Precautions and Side Effects
While generally safe and effective when prescribed by a veterinarian, naproxen can cause side effects in some animals. Since the toxic level is very close to the therapeutic level in dogs and cats, it is rarely recommended in these species.
Naproxen should not be used in animals with known hypersensitivity or allergy to the drug.
Naproxen should not be used in animals with known kidney, blood or liver disorders. It should not be used in animals with pre-existing stomach ulcers.
Naproxen may interact with other medications. Consult with your veterinarian to determine if other drugs your pet is receiving could interact with naproxen . Such drugs include aspirin, other NSAIDs, corticosteroids and furosemide.
The most common adverse effects are bleeding gastric ulcers and kidney problems in dogs and cats.

There is no safe dose for cats.
