Thyrocryn and ThyroKare Dog Thyroid Tablets Recalled for Low Potency

Agency Publication Date: September 22, 2022

Summary

Neogen Corporation is recalling approximately 5,284 bottles of Thyrocryn and ThyroKare (levothyroxine sodium) tablets used to treat low thyroid levels in dogs. The recall was initiated because the products are subpotent, meaning they do not contain the full labeled amount of active medication. No illnesses or injuries have been reported to date. These tablets were distributed nationwide in the USA and Guam through veterinary clinics, pharmacies, and authorized distributors.

Risk

Because the tablets are subpotent, dogs may not receive the intended dose of medication, which can lead to ineffective treatment of hypothyroidism. This may result in the recurrence of symptoms like lethargy, weight gain, or skin issues.

What You Should Do

Check your dog's medication for the following brands: Thyrocryn or ThyroKare (levothyroxine sodium tablets), 0.1 mg, in either 180-count or 1,000-count bottles.
Inspect the bottle label for the following lot numbers: BM0120221T, BM0526211T, BM0808221T, BM0120221Z, BM0526211Z, or BM0808221Z. See the Affected Products section below for the full list of affected codes.
If you have animal health concerns, contact your veterinarian. Return any unused product to the place of purchase for a refund, throw it away, or contact the manufacturer or supplier for further instructions.
