Does bacteriostatic water expire
Bacteriostatic water, a solution used for diluting substances for injection, contains 0.9% benzyl alcohol as a preservative, inhibiting bacterial growth up to 28 days post-opening. While sealed, it lasts for years. However, once opened, its efficacy drops and it’s no longer safe after 28 days, regardless of appearance. Proper storage can prolong its utility, but adherence to expiration dates ensures safety, especially for athletes and medical use. Using expired water can risk contamination, underscoring the importance of timely usage and proper handling.
