Bacteriostatic Water (Benzyl Alcohol/WFI)

What is Bacteriostatic Water?

Bacteriostatic Water is a sterile, purified water containing a small amount of benzyl alcohol, which acts as a preservative. It is commonly used in medical settings to dilute or dissolve medications that need to be injected either subcutaneously, intramuscularly, or intravenously. The presence of benzyl alcohol makes this water bacteriostatic, meaning it inhibits the growth and reproduction of bacteria, helping maintain the sterility of the solution between uses.

Manufactured by Syther Pharmaceuticals, this water ensures a safe, reliable medium for medication preparation. It’s a vital companion especially in clinical and research environments where injectable drugs require precise dilution without introducing contamination risks.

Uses of Bacteriostatic Water

• Diluting medications intended for subcutaneous injections
• Dissolving drugs before intramuscular injection
• Preparing intravenous medications by dilution
• Reconstituting powdered medications for injectable use
• Maintaining sterile environment for multi-dose vials

How Bacteriostatic Water Works

When medications come in powdered form or at concentrations too high for direct injection, they need to be diluted or dissolved before administration. Bacteriostatic Water provides a sterile, non-toxic liquid that serves as an ideal carrier. The benzyl alcohol within the water acts as a mild preservative, preventing bacterial growth which might otherwise occur between multiple uses of the vial. This means healthcare professionals can draw up medication doses over several injections safely, reducing waste.

It does not active medicines directly but supports their safe preparation by maintaining a contamination-free environment, making procedures safer for patients.

Benefits of Bacteriostatic Water

• Helps maintain sterility between multiple injections thanks to benzyl alcohol
• Reduces the risk of bacterial contamination during medication reconstitution
• Compatible with a wide range of injectable medications
• Facilitates accurate dosing by easily dissolving powdered drugs
• Produced under strict quality conditions by Syther Pharmaceuticals ensuring reliability

Dosage and Administration

The dosage of Bacteriostatic Water is typically determined by the amount of medication requiring dilution. Healthcare providers calculate the correct volume needed to dissolve or dilute the drug safely according to protocols or manufacturer instructions. The solution is intended only for injectable use and must be handled with aseptic technique.

It is important to use the bacteriostatic water only as instructed and avoid direct injection by itself unless specifically advised. Any unused portion in the vial should be stored properly for subsequent uses within the safe time frame indicated on the product packaging.

Who Should Use Bacteriostatic Water?

This product is intended for use by medical professionals and trained individuals who prepare injectable medication.
