Each tablet delivers 0.1 mg levothyroxine sodium, the lowest and smallest dose in the nine-strength Thyro-Tabs Canine line. While FDA-approved for dogs only, it is a commonly accepted veterinary practice to use this product in cats as well, particularly for post-thyroidectomy T4 supplementation. The 0.1 mg strength makes it the go-to starting option for the tiniest dogs, kittens, and small cats requiring precise low-dose thyroid supplementation.\u003c\/p\u003e\n\n\u003ch3\u003eBenefits\u003c\/h3\u003e\n\u003cul type=\"disc\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLowest Available Starting Dose:\u003c\/strong\u003e At 0.1 mg, this is the entry-level tablet strength, giving vets the most conservative starting point for toy breeds, small dogs, and cats.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSupports Feline Post-Surgical Use:\u003c\/strong\u003e Commonly used off-label in cats following surgical thyroid removal to replace T4 the gland can no longer produce.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRestores Metabolic Balance:\u003c\/strong\u003e Supplements deficient circulating thyroid hormone levels, helping restore the metabolic activity that supports normal energy, weight, skin, and coat.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValidated Clinical Results:\u003c\/strong\u003e A controlled US field study confirmed 75.6% of evaluable dogs achieved normalized TT4, fT4, and TSH concentrations by Day 182 of treatment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSigns of Hypothyroidism Improve:\u003c\/strong\u003e Weight gain, lethargy, hair thinning, skin thickening, hyperpigmentation, and elevated cholesterol showed improvement throughout the field study period.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScored for Precise Splitting:\u003c\/strong\u003e The yellow oval tablet is scored, allowing it to be split into a 0.05 mg half-dose when the vet needs an even lower starting point, particularly for cats.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIngredients\u003c\/h3\u003e\n\u003ch4\u003eActive Ingredients\u003c\/h4\u003e\n\u003cp\u003eLevothyroxine Sodium (Anhydrous): 0.1 mg per tablet\u003c\/p\u003e\n\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003ch4\u003eDosage and Administration Instructions\u003c\/h4\u003e\n\u003cul type=\"disc\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrescription Required:\u003c\/strong\u003e Federal (USA) law restricts Thyro-Tabs Canine to use by or on the order of a licensed veterinarian only.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDog Starting Dose:\u003c\/strong\u003e 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 as directed by the vet.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCat Off-Label Dose:\u003c\/strong\u003e The typical feline dose is 0.05 mg to 0.1 mg per cat once daily; the exact amount is set by the veterinarian based on the individual cat's needs and bloodwork.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOff-Label Cat Use Disclosure:\u003c\/strong\u003e Thyro-Tabs Canine is FDA-approved for dogs only; use in cats is a commonly accepted off-label veterinary practice and must be directed by a licensed vet.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePost-Dose Monitoring Window:\u003c\/strong\u003e Collect blood for serum TT4 measurement 4 to 6 hours after the tablet to capture peak absorption levels for the most accurate dose assessment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecheck Bloodwork Every 4-8 Weeks:\u003c\/strong\u003e Reassess serum TT4 and clinical signs at 4 to 8 week intervals until the maintenance dose is confirmed as stable for the individual pet.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSame Food Routine Every Day:\u003c\/strong\u003e Give consistently with food or consistently without; changing this daily will cause unpredictable T4 absorption that undermines reliable dose management.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTell the Vet About All Medications:\u003c\/strong\u003e Many drugs including vitamins, minerals, herbal supplements, and other prescriptions can interact with levothyroxine; a complete medication list is essential.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDisclaimer:\u003c\/strong\u003e This dosage information is provided by the manufacturer.

