What Is Being Recalled
A nationwide recall has been reported for one lot of Thyroid Tablets USP 30 mg, a porcine-derived thyroid medication containing levothyroxine and liothyronine. The product identifiers are NDC 69680-166-00, lot 504950, and an expiration date of 09/30/2026. The record describes 3,655 bottles distributed nationwide between January 31 and September 30, 2025.
The stated reason is potential superpotency, meaning the tablets may contain more active thyroid hormone than their labeled strength. Because the recall concerns a specific lot, the lot number and expiration date printed on a bottle matter. This notice does not establish that any individual patient has taken an excessive dose.
Why Excess Thyroid Hormone Matters
Thyroid hormone above what a patient needs can produce symptoms resembling an overactive thyroid. These may include palpitations, a rapid heart rate, tremor, sweating, insomnia, and nervousness. People with cardiac disease are particularly vulnerable to serious heart rhythm problems, so new symptoms in this group deserve prompt attention.
What Patients Should Do Now
Do not stop, skip, or change your thyroid medication on your own. Abrupt changes can also cause problems, and any adjustment should be made under medical guidance. Instead, contact your prescriber or pharmacist promptly. Tell them the product name and the lot number you have, and ask whether your supply is affected and what to do next. This is worth doing even if you feel well.
Seek urgent care right away if you develop chest pain, fainting, severe shortness of breath, a racing or irregular heartbeat that does not settle, or confusion. These symptoms should not wait for a routine appointment.
Confirming Recall Status
Recall status and identifiers can change, so they should be verified before you act on them. Confirm the current status with your pharmacist, or review the FDA or manufacturer notice for the most recent details. Readers who want wider context may also find a recent prescription-drug recall useful, along with a medication regulatory explainer.
Until the affected lot is confirmed through a pharmacist or an official notice, careful attention to lot numbers, expiration dates, and symptoms is advisable.
