Compare the same drug, strength, and quantity. Your veterinarian can refuse to authorize a particular pharmacy, and a new exam is sometimes required before a refill.

Ask the clinic which pharmacies it will authorize before you create an account. The price on the website becomes a fill only after the veterinarian approves that pharmacy.

Common Questions

Which option is the best value?

Value is the prescribed product, at a price you can see before you pay, from a pharmacy licensed to ship it to you. A cheaper listing for a different strength is not the same order.

Can I switch later?

You can send the next refill to a different pharmacy. The clinic has to authorize that pharmacy. Do not create another strength by splitting tablets.
