Very pleased with Allivet. Wish all my critters 'scripts were available through them! Even with shipping costs, this one is more reasonable than going to the vet office to get it filled!

It has worked well for my senior cats for years. The coating makes it easier for them to swallow. The non coated variety is bitter and difficult to give if they get a taste of the medication.

Allivet, my favorite pet pharmacy . You know why - I am ordering from them for a while, cat has hyperthyroid, and needs everyday medication twice a day... otherwise - all pleasures of hyperthyroid in felines, you name it.... My vet did not fill prescription on time, there was a week of glitches, and then I called with two days of pills supplies - AlliVet not only followed up with Vet but also provided me next day shipping free of charge as a courtesy, and all this happened after their shipping department was already closed for the day. How cordial and professional are these people! Thanks a lot for your help, and I will continue using your services in future. Wish you all the best, dear AlliVet! Lanna

If you are halving tablets please purchase the 2.5 mg. Our cat was able to have normal levels after making the switch to the 2.5 mg as opposed to halving a 5mg tablet.

I crush these tablets and sprinkle over wet cat food. My picky cat doesn't mind it at all! I tried using generic and the flavor must be different because cat would not touch it... but this one is different and a lifesaver - keeps me from having to pill a cat with 2 tabs twice a day!

Felimazole consistently keeps my pets Thyroid level in the therapeutic range, but it doesn't cause the skin irritation that traditional pharmacy methamazole does. And, the price here is fantastic!

Felimazole is easily administered to my older cat and works well to keep her T4 in check. The protective coating makes it much safer to handle.

These meds seem to be working in that my 14 year old cat is more energetic and no longer uncomfortable. Also he looks forward to his meds. I coat with a tiny bit of fresh ground peanut butter (no sugar or oil or anything added).

Suzan S Verified Purchase
January 22, 2016

These tiny pills are coated, so they go down better than tablets. I give my cat some canned food after the pill, and that helps it travel to the stomach quicker.

Shelley L Verified Purchase

Fast, easy and way cheaper than going to my vet for the medication.

Joyce B Verified Purchase
January 15, 2016

When my vet told me I had to start my cat on methimazole, I panic'd as I knew he would not let me get any pills down him. These coated tablets are the best! The are tiny enough to hide in a bit of soft food and because they are coated, he doesn't smell them in there. I don't have to struggle pushing a pill down his throat; he easily swallows them with food. Can't thank you enough for making a great product!

Christopher S Verified Purchase

We used to buy Felimazole tablets from our vet. After finding out about Allivet and seeing how much money we would save on our cat's meds, there was no going back. Sylvester now gets a 3-month supply without breaking the bank, and it arrives in good time.

Debra B Verified Purchase

I like ordering my cat's maintenance medication for hyperthyroidism, felimazole, because I can get a 3-month supply and the communication with my veterinarian is handled by Allivet. Shipping is quick, too.

Nola D Verified Purchase

My cat was recently diagnosed with hyperthyroidism. My last refill at the Vet's office was refilled with an uncoated tablet that I needed to split. It would splinter and was horrid to pill her --- it, having been split and splintered, might have made her refuse her medication due to the bad taste. I was forced to mix it with laxatone. Thank God I now have those little pink pills!

Stephanie B Verified Purchase
May 12, 2015

My cat's thyroid levels were at 9 although she exhibited no symptoms. Since I started giving her Felimazole, she has been at 2, and that is just after one month. She takes these twice a day and I crush them up with a pestle & mortar, then use 1 cc of water in a syringe-type dropper since she no longer is tricked by Pill Pockets! Good luck to you & your kitty!

I purchased these meds for my beloved cat Max who has hyperthyroidism for half the price my vet charged...what a savings! And, it was shipped so quickly which alleviated getting some 'hold over' meds from the vet. I highly recommend Allivet for all your pet needs - they give great customer service and make sure your vet approves your prescription very quickly.

Rebecca F Verified Purchase

My elderly cat takes this daily and Allivet's prices are always low compared to other online pharmacies. I have never had a problem with an order with them.

The size of this pill is so small that my cat does not even know he gets the pill :) great product

Jody E Verified Purchase

It does the job. My cat's thyroid numbers are perfect (he has hyperthyroidism, but this manages it). Just remember to wash your hands if you have to handle these pills, as they are powerful hormones.

Paul S Verified Purchase
October 20, 2014

This is the first time we've used Allivet and we'll definitely be back for refills. They took care of calling our vet to get the Rx approved and promptly shipped the product. Best of all, we saved over 60% what were paying in the past for the same Rx.
