Description:
Thyro-L Powder
Vet-A-Mix
Levothyroxine sodium powder supplement for
horses
Thyro-L is for use in horses for correction of conditions
associated with low circulating thyroid hormone (hypothyroidism).
Each pound (453.6 g) contains:
|
Levothyroxine Sodium USP |
0.22% (1.0 g) |
One level teaspoonful contains approximately 12 mg of T-4.
One level tablespoonful contains approximately 36 mg of T-4.
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.
