How to Check If a Pharmacy Has Sterile Water for Injection In Stock (Without Calling)

If you need Sterile Water for Injection (SWFI) and it's been in short supply since 2021, you already know the frustration: calling pharmacy after pharmacy, being put on hold, and being told 'we don't carry that' or 'we're out of stock.' There's a better way.

This guide walks you through the most efficient tools and strategies for checking whether a pharmacy has Sterile Water for Injection in stock—without necessarily having to make dozens of calls yourself.

Method 1: Use medfinder

The most direct solution is medfinder—a service that does the calling for you. You provide your medication name, dosage, and ZIP code; medfinder contacts pharmacies near you to check which ones can fill your prescription and texts you the results. As a paid service, medfinder is designed for exactly this scenario: a medication in shortage where you need to check multiple locations quickly without hours of hold music.

Method 2: Check the FDA Drug Shortage Database

The FDA's Drug Shortage Database at accessdata.fda.gov/scripts/drugshortages is the authoritative source on shortage status. While it doesn't show individual pharmacy inventory, it tells you:

Which specific NDC codes for Sterile Water for Injection are currently available vs. limited.

Which manufacturers are currently shipping (so you know which brands to ask about).

When a shortage is estimated to be resolved, so you can plan refill timing.

Armed with this information—specifically which NDC codes are currently in better supply—you can ask pharmacies targeted questions rather than a generic 'do you have sterile water for injection?'

Method 3: Ask Your Infusion Pharmacy to Check Multiple Wholesalers

If you receive home infusion therapy, your infusion pharmacy is your front-line supply manager. Request that they check their allocation status across multiple wholesale distributors—McKesson, AmerisourceBergen, and Cardinal Health all distribute SWFI, and allocation levels can differ significantly between distributors. A pharmacy that is capped on one distributor may have availability through another.

Method 4: Call Compounding Pharmacies Directly

Compounding pharmacies use SWFI as an ingredient in sterile preparations and often have access to supply that retail pharmacies do not. If you've struck out at chain and independent pharmacies, call licensed compounding pharmacies in your area and ask whether they can supply SWFI or provide your medication pre-mixed in a form that doesn't require you to reconstitute it.

Method 5: Check Licensed Online Medical Supply Retailers

Several licensed online medical supply retailers (such as Mountainside Medical or Westend Medical Supply) sell SWFI and Bacteriostatic Water to licensed healthcare professionals and individuals with a valid prescription. Check their websites directly for current stock status. Note that shortage conditions and manufacturer allocation affect these retailers too—stock can change rapidly. Make sure any online purchase is from an FDA-registered and legitimately licensed source.

Method 6: Ask About Different Vial Sizes

The SWFI shortage does not affect all vial sizes equally. A pharmacy that is out of 10 mL vials may have 20 mL or 50 mL vials in stock. When calling pharmacies, specify the vial sizes you need and ask whether other sizes are available. Your pharmacist can confirm whether a larger vial can be used safely for your medication protocol.

Tips for When You Do Have to Call

If you do need to call pharmacies directly, these tips will make the calls more efficient:

Ask for the pharmacy specifically (not the store's main number) to reach someone who can actually check inventory.

Know the NDC code and vial size you need—this allows the pharmacist to check their system precisely.

Ask whether they can order it and when they expect to receive it, even if not currently in stock.

Call in the morning—pharmacy staff are more available to assist before peak hours.

The Fastest Path: medfinder

Of all these methods, medfinder is the fastest and least frustrating. Rather than spending hours managing calls yourself, medfinder handles the outreach on your behalf and texts you the results.
