About This Item

Details

  • The most commonly used selective beta blocker in veterinary medicine which slows the heart rate, reduces heart contraction force, and calms electrical activity to manage heart rhythm issues.

Very small pills

I have to cut these in quarters to get the right dose and the pill is so small it's like micro surgury to do it. Either need bigger pills or different dosage op

Very easy to order.

Much less expensive than the vet and it saves me a trip to the vet. My cat has been on this medicine for years. I wish I ordered from Chewy sooner.

Delivery was excellent,

These don't look like the pills which I got from the vet's office so I'm a bit worried about the suitability for my ailing dog.

Convenient and Reasonably Priced

It's so much easier to get this medication from Chewy than from the local drugstore. Also the price is better!
