Carprofen is a non-steroidal, anti-inflammatory pain reliever that is most commonly used to treat pain associated with chronic arthritis. Carprofen is also used to manage postoperative pain associated with orthopedic and soft tissue surgeries. Although this drug is used in cats, rabbits, and horses, it is most commonly prescribed for use in dogs. It is not typically well tolerated in cats.
Side effects most commonly associated with Carprofen are stomach upset and lethargy.
Carprofen should not be administered in animals with bleeding disorders such as Von Willbrands. This drug should be used with caution in elderly animals and animals with preexisting conditions such as renal disease or inflammatory bowel disease.
Carprofen should not be administered in animals with a known allergy or hypersensitivity to the drug. Carprofen may interact with other medications including Aspirin and Furosemide. This should be discussed with a veterinarian. Emergency veterinary care should be sought if an animal experiences any unusual symptoms.
Carprofen tablets and capsules should be stored in a tight container at room temperature. Injectable forms should be refrigerated. Once broached, the injection may be kept at temperatures of up to 25°C for 28 days.
Carprofen is available in 25 mg, 75 mg, and 100 mg chewable tablets and capsules. Carprofen is also available as a concentrated 50 mg/ml injectable.
A typical dose range for Carprofen in dogs is 4.4 mg/kg PO; which may be given once daily or divided and given as 2.2 mg/kg twice daily as an anti-inflammatory/analgesic. Dose may vary in different species, when the drug is given by a different route or concurrently with other medications, and with regards to a patient's age, breed, and health status. A veterinarian's dosing instructions and/or those printed on the medication label should be followed closely.
If a dose is missed, it should be administered as soon as possible. If it is almost time for the subsequent dose, the missed dose should be skipped and the regular administration schedule resumed. Two doses of Carprofen should not be administered at the same time.
