A practical guide for providers managing patients affected by the Adthyza discontinuation. Includes transition strategies and availability tools.
You're likely fielding calls from patients who can't fill their Adthyza prescriptions. Since Azurity Pharmaceuticals discontinued Adthyza in November 2025, patients dependent on this natural desiccated thyroid (NDT) medication have been left without their preferred treatment — and they're looking to you for answers.
This guide provides actionable steps your practice can take to help patients transition smoothly, find alternative medications in stock, and maintain continuity of care during a turbulent time for the NDT drug class.
Let's start with the facts:
Understanding the systemic issues helps you counsel patients effectively:
The NDT market has shrunk dramatically. With Nature-Throid, WP Thyroid, and now Adthyza gone, only two commercial NDT manufacturers remain (AbbVie and Acella). This concentration means any production or distribution hiccup has outsized impact on supply.
The FDA's August 2025 decision to remove all DTE products and reclassify them as biologics has created a chilling effect. Manufacturers face significant uncertainty about whether continued NDT production is economically viable, which affects investment in supply chain and inventory.
Even when NDT products are being manufactured, distribution isn't uniform. Chain pharmacies may have allocation limits, and wholesale distributors may prioritize higher-volume medications. This creates geographic pockets where NDT is readily available alongside areas where it's nearly impossible to find.
Every patient who was taking Adthyza (and before that, Nature-Throid and WP Thyroid) has shifted to the remaining options. This increased demand on a shrinking supply creates pressure at every pharmacy.
Run a query in your EHR for all patients with active Adthyza prescriptions. Don't wait for them to call — reach out proactively to schedule transitions. This prevents medication lapses and reduces last-minute emergency calls to your office.
Create a standardized approach for your practice:
Direct your staff and patients to Medfinder for Providers — a real-time pharmacy availability tool that shows which pharmacies near the patient currently have their medication in stock. This eliminates the frustrating cycle of calling pharmacy after pharmacy.
Additional sourcing tips to share with patients:
If switching a patient from Adthyza to another NDT product, their insurance may require a new prior authorization. Don't wait for the denial — submit PAs proactively with documentation including:
Ensure your clinical staff — including nurses, medical assistants, and pharmacy liaisons — understand the Adthyza discontinuation and your practice's transition protocol. Common patient questions and their answers:
While many patients have strong preferences for NDT, certain situations may warrant transitioning to synthetic options:

The Adthyza discontinuation is one piece of a larger disruption to NDT access that will likely intensify through 2026 and beyond. The providers who come through this well will be those who plan ahead, communicate proactively with patients, and have flexible prescribing strategies ready.
