Chlorhexidine is an antiseptic used to reduce bacteria and prevent infections. It is commonly found in mouthwashes, skin cleansers, and surgical scrubs. Chlorhexidine works by disrupting the cell membranes of bacteria, making it effective against a wide range of germs. This compound is often used in healthcare settings for hand hygiene and preoperative skin preparation. It is also used in dental care to help manage gum disease. While generally safe, some individuals may experience skin irritation or allergic reactions, so it is important to use it as directed.
