Ketofen for Cats

Ketofen, a brand name of the drug ketoprofen, is an anti-inflammatory used veterinary medicine. The drug itself is also approved for use in humans, although it appears under other brand names such as Orudis and Actron. Veterinarians typically prescribe Ketofen to aid in post-operative treatment or to relieve symptoms associated with arthritis, but it is a versatile drug that has a variety of applications for use in cats. Continue reading for a brief overview of the uses and side effects of Ketofen in feline medicine.


Ketofen is classified as a non-steroidal anti-inflammatory drug, or NSAID. These drugs offer a similar effect to steroids without some of the harmful side effects of those powerful medicines. NSAIDs like Ketofen reduce swelling and inflammation caused by a wide variety of underlying diseases and conditions. Some of the other most common NSAIDs are aspirin and ibuprofen.

In certain circumstances, the body produces a chemical called prostaglandin, which causes inflammation and soreness. Ketofen works to relieve these symptoms by inhibiting the production of this chemical compound.

Ketofen for Use in Cats

You may purchase Ketofen over the counter at a pharmacy or pet store. However, though the drug is available without a veterinary prescription, it is best if you do not attempt to treat your pet's condition with Ketofen unless you have first consulted with a vet. The reason for this is that there may be prescription drug alternatives that will be better able to address your cat's specific condition. Additionally, if your cat has allergies or certain other medicines in his system, Ketofen may cause adverse effects.

In veterinary use, Ketofen is used not only to relieve arthritis pain and other types of inflammation, but also as a pain reliever during post-operative care and rehabilitation. Ketofen is well suited to this purpose because it is associated with a limited number of adverse effects. These include the following:


  • Vomiting and diarrhea
  • Loss of appetite
  • Lethargy


In some rare cases, Ketofen can also exacerbate or cause stomach and kidney ulcerations. This is a serious matter and is a reason to have your pet examined regularly by a veterinarian while he is on a Ketofen treatment regimen. If your pet has a preexisting ulcer or related condition, do not use Ketofen to treat his inflammation or swelling.

Ketofen is available in an oral tablet. The exact dose depends upon the size, weight and age of your pet, as well as his condition and the severity of the symptoms. Consult with a pharmacist or your veterinarian for dosage instructions. As with other medicines, it is important to continue your pet's treatment regimen through to completion. However, if your cat has one or more negative reactions to Ketofen, or if his condition seems to not improve or to worsen, take him to a veterinarian immediately.

Arthritis is one of many causes of painful swelling and inflammation in older cats. Use Ketofen with your veterinarian's approval to help moderate those symptoms and to restore your pet's mobility and way of life.