In cats, it is commonly used off-label — especially following surgical thyroid removal — to restore T4 levels the gland can no longer produce on its own, under direct veterinary supervision.\u003c\/p\u003e\n\n\u003ch3\u003eQ2: What is the correct Thyro-Tabs 0.1 mg dose for cats?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e When used off-label in cats, the typical dose is 0.05 mg to 0.1 mg per cat once daily, as directed by the veterinarian. The scored tablet allows a clean split into 0.05 mg halves. The exact amount and schedule must always be set by the prescribing vet based on the individual cat's bloodwork and health status.\u003c\/p\u003e\n\n\u003ch3\u003eQ3: Why is the 0.1 mg yellow tablet the most appropriate Thyro-Tabs strength for cats?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e Cats typically need far less daily levothyroxine than dogs, with most feline doses falling between 0.05 mg and 0.1 mg per cat rather than weight-based increments. The 0.1 mg tablet is the only strength low enough to deliver an accurate single feline dose, and can be split to 0.05 mg for cats needing even less.\u003c\/p\u003e\n\n\u003ch3\u003eQ4: Is Thyro-Tabs Canine 0.1 mg levothyroxine safe for cats with heart disease?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e Thyro-Tabs must be used with caution in any cat or dog with underlying heart disease. Levothyroxine raises metabolic demands, which can add strain to a compromised heart. Close veterinary monitoring throughout the entire dose-establishment phase is essential for all cardiac patients starting thyroid hormone replacement.\u003c\/p\u003e\n\n\u003ch3\u003eQ5: What happens if a dog or cat accidentally ingests extra Thyro-Tabs 0.1 mg tablets?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e Accidental ingestion of excess levothyroxine can cause signs of over-supplementation including rapid breathing, restlessness, vomiting, increased thirst, and collapse. Contact your veterinarian or an emergency animal clinic immediately if you suspect your pet has ingested more than the prescribed amount of this thyroid supplement.\u003c\/p\u003e\n\u003ch2\u003eClinical Research\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.msdvetmanual.com\/endocrine-system\/the-thyroid-gland\/hypothyroidism-in-animals\" title=\"Hypothyroidism in animals - endocrine system - msd veterinary manual\" aria-label=\"Visit a webpage about Hypothyroidism in animals - endocrine system - msd veterinary manual\"\u003e\u003cspan\u003ehttps:\/\/www.msdvetmanual.com\/endocrine-system\/the-thyroid-gland\/hypothyroidism-in-animals\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.petmd.com\/dog\/conditions\/endocrine\/c_dg_hypothyroidism\" title=\"Hypothyroidism in dogs | petmd\" aria-label=\"Visit a webpage about Hypothyroidism in dogs | petmd\"\u003e\u003cspan\u003ehttps:\/\/www.petmd.com\/dog\/conditions\/endocrine\/c_dg_hypothyroidism\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/dailymed.nlm.nih.gov\/dailymed\/fda\/fdaDrugXsl.cfm?setid=38005382-289a-4293-b58e-b1cda8bc2288#:~:text=INDICATION%3A%20For%20replacement%20therapy%20for,divided%20dose%20every%2012%20hours\"\u003e\u003cspan\u003ehttps:\/\/dailymed.nlm.nih.gov\/dailymed\/fda\/fdaDrugXsl.cfm?setid=38005382-289a-4293-b58e-b1cda8bc228\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lloyd","offers":[{"title":"1 tablet","offer_id":41772370362529,"sku":"004036-1","price":1.0,"currency_code":"GBP","in_stock":true},{"title":"30 tablets","offer_id":44489407332513,"sku":"004036-30","price":2.0,"currency_code":"GBP","in_stock":true},{"title":"60 tablets","offer_id":44489407365281,"sku":"004036-60","price":4.0,"currency_code":"GBP","in_stock":true},{"title":"120 tablets","offer_id":41772370329761,"sku":"004036","price":7.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0593\/2446\/5313\/files\/thyro-tabs-levothyroxine-sodium-for-dogs-cats-0-1-mg-30-tablets-913.jpg?v=1778195158","url":"https:\/\/hardypaw.com\/en-gb\/products\/thyro-tabs-for-dogs-cats-0-1-mg","provider":"HardyPaw","version":"1.0","type":"link"}
