Carprofen
Generic Name: carprofen
Brand Name: Rimadyl
While carprofen, an NSAID, is approved for use to treat pain and inflammation in some animals, chronic use may cause toxicity. It is important to discontinue use of prescribed NSAIDs when your veterinarian tells you to do so. Toxicity can also occur if you pet consumes more medication than prescribed.
It is important to note that other veterinary NSAIDs (such as deracoxib, firocoxib, ketoprofen, meloxicam and tepoxalin) carry similar toxicity risks.
Signs and symptoms of toxicity: vomiting, abdominal pain, melena (black, tarry stool), diarrhea. These signs may occur within an hour of ingestion. Weakness, involuntary muscle movements, and seizures may also occur and these are signs of severe toxicity.
More severe toxicity (GI perforation or renal failure) may not occur until 48-72 hours after ingestion. Signs of kidney damage include increased thirst, increased urination, loss of appetite or refusal to eat, fatigue, and vomiting.
Toxic consumption:
Doses greater than 5 times the therapeutic dose can result in toxicity.
In cats, acute or chronic doses of any medication may cause toxicity.
In dogs, signs of toxicity can be seen with doses of 22 mg/kg.
Long term use, even at therapeutic doses, can result in clinical signs of toxicity.
