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. Warnings: 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.


The clinical effects of levothyroxine sodium therapy are slow in being manifested. Overdosage of any thyroid drug may produce the signs and symptoms of thyrotoxicosis including, but not limited to: polydipsia, polyuria, polyphagia, reduced heat tolerance and hyperactivity or personality change. Thyro-Tabs® 0.7 mg caplets contain FD&C Yellow #5 tartrazine which has been associated with allergic-type reactions including bronchial asthma in susceptible humans. It is unknown whether such a reaction could also occur in other animals.

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.


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. How Supplied: Thyro-Tabs® levothyroxine sodium tablets, USP is available as scored, color-coded caplets in 9 concentrations: 0.1 mg - yellow 0.2 mg - pink 0.3 mg - green 0.4 mg - maroon 0.5 mg - white 0.6 mg - purple 0.7 mg - orange 0.8 mg - blue 1.0 mg - tan in bottles of 120 and 1000.
