Used to produce temporary numbness of the eye surface during ophthalmic procedures such as tonometry, foreign body removal, corneal abrasions assessment, and minor eye surgeries. May also be used for other localized numbing applications as directed by a healthcare provider.
Tetcaine contains tetracaine, an ester-type local anesthetic that works by blocking sodium channels in nerve fibers, preventing the generation and conduction of nerve impulses in the applied area, thereby producing temporary loss of sensation.
For ophthalmic use only under medical supervision. Should not be used for prolonged periods as repeated use may delay healing or cause corneal damage. Patients should avoid touching or rubbing eyes while numb. Not for self-medication without healthcare provider direction. Allergic reactions are possible, particularly in patients with sulfa or ester anesthetic sensitivities.
