• My cat was prescribed Felimazole, and I've administered 1/2 pill twice per day for 7 days, followed by just completing 7 days of full pill twice per day (supposed to continue until check-in blood testing Aug. 6). He threw up 5-6 times yesterday, and I'm wondering if related to medication. I gave him 1 full pill last night after he hadn't vomited for several hours, and he vomited once after an hour, but no more following. I administered 1/2 pill this morning, and wonder if that is okay? He had not vomited all night. Can I continue with 1/2 pill to see if tolerates, or will this disrupt the needed dose of medication? Should I try full pill once more to see if he was maybe just a bit ill from something unrelated? He has eaten, drank water, and used the litter box since, so he's not severely ill. Thank you!

    Hi Anna,
    I recommend that you talk to your local veterinarian who prescribed the medication about this question. The best answer to this will depend on a few different factors including your cat’s overall health, the severity of the hyperthyroidism, and the timing of the vomiting. Your vet knows your pet’s medical history and they will be better able to answer your questions about this.
