Thyro-Tabs® Tablets for Canine Hypothyroidism

Thyro-Tabs® is the veterinary levothyroxine sodium tablet used to treat hypothyroidism in dogs. This page explains what it is, how it works, and how to use it safely for your pet. We offer Canadian pricing with US delivery from Canada, so you can compare costs and order even if you pay without insurance.

What Thyro-Tabs® Is and How It Works

Thyro-Tabs® contains levothyroxine sodium, a synthetic form of the canine thyroid hormone T4. In hypothyroid dogs, the thyroid gland does not produce enough hormone. Supplementing T4 restores normal metabolism, energy, skin and coat quality, and body weight over time.

At CanadianInsulin, orders are filled by licensed Canadian pharmacies after we confirm a valid prescription with your clinic. Your pet’s medication ships from Canada to the US through our referral network.

After your veterinarian selects a dose, levothyroxine is absorbed from the gut and converted in the body to T3, the active hormone. It supports normal cellular function across many organs, including the skin, heart, and nervous system.

Who Thyro-Tabs® Is For

Thyro-Tabs is for dogs diagnosed with primary hypothyroidism. Common signs include lethargy, weight gain, cold intolerance, hair loss, and skin changes. A veterinarian confirms the diagnosis with blood tests before starting therapy.

Dogs with untreated adrenal disease, certain heart conditions, or severe systemic illness may need additional evaluation before starting therapy. Use caution in senior dogs or those with cardiac disease. Thyro-Tabs is not for dogs with hyperthyroidism.

Dosage and Usage

Veterinarians typically begin with a weight-based dose. A common starting schedule is about 0.1 mg per 10 lb (0.022 mg/kg) of body weight given twice daily. Your veterinarian may later adjust the dose and frequency based on T4 levels and clinical response. Some dogs can transition to once-daily dosing; others need twice daily for consistent control.

Give tablets at the same times each day. Be consistent with food timing. Many clinicians recommend giving on an empty stomach or in a consistent manner with meals. Your clinic will advise blood test timing, often 4 to 6 hours after dosing, to check serum T4 and fine-tune therapy. Follow your veterinarian’s instructions for Thyro Tabs for Dogs Dosage.

Strengths and Forms

Thyro-Tabs is supplied as scored oral tablets in multiple strengths to fit a wide range of canine sizes. Availability may vary by pharmacy and strength.

• Common options include Thyro-Tabs 0.2 mg Tablets, Thyro Tabs 0.3 mg for Dogs, and Thyro Tabs 0.4 mg Tablets.

Many owners look for Levothyroxine for Dogs Tablets in specific sizes, such as Levothyroxine Sodium for Dogs 0.6 mg. If your veterinarian prescribes a specific size, you can compare the Thyro-Tabs 0.6 mg price or ask about Thyro-Tabs 0.6 mg from Canada options. Listings like Thyro-Tabs 0.6 mg Tablets Canada reflect Canadian pricing that may help with budgeting.

Missed Dose and Timing

If a dose is missed, give it when remembered unless it is close to the next scheduled dose. In that case, skip the missed dose and resume the regular schedule. Do not double up doses. Consistent timing helps maintain steady hormone levels and more reliable blood test interpretation.

Storage and Travel Basics

Store tablets at controlled room temperature in the original container. Keep them dry, tightly closed, and away from light. Avoid humid areas such as bathrooms. Keep out of reach of children and other pets.

For trips, pack extra tablets in the labeled vial. Carry a copy of the prescription or clinic contact information. If your dog takes other routine preventatives, consider organizing those together. Many pet owners align monthly preventatives such as Interceptor® Flavour Tabs Cats Dogs with their thyroid refill plan for convenience while traveling.

Benefits

When dosed and monitored appropriately, levothyroxine replacement can:

• Restore energy, alertness, and activity level
• Support weight normalization over time
• Improve coat density, shine, and reduce shedding
• Help resolve skin thickening and recurrent infections
• Support normal heart rate and metabolic function
• Provide steady, predictable hormone levels with consistent dosing

Thyro-Tabs tablets are scored, which helps veterinarians fine-tune doses for different body weights.

Side Effects and Safety

Most dogs tolerate levothyroxine well at appropriate doses. Possible side effects can reflect too much thyroid hormone or sensitivity during dose changes.

• Restlessness or hyperactivity
• Increased thirst, urination, or appetite
• Panting or elevated heart rate
• Vomiting or diarrhea
• Behavior changes such as nervousness

Serious or rare effects can include arrhythmias, excessive weight loss, or seizures in predisposed dogs. Report unusual signs to your veterinarian. If vomiting occurs, your clinic may address nausea; see our educational article on Cerenia Tablets for general information about that class of therapy.

Drug Interactions and Cautions

Some medications and supplements can reduce levothyroxine absorption or change how it is processed:

• Antacids, calcium, iron, and sucralfate can bind levothyroxine in the gut
• Cholestyramine and certain fiber supplements may reduce absorption
• Phenobarbital and some anticonvulsants can increase metabolism
• High-calcium or high-soy diets may alter absorption; keep a consistent diet plan

Dogs with heart disease may need cautious dosing and close monitoring. Discuss any concurrent cardiac therapy, including products like Vetmedin®, with your veterinarian so the plan is coordinated.

If your dog needs antibiotics or other medicines alongside thyroid therapy, coordinate timing and monitoring with your clinic. For background reading on common veterinary antibiotics, see Cephalexin For Dogs.

What to Expect Over Time

Energy and attitude often improve within the first one to two weeks after starting therapy. Skin and coat changes take longer. Many dogs show visible coat improvement over a few months as new hair cycles in.

Your veterinarian will typically recheck T4 levels after a couple of weeks on the starting dose and again after any change. Stable dogs move to periodic monitoring thereafter. For broad context on managing chronic conditions in pets, you can review our article on Arthritis In Dogs.

Compare With Alternatives

Veterinary levothyroxine tablets like Thyro-Tabs are the standard of care for canine hypothyroidism. In some cases, a veterinarian may recommend a different veterinary-labeled levothyroxine product or a compounded formulation to meet specific dose needs. Oral solutions exist in some markets. Your clinician will guide any change in brand or form and will recheck T4 levels after switching.

Availability and Substitutions

Strength availability can vary by pharmacy and supply. If a specific strength is temporarily unavailable, your veterinarian may select a different strength or an alternative brand and adjust the schedule to deliver the intended total daily dose. Any changes should be monitored with follow-up T4 testing.

Patient Suitability and Cost Saving Tips

Good candidates are dogs with confirmed hypothyroidism based on clinical signs and lab testing. Extra caution is appropriate for dogs with heart disease, diabetes, or concurrent endocrine problems. Pregnant or lactating dogs require careful veterinary oversight.

• Ask your clinic about multi-month fills to reduce per-fill costs
• Keep the dose and brand consistent to avoid re-testing sooner than needed
• Use a pill organizer and a written schedule to avoid missed doses
• Set calendar reminders for lab rechecks and refills
• Review diet consistency to support steady absorption

Owners who manage multiple chronic therapies often align schedules with other long-term treatments. For example, see our overview on allergy therapy in Apoquel For Dogs for context on coordinating daily medications.
