As with every drug therapy it is important to learn about Rimadyl before giving it to your canine companion.  You should familiarize yourself with the indications instructions and possible side effects before starting any new prescription.  Rimadyl is a non-steroidal anti-inflammatory drug (NSAID) that is used to reduce pain and inflammation (soreness) due to osteoarthritis and pain following surgery in dogs. Rimadyl is a prescription drug for dogs. It is available as a caplet and chewable tablet and is given to dogs by mouth or in an injectable formula administered by veterinarians.  

Your dog should not be given Rimadyl if he/she has had an allergic reaction to carprofen (the active ingredient of Rimadyl) or aspirin.   Tell your veterinarian if your dog has ever had the following medical problems:   digestive upset (vomiting and/or diarrhea) liver disease kidney disease or any bleeding disorder.   While Rimadyl is not a cure for osteoarthritis it can relieve the pain and inflammation and improve mobility.  Rimadyl like other drugs may cause some side effects. Serious but rare side effects have been reported in less than .02% of dogs taking Rimadyl. Serious side effects can occur with or without warning and in rare situations result in death.   The most common side effects generally involve the stomach (such as bleeding ulcers) and liver or kidney problems. Other side effects that may indicate a negative reaction to Rimadyl or another medical problem include appetite change vomiting change in bowel movements or behavior jaundice and sores on the skin. 

It is important to stop therapy and contact your veterinarian immediately if you think your dog has a medical problem or side effect from Rimadyl therapy. If you have additional questions about possible side effects talk to your veterinarian.
