Hi everyone,
A few weeks ago, Bailey was diagnosed with hyperthyroidism. On October 22nd, we started giving her Tapazole 5mg, 2x/day. I was only giving her Tapazole as a trial to make sure she would be a good candidate for radioiodine treatment. She seemed to be tolerating the Tapazole fairly well. She had been scratching at her face a bit which caused some abnormal skin irritation, which I'm guessing was in response to the Tapazole, but it was not severe. However, 2 days ago (after taking the Tapazole for 2 weeks) she began vomiting regularly and could not keep ANYTHING down. I discontinued the medication and picked up her food and water at the advice of her vet and monitored her to see if she was improving at all, which she did not. I brought her to the emergency vet early yesterday morning, they gave her SubQ fluids and an anti-nausea injection, and I brought her back home where she seemed to be improving. She went downhill again, so I brought her back last night, and she's still there today on IV fluids and anti-nausea medication. She did get x-rays to rule out foreign body ingestion, and also a full blood panel (liver, kidneys, CBC, etc.) with no abnormal results. She had a fever of 103.7 last night, which was weird since she did not have a fever when I brought her in yesterday morning. Her fever has since gone down and they finally were able to get her to eat this morning.
The thing is, the vets seem to be on the fence about whether or not this was caused by a reaction to the Tapazole since she was on it for 2 weeks before this happened with no major problems. I can't imagine what else it could be, since she is an indoor cat and an only cat, and my boyfriend and I don't have any contact with other cats. The x-rays did not reveal any foreign body, and she has no access to anything that could be poisonous. I know that vomiting can be a side effect of Tapazole, but that fact that she was on it for 2 weeks before this happened is making everyone wonder.
Has anyone else dealt with their cat having a negative reaction to Tapazole? If so, did it happen soon after the medication was started? Is it normal for a serious reaction to take 2 weeks to manifest?
Thank you for reading, and thank you in advance for any advice you may have!
