Vidalta for Cats

Vidalta for Cats - For cats with hyperthyroidism

Vidalta for Cats are tablets used to manage hyperthyroidism in cats. Vidalta contains the active ingredient carbimazole, which helps reduce the production of thyroid hormones in cats with an overactive thyroid gland. The treatment is designed for once-daily dosing and is available in 10mg Vidalta and 15mg Vidalta tablets.

Hyperthyroidism is a common condition in older cats, and Vidalta provides an effective and convenient option to support long-term hormone regulation. The tablets are modified-release, which means the active ingredient is released gradually over time, allowing for more stable blood levels of the drug and improved control of symptoms.

What Is Hyperthyroidism in Cats?

Hyperthyroidism is a medical condition that occurs when the thyroid glands in a cat's neck produce too much thyroid hormone (known as thyroxine, or T4). This hormone plays a key role in regulating the body's metabolism. When the thyroid gland becomes overactive, it speeds up the metabolism, which can lead to a variety of symptoms and health complications.

Hyperthyroidism is most often caused by a benign (non-cancerous) growth on the thyroid gland, called an adenoma. In rare cases, it may result from a malignant tumour. Hyperthyroidism is typically seen in middle-aged and older cats, most commonly over the age of ten.

Symptoms of hyperthyroidism in cats may include:

• Weight loss despite an increased appetite
• Increased thirst and urination
• Vomiting or diarrhoea
• Hyperactivity or restlessness
• Poor coat condition or hair loss
• Rapid heart rate
• High blood pressure

If left untreated, hyperthyroidism can lead to serious complications, including heart disease, kidney damage, and high blood pressure, which may impact a cat’s quality of life and longevity.
How Vidalta Works

Vidalta contains carbimazole, which is converted in the body into methimazole, the active form of the drug. Methimazole inhibits the production of thyroid hormones by blocking the enzyme thyroid peroxidase, which is necessary for the synthesis of T3 and T4 hormones.

By reducing the production of these hormones, Vidalta helps bring the cat’s metabolism back to a more normal rate. This improves symptoms and reduces the risk of complications associated with hyperthyroidism. The modified-release formulation of Vidalta ensures a gradual and consistent release of the medication over 24 hours, allowing for once-daily dosing. This is particularly helpful for owners managing long-term treatment at home.

Vidalta does not cure hyperthyroidism but provides effective symptom control. It is often used as a long-term daily medication, especially for cats that are not suitable candidates for surgery or radioactive iodine treatment.
Dosage and Administration

Vidalta is available in 10mg and 15mg tablet strengths. The dosage is determined by the prescribing veterinary surgeon based on the cat’s weight, thyroid hormone levels, and overall health status. It is essential to follow the vet’s dosing instructions precisely, as thyroid hormone levels need to remain within a healthy range.

Vidalta tablets must be given whole, not crushed or broken, and should ideally be administered at the same time each day. Vidalta should be given with a small amount of food or directly into the cat’s mouth.

Monitoring is a critical part of treatment. Regular blood tests will be required to assess the cat’s thyroid hormone levels and adjust the dosage if needed. Kidney function and blood pressure may also need to be monitored, especially in the early stages of treatment.
Precautions and Safety Information

Vidalta is a prescription-only medicine (POM-V) and should only be used under veterinary supervision. Cats receiving Vidalta must be monitored closely for any side effects or changes in behaviour or appetite.

Some cats may experience side effects, which can include:

• Vomiting
• Lethargy
• Lack of appetite
• Diarrhoea
• Anaemia (in rare cases)
• Changes in white blood cell counts

Any unusual symptoms should be reported to the prescribing vet. In rare cases, serious side effects may require discontinuation of treatment or switching to an alternative therapy.

Vidalta should not be used in pregnant or lactating cats, or in cats with pre-existing liver disease or blood disorders unless the vet considers it absolutely necessary. It is not suitable for kittens or cats under a certain weight threshold.

As with all medications, keep Vidalta tablets out of reach of children and other animals. Wash hands after handling the tablets, and avoid contact with broken or crushed tablets. Women who are pregnant or trying to conceive should avoid handling Vidalta.
