The Westhroid shortage has lasted years with no clear end in sight. Here's the latest patient update for 2026—what happened, where things stand, and your options.

If you've been waiting for Westhroid to come back to your pharmacy's shelves, this update is for you. The Westhroid shortage has persisted since August 2020—one of the longest-running availability problems in the thyroid medication community. Here's everything you need to know as a patient in 2026.

What Is the Current Status of Westhroid in 2026?

As of 2026, Westhroid remains largely unavailable at most retail pharmacies in the United States. RLC Labs, the manufacturer, recalled all unexpired lots of its desiccated thyroid products in August 2020 due to sub-potency concerns. The company has been working on quality remediation, but has not announced a confirmed return date for Westhroid, Nature-Throid, or WP Thyroid.

Occasional reports surface of small amounts of Westhroid appearing at specific independent pharmacies, but availability is sporadic and inconsistent. Most patients and providers should not count on Westhroid being available at a given pharmacy without first checking.

Timeline: What Happened with Westhroid and RLC Labs

RLC Labs products (Nature-Throid, WP Thyroid) experienced periodic shortages and reports of reduced effectiveness from patients

RLC Labs issues voluntary recall of ALL unexpired lots of Nature-Throid and WP Thyroid due to sub-potency (T3/T4 as low as 87% of labeled amount)

RLC Labs works with quality consultants to remediate manufacturing processes. No new product released to market

Westhroid, Nature-Throid, and WP Thyroid continue to be largely unavailable. No official return to market announced

Why Did the Sub-Potency Recall Happen?

FDA testing found that certain lots of Nature-Throid and WP Thyroid contained as little as 87% of the labeled amount of liothyronine (T3) and levothyroxine (T4). For thyroid patients, even small variations in hormone potency can cause significant symptoms. Patients on sub-potent lots experienced the return of hypothyroid symptoms—fatigue, weight gain, hair loss, cold sensitivity—despite taking their prescribed dose faithfully.

RLC Labs responded by voluntarily recalling all unexpired product and beginning a quality overhaul. However, the process of bringing a pharmaceutical manufacturing operation back into full regulatory compliance takes significant time and investment.

What Should Patients Do Right Now?

If you are currently without Westhroid or expect to run out soon, take these steps:

Contact your doctor immediately — do not skip doses or stop your thyroid medication abruptly

Ask about switching to Armour Thyroid or NP Thyroid — both contain T3 + T4 and are available at most pharmacies

Ask your doctor about compounded NDT — compounding pharmacies can prepare a custom dose using Thyroid USP

Use medfinder to check if any pharmacies near you currently have Westhroid in stock

Is Westhroid Coming Back?

RLC Labs has stated they intend to return their products to market. However, no confirmed return date has been announced as of 2026. Given that the shortage has now lasted over five years, patients and providers should not make treatment plans dependent on Westhroid's return.

The thyroid patient community has been vocal and persistent in asking RLC Labs for updates, but the company has provided limited public communication about the timeline for resuming production.

Frequently Asked Questions

Yes. Westhroid has been largely unavailable since August 2020, when manufacturer RLC Labs recalled all lots of its desiccated thyroid products due to sub-potency. As of 2026, the company has not announced a confirmed return to market, and the drug remains very difficult to find at most pharmacies.

RLC Labs has not announced a confirmed date for resuming distribution of Westhroid, Nature-Throid, or WP Thyroid as of 2026. Patients should work with their doctors to identify available alternatives rather than waiting for a return date.

In rare cases, small quantities of Westhroid may appear at independent pharmacies. However, availability is sporadic and cannot be relied upon for consistent medication management. Using medfinder to check pharmacies near you is the most efficient way to determine current local availability.

Westhroid itself was not directly named in the August 2020 recall—the recall specifically covered Nature-Throid and WP Thyroid. However, because all three products are manufactured by RLC Labs, Westhroid's availability has been severely impacted by the same manufacturing quality remediation effort.
