It is the most common endocrine disease in middle-aged and older cats in the United States, affecting up to 10% of cats over the age of 10.\u003c\/p\u003e\n\u003ch3\u003eQ2: How does methimazole in Felimazole work to control hyperthyroidism?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e Methimazole blocks thyroid peroxidase, the enzyme that incorporates iodine into thyroglobulin to produce T3 and T4 hormones. By shutting down this step, it reduces how much thyroid hormone the body makes and brings circulating levels back into a healthy range. Peak blood levels are reached within 1 to 1.5 hours after dosing.\u003c\/p\u003e\n\u003ch3\u003eQ3: How does the 5 mg Felimazole tablet differ from the 2.5 mg tablet?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e Both strengths contain the same active ingredient and work the same way. Treatment always starts at 2.5 mg twice daily. The 5 mg tablet is used when doses need to go higher, since all adjustments are made in 2.5 mg steps. Your veterinarian will decide which strength fits your cat's T4 levels and clinical progress.\u003c\/p\u003e\n\u003ch3\u003eQ4: Why does my cat need regular blood tests while on Felimazole?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e Methimazole can cause serious effects including blood disorders and liver enzyme changes that may not show obvious symptoms early on. Checking bloodwork at 3 weeks, 6 weeks, and every 3 months after that keeps thyroid levels on track and helps catch any concerning changes before they become harder to manage.\u003c\/p\u003e\n\u003ch3\u003eQ5: Is Felimazole a permanent cure for hyperthyroidism in cats?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAns:\u003c\/strong\u003e No. Felimazole controls the condition by reducing hormone production but does not fix the underlying thyroid problem. If treatment stops, hormone levels rise again and symptoms return. Most cats stay on methimazole for life unless a definitive option like radioactive iodine or surgery is chosen.\u003c\/p\u003e\n\u003ch2\u003eClinical Research\u003c\/h2\u003e\n\u003cp\u003e\u003ca aria-label=\"Visit a webpage about Methimazole for cats: uses, dosage, and side effects | petmd\" title=\"Methimazole for cats: uses, dosage, and side effects | petmd\" href=\"https:\/\/www.petmd.com\/pet-medication\/methimazole-tapazole-felimazole\"\u003ehttps:\/\/www.petmd.com\/pet-medication\/methimazole-tapazole-felimazole\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca aria-label=\"Visit a webpage about Https:\/\/animaldrugsatfda.fda.gov\/adafda\/app\/search\/public\/document\/downloadfoi\/857\" title=\"Https:\/\/animaldrugsatfda.fda.gov\/adafda\/app\/search\/public\/document\/downloadfoi\/857\" href=\"https:\/\/animaldrugsatfda.fda.gov\/adafda\/app\/search\/public\/document\/downloadFoi\/857\"\u003ehttps:\/\/animaldrugsatfda.fda.gov\/adafda\/app\/search\/public\/document\/downloadFoi\/857\u003c\/a\u003e\u003c\/p\u003e","brand":"Dechra","offers":[{"title":"100 tablets","offer_id":41793187086497,"sku":"FEL-050","price":257.0,"currency_code":"HKD","in_stock":true},{"title":"1 tablet","offer_id":41793187119265,"sku":"FEL-050-1","price":3.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0593\/2446\/5313\/files\/felimazole-methimazole-tablets-for-feline-hyperthyroidism-5-mg-pet-473.jpg?v=1778213889","url":"https:\/\/hardypaw.com\/en-hk\/products\/dechra-felimazole-methimazole-tablets-cats-5mg","provider":"HardyPaw","version":"1.0","type":"link"}
