Sign in to monitor this recall

Summary

Neogen Corporation is recalling approximately 3,900 bottles of Thyrocryn and ThyroKare (levothyroxine sodium tablets), USP, 1.0 mg, used to treat hypothyroidism in dogs. The recall was initiated because testing showed the tablets are subpotent, meaning they contain less of the active ingredient than required. The affected products were sold in 180-count and 1,000-count bottles across several states including Florida, Texas, and New York. To date, no injuries or adverse health events have been reported in connection with these products.

Risk

Low potency medication can lead to under-treatment of a dog's thyroid condition. If a dog does not receive the intended dose of levothyroxine sodium, their hypothyroid symptoms may not be properly managed or could return.

What You Should Do

  1. Check your dog's medication bottle for the brand names Thyrocryn or ThyroKare (1.0 mg strength).
  2. Look for the following batch numbers and expiration dates: Batch BZ0317221 (Exp. 09/17/23) or Batch BZ1024221 (Exp. 04/24/24).
  3. Verify the NDC numbers on the label: 46066-098-38 or 46066-098-35 for Thyrocryn; 59051-9126-0 or 59051-9126-8 for ThyroKare.
  4. 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.
  5. Call the FDA Consumer Complaint hotline at 1-888-723-3332 if you have additional questions regarding this recall.
