Felimazole 5mg/ml Oral Solution for Cats 30ml

Feline hyperthyroidism is a common hormonal disorder in older cats, caused by an overactive thyroid gland producing too much thyroid hormone. This can lead to various symptoms like weight loss despite increased appetite, hyperactivity, excessive thirst, and poor coat condition. Felimazole 5mg/ml Oral Solution for Cats 30ml is a trusted veterinary prescription medicine designed to manage this condition effectively.

How Felimazole Works

The active ingredient in Felimazole 5mg/ml Oral Solution for Cats 30ml is Thiamazole, an antithyroid agent. It works by inhibiting the production of thyroid hormones in your cat's body, helping to bring their hormone levels back into a healthy range. This can significantly improve their quality of life and alleviate the uncomfortable symptoms associated with hyperthyroidism.

Felimazole 5mg/ml Oral Solution for Cats 30ml is used both for the stabilisation of hyperthyroidism before surgical removal of the thyroid gland (thyroidectomy) and as a long-term treatment for cats where surgery is not an option or desired. Administering this oral solution is straightforward, making it easier for pet owners to manage their cat's ongoing care.

Always follow your veterinary surgeon's specific instructions for administering Felimazole 5mg/ml Oral Solution for Cats 30ml. The information below is a general guide from the patient information leaflet.

• Administration: Felimazole 5mg/ml Oral Solution is for oral use only.
• Starting Dose: The recommended starting dose is 5 mg per day (which is 1 ml of the veterinary medicinal product).
• Dosing Frequency: Wherever possible, the total daily dose should be divided into two equal doses and administered morning and evening. If once-daily dosing is preferred for compliance, this is acceptable, though twice-daily may be more effective in the short term.
• Accurate Dosing: Use the syringe provided in the package to administer the dose accurately. The syringe fits onto the bottle and is graduated in 0.25 mg increments up to 5 mg.
• Method of Administration: Withdraw the required dose and administer the solution directly into your cat's mouth.
• Monitoring: Blood tests (haematology, biochemistry, and serum total T4) should be assessed before starting treatment and after 3, 6, 10, and 20 weeks, and then every 3 months thereafter. Dose adjustments will be made by your vet based on these results.
• Dose Adjustments: Adjustments should be made in increments of 2.5 mg (0.5 ml) or, for particularly small adjustments, 1.25 mg (0.25 ml). The aim is to achieve the lowest possible effective dose.
• Maximum Dose: The dose administered should not exceed 20 mg per day (4 ml of the veterinary medicinal product).
• Long-Term Treatment: For long-term management of hyperthyroidism, the animal should be treated for life.

Please read the following warnings carefully before administering Felimazole 5mg/ml Oral Solution for Cats 30ml. Consult your veterinary surgeon if you have any concerns.

Contraindications: Do not use if your cat is suffering from:

• Systemic diseases such as primary liver disease or diabetes mellitus.
• Signs of autoimmune disease.
• Disorders of white blood cells (e.g., neutropenia, lymphopenia).
• Platelet disorders or coagulopathies (especially thrombocytopenia).
• Do not use in pregnant or lactating females.
• Do not use if your cat has a known hypersensitivity to Thiamazole or any of the excipients.

Special Precautions for Use in Target Species:

• If more than 10 mg per day (2 ml of the veterinary medicinal product) is required, animals should be monitored particularly carefully.
• For cats with renal dysfunction, use should be subject to careful risk-benefit assessment by the clinician. Renal function should be monitored closely.
• Haematology (blood count) must be monitored due to the risk of leucopenia or haemolytic anaemia.
• If your cat suddenly appears unwell during therapy, especially if febrile, a blood sample should be taken for routine haematology and biochemistry.
• Neutropenic animals (neutrophil counts <2.5 x 10⁹/litre) should be treated with prophylactic bactericidal antibacterial drugs and supportive therapy.
• As Thiamazole can cause haemoconcentration, cats should always have access to drinking water.

Adverse Events:

Adverse reactions have been reported, particularly with long-term use. Many signs are mild and temporary and do not usually require withdrawal. More serious effects are generally reversible upon stopping medication.

• Uncommon (1 to 10 animals / 1,000 treated): Vomiting, anorexia, inappetence, lethargy, pruritus, excoriation, prolonged bleeding, icterus, hepatopathy, eosinophilia, lymphocytosis, neutropenia, lymphopenia, leucopenia (slight), agranulocytosis, thrombocytopenia, haemolytic anaemia.
• Rare (1 to 10 animals / 10,000 treated): Autoimmune disorder (serum anti-nuclear antibodies).
• Very rare (<1 animal / 10,000 treated): Lymphadenopathy, anaemia.

If overdosage occurs, stop treatment and provide symptomatic and supportive care. Signs of overdose can include anorexia, vomiting, lethargy, pruritus, and various haematological and biochemical abnormalities.

Interactions with Other Medicinal Products:

• Concurrent treatment with phenobarbital may reduce the clinical efficacy of Thiamazole.
