How Long Is Bac Water Good For?
Bacteriostatic water, commonly referred to as Bac water, is a sterile water solution containing a small amount of benzyl alcohol. It is commonly used to reconstitute medications, particularly those that come in powder form. Bac water helps to maintain the stability and integrity of medications, making them safe for use. However, it is crucial to know how long Bac water remains effective and safe to use.
The shelf life of Bac water depends on several factors, including the brand, storage conditions, and the presence of any contaminants. Generally, unopened Bac water vials have a shelf life of about two to three years. It is important to refer to the manufacturer’s instructions for the specific brand of Bac water you have.
Once opened, Bac water should be stored in a refrigerator at a temperature between 2 to 8 degrees Celsius (36 to 46 degrees Fahrenheit). When stored correctly, it can remain usable for up to 28 days. It is essential to check the expiration date on the vial and discard any Bac water that has passed this date.
