CDC Guidelines
- Safe Injection Practices: The Centers for Disease Control and Prevention (CDC) recommends using sterile, preservative-containing diluents (like bacteriostatic water) for multi-dose vials where multiple needle punctures are expected.
- Single Patient Use: Although bacteriostatic water contains a preservative, the CDC advises dedicated vials for a single patient whenever possible to prevent cross-contamination.
- Expiration & Storage: Discard vials 28 days after opening, or sooner if contamination is suspected.
Mechanism of Action
Bacteriostatic Water for Injection acts solely as a vehicle/diluent. The included benzyl alcohol serves as a bacteriostatic agent—preventing the growth of bacteria with each needle puncture, allowing for safe multiple-dose extraction within clinical use timelines. The water itself provides no pharmacological action.
Directions
- Inspect vial for particulate matter or discoloration before use; only clear, colorless liquid should be used.
- Disinfect rubber stopper with an appropriate antiseptic.
- Withdraw sterile water using a new, sterile syringe/needle each time.
- Safely reconstitute or dilute medication according to the specific drug’s instructions.
- Label and store vials properly. Discard unused contents after 28 days of first entry or if contamination is suspected.
Warnings
- Not for Neonatal Use: Bacteriostatic water contains benzyl alcohol, which has been associated with toxicity (e.g., "gasping syndrome") in newborns. Avoid use in infants under 1 month.
- Do Not Inject Alone: Not for direct intravenous or intramuscular injection without another medication.
- Allergic Reactions: Do not use in patients with hypersensitivity to benzyl alcohol.
- Single Patient Use Preferred: Do not share vials between patients despite the presence of preservative.
- Discard After 28 Days: Or sooner if sterility is compromised.
- Storage: Store at controlled room temperature (20° to 25°C/68° to 77°F).
Side Effects
When used as directed solely for mixing/reconstituting drugs, side effects are extremely rare. However, potential risks include:
- Local Reaction: Redness, swelling, or irritation at injection site (usually due to mixed medication)
- Benzyl Alcohol Toxicity: Especially in infants, excessive use can cause metabolic complications and serious reactions
- Allergic Reaction: Rare; includes rash, itching, or anaphylaxis
Seek immediate medical attention if an allergic reaction is suspected.
