Hi, I am new to this site and I don't know when you made your original post, but as I was searching for information on hyperthyroidism as well, I cam across you post. I have attached an excerpt from a website "http://www.allfelinehospital.com/pet-library.pml". Apparently, some cats can get itchy faces using this medicine:
Facial itching is a more serious side effect. This side effect also resolves with anti-itch medication and discontinuing methimazole. Cats who have this side effect can be expected to have it again if medication is restarted, so another form of treatment should be used. Facial itching occurs in less than 4% of cats on methimazole.
Don't know if it helps, but you might want to check their site. They have a detailed report on hyperthyroidism. Good luck.
