Hyperthyroid meds... how much is too much?

[jennielynn1970]

My mom called me to tell me their one cat, Lucey, is now on thyroid medication (methamizole I think it is called). The vet has Lu on 5mg twice a day.

Isn't that a high dose?? I know I gave the same meds to my one FIV guy, and his thyroid was not controlled when he first came to me, and he was on 5mg. once a day (1/2 AM, 1/2 PM).

A woman in another rescue that I was fostering for said that it is almost a lethal dose for a cat. :eek:

Any thoughts on this??

I wonder if she meant 5 mg 'broken in half' and given twice a day, like your FIV kitty?

You might want to double check on that...that might have been what the vet said, and maybe something got misunderstood. :)

Nope... it's on the bottle.

That dose is okay. Google tapazole for cats and you'll see that they can have 5mg even BID (twice a day).
