What is Dilocaine (lidocaine injection)?
Lidocaine injection 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.
Lidocaine injection may also be used for purposes not listed in this medication guide.

How is Dilocaine (lidocaine injection)given?
A healthcare provider will give you this injection.
Lidocaine injection is injected into a vein through an IV to treat heart rhythm problems.
When used as a numbing medicine, lidocaine injection is injected through the skin directly into the body area to be numbed.
Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely while you are receiving lidocaine injection in a hospital setting.
If you are being treated for irregular heart rhythm, your heart rate will be constantly monitored using an electrocardiograph or ECG (sometimes called an EKG). This will help your doctor determine how long to treat you with lidocaine injection.

Since lidocaine injection is used only when needed in a clinical setting, you are not likely to miss a dose.
