Chlorhexidine

Introduction: What is Chlorhexidine?

Chlorhexidine is an antiseptic agent widely used in medical settings for its effective antimicrobial properties. It is primarily employed to prevent infections in various clinical situations, including surgical procedures, wound care, and oral hygiene. Chlorhexidine is available in several forms, including solutions, gels, and mouthwashes, making it versatile for different applications.

Uses of Chlorhexidine

Chlorhexidine has several approved medical uses, including:

How It Works

Chlorhexidine works by disrupting the cell membranes of bacteria, leading to their death. It binds to the bacterial cell wall, causing leakage of essential cellular components.
