Please see the guidance from MHRA, UK. Injuries have been reported even with the lower concentration (0.5% & 2.0%) solutions containing alcohol. we also had some injuries but milder ones -erythema in small babies when using chlohex. we were cleaning with saline after chlorhex to prevent injuries. this practice may compromise the antiseptic action of chlorhex. but is there any alternative?
