Chlorhexidine Impurities

Chlorhexidine is primarily used for:

• Pre-surgical skin disinfection
• Sterilization of surgical instruments
• Mouthwash for preventing gingivitis and plaque buildup
• Wound antiseptic in hospitals and first-aid kits
• Hand sanitization in healthcare settings

Chlorhexidine is still widely used, but its use has been reconsidered in some cases due to:

• Risk of allergic reactions – Severe hypersensitivity reactions, including anaphylaxis, have been reported.
• Increased bacterial resistance – Overuse may contribute to antiseptic resistance in some bacteria.
• Potential toxicity – Can cause irritation, skin burns, or chemical injuries, especially with prolonged exposure.

No, but Chlorhexidine is an active ingredient in some mouthwashes used to treat gingivitis and oral infections. While it is a powerful antiseptic, regular mouthwashes (e.g., Listerine, fluoride rinses) primarily freshen breath and do not provide the same antibacterial benefits as prescription-strength Chlorhexidine mouthwashes.

Yes, Chlorhexidine is generally safe for human skin when used as directed. However:

• It should not be used on deep wounds or large open areas due to potential toxicity.
• Prolonged or frequent use may cause skin irritation, redness, or allergic reactions.
• It should be kept away from the eyes and ears, as it can cause severe irritation.
