Details and state availability.

Levothyroxine T4 is a naturally circulating thyroid hormone produced by the canine thyroid gland. Levothyroxine sodium provided by Thyro-Tabs Canine tablets cannot be distinguished from levothyroxine endogenously secreted from the dog’s thyroid gland. Thyroid hormones influence virtually every body organ, either by their effect on growth and development or by the hormones’ metabolic effects.

In light of low canine bioavailability and high absorption variability among individual dogs, reliable dose potency becomes an essential tool toward successful therapy. Advanced Formula Thyro-Tabs Canine is the only veterinary levothyroxine sodium tablet to provide a minimum 95% dose potency guarantee, as recognized by the USP. As such, Thyro-Tabs Canine sets a new therapeutic standard in the treatment of canine hypothyroidism.

For oral use in dogs only.

  • First and Only FDA approved canine T4 brand
  • First and Only canine T4 brand to achieve Higher USP tablet Standard
  • First and Only canine T4 delivers 24-month dose stability

Product Form

Thyro-Tabs Canine (levothyroxine sodium tablets), USP contains synthetic crystalline L-3,3’,5,5’- tetraiodothyronine sodium salt [levothyroxine (T4) sodium].

Synthetic T4 is identical to that produced in the canine thyroid gland.

The initial daily dose is 0.1 mg/10 pounds (0.01 mg/lb; 0.022 mg/kg) body weight as a single dose every 24 hours or as a divided dose every 12 hours. The dose may then be adjusted by monitoring the serum total thyroxine (TT4) concentrations 4 to 6 hours post-tablet administration, along with clinical response, of the dog every 4 to 8 weeks until an adequate maintenance dose is established. Due to potential differences in bio-availability, monitor serum TT4 concentrations and clinical response when switching from another levothyroxine sodium formulation to Thyro-Tabs Canine.

To minimize day-to-day variations in serum TT4 concentrations (see CLINICAL PHARMACOLOGY), owners should consistently administer Thyro-Tabs Canine either with or without food.
