Levothyroxine sodium therapy is contraindicated in thyrotoxicosis, acute myocardial infarction, and uncorrected adrenal insufficiency. Other conditions in which the use of L-thyroxine replacement therapy may be contraindicated or should be instituted with caution include primary hypertension, euthyroidism, and pregnancy.There are no side effects in most cases. There can be differences when the pet has a preexisting heart condition; consult a veterinarian regarding these risks.


The administration of levothyroxine sodium to dogs to be used for breeding purposes or in pregnant bitches has not been evaluated. There is evidence to suggest that administration to pregnant bitches may in some instances affect the normal development of the thyroid gland in the unborn pups.

Adverse Reactions:

There are no specific adverse reactions associated with levothyroxine sodium administration at the recommended dosages. Overdosage will result in the signs of thyrotoxicosis listed above under cautions.



It is important to follow your veterinarian's prescription instructions for your pet.
The initial recommended daily dose is 0.1 to 0.2 mg/10 pounds 4.5 kg body weight in single or divided doses. Dosage is then adjusted by monitoring the T-4 blood levels of the dog every four weeks until an adequate maintenance dose is established. The usual daily maintenance dose is 0.1 mg/10 lb 4.5 kg. A maximum of 0.8 to 1.0 mg total daily dose will be sufficient in most dogs over 80 pounds in body weight. 


Thyro-Tabs Caplets may be administered orally or placed in the food. 


Each Thyro-Tabs Tablet contains synthetic crystalline levothyroxine sodium, USP.
