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.

Warnings

You should not receive tetracaine injection if you are allergic to tetracaine injection or any other type of numbing medicine.

Before taking this medicine

• high blood pressure;

• heart disease, heart rhythm disorder;

• any type of infection;

• hereditary angioedema or allergic reactions; or

How is tetracaine given?

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.

What happens if I miss a dose?

Since tetracaine is given as needed before a surgery or other medical procedure, you are not likely to be on a dosing schedule.

What happens if I overdose?

Since tetracaine injection is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

What should I avoid after receiving tetracaine?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.
