Benzocaine — Uses, Dosage, Side Effects & Safety

Drug class: Local Anesthetic

Overview

Benzocaine is a local anesthetic commonly used to relieve pain and discomfort caused by minor mouth, throat, or gum irritations, sore throat, teething, sunburn, insect bites, and minor skin irritations. It works by temporarily numbing the area where it is applied, blocking nerve signals in your body. Benzocaine is available in various forms, including gels, creams, sprays, and lozenges. It is typically used for short-term relief and should not be used for prolonged periods without medical supervision. Patients should be aware that overuse or misuse, especially in children, can lead to serious side effects. Always follow the instructions on the packaging or those provided by your healthcare provider. Do not use benzocaine products in children under 2 years old unless directed by a doctor, due to the risk of serious complications.
