Benzocaine powder is applied topically to relieve minor skin irritation, sore throats, and dental problems due to its numbing properties. It is commonly available as over-the-counter medication products in lozenges, gels, and creams. The benzocaine powder uses involves the blocking of the signals through nerves to bring temporary relief to pain and discomfort. It also serves the purpose in terms of relief from sunburns, insect bites, or any other minor irritations to the skin. While generally safe for topical application, benzocaine powder should be used with caution, especially on children, as it may trigger a rare but dangerous condition called methemoglobinemia, which decreases the oxygen-carrying ability of blood.
