What is the difference between Bacteriostatic water vs sterile water for injection?
Bacteriostatic Sterile water for injection has an extra preservative agent added into the water called benzyl alcohol (BnOH). Benzyl alcohol is a colorless liquid that has low toxicity, and low vapor pressure. Sterile Water for injection is a single-dose sterile water that does not contain any bacteriostatic, antimicrobial agents, and added buffers.
How long does Bacteriostatic water last after it has been opened?
Hospira recommends that once a vial of Bacteriostatic Sterile water is open the preservatives will prolong its life for up to 28 days. After 28 days the vial needs to be discarded. Other USP Sterile waters without the bacteriostatic agent (single-dose vials) should be discarded after a single use.
