    Fast and accurate!

    By PearlsMom on Apr 27, 2021

    I was very pleased with this order. I had to mail in the prescription and pleasantly surprised how quickly and accurately the order was fulfilled. My greyhound, Pearl, needs this medication for seizures and the speed and accuracy with which the script was filled ensures she won't go without. She handles this drug well and I am very pleased. Thank you, Chewy, for the excellent service

    I started to give this to my Husky Mix to prevent her seizures. It has kept her seizures at bay but she has become very melancholy and not hungry. This is a change from the Phenobarbital which made her super hungry. I need to find out from vet if this is normal.

    controls seizures

    By Jess on Jul 24, 2020

    Our lab was only 1.5 years old when he started having seizures, and we were reluctant to give him phenobarbital because of the terrible side effects so we started with Keppra and it has been a life saver. He went 5 months without a seizure on the 500mg tablets (with the help of CBD oil) and then when he had 3 one month apart we upped him to the 750mg tablets and we’re almost at 8 weeks and counting! No side effects at all and well tolerated. I’m so thankful that chewy has it for so much cheaper than the neurologist!

    Works, but often out of stock

    By DinoDog on Jun 2, 2020

    This is the only drug we have found so far to control grand mal seizures in our Coonhound mix. Four stars because it goes out of stock a lot. Chewey is the one retailer that has had it fairly consistently. It can get really expensive depending on where you get it, but Chewey is very reasonable.

    Help greatly!

    By Annie on Feb 15, 2020

    My Buddy had a brain tumor which was causing severe seizures. This medication gave him great relief. We lost Buddy a year and a half after his diagnosis. But he had a fairly normal and happy life using levetiracetam.

    Way too expensive

    By Epipupmom on Dec 18, 2019

    The first time I got these they were $62, I figured the extra $6 was worth having them shipped to my house and not dealing with walmart. Well a month later I see a charge for $92 from chewy at first I thought my card was stolen but turns out $62 is only for the very first order. Will not be using chewy again!

    life changer!

    By pupparooville7 on Feb 9, 2019

    My 9 month old baby Shar pei Gingi Monroe is epileptic and started having seizures at 6 months. This medication has helped her control her episodes and it doesn’t damage her liver. Unlike the phonobarbitol liquid.
