Is it safe to pre-prepare cat methimazole doses using butter?

Updated On September 23rd, 2025

I put my cat's methimazole in a pat of butter so he will take the meds. Can I put together more than one dose this way?

I think I know what you're asking - you're asking if you can put together multiple doses of methimazole in separate aliquots of butter, correct? According to Plumb's veterinary handbook, methimazole is supposed to be stored in a closed container, away from light and at room temperature. So I think it would probably not be a good idea to prepare your butter + methimazole "doses" ahead of time, since the butter would need to stay in the refrigerator to stay solid. If it's hard to medicate your cat, you might investigate having your vet order a compounded flavored oral suspension of methimazole. This is usually quite easy to give, and compounding pharmacies can make meds with virtually any flavor added, so pets will take them.

    I'm not sure i understand your question, if your cat needs one dose of methimazole then you only need to give him one. if it's easier with the butter you can give it to him this way on a regular basis.
