Low-Dose Daily Thyroid Supplement Tablet for Small Hypothyroid Dogs Product Description Thyro-Tabs Canine (Levothyroxine Sodium Tablets, USP) 0.2 mg is an FDA-approved prescription thyroid hormone replacement for dogs, supplied as light pink scored oval tablets in bottles of 120 or 1,000. Each tablet contains 0.2 mg levothyroxine sodium, the second-lowest strength in the nine-tablet Thyro-Tabs Canine line. It provides synthetic T4 chemically identical to what a healthy canine thyroid produces and is indicated for replacement therapy of diminished thyroid function in dogs. Best suited to small-breed dogs or those whose bloodwork and body weight call for a low daily dose of T4 supplementation. Benefits Purpose-Built for Small Dogs: The 0.2 mg dose sits just above the lowest available strength, giving the vet a precise low-dose option for small breeds without over-supplementing. Field Study Proven: A US controlled field study showed 75.6% of evaluable dogs achieved normalized TT4, fT4, and TSH concentrations by Day 182 on Thyro-Tabs Canine. Addresses Key Clinical Signs: Lethargy, weight changes, poor coat quality, skin thickening, hyperpigmentation, and elevated blood cholesterol all showed improvement during the field study period. Once or Twice Daily Administration: The full daily dose can be given as a single oral tablet every 24 hours or split into two equal administrations every 12 hours. Scored for Dose Precision: The light pink tablet is scored, allowing it to be split cleanly into two 0.1 mg halves when the vet needs to fine-tune the starting or maintenance dose. Consistent Manufacturing Quality: Produced under the same FDA manufacturing standards and in the same facilities as the human levothyroxine formulation for reliable tablet-to-tablet potency. Ingredients Active Ingredients Levothyroxine Sodium (Anhydrous): 0.2 mg per tablet How to Use Dosage and Administration Instructions Prescription Required: Federal (USA) law restricts Thyro-Tabs Canine to use by or on the order of a licensed veterinarian only. Weight-Based Starting Dose: Begin at 0.1 mg per 10 lbs (0.022 mg/kg) once every 24 hours, or divided equally into two doses every 12 hours under veterinary direction. Optimal Blood Draw Timing: Always collect the serum TT4 sample 4 to 6 hours after giving the tablet to capture the most accurate peak-absorption hormone reading. Scheduled Monitoring Visits: Return for clinical reassessment and TT4 bloodwork every 4 to 8 weeks until the dog reaches a confirmed, stable maintenance dose. Consistent Daily Routine: Give the tablet at the same time each day with the same food routine; predictable timing helps keep serum T4 steady between monitoring visits. Do Not Self-Adjust: Never change the tablet dose, frequency, or brand without consulting the prescribing vet; even small changes can shift T4 levels enough to cause problems. Expect Long-Term Use: Hypothyroidism in dogs is a chronic condition; plan for ongoing daily tablet administration and routine veterinary monitoring as a permanent part of the dog's health care. Disclaimer: This dosage information is provided by the manufacturer. Always consult your veterinarian before administering or adjusting any supplement for your pet. Additional Information Precautions Thyrotoxicosis Contraindicated: Thyro-Tabs must not be given to any dog where excess circulating thyroid hormone has already been identified or confirmed by the vet. Adrenal Status Check: Correct any existing adrenal insufficiency before introducing thyroid hormone replacement to avoid triggering a serious hormonal imbalance. Cardiac Patient Caution: Dogs with pre-existing heart conditions require particularly close vet monitoring throughout the entire dose-establishment phase of treatment. Cardiac Drug Dose Review: Both levothyroxine and any concurrent heart medication may need dose adjustments based on the dog's clinical response once thyroid replacement begins. Breeding and Reproductive Animals: Safe use in breeding males, pregnant females, or lactating mothers has not been established; always consult the vet before use in these dogs. Drug Interaction Awareness: Corticosteroids, anticonvulsants, and certain supplements can all alter levothyroxine uptake; review the dog's full medication list with the vet before starting. Possible Side Effects Itching (Pruritus): Post-approval adverse drug experience data for Thyro-Tabs Canine consistently identifies pruritus as the most frequently reported adverse reaction in treated dogs. T4 Outside Normal Range: Both high and low serum TT4 readings feature among the most commonly submitted post-approval adverse events; scheduled monitoring identifies these changes early. Digestive Changes: Vomiting, diarrhea, and reduced appetite were documented in both field study participants and through ongoing post-approval adverse event submissions. Increased Drinking and Urination: Polydipsia and polyuria have appeared in post-approval reports and should be flagged to the vet if they develop following a dose change. Liver Enzyme Elevations: Three dogs in the field study showed raised ALP, ALT, or AST; the majority normalized spontaneously before the study concluded without medication changes. Hypersensitivity Reactions: Post-approval experience includes reports of urticaria, facial swelling, alopecia, seborrhea, and dermatitis; contact the vet if any of these develop. Storage Information Room Temperature Storage: Store at 20-25°C (68-77°F); brief excursions between 15-30°C (59-86°F) are acceptable and will not compromise tablet integrity or potency. Light and Moisture Protection: Keep the original bottle tightly sealed and away from direct sunlight and humid environments to maintain levothyroxine sodium stability over the shelf life.

Ans: Thyro-Tabs Canine 0.2 mg is an FDA-approved prescription oral thyroid replacement for small dogs diagnosed with hypothyroidism. It supplements the deficient T4 hormone the thyroid can no longer produce adequately, helping restore the metabolic balance needed for healthy energy levels, normal weight, and good coat condition. Q2: Which dogs are best suited to the Thyro-Tabs 0.2 mg strength? Ans: The 0.2 mg light pink tablet is typically suited to small-breed dogs whose body weight and initial weight-based dose calculation or early serum TT4 monitoring results indicate a low daily T4 requirement. The prescribing vet determines whether this strength is right after reviewing the dog's blood results and clinical signs. Q3: How often does a dog on Thyro-Tabs levothyroxine need blood monitoring? Ans: Until a stable maintenance dose is confirmed, TT4 levels should be rechecked every 4 to 8 weeks. Blood must always be drawn 4 to 6 hours after the dose to capture peak absorption. Once the dose is stable, monitoring frequency can be reduced to every 3 to 6 months as directed by the veterinarian. Q4: Can the Thyro-Tabs 0.2 mg dog thyroid tablet be given to cats? Ans: Thyro-Tabs Canine is labeled for use in dogs only. Use in cats is considered off-label. While some vets may prescribe levothyroxine to cats, particularly following thyroid surgery, this would be outside the FDA-approved indication and should only be done under explicit veterinary direction and supervision. Q5: What happens if a dose of Thyro-Tabs levothyroxine sodium is accidentally skipped? Ans: If a dose is missed, give it as soon as it is noticed unless it is almost time for the next scheduled dose; in that case, skip the missed dose and continue with the regular schedule. Never give two doses at once to make up for a missed one, and notify the vet if doses are being missed frequently as this disrupts T4 stability.
