Rimadyl for Dogs

Important disclaimer
This is general information, not veterinary advice. Always consult a licensed veterinarian before giving your pet any medication.

Rimadyl is the original brand-name carprofen product, introduced in the 1990s and still one of the most widely recognized NSAIDs in veterinary medicine — the "dog medicine Rimadyl" a lot of owners first hear about at a checkup. This guide covers what Rimadyl treats, its available strengths, typical cost, whether it's sold over the counter, and how it relates to generic carprofen.

What Is Rimadyl?

Rimadyl (carprofen) is an NSAID approved by the FDA for managing pain and inflammation in dogs, most commonly for osteoarthritis and post-surgical recovery. It's manufactured by Zoetis and available as a chewable tablet (flavored) and a caplet, in 25mg, 75mg, and 100mg strengths (with 50mg available in some related product lines). Vets prescribe Rimadyl for the same core uses as any carprofen product: long-term arthritis pain management and short-course post-surgical pain and inflammation control. See our complete carprofen for dogs guide for the underlying mechanism.

Is Rimadyl Available Over the Counter?

No. Despite being one of the most recognized names in veterinary pain medication, Rimadyl for dogs is not available over the counter under any circumstance in the U.S. — it requires a valid prescription from a licensed veterinarian, the same as every generic carprofen product. If you've seen "Rimadyl for dogs without vet prescription" in search results, treat that as a red flag rather than a shortcut; see our full explanation on why a prescription is required.

Rimadyl Cost

Because Rimadyl is the branded product, it's generally priced higher than generic carprofen equivalents like Novox or Vetprofen. Many pet owners ask their vet whether a generic substitution is appropriate to reduce the cost of long-term arthritis management, especially since Rimadyl and generic carprofen are considered therapeutically equivalent (see our full brand vs generic comparison). Compare current pricing on our where to buy carprofen page, and see our cost and insurance guide for ways pet insurance may offset the expense.

Prescription required Rimadyl requires a prescription

Like all carprofen products, Rimadyl is prescription-only. See our guide on why a prescription is required if you're trying to understand the process.
