Side Effects of NSAID's Pain Medications in Dogs

Updated on July 25, 2009

Just as in human medicine, many drugs given to dogs may appear to help with something, while potentially harming something else. This case scenario in particular seems to be very accurate when it comes to giving dogs Non Steroidal Anti Inflammatory drugs often abbreviated by the acronym NSAID. These drugs come with a long list of potential side effects  and complications, therefore, they must be prescribed only through the guidance of a veterinarian and the dog must be monitored.

NSAID's are named this way to distinguish them from steroid drugs. While they are mostly given to reduce pain, inflammation and fever, they are not narcotic drugs. Many dogs have benefited from the use of such drugs for arthritis relief,  post surgical pain and to reduce inflammatory states. In order for a dog to receive a prescription for NSAID's, the veterinarian must perform a thorough physical examination and it is recommend that blood work is ran before and during the administration of such drugs.

Common NSAID's prescribed in dogs may consist of the following:  Etogesic, Rimadyl, Previcox, Deramaxx, Zubrin, Novox and Metacam. Over the counter NSAID's for human use should never be given to dogs as many of them are toxic. There are several reports each year of dog owners causing serious harm to their dogs by giving Tylenol. While Aspirin can be given to dogs, it should be given only under the strict guidance of a veterinarian because being an NSAID, it may as well carry a long list of side effects.

Side Effects From NSAID's

The most common complications deriving from the use of NSAID's in dogs consist of gastro-intestinal problems due to the NSAID's ability to reduce mucous protection of the stomach creating a fertile ground for ulcers, along with rare risks for kidney and liver problems. In particular, Labrador Retrievers appear to be more prone than other breeds to liver complications from the use of such medications. Owners should report to their veterinarian immediately upon noticing the following symptoms:

-Loss of Appetite



-Black, Tarry Stools

-Presence of blood in vomit or feces

-Jaundice (yellowing of eyes, ears,  gum, abdominal skin)

-Increased Drinking

-Increased Urination

-Behavior Changes

There may be more side effects depending on the type of drug used. Owners should therefore, carefully read the labeling and be watchful for potential signs of complications. Each time an NSAID is prescribed it should come with a Client Information Sheet. This sheet  should also display a toll free number to call in case there are any side effects to be reported or questions.

To take a further step in case of significant  Adverse Drug Experiences (ADE), owners and veterinarians should report them to the Center for Veterinary medicine. This contact information is available below:

While NSAID's may have saved various lives of dogs with severe cases of unmanageable osteoarthritis, there are reports of dogs becoming seriously ill and even dying from its side effects. The only way to prevent this from happening is through educating dog owners about potential side effects, having them read the client information sheet and carefully monitoring their dogs. It is very important for dog owners to request blood screenings before and after  the administration of NSAID's in case their vet refrains from offering them and last but no least,  owners should carefully monitor their dogs and always report any abnormalities immediately without delay.

      That's quite upsetting, I wonder if it's a side effect or a worsening of an underlying orthopedic condition, let us know what it turns out being. Keeping your dog in my thoughts.

      I already mentioned this in my hub but it is worth saying it many times because still too many people tend to reach for over the counter meds for their dogs often ending up with a call to poison control and a trip to the emergency vet.

      I would not recommend the use of any NSAID for a dog. You must remember that if you purchase an over the counter NSAID, the side effects printed on the package are for people, not dogs. If your pet is prescribed steroid or non-steroid drugs, a search on google for it's side effects is quick and easy.
