Hi,
My cat (age 8-10ish) was recently diagnosed with hyperthyroidism after losing 3lbs in one year (not really other symptoms). I was told a normal T4 range is 10-60, and hers was 184. I started her on felimazole (2.5mg twice daily), and am now at the 3-week mark. The follow-up blood test shows her T4 is now 38, so back to normal as long as I keep the dosage up. However I am dealing with side effects!
First of all, the vomiting - started about 5 days ago she has puked 1-3 times every day. It happens at random times and isn't associated with feeding or pilling times, although seems more common in the early morning. She'll do the classic cat pre-puke yowl, heave and puke out some yellow-ish liquid and the occasional hairball if she has one.
Second of all, she has always had some allergic sensitivities which I have never been able to narrow down to a specific source, but she started itching her head a bit raw, between her eyes and ears. She has a history of this pre-HT and its possible its the current dry food I started feeding her not too long ago, which has chicken & rice, so I am going to switch over to grain-free, as well as swapping out the 'seafood supper' fancy feast for a slightly higher quality variety and upping the wet:dry food ratio to get more moisture in her. I had to cone her to get it to heal which always makes her very lethargic, so she's in a bit of a funk right now.
Has anyone dealt with this before (I am assuming yes)? Specifically the vomiting, does it go away after awhile? It only started after 2 weeks and is now a more-than-daily occurrence. I'm aware of the radiation treatment, but it is not super available in my area and sure to be extremely expensive. I will look into it more but I am ok with medicating long-term as long as the side-effects clear up.
