ChloraPrep is a rapid-acting, persistent, and broad-spectrum antiseptic for a range of minor and major medical procedures. The 2 percent chlorhexidine gluconate, 70 percent isopropyl alcohol formula acts on a broad spectrum of bacteria, including Methicillin-resistant Staphylococcus aureus (MRSA), and keeps fighting bacteria for at least 48 hours, the company says. Together, the formulation and applicator provide a system that supports infection control guidelines and demonstrates a low incidence of irritation. The product comes in a range of applicators designed for specific procedures.
