    Hello, can anyone advise me what the dose is for thyronorm for cats. My old cat is currently on vidalta 10 tablets, one a day. What’s the equivalent dose for thyronorm?
    Any advice appreciated :)

    What has your vet prescribed?

    It depends on the cat’s thyroid levels. You should only use medication prescribed for your cat and the vet should have the container marked with the quantity.

    Hi Torin my vet prescribed 2.5mg twice a day when she was on Vidalta 15 but I’ve just had a new packet of thyronorm and it says 1,2 ml twice a day. My cat is now on vidalta 10. We switch to the thyronorm if we go away so that it’s easier for our cat sitter to administer the medicine. I spoke to the vet nurse yesterday and they said the 1.2 ml is the correct dose but I can’t believe it is as it’s so much more than she was on before when she was taking the vidalta 15! Going away today and not sure what to tell cat sitter !!

    Thyronorm & Vidalta contain different active ingredients - Thyronorm contains Thiamazole and Vidalta Carbimazole. So the amount in mg for the two different ingredients may well be different.

    My small cat took 1.25 mg of Thyronorm twice a day, instead of 1.25mg twice a day of Felimazole, but she’s never had Vidalta, sorry.

    Felimazole contains both Methimazole and Thiamazole. The dose for a cat of a given size varies according to how much is needed to control the hyperthyroidism.
