How to Check If a Pharmacy Has Rezdiffra (Resmetirom) in Stock (Without Calling)

If you're trying to find out whether a pharmacy near you stocks Rezdiffra (resmetirom), you've probably already discovered that the usual approaches don't work. You can't walk into Walgreens and ask. GoodRx won't show retail availability. And calling around can feel like a dead end when none of your local pharmacies have heard of it.

That's because Rezdiffra is a Limited Distribution Drug (LDD) — it's only stocked at specialty pharmacies, not at retail chains. Here's how to find it efficiently.

Why You Can't Check Stock the Normal Way

Standard pharmacy lookup tools — GoodRx, RxSaver, SingleCare — work by comparing prices at retail pharmacies. Rezdiffra is not dispensed at retail pharmacies, so it doesn't appear in their retail-focused inventory databases. Additionally, specialty pharmacies typically don't display inventory information publicly because their dispensing model is different (mail-order and patient-specific fulfillment, not walk-in pickup).

The supply question for Rezdiffra is less about "does this pharmacy have it on the shelf" and more about "which specialty pharmacy network covers my insurance and can process my prescription."

Method 1: Call Madrigal Patient Support (Fastest for Most Patients)

The fastest way to find out which specialty pharmacy can dispense Rezdiffra for you is to call Madrigal Patient Support at 877-219-7770. They have a real-time view of the specialty pharmacy network and can tell you:

Which specialty pharmacies carry Rezdiffra and are in your insurance's network

What documentation is needed to initiate prior authorization

How to enroll in savings programs to reduce your out-of-pocket cost

This is also the enrollment point for the Rezdiffra specialty pharmacy process — so calling Madrigal Patient Support is not just how you find the pharmacy, it's how you get the whole access process started.

Method 2: Call Your Insurance Plan's Specialty Pharmacy Line

Look at the back of your insurance card for a specialty pharmacy or pharmacy benefits phone number. Call and ask: "Which specialty pharmacy in your network carries Rezdiffra (resmetirom)? Do I need prior authorization to cover it?" Large commercial plans (Cigna, Aetna, UnitedHealthcare, Blue Cross Blue Shield) each have preferred specialty pharmacy partners.

Method 3: Use medfinder to Have Someone Else Do the Calling

If you don't want to navigate phone trees yourself, medfinder calls pharmacies on your behalf to find which ones can fill your prescription. You provide your medication, dosage, and location — medfinder does the calling and reports back to you via text. This is particularly useful when you're not sure whether the access issue is supply-related, insurance-related, or simply a matter of finding the right pharmacy partner.

Method 4: Check the Specialty Pharmacy Websites Directly

You can contact the major specialty pharmacies in the Rezdiffra network directly to ask about availability and what's needed to begin dispensing:

Accredo: accredo.com | 1-800-803-2523

CVS Specialty: cvsspecialty.com | 1-800-237-2767

Optum Specialty: optumspecialtypharmacy.com | 1-855-427-4682

AllianceRx Walgreens: alliancerxwp.com | 1-800-345-1985

However, note that which specialty pharmacy you can use depends on your insurance network. Calling the wrong one can result in an out-of-network fill at full price.

What About GoodRx and Drugs.com?

GoodRx (goodrx.com/rezdiffra) and Drugs.com may display pricing information and information about the Rezdiffra Copay Savings Card. They can be useful for understanding what to expect cost-wise. But their discount codes do not work at specialty pharmacies, and they cannot tell you whether a specific pharmacy has the drug in stock for you specifically.

The Real Question: Is It a Shortage or an Access Issue?

As of 2026, Rezdiffra is not in a drug shortage — Madrigal Pharmaceuticals has maintained supply. If you're having trouble getting the drug, it's almost certainly an access issue: prior authorization is pending, insurance hasn't been verified, the specialty pharmacy routing hasn't been completed, or the savings program hasn't been enrolled. Madrigal Patient Support (877-219-7770) is the best single call to make to resolve all of these at once.
