My cat, Critter, is doing well on the 2.5mg Felimazole for her hyperthyrodism. I am happy with VetRxdirect and have been impressed with the staff there.

Stupid shaped pill
In 2 weeks we have worn through a pill cutter because of the super thick hard coating on the pills. They are also round not flat so portioning them is a nightmare.
If your pet needs a partial dose do not order these, get the generic and save yourself the headaches. These pills are really poorly designed, wish I could exchange them

Felimazole is saving my cat
From UndisclosedComments about Felimazole (methimazole) 2.5mg, 100 Coated TabletsA cat wondered onto our porch on an extremely hot day in Arizona. He was in pretty bad shape, but we took him to the vet. We have nursed him back to health! He does require a few medication and Felimazole is one of them and is very important for his continued health. VetRxDirect made ordering and delivering easy and it's much appreciated.-

From UndisclosedComments about Felimazole (methimazole) 5mg, 100 Coated TabletsThese pills are very easy to cut in half. 2.5 mgs are almost impossible to come by. My cat tolerates the meds and is responding beautifully.-

AIDS our Boy with his Hyperthyroidism
From UndisclosedComments about Felimazole (methimazole) 2.5mg, 100 Coated TabletsHave been using this product for approximately 3 years now for Hypothyroidism and seems to work well at controlling his condition. Now that he is older we have to melt his pill in warm water and mix into ball with his Churu sticks and that does the trick.-

Q & A

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??
-
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, VetRxDirect

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??
-
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, VetRxDirect

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, VetRxDirect
