Benzocaine is a local anesthetic commonly used to relieve pain and discomfort in various medical and dental procedures. It works by blocking nerve signals in the area where it is applied, providing temporary numbness. Benzocaine is often found in over-the-counter products like throat lozenges, topical gels, and ointments for minor skin irritations. This compound is typically used for short-term relief and is considered safe when used as directed. However, it is important to follow dosage instructions carefully, as excessive use can lead to side effects, including allergic reactions or a rare condition called methemoglobinemia, which affects oxygen delivery in the blood.
