Frequently asked questions
Is carprofen the same as Rimadyl?
Yes — carprofen is the generic name for the same medication sold as Rimadyl. Both contain the identical active ingredient.
Is generic carprofen as effective as Rimadyl?
FDA-approved generic carprofen must meet the same standards as the brand-name product. Most dogs tolerate them equivalently.
How long can my dog take carprofen?
Many arthritic dogs take carprofen long-term (years) with periodic bloodwork. Always stop and call your vet if any serious side effect appears.
Can RexVet prescribe carprofen?
If the veterinarian decides it is appropriate after a video visit, they can prescribe it where state rules allow.
Can I give carprofen with food?
Yes — and it usually helps reduce stomach upset. Most dogs accept the flavored chewable as a treat.
Is there a generic Rimadyl for dogs?
Yes. Rimadyl is the original brand name; carprofen is the generic name of the same drug, and FDA-approved generic carprofen tablets, chewables and caplets are sold by several manufacturers under other names (Novox, Vetprofen, Carprieve and quellin among them). Every version contains the same active ingredient, carprofen, and has to meet the same FDA standards. All of them are prescription-only, so your vet decides whether carprofen is right for your dog and which product to dispense.
What is the generic name for Rimadyl?
Carprofen. When a vet or pharmacy says 'carprofen', 'generic Rimadyl' or 'carprofen generic', they mean the same non-steroidal anti-inflammatory drug. The brand-name product and the generics differ in maker, tablet shape, flavoring and inactive ingredients, not in the drug itself. Your dog still needs the same baseline bloodwork and periodic rechecks on a generic that it would need on Rimadyl.
Rimadyl vs carprofen: which should my dog get?
Either can be the right choice, and the prescribing vet makes the call. Because the active ingredient is identical, the decision usually comes down to what your pharmacy stocks, which formulation your dog will actually take (a flavored chewable versus a caplet), and whether your dog has done well on one specific product before. Tell your vet if you switch between products so the strength and the monitoring plan stay consistent, and never combine either one with another NSAID or a steroid.
