(Ketofen® and Orudis® are other names for this medication.)
Use: Ketoprofen is useful in reducing pain caused by inflammation. It is considered to be safer to use in small animals than aspirin, ibuprofen or acetaminophen. 

Side Effects: Ketoprofen is generally free of side effects but may cause vomiting or diarrhea in some animals. You should report this to your veterinarian immediately if these occur. Ketoprofen can cause bleeding in the gastrointestinal tract. Notify your veterinarian immediately if your pet vomits blood or has feces that appear black or tarry; or if your pet seems lethargic (lacking energy), vomits, or stops eating.

Precautions: Animals with kidney disease should not take ketoprofen as it may worsen the kidney disease. Animals with stomach ulcers or bowel disorders should not take ketoprofen.
Directions: Dogs usually receive ketoprofen orally up to twice daily for pain and inflammation. Cats do not usually receive ketoprofen for more than 5 days as they have a difficult time eliminating it from their bodies. Cats receiving the drug for more than 5 days can cause irreversible damage to the kidneys.

Remember: Ketoprofen should be stored in a tight, light resistant, childproof container away from all children and other household pets.

If you miss a dose of this medication you should give it as soon as you remember it, but if it is within a few hours of the regularly scheduled dose, wait and give it at the regular time. Do not double a dose as this can be toxic to your pet.
