Armour Thyroid Availability – FDA Update
Many patients searching for information on Armour Thyroid UK availability have concerns following a recent announcement from the U.S. Food and Drug Administration (FDA). The FDA confirmed that Armour Thyroid (and NP Thyroid), an animal-derived thyroid medication, is considered unapproved and may be removed from the market in the future.
What the FDA Has Said About Armour Thyroid
On 6 August 2025, the FDA sent warning letters to manufacturers and distributors of Armour Thyroid. This medication, made from pig thyroid glands, contains both T4 (thyroxine) and T3 (triiodothyronine). Since it has not undergone modern safety and efficacy reviews, the FDA plans to enforce its removal in 12 months. While Armour Thyroid UK availability remains for now, the long-term future is uncertain.
The Future of Armour Thyroid
Considering the FDA’s position and the requirement that AbbVie must register Armour Thyroid as a biologic by 2029, it is expected that Armour will either become unavailable or prohibitively expensive. Armour Thyroid is already costly, and this regulatory change will likely increase its price substantially, making it less accessible for many patients in the UK.
Our Recommendation for Patients on Armour Thyroid
If you currently use Armour Thyroid, there is no need to panic, but it’s wise to prepare:
- Discuss your treatment plan with your healthcare provider and have an alternative ready.
- Stock up carefully. Armour Thyroid has an expiration date of over one year. Keeping a one-year supply on hand may help reduce anxiety about potential shortages.
- Consider switching from Armour Thyroid to Liothyronine. If levothyroxine has not worked for you, liothyronine is a recommended alternative. Studies show that liothyronine therapy normalizes thyroid hormone levels effectively with minimal side effects (read study). Although it can be costly in the UK, it is available internationally at more reasonable prices.
- Have faith in supply continuity. There will always be sources of natural desiccated thyroid (NDT). If not from the U.S., other countries will likely meet demand if needed.
