From the Guidelines
Chlorhexidine (Hibiclens) is the preferred choice for skin preparation due to its association with a lower rate of surgical site infections compared to Povidone-Iodine (Betadine) 1. The uses of Chlorhexidine (Hibiclens) and Povidone-Iodine (Betadine) are primarily focused on preventing infection and promoting antimicrobial activity.
Key Differences and Uses
- Hibiclens is used for skin cleansing, wound care, and as a surgical scrub, providing residual antimicrobial activity for up to 24 hours after application.
- Betadine is commonly used for wound disinfection, pre-surgical skin preparation, and treating minor cuts, scrapes, and burns.
Mechanism of Action
- Hibiclens works by disrupting bacterial cell membranes.
- Betadine releases free iodine that penetrates cell walls and disrupts protein synthesis and cell membrane function.
Important Considerations
- When using either product, it's crucial to follow package instructions and avoid contact with eyes, inner ears, and mucous membranes.
- Hibiclens should not be used on open head or facial wounds due to potential neurotoxicity risks.
- Individuals with allergies to either chlorhexidine or iodine should avoid the respective products and consult healthcare providers before use. According to the most recent and highest quality study, chlorhexidine-alcoholic solution is associated with a lower rate of surgical site infections compared to povidone-iodine solution 1, making it the preferred choice for skin preparation in surgical settings.

From the Research
Uses of Chlorhexidine (Hibiclens) and Povidone-Iodine (Betadine)
- Chlorhexidine (Hibiclens) and Povidone-Iodine (Betadine) are used as antiseptic agents for preoperative skin preparation to prevent surgical site infections 4, 5, 6, 7, 8
- Chlorhexidine is used in various concentrations, including 0.2% and 4% (Hibiclens), while Povidone-Iodine is used in a 10% concentration (Betadine) 4, 6, 7, 8
- These antiseptics can be used alone or in combination with other agents, such as isopropyl alcohol, to enhance their antimicrobial efficacy 4, 5, 6, 8
Antimicrobial Efficacy
- Chlorhexidine has been shown to have higher antimicrobial efficacy than Povidone-Iodine in several studies 6, 7, 8
- A study found that 0.2% chlorhexidine had higher antimicrobial efficacy than 10% Betadine for perioral skin disinfection prior to oral surgical procedures 7
- Another study found that chlorhexidine-alcohol was more protective against surgical site infections than povidone-iodine in clean-contaminated surgery 6
Prevention of Surgical Site Infections
- Chlorhexidine has been shown to be superior to Povidone-Iodine in preventing postoperative surgical site infections, especially in clean-contaminated surgery 6, 8
- A systematic review and meta-analysis found that chlorhexidine was superior to povidone-iodine in preventing postoperative surgical site infections, with a risk ratio of 0.65 (95% CI, 0.55-0.77; p < 0.00001) 8
- However, there was no statistically significant difference in the incidence of skin adverse events between chlorhexidine and povidone-iodine groups 8
