Benazepril is rated 4.333333333333333 out of 5 by 3.
Rated 3 out of 5 by from Too big I got these pills initially from the vet, and i could tell my dog didn't really like them cause i had to hide them deep in her treats for her to take them. I ordered from here and the pills are so big, its hard to hide the taste and she keeps spitting them out. Takes me like 10 min everyday to get her to eat it, kind of a hassle.

Do you accept Canadian Vets prescriptions?

Asked by: Mrputterer
Yes they do but you will lose your vet -- their customer service is awful. My vet had to send them their requirements FOUR times and they did not even acknowledge they finally got it.

my vet sometimes gets very tiny pills which i have to cut in half for my cat. can i purchase pills that are approx 3/8 inch

my vet gets benazepril 5mg for my cat which are normally about 3/8 inch but her distributor is now giving her very tiny pills about 1/4 inch which i have to cut in half. its hard to administer and confirm if the cat has swallowed the pill or is gumming it to spit out later. if you sell the pill of larger size 3/8 then i would be interested in throwing these pills in the trash and purchasing 30 pills to be cut in half. thanks sam

If the normal dose for Benazepril, why are there only 5 mg tablets? Should I cut them?

My dog is 6 years old, Schipperke
Asked by: Pirate
The dose for Benazepril is based on weight of your pet. The dose range for benazepril is 0.1-0.2 mg/lb 1-2 times a day. The lowest strength of benazepril available for this medication is 5mg. You may cut the tablets with a pill cutter if is necessary to achieve the dosage recommended by your pet's veterinarian,

i just got new refill on my Benazepril 5 mg but are much larger than the old ones. Is this normal to be different size or possibly wong MG ??

Asked by: Zoe
Any time you get a drug you don't recognize as normal, it is always best to verify that it is the correct drug/dose. Most of the time, it is different because it is produced from a different manufacturer. Most pharmacies often receive different generic drugs due to pricing. The easiest way to identify the drug is to do a google search for "pill identifier". Pill identifier websites allow you to put the imprint, shape, and color of the pill and it will identify the pill for you. Hope this helps.

stopping Benazepril

Can I stop this medication, Benazepril, after giving it to my dog for 2 years? All informatiom I read states "do not stop this medication". The cardiologist says to stop it 'cold turkey', I am getting conflicting answers and am considering reducing this med over a period, rather then what was told to me of stopping all at once. The dog has a mumur, slightly enlarged heart.
Asked by: bp
It is best to taper the dog off of this drug. If you stop 'cold turkey', his blood pressure will jump and take some time to come back down. By tapering, you are giving his body a chance to slowly adjust to the absence of the drug.
