Bacteriostatic Water Injection Multiple Dose Vials 30 mL Hospira 25/Pack (Rx)

Bacteriostatic Water for Injection 30 mL by Pfizer Injectables is a sterile, preservative‑containing diluent designed for safe, convenient reconstitution and dilution of parenteral medications. Supplied in 30 mL multiple‑dose vials and packaged 25 vials/pack, this high‑quality bacteriostatic water supports aseptic drug preparation in hospitals, clinics, infusion centers and outpatient settings. The bacteriostatic preservative permits multiple withdrawals for a single patient when used under proper aseptic technique, reducing waste while maintaining safety.

What it is used for

• Reconstitution of powdered injectable medications for parenteral administration (IM, SC, IV) as directed by the drug’s prescribing information.
• Dilution of liquid parenteral drugs to a required concentration prior to administration.
• Preparation of small‑volume injections when a preservative is acceptable by the drug manufacturer and clinical setting.

Details and features

• Sterile bacteriostatic water packaged in 30 mL multiple‑dose vials.
• Preservative‑containing formulation to permit multiple withdrawals for the same patient when aseptic technique is used (single‑patient use only).
• Pack size ideal for high‑volume clinical areas: 25 vials/pack.
• Manufactured to injectable standards for sterility and clarity.
• Clear labeling and vial design for easy handling and visual inspection prior to use.

Directions and administration

• Read and follow the reconstitution/dilution instructions in the specific drug’s prescribing information. Bacteriostatic water is a diluent only; it does not provide therapeutic effect.
• Use aseptic technique: disinfect vial septum with alcohol swab and allow to dry before each entry.
• Withdraw required volume using a sterile syringe and needle. Do not return used needles/syringes to the vial.
• Use a separate sterile syringe/needle for each withdrawal.
• Label the vial with date/time and patient name after first use (single‑patient multi‑dose use only) per facility policy.
• Discard any unused portion according to institutional policy and within the recommended time frame for multi‑dose vials (see Storage & Handling).

Dosage and reconstitution guidance

• Bacteriostatic water is a diluent; the volume to use is determined by the medication being reconstituted or diluted. Always follow the drug manufacturer’s reconstitution and administration instructions.
• Typical practice: add the volume specified on the drug label to achieve the required concentration (e.g., add X mL to Y mg vial). If no manufacturer instruction exists, consult pharmacy or product monograph.
• Do not use bacteriostatic water for large‑volume parenteral infusion or as a replacement for IV fluids unless explicitly directed by the medication labeling.

Allergies, contraindications and special populations

• Contraindicated in patients with known hypersensitivity to the preservative (benzyl alcohol) or any component of the product.
• Not for use in neonates, premature infants, or young infants unless preservative‑containing diluent is explicitly indicated — benzyl alcohol has been associated with fatal “gasping syndrome” in neonates.
• Use caution in patients with known sensitivity to benzyl alcohol or aromatic alcohols.

Drug interactions and compatibility

• Bacteriostatic water is a diluent; it does not interact pharmacologically, but the preservative can affect stability or suitability of some medications.
• Some products (e.g., certain ophthalmic, intrathecal/epidural, neonatal or preservative‑sensitive injectables) require preservative‑free diluents; do not use bacteriostatic water when preservative‑free solvent is specified.
• Always check compatibility and stability in the drug’s prescribing information, compendia, or with pharmacy staff before reconstitution or dilution.

Side effects, adverse reactions and warnings

• Local reactions: transient pain, erythema or irritation at the injection site may occur after administration of the reconstituted product.
• Hypersensitivity: allergic reactions to benzyl alcohol or other components may occur; signs include rash, urticaria, angioedema, bronchospasm, and anaphylaxis—be prepared to treat.
• Neonatal toxicity: benzyl alcohol–containing products have been associated with serious adverse events ("gasping syndrome") in neonates and premature infants; avoid use in this population unless explicitly recommended.
• Not for intrathecal or epidural use: preservatives can cause neurologic injury if administered into the central nervous system—use only preservative‑free diluent for these routes.
• Not for large‑volume IV infusion or irrigation: bacteriostatic water is sterile water and is hypotonic; inadvertent large‑volume IV administration may cause hemolysis or other complications.
• Risk of contamination: multi‑dose vials must be handled aseptically; improper handling can lead to infection or sepsis.

Storage and handling

• Store per manufacturer labeling (typically controlled room temperature unless otherwise specified). Protect from contamination. Do not freeze.
• After first entry, follow facility policies for multi‑dose vials. Many institutions limit use to 28 days after initial puncture when preservative is present—follow local policy and manufacturer guidance.
• Discard vial if solution becomes cloudy, discolored, or contains particulate matter.

Regulatory and clinical notes

• Prescription product intended for parenteral use; use only as a diluent for injectable medications when appropriate.
• Consult the reconstituted drug’s full prescribing information and institutional pharmacy for compatibility, stability and administration guidelines.
• For patient‑specific questions or unusual compatibility concerns, consult pharmacy, the manufacturer, or a clinical toxicologist.

Bacteriostatic Water Injection Safety Data Sheets 2025

Bacteriostatic Water for Injection 30 mL by Pfizer Injectables is a high‑quality, preservative‑containing diluent designed for safe, efficient reconstitution and dilution of many parenteral medications in clinical settings. Its 30 mL multiple‑dose vial format and 25‑pack presentation make it cost‑effective and convenient for hospitals, clinics, and outpatient centers that require repeated single‑patient withdrawals under aseptic technique.

When used appropriately, this product reduces waste and speeds medication preparation; however, strict adherence to drug manufacturers’ reconstitution instructions, aseptic handling, and institutional policies is essential. Do not use in neonates or for intrathecal/epidural administration unless a preservative‑containing diluent is explicitly indicated. Always verify compatibility with the medication being prepared and consult pharmacy for questions about stability or special populations.

For safe use and optimal outcomes, store and handle per manufacturer guidance, discard vials per facility protocols after the recommended in‑use period, and involve your pharmacy team for product selection and clinical support.
