Safety of Rimadyl

Rimadyl is the brand name for the veterinary prescription medication carprofen. Despite its effectiveness in treating the pain of arthritis in dogs and cats, Rimadyl poses a risk for side effects in some animals.

  1. Types of Risks

    • Rimadyl has the potential to cause damage to a dog's digestive system, kidneys or liver, reports Mar Vista Animal Medical Center.

    Symptoms

    • According to PetPlace.com, symptoms of adverse effects from Rimadyl include vomiting, loss of appetite, diarrhea, black stools, lethargy and light-colored urine.

    Significance

    • Mar Vista Animal Medical Center maintains that only 1 out of every 1000 dogs develops an idiosyncratic reaction to Rimadyl. An idiosyncratic reaction is one that is not dependent on dose or on any other apparent factor.

    Features

    • Most cases of liver or kidney toxicity or digestive tract ulceration from Rimadyl occur due to excessive doses of the medication, reports PetPlace.com.

    Considerations

    • Dogs with a history of kidney or liver disease, Von Willebrand's disease or allergic reactions to non-steroidal anti-inflammatory medications may not be able to safely take Rimadyl, cautions Pfizer, the maker of Rimadyl. In addition, some drugs for heart disease and epilepsy in dogs may increase the risk of damage to the kidneys or liver when taken with Rimadyl.
