FAQ
- What is the NDC number for Hospira bacteriostatic water?
- The 30 ml plastic multi-dose vial carries NDC 0409-3977-03 (carton) and 0409-3977-01 (vial); the 20 ml glass vial is NDC 0409-1093. Always cross-check against the FDA's NDC Directory to confirm authenticity.
- How can I tell if bacteriostatic water is fake or mislabeled?
- Confirm the NDC matches the FDA directory, the flip-top seal is fully intact, and the lot number and expiry date are clearly printed on the vial. Missing labeling, unlisted NDCs, or repackaged containers are key red flags.
- What preservative is in bacteriostatic water and why does it matter?
- USP bacteriostatic water contains benzyl alcohol — 0.9% (9 mg/mL) in the 30 ml Hospira vial — which inhibits bacterial growth and permits multiple draws from one vial without spoilage, unlike single-use sterile water.
- Which brands sell 30 ml bacteriostatic water, and how do their prices compare?
- Preppin Peppers carries 30 ml bacteriostatic water alongside the reconstitution pens and 3 ml glass cartridges it's meant to pair with. Rather than comparing brands on price, focus on what actually tells you a vial is legitimate: check that it prints an NDC number, look that NDC up in the public FDA NDC directory, and confirm the flip-top seal is intact with a clear lot number and expiry date. Be wary of vials with no NDC, a code that doesn't match the directory, or a benzyl-alcohol percentage different from what's printed on the label.
