BACTERIOSTATIC WATER

Sterile-Water

Definition:

Bacteriostatic Water is a sterile solution used primarily to dissolve or dilute medications for injection. It

contains water that is treated to prevent bacterial growth, thanks to the addition of a bacteriostatic

agent, typically benzyl alcohol.

Components:

Sterile Water: Purified water that is free from any contaminants, used as a base for the solution.

Benzyl Alcohol (0.9%): A preservative added to prevent the growth of bacteria and extend the

usability of the solution once it has been opened. Uses:

Reconstitution of Medications:

Often used to dissolve or dilute injectable drugs that come in powder form. This makes it possible to

inject medications that require mixing before use.

Dilution: Used to adjust the concentration of injectable solutions to the desired dosage.

Benefits:

Prevents Contamination: The benzyl alcohol helps to inhibit bacterial growth, ensuring that the

solution remains sterile for a longer period once it has been opened.

Extended Shelf Life: The preservative allows for a longer period of use compared to non-bacteriostatic

solutions.

Administration:

Injection Preparation:

When preparing medications for injection, Bacteriostatic Water is added to the medication vial to

achieve the correct concentration. It is essential to use sterile techniques to avoid contamination.
