View Thyro L Drug Facts Sheet.

The suggested initial dose is 0.5 to 3.0 mg levothyroxine sodium (T-4) per 100 pounds body weight (1 to 6 mg per 100 kg) once per day or in divided doses. The recommended daily dose is 1/2 to 2 1/2 level teaspoons for a 500 kg (1,100 lb) horse.

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 (1/2 to 3 level teaspoons) 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 proper adhesion of Thyro-L to the ration, slightly moisten the grain with water or liquid supplement.

Thyro-L can be administered by mouth or in the feed at a dosage of 48 mg (4 tsp) per day for 3-6 months to induce weight loss. Smaller ponies and Miniature horses can receive 24 mg/day for the same time period. Treated horses should be weaned from Thyro-L once ideal weight has been attained by reducing the dosage to 24 mg (2 tsp) for 1 week, followed by 12 mg (1 tsp) per day for an additional 2 weeks.

Caution:

Federal law restricts this drug to use by or on the order of a licensed veterinarian.

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.
