ZIHEX is a nonsteroidal anti-inflammatory drug (NSAID) that works by preventing the release of certain chemical messengers that cause pain and inflammation (redness and swelling). Chlorhexidine Gluconate, an antiseptic that works by binding to the surface of the teeth, inner cheeks and gums, is still used to prevent common oral health problems such as bad breath, plaque, cavities, gum inflammation and tooth stains. ZEHEX mouthwash is also intended for gargling in the throat and is considered a suitable agent to eliminate bacteria in the oral cavity.
