20% Benzocaine: Uses, Side Effects, and Drug Interactions

# Overview of 20% Benzocaine Benzocaine is a medicine that helps numb pain in your mouth and throat. It comes in a 20% strength, which means it's pretty concentrated. People use this product to get relief from painful mouth sores, sore throats, minor cuts in the mouth, and other small injuries inside your mouth. It works by blocking pain signals in the area where you use it, so you feel less discomfort. The numbness usually starts working pretty quickly, which is why many people use it when they have dental pain or after getting dental work done. However, you need to be careful when using benzocaine because it can have serious side effects if you don't use it correctly. Never use too much of this product, and don't use it more often than the label says you should. Keep this medicine away from children because they could accidentally swallow too much or misuse it. Stop using the product and call a doctor if you have any unusual reactions, feel dizzy, have trouble breathing, or notice swelling in your mouth or throat. Also, don't use benzocaine if you're allergic to it or similar medicines, and check with a doctor before using it if you have certain health conditions.
