Chlorhexidine gluconate antiseptic – A skin preparation that kills bacteria by disrupting its cell membrane and precipitating the cell contents. CHG has a persistent effect and has cumulative biocidal action. Keep out of ears and eyes. The addition of ethyl alcohol (50-70%) or isopropyl alcohol (70-95%) speeds the bacterial kill effect. It kills both gram-positive and gram-negative microbes, although it is less effective with some gram-negative microbes. It is scored as fair against yeasts and fungi, and is effective against enveloped viruses, but not non-enveloped viruses. It does not kill spores. It is both bactericidal and bacteriostatic depending on concentration, microorganism and environment. If there is a contraindication to chlorhexidine, tincture of iodine, an iodophor, or 70% alcohol can be used as alternatives
