Hello. I’m new here but I’ve learned a lot lurking on this site over the years! I finally registered because my cat Ed (age 12) was recently diagnosed with hyperthyroidism. I’d suspected it, as he had all of the symptoms, then his blood work came back with a total T4 of 4.8.
We ordered methimazole compounded into chewable treats, 2.5mg each. Started him out on 2.5 once/day for a week, he seemed ok with that, then upped to twice/day for a total of 5mg. After five days on 5mg, he went what I assume was hyPOthyroid. Lost his appetite, spent a whole day vomiting the contents of his stomach, and was lethargic. We stopped the methimazole (I keep wanting to shorten it as “meth,” but that’s not right! Heh) for several days, he received fluids and an injection of Cerenia, and recovered.
After discussing with the vet and reading several threads here, we started him back at 2.5mg total per day, cutting his treats into two 1.25mg portions. After a week of that, he’s having appetite problems again! This time, no vomiting or lethargy. It’s more like being extremely picky, and I have to pull out all the tricks to get him to finish a meal. I don’t know what to do at this point. He needs to eat and get weight back on. I don’t know if I can cut his dose down any further and have it be effective. I don’t know if ANY of the dosing he’s taken so far has been effective, because I haven’t been able to keep him on the meds long enough to get a blood draw.
My long term goal is to stabilize him enough so that he can receive the I-131 treatment.
Any advice?
