Thyrocryn and ThyroKare Dog Thyroid Tablets Recalled for Low Potency

Agency Publication Date: November 13, 2023

Summary

Neogen Corporation is recalling 3,861 bottles of Thyrocryn and ThyroKare (levothyroxine sodium tablets) used to treat hypothyroidism in dogs. The recall was initiated because testing showed the medication was subpotent, meaning it contains less of the active ingredient than required. If your dog is taking this medication, contact your veterinarian to discuss alternative treatment options and return any remaining tablets to the place of purchase for a refund or throw them away.

Risk

The tablets may not provide the full prescribed dose of thyroid hormone, which could result in the ineffective treatment of a dog's hypothyroidism and the return of symptoms like lethargy, weight gain, or skin issues.
