Carprofen
A veterinary non-steroidal anti-inflammatory drug (NSAID) prescribed to relieve pain and inflammation associated with osteoarthritis and surgery in dogs.
💬 In Plain English
Carprofen is one of the most widely prescribed pain relievers for dogs. It works by selectively blocking inflammatory enzymes (primarily COX-2) that create pain, heat, and swelling in arthritic joints or surgical incisions. By blocking these enzymes, carprofen allows stiff, limping dogs to walk, run, and climb stairs with greater comfort. However, like all NSAIDs, it can occasionally irritate the stomach lining or stress the liver and kidneys, meaning baseline bloodwork is essential before starting long-term use.
🔬 Clinical & Technical Depth
For Vets & TechniciansFormal Clinical Definition
Propionic acid class non-steroidal anti-inflammatory drug exhibiting preferential inhibition of cyclooxygenase-2 (COX-2) over cyclooxygenase-1 (COX-1), providing analgesic, anti-inflammatory, and antipyretic properties while sparing baseline mucosal prostaglandins.
Why Veterinarians Use It
Veterinarians use carprofen as a cornerstone daily analgesic for canine osteoarthritis management and as peri-operative pain control following orthopedic and soft-tissue surgeries.
Clinical Context Encountered
Prescribed frequently after spays, neuters, mass removals, cruciate surgeries, or as an ongoing chewable tablet for senior dogs with stiff joints.
Clinical Reference Guide (Veterinary Medication)
What Owners Must Know
- Administer with a meal to minimize gastrointestinal irritation
- Chewable tablets are highly flavored and palatable to dogs—store securely out of reach in childproof cabinets to prevent catastrophic accidental overdose
- Never combine with aspirin, ibuprofen, or steroid medications
Potential Side Effects
- Vomiting, diarrhea, and decreased appetite
- Gastric ulceration and dark tarry stools (melena)
- Idiosyncratic hepatotoxicity (rare severe liver reaction, historically over-reported in Labrador Retrievers)
- Renal papillary necrosis in dehydrated or hypotensive patients
- •DO NOT give carprofen to cats: felines have limited glucuronidation pathways and cannot metabolize carprofen safely, risking acute kidney and liver failure.
- •Stop carprofen immediately and call your vet if your dog experiences vomiting, dark tarry stools, loss of appetite, or yellowing of the eyes.
❓ Questions to Ask Your Veterinarian
Take these actionable questions with you to your next clinic visit or appointment:
- 1Has my dog had baseline bloodwork (liver and kidney chemistry) run recently?
- 2How frequently will we recheck bloodwork while my dog is on daily carprofen (typically every 6 to 12 months)?
- 3What are the early warning signs of gastrointestinal stomach upset or ulceration?
- 4Can carprofen be given with a meal to protect the stomach?
