Medication
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.
Most Liked Negative Review
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

Only form of Felimazole I can easily get my cat to take!
From UndisclosedComments about Felimazole (methimazole)My cat loves Dechra Felimazole! Amazing, right? I have used another tablet form of Felimazole and I had the most ridiculous times getting him to take his thyroid medication. This cat does NOT like taking any medication previously, no matter the form, be it liquid, powder, capsule or tablet. No matter what flavor, treat or food I use to get medication in him when needed. And he needs to take Felimazole twice daily! At first, I was molding his favorite soft treat around the tablet to get him to take it. At times, the tablet would fall out of the treat. I thought I'd have to re-treat or something to get him to take it. But, No! He still goes for the tablet without the treat! He has needed to be on the medication for a bit over a year now and I don't need to do anything special to get him to take it! I just put it in his bowl and he does the rest easily! No side effects from the medication itself, either. Also, I really appreciate the tablet being a hot pink color. I've dropped the tablets on the floor more than once and thankfully have been able to find it immediately every time! Additionally, thank you VetRxDirect staff for always being very friendly and efficient. We appreciate your assistance! Sincerely, Kim and Stryder -
I am very happy with the product and customer service
From UndisclosedComments about Felimazole (methimazole)As I said for another medication that I ordered, my cat has medical issues that require that he take medication for the rest of his life. I found the exact mediation at VetRxDirect at a substantial savings. I am very happy with both products, the people at VetRxDirect and will definitely continue to use them. -
Convenient and tidy
From UndisclosedComments about Felimazole (methimazole)This smaller dosage helps me avoid the mess and inaccurate half-pill dosing. They are small enough to go down easily but large enough to fit in my "cat piller." Pink coating makes them easier for the cat to swallow and easier for me to find if I drop one. So far, the medicine is doing what it's supposed to. I have no reason to doubt the quality. -
I will always buy this from you.
From UndisclosedComments about Felimazole (methimazole)My vet has told me that our 11 year old sweet girl has to take this throid medication twice a day for the rest of her life. VetRx staff helped me secure the prescription for her. Great caring service. -
My cat has to use this medication forever
From UndisclosedComments about Felimazole (methimazole)My 11years old cat was diagnosed with hyperthyroidism. She was prescribed this medication, one pill, once a day. -
Coated pills are great!
From NevadaComments about Felimazole (methimazole)I wish I had known about these coated pills much sooner! They are so much easier to administer. I don't even need to squirt in water with a syringe to get my cat to swallow this pill. He takes 2.5 mg twice per day. He swallows it then gets sweet potato baby food mixed with water as a treat. This helps so that he associates the pill with something positive. -

Does the coating on Felimazole cover up the very bitter taste and probably offensive smell? What function does a coating accomplish??
-
Felimazole has a sugar coated formulation to improve palliability of methimazole. It does help cover up the bitter taste if swallowed immediately, and the tablets do not possess an offensive smell. The manufacturer states that the tablet should not be crushed or broken. Pregnant women, women who may become pregnant, and nursing mothers should wear gloves when handling tablets, litter or bodily fluids of cats treated with Felimazole.
