Great service, SoSo pricing

Theophylline has been hard to find. The first Rx I bought from a different company and it took 5 days to get the med. My dog had great trouble breathing over the weekend while I waited. I changed to Chewy Pharmacy and her meds have always been shipped within 24 hours. I'm only baffled by the fact that a 300mg tablet costs more than twice the cost of a 400mg tablet. It just doesn't make sense. I love the Chewy service.

Love the Price

My emotional support dog has an enlarged heart. This medication was $111 for 30 at my local pharmacy. Chewy’s price is less than half of that. I’m on a fixed income but I would do or pay anything for Buddy’s health. The lower price has definitely helped me. I was already buying a lot from Chewy and was surprised when my veterinarian suggested checking their prices. Chewy is great!

You can find a smaller dose...

My 6 lb dog is on a much smaller dose than offered through Chewy's. My vet found a local compounding pharmacy that makes the liquid suspension. They also ship out of state. Ask your vet about compounding pharmacies.

Needed 100mg - so no order

Aside from lack of choice of strength - pricing per pill is just strange. My vet was out of this med, guess I'll just wait till they get it back in stock. Disappointed....

Returning this order.

There seems a problem with the size of this pill? There is no possible way, (no matter how you crush it down ) that is can give this to my cat. Could their be maybe a liquid that i purchase instead of this pill? Anyhow I'll be returning this item. Thank you very much.
