Sign in to monitor this recall

Summary

Lloyd Inc. of Iowa is recalling approximately 159,443 containers of Thyro-L (levothyroxine sodium powder), a medication used for horses with thyroid conditions. The recall affects 143,367 of the 1-pound containers and 16,076 of the 10-pound containers distributed nationwide in the USA and in Ontario, Canada. The product was found to be 'out of specification' for low potency, meaning the medication may not be strong enough to provide the intended therapeutic effect for the animal's health within its labeled shelf life.

Risk

The lower-than-expected potency of the levothyroxine sodium may lead to ineffective treatment of thyroid conditions in horses. This could result in the animal not receiving the correct dosage required to manage its condition, potentially leading to persistent or worsening symptoms of hypothyroidism.

  2. If you have animal health concerns, contact your veterinarian.
  3. Return any unused product to the place of purchase for a refund, throw it away, or contact the manufacturer or supplier for further instructions.
  4. Call the FDA Consumer Complaint hotline at 1-888-723-3332 if you have additional questions or wish to report a problem.
