get worse, if they go away and come back, or if rectal bleeding occurs, check with your doctor.
• Do not use Lidocaine gel in large amounts, especially on damaged or blistered skin. Do NOT use more than the recommended dose, over large areas, or for longer than recommended without checking with your doctor. This may increase your risk of serous side effects.
• Tell your doctor or dentist that you use Lidocaine gel before you receive any medical or dental care, emergency care, or surgery.
• Lidocaine gel is flammable. Keep it away from sparks, heat, and fire. Be sure to cap the tube tightly when Lidocaine gel is not in use.

• Lidocaine gel may cause harm if it is swallowed. If you may have taken it by mouth, contact your poison control center or emergency room right away.
• Lidocaine gel should not be used in CHILDREN younger than 12 years old without first checking with the child's doctor; safety and effectiveness in these children have not been confirmed.
• PREGNANCY and BREAST-FEEDING: It is not known if Lidocaine gel can cause harm to the fetus. If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Lidocaine gel while you are pregnant. It is not known if Lidocaine gel is found in breast milk after topical use. If you are or will be breast-feeding while you use Lidocaine gel, check with your doctor. Discuss any possible risks to your baby.
