NSAIDs

medicationWhy has my veterinarian prescribed this medicine?

NSAIDs are non-steroidal anti-inflammatory drugs. They are used to treat mild to moderate pain, to reduce inflammation and to reduce fever. Your veterinarian may prescribe NSAIDs to reduce pain in arthritis or following surgical operations. It is difficult to predict which NSAID will help reduce the pain associated with arthritis in a given individual. Your veterinarian may need to try different NSAIDs to find the drug that suits your pet.

Cats, in particular, can easily be overdosed with the NSAID aspirin and you should not give aspirin to your cat without first consulting your veterinarian. Paracetamol is also used for pain relief. Cats cannot change this drug in the body (metabolise), therefore the drug accumulates and is toxic to the cat. Paracetamol should not be given to cats.

Potential side effects

- Although a drug has potential side effects, it does not mean that there is necessarily a high risk of any of these occurring. Tell your veterinarian if you think your pet may be pregnant.

- The commonly reported effects of NSAIDs are mild stomach upset and vomiting. Notify your veterinarian if these side effects appear and remain troublesome. Other potential side effects are skin rashes, liver problems, and changes to the blood. Other side effects may occur, if you notice anything unusual, contact your veterinarian.

Possible drug interactions
