It works by temporarily numbing the affected area, thus reducing the sensation of pain. Benzocaine is available in various forms, such as creams, gels, lozenges, sprays, and liquids, and can be applied topically or used orally. It is often combined with other ingredients, such as antiseptics or anti-inflammatory agents, to provide more comprehensive relief. However, it is important to use benzocaine as directed and not exceed the recommended dose, as excessive use can cause serious side effects, such as methemoglobinemia, a condition that reduces the ability of red blood cells to carry oxygen.
