Thyrocryn and ThyroKare Dog Tablets Recalled for Low Potency

Sign in to monitor this recall

Summary

Neogen Corporation is recalling Thyrocryn and ThyroKare (levothyroxine sodium) tablets, 0.2 mg, used to treat hypothyroidism in dogs. Stability testing revealed that one batch of the medication was subpotent, meaning it contained less of the active ingredient than required, and additional batches are being removed as part of an investigation. Low potency medication can lead to under-treatment of a dog's thyroid condition.

Risk

The tablets may not provide the full dose of levothyroxine sodium required to manage a dog's thyroid condition, potentially leading to persistent symptoms of hypothyroidism. No incidents or injuries have been reported to date.

What You Should Do

  1. Check your dog's medication bottle for the brand names Thyrocryn or ThyroKare (0.2 mg tablets) and verify the lot numbers and expiration dates.

  3. 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.
