Lidocaine Injection: A Local Anesthetic for Pain Relief

Lidocaine injection, also known as lignocaine injection, is a medication that can block the sensation of pain in a specific area of your body. It belongs to a group of drugs called local anesthetics, which work by preventing the nerves from sending pain signals to the brain.

Lidocaine injection can be used for various purposes, such as:

  • Minor operations, such as skin biopsies, suturing, or removal of foreign bodies
  • Dental surgery, such as tooth extraction, root canal treatment, or filling
  • Insertion of a catheter or breathing tube
  • Epidural anesthesia during labor and delivery
  • Treatment of irregular heart rhythms that may signal a possible heart attack

Lidocaine injection is usually given by a doctor or a nurse, who will inject it into the skin, muscle, vein, or spine, depending on the procedure and the area to be numbed. The dose and duration of lidocaine injection depend on several factors, such as your age, weight, medical condition, and response to the drug.

Side Effects and Precautions of Lidocaine Injection

Lidocaine injection is generally safe and effective when used as directed by your doctor. However, like any medication, it can cause some side effects and complications in some people. Some of the common side effects of lidocaine injection include:

  • Drowsiness, dizziness, or lightheadedness
  • Nausea, vomiting, or diarrhea
  • Feeling hot or cold
  • Confusion, ringing in the ears, blurred vision, or double vision
  • Numbness or tingling in places where the medicine is accidentally applied

Some of the serious side effects of lidocaine injection include:

  • Allergic reaction, such as hives, difficulty breathing, or swelling of the face, lips, tongue, or throat

  • Slow heart rate, weak pulse, low blood pressure, or cardiac arrest
  • Sudden feeling of heat, cold, or numbness
