Alcaine

What is this medication? Alcaine is a prescription ophthalmic solution used to provide rapid, short-term local anesthesia to the surface of the eye. It contains the active ingredient proparacaine hydrochloride, which belongs to a class of medications known as local anesthetics. Healthcare providers typically administer these eye drops before performing diagnostic tests or minor procedures, such as measuring intraocular pressure, removing sutures, or extracting small foreign bodies from the cornea.

The medication works by temporarily blocking nerve signals in the eye, ensuring that the patient does not feel pain or discomfort during clinical evaluations. It generally begins to work within twenty seconds of administration and provides a numbing effect that lasts for about fifteen minutes. Because the eye is unable to feel sensation while the drug is active, it is critical for patients to avoid rubbing or touching the treated area until the anesthesia wears off to prevent accidental injury or irritation.
