Bacteriostatic Water – Educational Product Overview
Bacteriostatic water is a sterile, non-pyrogenic water for injection that contains a small amount of benzyl alcohol to inhibit the growth of bacteria. It is commonly used in clinical, pharmaceutical, and laboratory settings where maintaining sterility over multiple withdrawals is essential.
What Is Bacteriostatic Water?
Bacteriostatic is designed to dilute or reconstitute certain medications before administration, as directed by a qualified healthcare professional. The presence of benzyl alcohol (typically 0.9%) helps prevent bacterial contamination once the vial has been opened, allowing for controlled, multi-dose use when appropriate.
Unlike sterile water for injection, which must be used immediately after opening, bacteriostatic w. offers added protection against microbial growth, making it a preferred option in many professional healthcare environments.
