[Code of Federal Regulations] [Title 21, Volume 6] [Revised as of April 1, 2001] From the U.S. Government Printing Office via GPO Access [CITE: 21CFR520.309] [Page 106] TITLE 21--FOOD AND DRUGS CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN SERVICES--(Continued) PART 520--ORAL DOSAGE FORM NEW ANIMAL DRUGS--Table of Contents Sec. 520.309 Carprofen. (a) Specifications. Each caplet or chewable tablet contains 25, 75, or 100 milligrams of carprofen. (b) Sponsor. See No. 000069 in Sec. 510.600(c) of this chapter. (c) [Reserved] (d) Conditions of use in dogs--(1) Amount. 1 milligram per pound of body weight twice daily. Caplets and chewable tablets are scored and dosage should be calculated and given in half-caplet or half-chewable tablet increments. (2) Indications for use. For the relief of pain and inflammation associated with osteoarthritis in dogs. (3) Limitations. The safe use of carprofen in pregnant dogs, dogs used for breeding purposes, or in lactating bitches has not been established. As a class, cyclo-oxygenase inhibitory nonsteroidal anti- inflammatory drugs (NSAID's) may be associated with gastrointestinal and renal toxicity. Patients at greatest risk for renal toxicity are those on concomitant diuretic therapy, or those with renal, cardiovascular, and/or hepatic dysfunction. Because many NSAID's possess the potential to induce gastrointestinal ulceration, avoid or closely monitor concomitant use of carprofen with other anti-inflammatory drugs, such as corticosteroids and NSAID's. Carprofen treatment was not associated with renal toxicity or gastrointestinal ulceration in safety studies of up to 10 times the dose in dogs. Do not use in dogs with bleeding disorders (e.g., Von Willebrand's disease). Federal law restricts this drug to use by or on the order of a licensed veterinarian.
