Mild reactions at the injection site characterised by swelling and associated with
perivascular inflammation have been reported in clinical studies following
administration of the product at the recommended dose. There is potential for
the injection site reaction to be associated with pain.
Lesions (erosion/ulceration) of the oral mucosa and of the skin around the mouth were
very commonly observed in treated animals during tolerance studies. These lesions
were mild and resolved without treatment. Salivation and labial and tongue oedema
have been uncommonly associated with the oral lesions in a field study.

Special precautions for use in animals
Do not use in animals less than 10 weeks of age.
Avoid use in any dehydrated, hypovolaemic or hypotensive animal, as there may
be potential risk of increased renal toxicity. Concurrent administration of potentially
nephrotoxic veterinary medicinal products should be avoided. Do not exceed the
recommended dose or duration of treatment.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
In case of accidental self-injection, seek medical advice immediately and show the
package leaflet or the label to the physician.
Avoid contact with eyes and skin. If this occurs, rinse affected area
immediately with water. Wash hands after use of the veterinary medicinal
product.
Like other medicinal products that inhibit COX-2, pregnant women or women
attempting to conceive should avoid contact with, or wear disposable gloves, when
administering the veterinary medicinal product.
Other NSAIDs, diuretics and substances that have a high degree of protein binding
may compete for binding and lead to toxic effects. Do not use concomitantly with
corticosteroids or other NSAIDs.
Pre-treatment with other anti-inflammatory substances may result in additional or
increased adverse reactions and a treatment-free period with such medicinal
products should therefore be observed. The treatment-free period should take into
account the pharmacological properties of the medicinal products used previously.
Concurrent administration of potentially nephrotoxic medicinal products should be
avoided as there might be an increased risk of renal toxicity. Concomitant
treatment with molecules displaying action on renal flow (e.g. diuretics) should be
subject to clinical monitoring.
This veterinary medicinal product does not require any special storage conditions.
Meat and offal: 26 days
Not authorized for use in animals producing milk for human consumption.
