Rated 5 out of 5by so far so goodmy angel girl has done well on this med for the past year and a half, although sometimes goes through a weird period of vomiting and soiling in inappropriate places...not sure why. Service at Pet care was great. fast and professional 09/14/2012
Rated 5 out of 5by Local Vet Much CheaperThis RX saved my cat's life! Unfortunately, I can get it much cheaper at my local vet clinic....60 cents a 10 mg pill 05/03/2011
Rated 5 out of 5by Cat and cost effective!When I first found out Buddy had thyroid problems, I was devestated. He was on this medicine for about a year and didn't seem to improve, but it was not this medication. Turned out he has CRF and between this medication and his 3x a week fluid treatment, my cat has outlived all his nine lives and then some! PetCareRx has been nothing short of a lifesaver for Buddy and his momma. The cost is the best I have seen on the internet or locally. Thanks for everything PetCareRx! 08/09/2008
Rated 5 out of 5by Great Customer ServiceAfter finding out the devastating news about my 17 yr old cat, Macy's overactive thyroid, it was a blessing to find the Methimazole at a fraction of the cost of my vets. He charges $60 for a month's supply. I saved over $20 through PetCareRx and it's autoshipped too! The meds arrived quickly and the customer service was wonderful. I highly recommend this company for pet care needs. They deliver!!! As for Macy, she's responding well to the medication. She's eating more although not gaining weight. She's meowing again and seems more alert. Her vomiting is almost eliminated too! 06/07/2008
Rated 1 out of 5by Was a nightmare for my catMy cat proved to be highly allergic to this product. She was vomiting every day, not eating her food anymore, not drinking, and her skin was bright red. She felt so sick that she hid in the darkest places, and I thought I will lose her. I will never use this awful stuff again!!! Same thing with Tapazole, they are both the same. 05/26/2008
Rated 5 out of 5by Effective Generic with fast deliveryAfter purchasing this drug through my vet as a non-generic, I switched to this one. It has been just as effective at a much lower price. The deliveries have been fast with no problems. 04/21/2008

Rated 5 out of 5by great medicine for my older catafter just a week of being on this medicine, i noticed a difference in my cat. she became more active and she seemed to catch a "second wind" of sorts. the vet did explain that she will have to be on it for the rest of her life but she seems so much happier now. 09/21/2007
Rated 5 out of 5by Great PricePet RX offers this med for half the price of my vet. 05/25/2007
Rated 5 out of 5by 'Ozzy's' Miracle!Ozzy' is my wonderful 21 year old cat, and has been on methimazole for over a year. He had been getting very thin, and his e1 were sunken and he just looked like he was on 'death's door'. My vet recommended that we try him on 5mg a day, and within 10 days he began to look like the 'Ozzy' of old. Over the past year he's gained weight (still on the thin side, but healthy now), and is as playful as he's always been. We highly recommend methimazole. Thank you Dr. Kilgore!!! 05/25/2007
Rated 4 out of 5by Drastically improved cat's behaviorI adopted a 14 year old cat, and for the entire first month he threw up 2-3 times a day, and kept losing weight. When he was put on methimazole, he didnt throw up as often, and acted how i would expect a cat his age act, calm and nice. It didn't help my cat gain weight-- he's still very skinny though he eats a lot, but if helped him not throw up every day and i'm thankful for that!*This is a prescription item 03/08/2006
Rated 4 out of 5by Helped 9 year cat act his ageOnce my cat was diagnosed with over-active thyroid he was put on this medication twice a day and within a week (or less) we started noticing a difference. He would throw-up every day and ate a lot more and didn't sleep thru the night and kept losing weight. Now he only coughs up the occasional hairball and sleeps through the night and I have been able to reduce his food intake and he actually gained over a pound - he was too thin. He's still active and playful but more relaxed.*This is a prescription item 10/17/2005
