Benzyl Alcoh 0 .9%

0.9% benzyl alcohol refers to a common concentration of benzyl alcohol used as a bacteriostatic preservative in sterile water, creating bacteriostatic water for injection, which prevents microbial growth in multi-dose vials used to dilute medications for injection (IV, IM, SC). It's also used in research settings (RUO) for reconstituting lab reagents. The key difference from plain sterile water is the preservative, allowing for repeated withdrawals, but it should not be used in newborns due to "gasping syndrome" risks
