The price of bacteriostatic water can vary based on several factors, including the brand, volume, and where it is purchased. For example, a 100ml vial of bacteriostatic water might cost between $10 and $20 USD. Smaller vials, such as 30ml, could be priced lower, potentially in the $5 to $10 range. Prices can also differ between online retailers and physical pharmacies.
How is bacteriostatic water used?
Bacteriostatic water is a sterile, non-pyrogenic water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is primarily used as a diluent for parenteral medications that require reconstitution before injection. The benzyl alcohol helps prevent bacterial growth in the vial after it has been opened and used multiple times. [1]
What is the difference between bacteriostatic water and sterile water?
The key difference lies in the presence of a preservative. Sterile water for injection is simply sterile water without any additives. It is suitable for single-dose applications where no bacterial contamination is expected after opening. Bacteriostatic water, however, contains benzyl alcohol, making it suitable for multiple-dose vials where sterility needs to be maintained between uses. [1]
Can bacteriostatic water be used for all injections?
Bacteriostatic water is not suitable for all injections, particularly for certain patient populations or specific medications. It should not be used for intravenous administration or in neonates due to the potential risks associated with benzyl alcohol. Additionally, some medications may be incompatible with benzyl alcohol, requiring the use of sterile water for injection or another diluent. [1]
Where can I buy bacteriostatic water?
Bacteriostatic water is typically available for purchase through pharmacies, medical supply stores, and online retailers. It is often sold in various sizes, such as 10ml, 30ml, and 100ml vials, to accommodate different usage needs.
Are there alternatives to bacteriostatic water for reconstitution?
Yes, sterile water for injection is a common alternative when a bacteriostatic agent is not required or is contraindicated. For some medications, other diluents like sterile saline or specific reconstitution solutions provided by the drug manufacturer may be recommended. Always consult the medication's instructions for use or a healthcare professional to determine the appropriate diluent. [1]
What are the risks associated with using bacteriostatic water?
The primary risk associated with bacteriostatic water is the presence of benzyl alcohol. This preservative can cause adverse reactions in certain individuals, including allergic responses. It is also contraindicated for use in neonates and for intravenous injections due to potential toxicity. [1]
What is the shelf life of bacteriostatic water?
The shelf life of bacteriostatic water is generally indicated by the expiration date on the vial. Once opened, the bacteriostatic properties help maintain sterility for a limited period, typically up to 28 days, provided it is stored correctly and aseptic techniques are used during withdrawal. However, it is crucial to follow the manufacturer's specific guidelines regarding the opened vial's usability.
