chlorhexidineä

Chlorhexidine is a widely used antiseptic and disinfectant. Its chemical name is 1,6-di(4-chlorophenylbiguanido)hexane. It is effective against a broad spectrum of microorganisms, including Gram-positive and Gram-negative bacteria, yeasts, and some viruses. Its mechanism of action involves disrupting the cell membranes of microbes, leading to cell death.

Chlorhexidine is available in various concentrations and formulations, such as solutions, gels, and mouthwashes. It is commonly used in healthcare settings for skin disinfection before surgical procedures, for hand hygiene by healthcare professionals, and for wound care. In dentistry, it is prescribed as a mouthwash to treat gingivitis and other periodontal diseases. It is also found in some personal care products like soaps and cosmetics.

While generally safe and effective, chlorhexidine can cause side effects in some individuals. These may include skin irritation, allergic reactions, and a temporary staining of teeth and dental restorations, particularly with prolonged use of mouthwashes. It is important to use chlorhexidine as directed by a healthcare professional or product instructions. It is not recommended for internal use.
