Thiafeline 1 Tablet 5mg

Thiafeline 5 mg Film-coated Tablets for Cats contain the active substance Thiamazole, an antithyroid preparation specifically formulated for felines. It is commonly used for the stabilisation of feline hyperthyroidism prior to surgical thyroidectomy, or for the long-term management of this condition, helping to regulate thyroid hormone production in your beloved companion.

Understanding Feline Hyperthyroidism

Feline hyperthyroidism is a common hormonal disorder in older cats, where the thyroid gland produces too much thyroid hormone. Symptoms can include weight loss despite an increased appetite, hyperactivity, excessive thirst, and poor coat condition. Thiafeline 5 mg Film-coated Tablets for Cats work by blocking the biosynthesis of these hormones, helping to bring your cat's thyroid levels back into a healthy range.

Amounts to be administered and administration route

• For oral use.
• For the stabilisation of feline hyperthyroidism prior to surgical thyroidectomy and for the long-term treatment of feline hyperthyroidism, the recommended starting dose is 5 mg per day.
• Wherever possible, the total daily dose should be divided into two and administered morning and evening.
• Tablets should not be split.
• If, for reasons of compliance, once daily dosing with a 5 mg tablet is preferable, then this is acceptable although the 2.5 mg tablet given twice daily may be more efficacious in the short term. The 5 mg tablet is also suitable for cats requiring higher dose rates.
• Haematology, biochemistry and serum total T4 should be assessed before initiating treatment and after 3 weeks, 6 weeks, 10 weeks, 20 weeks, and thereafter every 3 months. At each of the recommended monitoring intervals, the dose should be titrated to effect according to the total T4 and to clinical response to treatment. Dose adjustments should be made in increments of 2.5 mg and the aim should be to achieve the lowest possible dose rate.
• If more than 10 mg per day is required animals should be monitored particularly carefully.
• The dose administered should not exceed 20 mg/day.
• For long term treatment of hyperthyroidism the animal should be treated for life.

Contraindications

• Do not use Thiafeline 5 mg Film-coated Tablets for Cats in cats suffering from systemic disease such as primary liver disease or diabetes mellitus.
• Do not use in cats showing signs of autoimmune disease.
• Do not use in animals with disorders of white blood cells, such as neutropenia and lymphopenia.
• Do not use in animals with platelet disorders and coagulopathies (particularly thrombocytopenia).
• Do not use in pregnant or lactating females.
• Do not use in cases of hypersensitivity to thiamazole or to any of the excipients.

Special precautions for use in animals

• As thiamazole can cause haemoconcentration, cats should always have access to drinking water.
• If more than 10 mg per day is required, animals should be monitored particularly carefully.
• Use of the product in cats with renal dysfunction should be subject to careful risk:benefit assessment by the clinician. Due to the effect thiamazole can have on reducing the glomerular filtration rate, the effect of therapy on renal function should be monitored closely as deterioration of an underlying condition may occur.
• Haematology must be monitored due to risk of leucopenia or haemolytic anaemia.
• Any animal that suddenly appears unwell during therapy, particularly if they are febrile, should have a blood sample taken for routine haematology and biochemistry.
• Neutropenic animals (neutrophil counts <2.5 x 10⁹/l) should be treated with prophylactic bactericidal antibacterial drugs and supportive therapy.
