You Shouldn't Have to Call 10 Pharmacies to Find Your Medication

If you've been prescribed Hydroxocobalamin and your pharmacy told you it's out of stock, you're not alone. The ongoing Hydroxocobalamin shortage has left many patients scrambling to find a pharmacy that actually has it on the shelf.

The traditional approach — calling pharmacy after pharmacy — is time-consuming and frustrating. The good news is there are faster ways to check stock in 2026. Here's how to find Hydroxocobalamin without spending your afternoon on hold.

Why Is Hydroxocobalamin Hard to Find?

The generic Hydroxocobalamin IM injection (1,000 mcg/mL, 30 mL vial) has been in shortage since December 2025. The main manufacturer, Hikma/Actavis, has been unable to source enough active ingredient, with resupply estimated for June 2026. The Cyanokit IV formulation has also faced intermittent shortages.

For a deeper dive into the reasons behind the shortage, read our full explainer: Why Is Hydroxocobalamin So Hard to Find?

How to Check Stock Without Calling

1. Use Medfinder

Medfinder is built specifically for situations like this. Enter your medication name and zip code, and it shows you which pharmacies near you have Hydroxocobalamin available. It checks both chain pharmacies and independent pharmacies, and updates regularly so the information stays current.

This is especially useful during a shortage, when stock levels change daily. Instead of calling around, you can see results in seconds.

2. Check Pharmacy Apps and Websites

Several major pharmacy chains let you check medication availability through their apps or websites:

• CVS: Use the CVS app or website to search for your prescription. If the medication is out of stock at your usual location, it may show other nearby stores with availability.
• Walgreens: The Walgreens app lets you transfer prescriptions between locations. If your local store is out of stock, you can search for nearby stores that have it.
• Walmart: Walmart's pharmacy website and app allow you to check pricing and sometimes availability by location.
• Rite Aid: Similar functionality through their pharmacy app.

Keep in mind: these apps don't always show real-time stock levels for injectable medications. They're more reliable for common oral medications. For a shortage item like Hydroxocobalamin, Medfinder or calling ahead may be more accurate.

3. Use GoodRx to Compare Prices and Availability

While GoodRx is primarily a price comparison tool, it can also help you identify pharmacies that carry Hydroxocobalamin. Search for the medication on GoodRx, and it will show pricing at various pharmacies near you. If a pharmacy shows a price, it generally means they stock the medication — though during a shortage, this isn't guaranteed.

GoodRx coupons can also bring the price down to as low as $20.86 for a 30 mL vial. Read more about saving money on Hydroxocobalamin.

4. Check Compounding Pharmacies

During a shortage, compounding pharmacies are often your best bet. These pharmacies can prepare Hydroxocobalamin injections from raw ingredients, bypassing the commercial supply chain. Many compounding pharmacies list their available medications on their websites.

Search for "compounding pharmacy near me" or check directories like the Professional Compounding Centers of America (PCCA) website. Compounding pharmacies may offer Hydroxocobalamin in concentrations like 10 mg/mL or 20 mg/mL, which can be different from the standard commercial formulation.

5. Try Mail-Order and Online Pharmacies

Mail-order pharmacies sometimes have access to inventory that local pharmacies don't. Options include:

• Amazon Pharmacy
• Honeybee Health
• Cost Plus Drugs

These pharmacies may have longer lead times (a few days for shipping), so plan ahead if you're running low.

If You Prefer to Call

Sometimes calling is still the fastest option, especially for independent pharmacies that may not have robust online systems. Here are some tips to make it more efficient:

• Call early in the day — pharmacies are less busy in the morning, and staff have more time to check stock.
• Have your prescription details ready — know the exact medication name (Hydroxocobalamin), strength (1,000 mcg/mL), quantity (30 mL vial), and NDC number if you have it.
• Ask about estimated restock dates — if a pharmacy is out, they may know when their next shipment is expected.
• Ask about compounding — some pharmacies can compound Hydroxocobalamin even if the commercial product is unavailable.

Once You Find It

When you locate a pharmacy with Hydroxocobalamin in stock:

• Act quickly. During a shortage, stock can sell out within hours. Call to confirm availability and ask them to hold your prescription if possible.
• Transfer your prescription. If it's at a different pharmacy than usual, ask your doctor to send a new prescription, or request a transfer from your current pharmacy.
• Stock up if allowed. Ask your doctor if they can write for a larger quantity or multiple vials so you're not searching again next month. Some insurance plans will cover a 90-day supply.
• Consider self-injection. If you're not already self-injecting at home, ask your doctor about learning the technique. This gives you more flexibility with where you fill your prescription, since you don't need to go to a doctor's office for each dose.

If Hydroxocobalamin is completely unavailable in your area, talk to your doctor about alternatives like Cyanocobalamin or Methylcobalamin.

Final Thoughts

Finding Hydroxocobalamin during a shortage takes some extra effort, but you don't have to do it blindly. Tools like Medfinder take the guesswork out of pharmacy searches, and compounding pharmacies offer a reliable backup when commercial supplies run dry.

Start your search online, check compounding options, and don't hesitate to ask your doctor to help coordinate your supply. Your B12 treatment is important — don't let a shortage derail it.
