What is Lidocaine Injection?
Lidocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body. Lidocaine injection is used to numb an area of your body to help reduce pain or discomfort caused by invasive medical procedures such as surgery, needle punctures, or insertion of a catheter or breathing tube.
Lidocaine injection is sometimes used to treat irregular heart rhythms that may signal a possible heart attack. Lidocaine injection is also given in an epidural (spinal block) to reduce the discomfort of contractions during labor.
