Tetracaine, also known as amethocaine, is an ester local anesthetic used to numb the eyes, nose, or throat.^[2] It may also be applied to the skin before starting intravenous therapy to decrease pain from the procedure.^[3] Typically it is applied as a liquid to the area.^[2] Onset of effects when used in the eyes is within 30 seconds and last for less than 15 minutes.^[2]

Common side effects include a brief period of burning at the site of use.^[2] Allergic reactions may uncommonly occur.^[4] Long-term use is generally not recommended as it may slow healing of the eye.^[2] It is unclear if use during pregnancy is safe for the baby.^[2] Tetracaine is in the ester-type local anesthetic family of medications.^[4] It works by blocking the sending of nerve impulses.^[2]

Tetracaine was patented in 1930 and came into medical use in 1941.^[5] It is on the World Health Organization's List of Essential Medicines^[6]
