Thyro-tabs Canine is an FDA-approved preparation containing Thyro-tabs Canine, for veterinary use. Available by prescription.
Veterinarians consider Thyro-Tabs Canine when a patient presents with clinical signs associated with hypothyroidism—a condition characterized by an underactive thyroid gland. These signs commonly include lethargy, weight gain without an increase in food intake, skin changes and cold intolerance. By providing a exogenous source of thyroid hormone, your veterinarian can manage the patient's metabolic health and support the normal function of multiple organ systems that rely on adequate hormone levels.At a pharmacological level, levothyroxine sodium acts as a synthetic form of tetraiodothyronine (T4). In the body, T4 is a prohormone that is deiodinated by various tissues into its active form, triiodothyronine (T3). This active hormone binds to thyroid receptor proteins in the cell nucleus, which then modulate gene expression to regulate cellular metabolism, protein synthesis and oxygen consumption. Thyro-Tabs Canine acts to mimic the steady-state hormonal environment found in a healthy canine patient. Your veterinarian will determine whether this medication is appropriate based on diagnostic blood work, including total T4 and thyroid-stimulating hormone (TSH) concentrations, as well as the specific cardiovascular management needs of your pet.

Commonly observed effects associated with thyroid hormone replacement are typically related to the stabilization of the patient's metabolism. However, if hormone levels become higher than the physiological requirement, owners may watch for signs of hyperthyroidism, such as excessive thirst (polydipsia), frequent urination (polyuria), panting, hyperactivity or a significant increase in appetite accompanied by weight loss. Because thyroid hormones influence heart rate and metabolic demand, your veterinarian will monitor for blood pressure shifts and cardiac changes, especially during the initial phases of therapy.
This medication is typically used with extra caution or avoided in patients with uncorrected adrenal insufficiency (Addison's disease), acute myocardial infarction or certain cardiovascular disorders. It should be carefully discussed for patients with concurrent diabetes mellitus, as thyroid replacement may influence insulin requirements. Before starting a protocol involving Thyro-Tabs Canine, ensure your veterinarian has a complete history of all other prescriptions your pet is receiving, as certain medications can interfere with the absorption or metabolism of levothyroxine. Your veterinarian is the right person to design a comprehensive monitoring plan, which usually involves periodic blood testing to ensure the hormone levels remain within the target therapeutic range for your pet’s individual health status.
Yes. Thyro-Tabs Canine is a prescription medication and can only be dispensed by a licensed pharmacy upon receipt of a valid authorization from a licensed veterinarian. Mixlab verifies all authorizations before any medication is prepared or shipped.
While Thyro-Tabs Canine is a specific FDA-approved commercial tablet, Mixlab carries a full range of thyroid medications. If your veterinarian determines that a compounded formulation—such as an oral liquid or a specialized strength not available commercially—better suits your pet's needs, our compounding team can prepare that preparation with a valid prescription.
Levothyroxine sodium is the generic name for the active ingredient in Thyro-Tabs Canine, which veterinarians discuss for the management of hypothyroidism. It serves as a replacement for the natural thyroid hormone that the dog's body is unable to produce in sufficient quantities.
Veterinarians typically recommend periodic blood testing to monitor thyroid levels, often starting a few weeks after the medication begins or whenever a dose is changed. These diagnostic follow-ups allow your veterinarian to ensure the management plan remains appropriate for your pet's individual needs.
