What is tetracaine?
Tetracaine is a local anesthetic (numbing medicine). It works by blocking nerve signals in your body.
Tetracaine injection is given as an epidural injection into the spinal column to produce numbness during labor, surgery, or certain medical procedures.
Tetracaine may also be used for purposes not listed in this medication guide.
You should not receive tetracaine injection if you are allergic to tetracaine injection or any other type of numbing medicine.

Tetracaine is given as an injection through a needle placed into an area of your middle or lower back near your spine. You will receive this injection in a hospital setting.

Spinal numbing medicines can have long-lasting effects on certain body processes such as sexual function, bowel or bladder control, and movement or feeling in your legs or feet. Talk with your doctor about these effects.
