Rimadyl can cause side effects, although many dogs tolerate it well when it is used as prescribed. The most commonly reported problems involve the digestive system and may include loss of appetite, vomiting, diarrhea, or changes in stool.
Some dogs may also become unusually tired, less active, restless, or show changes in their normal behaviour. Contact your veterinarian if you notice any new or concerning symptoms while your dog is taking Rimadyl.
Serious side effects
Less commonly, Rimadyl can cause serious problems involving the stomach or intestines, kidneys, or liver. These reactions can sometimes become severe, so early veterinary attention is important.
Stop giving Rimadyl and contact your veterinarian promptly if your dog develops repeated vomiting, persistent diarrhea, black or bloody stools, a major loss of appetite, unusual weakness, increased thirst, changes in urination, yellowing of the eyes or gums, or significant changes in behaviour.
Should Rimadyl be given with food?
Rimadyl may be given with or without food. However, giving it with a meal may help reduce nausea or stomach discomfort in some dogs.
Follow the instructions provided by your veterinarian. Do not give an extra dose if your dog vomits shortly after taking the medication unless your veterinarian specifically tells you to do so.
Monitoring during long-term treatment
Dogs taking Rimadyl for an extended period should have regular veterinary checkups. Your veterinarian may recommend blood tests before treatment begins and periodically during treatment to monitor liver and kidney function.
These appointments also allow your veterinarian to check whether Rimadyl is still controlling your dog’s pain and whether the dose remains appropriate.
Signs that your dog may not tolerate carprofen
Signs of carprofen intolerance may include loss of appetite, vomiting, diarrhea, black or bloody stools, reduced activity, unusual tiredness, increased drinking, changes in urination, or yellowing of the skin, gums, or eyes.
These symptoms should not be ignored. Stop the medication and contact your veterinarian for instructions if they occur.
Using Rimadyl safely
Rimadyl can provide important relief from pain and inflammation, but like all NSAIDs, it can also cause harmful effects in some dogs. The risk is greater if the dose is too high, the medication is given for longer than recommended, or it is combined with another NSAID or a corticosteroid.
Give only the amount prescribed by your veterinarian and follow the recommended schedule. Do not give aspirin, ibuprofen, naproxen, another veterinary NSAID, or a steroid such as prednisone unless your veterinarian specifically approves it.
Tell your veterinarian about all medications, supplements, and health conditions your dog has. Your veterinarian will determine the safest dose, explain possible interactions, and advise you about any monitoring your dog may need.
