Tetracaine is a local anesthetic commonly used to numb specific areas of the body during medical procedures. It works by blocking nerve signals in the targeted area, providing temporary pain relief. Tetracaine is often used in eye surgeries, dental procedures, and minor skin operations. This medication is available in various forms, including ointments, solutions, and eye drops. While generally safe when used as directed, it can cause side effects such as irritation or allergic reactions in some individuals. Proper dosage and administration are essential to minimize risks and ensure effective pain management.
