0.22% (1.0 g) |
One level teaspoonful contains approximately 12 mg of T-4.

Indications: For use in horses for correction of conditions associated with low circulating thyroid hormone (hypothyroidism).
Dosage: The suggested initial dose is 0.5 to 3.0 mg levothyroxine sodium (T-4) per 100 pounds of body weight (1 to 6 mg per 100 kg) once per day or in divided doses. Response to the administration of Thyro-L should be evaluated clinically until an adequate maintenance dose is established. In most horses, this is usually in the range of 6 to 36 mg total daily dose of T-4. Serum T-3 and T-4 values can vary greatly among individual horses on thyroid supplementation. Dosages should be individualized and animals should be monitored daily for clinical signs of hyperthyroidism or hypersensitivity.
Administration: Thyro-L can be administered by mixing the daily dose in the concentrate or by top dressing on grain, preferably rolled or ground. To facilitate the proper adhesion of Thyro-L to the ration, slightly moisten the grain with water or liquid supplement.
Warning: Administer with caution to animals with clinically significant heart disease, hypertension or other complications for which a sharply increased metabolic rate might prove hazardous. Use in pregnant mares has not been evaluated.
Caution: Federal law restricts this drug to use by or on the order of a licensed veterinarian.
