Felimazole (methimazole) Coated Tablets for Cats

If your cat has an overactive thyroid gland, your veterinarian may prescribe FDA-veterinary approved Felimazole to help stabilize your cat’s condition. While Felimazole can’t stop the condition, it will help your cat feel better and improve her quality of life

  • Manages symptoms of hyperthyroidism in cats
  • FDA approved
  • Small, coated tablets for easy dosing

Hyperthyroidism, or overactive thyroid, in cats causes weight loss, increased appetite, excessive thirst, hair loss, and more. While there is no permanent treatment for hyperthyroidism, your veterinarian can help your cat feel better by regulating the thyroid with prescription Felimazole. The active ingredient in each small, coated pill is methimazole, which reduces the amount of the thyroid hormone your cat’s thyroid gland produces.  The result is a healthier cat and a better quality of life.

  • Q:

    Currently my female cat takes 5mg Methemazole chewable 1/2 2x daily; individuallly blister packed. i like to order tabs should I order 2.5mg or 5mg and cut the pill in half??? Please advise. 
    Asked on 1/22/2015 by Poes poes from New York, NY, United States

    1 answer

    • A:

      Felimazole is a veterinary approved, non-chewable, coated tablet containing methimazole. The manufacturer warns not to crush or break the tablets and to wash hands with soap and water after administration to avoid exposure to drug. They also recommend to wear gloves to handle moistened or broken tablets. Splitting the coated tablets will expose the owner to the thyroid hormone reducing effects of the drug. Since methimazole is potentially a lifetime medication for cats suffering from hyperthyroidism, owners need to be aware that repeated handling of split, broken or moistened Felimazole tablets will increase the risk of decreased thyroid levels. If your cat’s dose is 2.5mg, we would recommend to order the Felimazole 2.5mg tablets.

    • A:

      Laurie,

      Adverse events attributed to methimazole commonly occur within the first few months of therapy and include vomiting, lack of appetite, and depression/lethargy as seen most often.  Gastrointestinal effects occur in about 10% of cats treated with methimazole.  If vomiting continues to be a problem, speak with your veterinarian on possible adjustments for your cat to better tolerate methimazole.

      Thank you,

  • Q:

    If the pill is put in the cat"s food (she is not fooled by the pill pockets, is the medication rendered ineffective if is dissolves in the food?
    Asked on 10/6/2013 by Bertrice

    1 answer

    • A:

      Bertrice,

      There would be no way to determine the shelf-life or stability of the active ingredient, methimazole, if it were to be placed in your animal's food.  Methimazole is a bitter drug and if the tablet was crushed and placed in your cat's food she may not eat all of it.  The amount of medication taken would then be difficult to determine.  Please share your troubles pilling your cat with your cat's veterinarian.  The veterinarian may be able to help you with techniques on pilling your cat or other administration options for methimazole.

      Thank you,

  • Q:

    Can you halve a felimazole tablet or does it just break into a bunch of pieces and if you do halve it, will it be less effective?
    Asked on 10/1/2013 by Terri

    1 answer

    • A:

      Terri,

      Felimazole can be halved and breaks cleanly, however the coating on the tablet is covering a bitter taste, and cats may be less likely to take the pill because of the taste.  There is also the concern of being exposed to the medication, so, as with any medication, proper precautions should be taken when handling the tablets.  The medication is not less effective when split, as long as it is split evenly.

      Thank you,

      Liz,

      Felimazole tablet pictures can now be found under the 'Description' tab above. Each tablet is 5mm in diameter.

      Felimazole tablets are sugar coated to mask the taste of methimazole.

      Thank you,

    Comments about Dechra Felimazole (methimazole):

    Our vet diagnosed our almost 11 year old Siamese cat with hyperthyroidism. It has kept her thyroid level where it is supposed to be. It is a tiny pill, and very easy to give. She has to have it twice a day. A simple fix for a health problem that could have become very serious without this treatment. Also, the price at VetRxDirect is far lower than that at our vet hospital. I also received free shipping, another big plus!

    Comments about Dechra Felimazole (methimazole):

    my cat has been on this medication for awhile, but i just found vetrxdirect and their prices are much better than my vet's. they did their best to get my vet to respond with the prescription without much luck, so i did have to step in. this caused a longer delay than i had hoped for (thus the 4 star rating instead - perhaps knowing when the request was first sent would have helped).

    Comments about Dechra Felimazole (methimazole):

    This medication is easier to give than the generic I got from my vet. It comes in the size my cat takes, so I don't have to cut pills. It is coated, so it doesn't dissolve if she doesn't get it down on the first try. Since it's round and doesn't stick, she takes it on the first try most of the time. The price was less than half of what my vet charged! Since my vet put the fax from VetRxDirect in their circular file, my order was going to arrive after my current supply was gone. I sent an email and got next-day shipping, so the kitty was back on schedule. Even then the price was less!

    Comments about Dechra Felimazole (methimazole):

    I placed my first order a few weeks ago at the suggestion of my vet. My cat will now need to have this medication for the rest of her life and my vet suggested I might be able to be able to purchase it more economically on the internet. I did so and was very pleased with the service and products received. Thank you and I look forward to placing additional orders in the future.

    My 14 year old cat has been on Felimazole for about 2 years, 1 tablet per day, and her bloodwork is consistently excellent. You'd never know she has thyroid disease. Thank you to VetRxDirect for making this affordable! Every day with my best buddy is precious.
