We used to use the topical methimazole often at home. Two problems: it does buildup on the ear a bit if not rubbed in fully, so that the ear becomes scaly-looking. We used to recommend using alternate ears EOD. Other problem is (as others have mentioned), it is not as stable and the efficacy of this preparation cannot be guaranteed. However, it is easy to apply and great for cats that cannot easily be pilled and where other treatments are not an option.

Hi if his heart rate and renal parameters are reasonable I'd opt for thyroidectomy every time:-)

Have you done the maths to compare costings of daily tx and bloods v's I131? The succession rate is so good and much less stress for everyone. I have found here in NZ it's not that expensive.

Our old cat who recently passed away at the tender age of 18 was hyperthyroid.

She had a thyroidectomy at the age of 12 and then went on to have 4 hyperthyroid free years before the other gland went. She had been treated medically initially but eventually was not responding so well to the medication so we opted for thyroidectomy (it helped that I worked with a vet at the time who was a dab hand at the op!). Second time round we just stuck with medical tx, she did well on 10mg vidalta for a good year but then got to the stage where 15mgs was too much and 10mg not enough. We stuck with treatment for as long as her quality of life was good.

I used to run Radioactive iodine at my old clinic if you have any questions, I may be able to help

Good luck

The other option and probably only an option in insured cases is treatment with radioactive iodine

We have used Methimazole from Summit in the past. Owner compliance failed though and we didnt see the cat after a few months. I think it worked out quite expensive for them. Otherwise i think its a good idea

Hi we have several cats on it and I think its great. you can get it very easily from Summit Pharmaceuticals www.svprx.co.uk

you get 3 x 1ml syringes and start them on 0.05ml applied to the pinna (alternate daily) once daily. You then repeat T4 after 10-14 days . so far each cat has been within normal ranges at this stage so very happy owners.

summit will deliver next day if ordered before 2pm. I also did a price comparison and its pretty much the same cost as vidalta and felimazole

how about carbimazole 5mg (yes I know Vidalta is the licensed product but the doseage is just too high for some cats and as you shouldnt be crushing or splitting Vidalta whereas you can with carbimazole). We have one cat at work that is on carbimazole 5mg as neither felimazole or vidalta suited and touchwood we are now getting somewhere near - ok its not once daily dosing as it would be with vidalta but it does seem to be suiting this cat. Another tip is do not get your carbimazole through Dunlops unless you want to pay through the nose - we get ours through Munroes(found on vetcel at a fraction of the price)

i've not used it, but have mixed feelings about it, I would not use it if you have small children who might rub it off or if your other cat grooms the one you are applying it to as I have heard issues where owners who didn't wear gloves became hypothyroid and one of our nurses decided against using it because she has a little one who might rub it off. Oh and our medics aren't that convinced about its efficacy.

you don't need a special treatment cert for it any more as summit pharmaceuticals now produce and sell it in the UK, they are great and relatively quick at sending it out

I've not heard about any new meds but can ask around and see if there is any rumours at work!
