What is the effect of using topical anesthetics before injections?

• A. They can significantly reduce the discomfort associated with immunizations.
• B. They prolong the procedure.
• C. They have no effect on pain.
• D. They cause infection.

Answer: (A)

Topical anesthetics work by numbing the skin so the needle’s penetration causes less pain. When applied before injections, they significantly reduce the discomfort of immunizations, helping children tolerate shots better and making immunization visits less distressing. For best effect, follow the product’s timing instructions so the area has enough time to numb before the injection. Mild skin irritation can occur, and rare systemic risks exist with certain agents in very young children, so use appropriate products and dosing. Overall, the main outcome is a noticeable decrease in pain during the shot.
