Major Indication:


  • Nonsteroidal Anti-inflammatory Drug (NSAID)
    • Painkiller, anti-inflammatory, antipyretic (reduces fever)
  • Used after injury or surgery.
  • Can be used long-term to treat chronically painful conditions (e.g., osteoarthritis).


Common Contraindications and Warnings:


  • The drug should not be given to dehydrated animals, those with low blood pressure, or those with a clotting disorder.
  • Care is needed in older patients with pre-existing kidney disease, intestinal disease, or liver disease.
  • Safety has not been determined in puppies younger than 6 months or in pregnant or lactating dogs.
  • Do not administer alongside any other NSAID or steroid (e.g., prednisone) and do not change NSAIDs until your pet has gone through a 7-day washout period of no Carprofen.


Potential Side Effects:


  • The most common side effects are vomiting and/or diarrhea (less than 2%).
  • Rare side effects include liver or kidney failure, bleeding, and intestinal ulceration.
  • Animals that develop side effects often tolerate a different NSAID.
  • There is little evidence to suggest one particular NSAID has a better safety profile than another.


Administration Instructions/Handling:


  • Give with food.
  • Stop if your dog develops vomiting or diarrhea, or if it becomes unwell during treatment.
  • Tablets can be very palatable, so it is important to keep them well out of reach of your dog.
  • If a dose is missed, give straight away if within a couple of hours of normal dosing time, otherwise restart when the next dose is due.




  • Store at room temperature and out of reach of dogs. The tablets can be very palatable, and whole bottles may be eaten if they are accessible.


Speed of Action + Monitoring:


  • NSAIDs start working within a few hours. In chronic pain conditions, it can take several weeks for the full benefit to be seen.
  • Pain levels should also be closely monitored to be certain no additional treatment is needed.
  • With long-term use, intermittent blood testing is routinely recommended to monitor liver and kidney function.
  • When given to treat pain, your pet’s pain levels should be monitored to ensure the treatment given is effective.
