Rimadyl for Dogs: Pain Relief and Risks Explained
Rimadyl (carprofen) is an FDA-approved NSAID for dogs that reduces pain and inflammation, commonly used for arthritis and post-surgical pain relief.
If your dog has been prescribed Rimadyl, you may be wondering what it's for and what to expect. Rimadyl (generic name: carprofen) is one of the most commonly used pain relief medications in dogs. This guide explains how it works, what it treats, possible side effects, and how to keep your dog safe while taking it.
What Is Rimadyl?
Rimadyl is a non-steroidal anti-inflammatory drug (NSAID) approved for dogs. It reduces pain and inflammation by blocking enzymes involved in the inflammatory process. Unlike steroids such as prednisone, Rimadyl specifically targets pain pathways and is used mostly for joint and post-surgical pain.
Key Facts About Rimadyl:
- Generic Name: Carprofen
- Drug Class: Non-steroidal anti-inflammatory drug (NSAID)
- FDA Status: Approved specifically for dogs
- Available Forms: Chewable tablets, caplets, injectable
- Common Uses: Arthritis, post-surgical pain
Why Do Vets Prescribe Rimadyl?
Rimadyl is most commonly prescribed for:
- • Osteoarthritis: to relieve pain and stiffness in aging or arthritic dogs
- • Post-surgical pain: often given after spays, neuters, or orthopedic procedures
- • Musculoskeletal injuries: sprains, strains, or soft tissue injuries
Some dogs take Rimadyl short-term, while others may use it long-term to manage chronic arthritis. For dogs with severe pain that may also require anti-inflammatory treatment, veterinarians must carefully choose between NSAIDs like Rimadyl and corticosteroids such as prednisone, as they cannot be used together safely.
Common Side Effects of Rimadyl in Dogs
Most dogs tolerate Rimadyl well, but as with all NSAIDs, there are risks. Common side effects include:
- • Vomiting or diarrhea
- • Loss of appetite
- • Lethargy
- • Black or tarry stools (a sign of stomach bleeding)
Serious Side Effects (Less Common):
- • Stomach ulcers
- • Liver enzyme elevations (learn about high ALT in dogs)
- • Kidney issues
- • Gastrointestinal bleeding
Need to monitor your dog's response to Rimadyl?
Use VetLens to track your dog's pain levels, monitor side effects, and organize bloodwork results for safer long-term NSAID use.
Try VetLens FreeSafety and Monitoring
Your vet will usually recommend baseline bloodwork before starting Rimadyl, especially for older dogs, and periodic rechecks to monitor liver and kidney values.
⚠️ Important Drug Interactions:
Rimadyl should not be combined with other NSAIDs (like Deramaxx, Meloxicam) or with steroids (like prednisone), as this greatly increases the risk of ulcers and bleeding.
What to Watch for at Home
Call your vet if you notice vomiting, diarrhea, loss of appetite, black stools, jaundice (yellow gums/eyes), or increased drinking and urination while your dog is on Rimadyl. Stopping the drug early and switching to another pain management option may prevent more serious complications.

Frequently Asked Questions
Is Rimadyl safe for long-term use?
Yes, many dogs take Rimadyl for years. Regular bloodwork is important to monitor for side effects, especially liver and kidney function.
Can I give Rimadyl to my cat?
No, Rimadyl is not approved for cats and can be dangerous. Cats metabolize NSAIDs very differently than dogs and are at much higher risk for serious side effects.
What should I do if I miss a dose?
Give the missed dose as soon as you remember, unless it's almost time for the next one. Do not double up on doses, as this increases the risk of side effects.
Can Rimadyl cure arthritis?
No, it doesn't cure arthritis but can greatly improve comfort and mobility by reducing pain and inflammation in the joints.
