Thyronorm 5 mg/ml Oral Solution for Cats – Hyperthyroid Treatment in Liquid Form

Thyronorm 5 mg/ml Oral Solution for Cats is a liquid antithyroid medicine used to treat cats with hyperthyroidism. Hyperthyroidism is a common condition in older cats where the thyroid glands produce too much thyroid hormone, which can lead to weight loss, increased appetite, restlessness, rapid heart rate and other health problems. Thyronorm helps bring thyroid hormone levels back towards normal so your cat can feel more comfortable and stable.

This product is licensed for two main uses:

• To stabilise hyperthyroid cats before a surgical thyroidectomy

• For the long-term medical management of feline hyperthyroidism when ongoing treatment is chosen instead of surgery or radioactive iodine therapy

Thyronorm is a prescription-only medicine (POM-V), so you will need a valid veterinary prescription before we can dispense it.

What is in Thyronorm 5 mg/ml Oral Solution?

Thyronorm contains the active ingredient thiamazole (also called methimazole) at a strength of 5 mg per ml of solution. Thiamazole works by reducing the production of thyroid hormones in the thyroid gland.

The solution also includes other ingredients to help create a stable, palatable liquid, including a honey flavour to improve acceptance in many cats. Thyronorm is an off-white to light yellow opaque liquid and is supplied with a special dosing syringe designed to give very precise volumes.

Bottles are available in two sizes:

• 30 ml

• 100 ml

When might a vet prescribe Thyronorm?

Your vet may recommend Thyronorm for your cat if:

• Your cat has been diagnosed with hyperthyroidism based on examination and blood tests

• Short-term stabilisation is needed before considering surgery

• Long-term medical control is preferred or is the safest option for your cat’s overall health

Some cats are not ideal candidates for surgery or other treatments, so long-term medication with Thyronorm can be a practical way to manage hyperthyroidism over the cat’s lifetime.

How is Thyronorm given?

Thyronorm is given by mouth using the graduated dosing syringe supplied with the bottle. Your vet will calculate the starting dose for your cat and will show you exactly how to measure the prescribed amount using the syringe scale. The dose is usually divided into two daily doses so that your cat receives medicine morning and evening, but you must always follow your own vet’s instructions.

Important points about giving Thyronorm:

• Shake the bottle gently if advised by your vet or the package leaflet

• Use only the syringe supplied with the product

• Give directly into your cat’s mouth – do not mix into food unless your vet specifically tells you to, as this can affect how reliably the medicine is taken

• Try to give the doses at the same times each day and in a consistent way in relation to feeding

If you miss a dose or are unsure whether your cat has received all of the dose, contact your vet for advice on what to do next. Do not change the dose or stop treatment without speaking to your vet.

Monitoring and follow-up

Hyperthyroidism is a long-term condition and needs regular monitoring. Your vet will usually:

• Check blood tests (including thyroid hormone levels) before starting treatment

• Arrange follow-up blood tests after the first few weeks of treatment and then at regular intervals

• Adjust the Thyronorm dose if necessary, based on blood results and your cat’s clinical signs

Regular monitoring helps to ensure that:

• Thyroid hormone levels are controlled

• Your cat is not becoming hypothyroid (too little thyroid hormone)

• Any effects on kidneys, liver or blood cells are detected early

Many cats will need to stay on treatment for the rest of their lives, and your vet’s ongoing checks are an important part of keeping them comfortable and safe.

Safety and precautions

Thyronorm is a powerful prescription medicine and is not suitable for every cat. It must only be used under veterinary supervision. According to the official product information, it should not be used in:

• Cats with certain serious systemic diseases, such as primary liver disease or diabetes mellitus

• Cats with known disorders of white blood cells or platelets

• Cats with suspected autoimmune disease

• Pregnant or lactating queens

If your cat has kidney problems, heart disease or other significant health issues, your vet will carefully weigh up the risks and benefits before prescribing Thyronorm and will usually recommend closer monitoring.

Possible side effects may include digestive upset, changes in appetite, lethargy, skin or coat changes, or changes in blood test results. More serious reactions are uncommon but can include problems with blood cells or liver function. Your vet will advise you what to watch for and when to contact the practice urgently.

Use in people and handling advice

Thyronorm is a veterinary medicine but it can still affect people who handle it. The product information advises that:

• Pregnant women, women trying to conceive and people with known thyroid problems should avoid handling the product or the litter and vomit of treated cats

• Hands should be washed after administering the medicine

• Syringes and bottles should be stored out of the reach of children

If anyone in the household accidentally ingests the product or develops symptoms after exposure, medical advice should be sought and the product information leaflet shown to the doctor.

Frequently asked questions about Thyronorm

Is Thyronorm 5 mg/ml Oral Solution for Cats a prescription-only medicine?
Yes. Thyronorm is a POM-V product, which means you must have a valid veterinary prescription before we can supply it.

How long will my cat need Thyronorm?
Hyperthyroidism is usually a lifelong condition. If your vet is using Thyronorm for long-term medical management, most cats will need to stay on treatment indefinitely, with the dose adjusted over time as needed.

Can I change the dose myself if my cat seems better or worse?
No. Never change the dose or stop Thyronorm without speaking to your vet. Dose changes are based on blood test results and your cat’s clinical signs.

Can Thyronorm cure hyperthyroidism?
Thyronorm does not cure the underlying thyroid problem, but it can control the signs of hyperthyroidism by reducing thyroid hormone production. Other options, such as surgery or radioactive iodine, may be curative in some cats; your vet will discuss what is most appropriate for your individual pet.

What should I do if I spill some Thyronorm?
Wipe up spills straight away with disposable materials and wash your hands afterwards. Keep the bottle and syringe clean and dry.

What if my cat is difficult to medicate?
Thyronorm is a liquid with a flavour designed to make it easier to give than tablets for many owners, but every cat is different. If you are struggling, contact your vet team – they can demonstrate techniques or discuss other options.
