How to Find Rezdiffra (Resmetirom) in Stock Near You (Tools + Tips)

Rezdiffra (resmetirom) is not like a typical prescription. You cannot pick it up at Walgreens or ask your local pharmacist to order it. Because it is a Limited Distribution Drug (LDD), Rezdiffra is only available through a select network of specialty pharmacies — and the process to get it is several steps longer than filling a standard prescription.

The good news: once you know how the system works, you can navigate it efficiently. This guide walks you through exactly how to find Rezdiffra in stock and get it dispensed as quickly as possible.

Step 1: Understand That Rezdiffra Is a Specialty Pharmacy Drug

Rezdiffra is classified as a Limited Distribution Drug by its manufacturer, Madrigal Pharmaceuticals. This classification means the drug is only dispensed through a curated network of specialty pharmacies. These pharmacies specialize in complex medications, provide patient support services, and typically ship directly to your home. You will not find Rezdiffra on the shelf at a retail chain.

Common specialty pharmacies that carry Rezdiffra include Accredo, CVS Specialty, Optum Specialty Pharmacy, and AllianceRx Walgreens Pharmacy. Which one you use often depends on your insurance plan's preferred pharmacy network.

Step 2: Enroll in Madrigal Patient Support — Do This First

Before anything else, enroll in Madrigal Patient Support. This program is the gateway to getting Rezdiffra dispensed through the specialty pharmacy system. Your prescriber's office can enroll you, or you can call directly:

Phone: 877-219-7770

Website: madrigalpharma.com/patient-support

Madrigal Patient Support helps coordinate prior authorization with your insurance, connects you to a specialty pharmacy in your network, and can enroll you in the Rezdiffra Copay Savings Card program. Enrolling early — ideally the same day your prescription is written — can shave days off your wait time.

Step 3: Complete Prior Authorization

Most insurance plans require prior authorization (PA) before they will cover Rezdiffra. This is one of the biggest sources of delay. Here is what your doctor typically needs to submit:

Liver biopsy results confirming NASH/MASH with F2 or F3 fibrosis

Documentation of current diagnosis and severity

Statement that the patient is using Rezdiffra alongside diet and exercise changes

Prescriber information and National Provider Identifier (NPI) number

If your PA is denied, your doctor can request a peer-to-peer review or file an appeal. First-time denials are common with new specialty drugs and are frequently overturned on appeal.

Step 4: Work with the Specialty Pharmacy

Once your PA is approved, the specialty pharmacy will contact you to verify your insurance, confirm your copay assistance enrollment, and set up shipping. Here is what to expect:

The pharmacy will verify your insurance coverage and any copay card eligibility

They will confirm your shipping address and preferred delivery window

Rezdiffra ships directly to your home — you do not need to pick it up

Ask about 90-day supply options — some plans allow this and can reduce per-fill costs

What If You Don't Have Insurance?

Without insurance, Rezdiffra costs approximately $3,950–$4,116 per month. However, Madrigal Pharmaceuticals offers a Patient Assistance Program for uninsured or underinsured patients who meet income eligibility requirements. If you qualify, you may receive Rezdiffra at no cost or significantly reduced cost. Contact Madrigal Patient Support at 877-219-7770 to learn if you qualify.

Tools to Help You Track Down Rezdiffra

Because Rezdiffra is a specialty-only drug, standard pharmacy lookup tools like GoodRx won't show retail availability. However, these resources can help:

Madrigal Patient Support (877-219-7770): Will identify which specialty pharmacy in your network carries the drug

Your insurance company's specialty pharmacy network: Call member services on the back of your insurance card to find in-network specialty pharmacies

GoodRx (goodrx.com/rezdiffra): May list specialty pharmacy pricing information

medfinder (medfinder.com): Calls pharmacies near you to find which ones can fill your prescription — particularly useful if your specialty pharmacy situation is unclear

How Long Will It Take?

If everything goes smoothly — prior auth is approved quickly, your insurance covers Rezdiffra, and you enroll in Madrigal Patient Support immediately — some patients receive their first shipment within 5–10 business days. If there are PA delays or appeals, it may take 3–6 weeks. Being proactive about enrollment and following up frequently with your doctor's office and the specialty pharmacy makes a real difference.
