How to Check If a Pharmacy Has Dificid in Stock

You have a prescription for Dificid (Fidaxomicin), and now you need to find a pharmacy that actually has it. The problem? Dificid is a specialty antibiotic that costs over $5,000 per course — and many pharmacies don't keep it on their shelves. Calling pharmacy after pharmacy is exhausting, especially when you're dealing with an active C. diff infection.

The good news: there are ways to check Dificid stock without picking up the phone. Here's how.

Why Dificid Can Be Hard to Find

Dificid isn't a medication that every pharmacy stocks routinely. There are a few reasons for this:

• High cost — Brand-name Dificid costs around $5,100 for a 10-day course. Many pharmacies are reluctant to stock expensive medications that may sit on shelves.
• Specialized use — Dificid is only used for C. diff-associated diarrhea, which limits demand compared to common antibiotics.
• Insurance requirements — Many insurance plans require prior authorization before covering Dificid, which can create delays and uncertainty about whether a prescription will actually be filled.
• Supply fluctuations — Periodic supply disruptions can make Dificid temporarily harder to find. For the latest on availability, see our Dificid shortage update.

If you're struggling to find Dificid, you're not alone. Here are the most efficient ways to locate it.

How to Check Stock Without Calling

1. Use Medfinder

Medfinder is designed specifically to help patients find medications that are hard to locate. Simply search for Dificid, enter your zip code, and Medfinder shows you which pharmacies near you have it in stock — no phone calls required.

This is the fastest way to find Dificid availability in your area, especially for specialty medications that chain pharmacies may not carry.

2. Check Pharmacy Apps and Websites

Major pharmacy chains have apps and websites that let you check drug availability or transfer prescriptions:

• CVS — Use the CVS app or website to check prescription status. You can also transfer your prescription to a different CVS location if your usual store doesn't have Dificid.
• Walgreens — The Walgreens app lets you manage prescriptions and check if they're ready. If Dificid isn't available at your location, ask about transferring to a store that has it.
• Walmart — Walmart's pharmacy app allows you to track prescriptions. Walmart's high-volume pharmacies may be more likely to stock or quickly order Dificid.
• Rite Aid — Similar functionality through their app and website.

While these apps don't always show real-time stock levels for specific drugs, they can tell you if your prescription has been received and is ready for pickup — which effectively confirms the medication is in stock at that location.

3. Use GoodRx to Compare Prices and Check Availability

GoodRx shows prices for Dificid (and generic Fidaxomicin) at pharmacies near you. While it's primarily a price comparison tool, if a pharmacy shows a price for Dificid on GoodRx, it typically means they can fill it. GoodRx also shows coupon prices — generic Fidaxomicin can be found for around $1,293 with a GoodRx coupon, compared to over $5,000 for brand-name.

4. Try Specialty and Mail-Order Pharmacies

If local retail pharmacies don't have Dificid, consider:

• Specialty pharmacies — These pharmacies focus on high-cost and hard-to-find medications. Your doctor or insurance company can recommend one. Many specialty pharmacies ship directly to your home.
• Mail-order pharmacies — Services like Amazon Pharmacy, Express Scripts, and OptumRx may stock Dificid or generic Fidaxomicin and deliver it to your door.

Keep in mind that C. diff infections need prompt treatment, so if you use a mail-order pharmacy, make sure delivery times work with your treatment timeline.

5. Ask About Generic Fidaxomicin

Since July 2025, Teva Pharmaceuticals has offered a generic version of Dificid (Fidaxomicin tablets). The generic is AB-rated, meaning it's therapeutically equivalent to the brand. Pharmacies may be more likely to stock the generic because it's significantly cheaper. If the brand isn't available, ask your pharmacist about substituting the generic — in most states, pharmacists can make this switch automatically.

If You Prefer to Call

Sometimes a quick phone call is the most direct approach. Here are tips to make it efficient:

• Call the pharmacy's dedicated prescription line — Skip the main store number and call the pharmacy directly.
• Have your prescription details ready — Tell the pharmacist you need Fidaxomicin 200 mg tablets, quantity 20 (10-day supply).
• Ask if they can order it — Even if a pharmacy doesn't have Dificid on hand, many can order it from their wholesaler for next-day delivery.
• Try hospital-affiliated pharmacies — Pharmacies connected to hospitals are more likely to stock specialty antibiotics like Dificid.

Once You Find It

After you've located a pharmacy with Dificid in stock:

• Confirm insurance coverage — Make sure your prior authorization (if required) has been approved before you go to pick it up.
• Ask about savings — Manufacturer coupons and discount cards can significantly reduce your cost. See our guide to saving money on Dificid.
• Pick it up promptly — Pharmacies may return specialty medications to stock if prescriptions aren't picked up within a few days.
• Start treatment right away — Take Dificid 200 mg twice daily for 10 days. Don't skip doses. For information about what to expect during treatment, read our guide on Dificid side effects.

Final Thoughts

Finding Dificid in stock can be frustrating, but you don't have to spend hours on the phone. Start with Medfinder to quickly see which pharmacies near you carry it. Ask about generic Fidaxomicin, which is more affordable and increasingly available. And remember — if your local pharmacy doesn't have it, specialty and mail-order pharmacies are solid backup options.

C. diff is a serious infection that needs prompt treatment. Don't let pharmacy availability delays keep you from getting the medication you need.
