  • INDICATIONS & USAGE

    Indications: For use in horses for correction of conditions associated with low circulating thyroid hormone (hypothyroidism).

  • DOSAGE & ADMINISTRATION

    Dosage: The suggested initial dose is 0.5 to 3.0mg levothyroxine sodium (T-4) per 100 lbs of body weight (1 to 6 mg per 100 kg) once per day or in divided doses. Response to the administration of Levothyroxine powder should be evaluated clinically until an adequate maintenance dose is established. In most horses, the total daily dose of T-4 is in the range of 6 to 36 mg. Serum T-3 and T-4 values can vary greatly among individual horses on thyroid supplementation. Doses should be individualized and animals should be monitored daily for clinical signs of hyperthyroidism or hypersensitivity.


    Administration: Levothyroxine powder can be administered by mixing the daily dose in the concentrate or by top dressing on the grain, preferably rolled or ground. To facilitate the proper adhesion of Levothyroxine powder to the ration, slightly moisten the grain with water or a liquid supplement.
