What is Tetracaine Injection?
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.
Warnings
You should not receive this medicine if you are allergic to tetracaine injection or any other type of numbing medicine.
Tell your doctor if you have ever had:
- high blood pressure;
- heart disease, heart rhythm disorder;
- any type of infection;
- hereditary angioedema or allergic reactions; or
- a disease or medical condition that affects your brain or spinal cord.

How should I use Tetracaine Injection
Use Tetracaine Injection (Niphanoid) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
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.
Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely while you are receiving tetracaine injection.
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.
Since tetracaine is given as needed before a surgery or other medical procedure, you are not likely to be on a dosing schedule.
