Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or the national competent authority via the
national reporting system. See the package leaflet for respective contact details.

Treatment of calves with the veterinary medicinal product 20 minutes before
dehorning reduces post-operative pain. The veterinary medicinal product alone will
not provide adequate pain relief during the dehorning procedure. To obtain adequate
pain relief during surgery co-medication with an appropriate analgesic is needed.

Special precautions for safe use in the target species:
If adverse reactions occur, treatment should be discontinued and the advice of a
veterinarian should be sought.
Avoid use in very severely dehydrated, hypovolaemic or hypotensive animals which
require parenteral rehydration, as there may be a potential risk of renal toxicity.
In case of inadequate relief of pain when used in the treatment of equine colic,
careful re-evaluation of the diagnosis should be made as this could indicate the need
for surgical intervention.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Accidental self-injection may give rise to pain. Meloxicam and other non-steroidal
anti-inflammatory drugs (NSAIDs) may cause hypersensitivity (allergic reactions).
People with known hypersensitivity to NSAIDs should avoid contact with the
veterinary medicinal product. In case of accidental self-injection, seek medical advice
immediately and show the package leaflet or the label to the physician.
This veterinary medicinal product may cause eye irritation. In case of contact with the
eyes, immediately rinse thoroughly with water.
In view of the risk of accidental self-injection and the known adverse class-effects of
NSAIDs and other prostaglandin inhibitors on pregnancy and/or embryofoetal
development, this veterinary medicinal product should not be administered by
pregnant women or women attempting to conceive.
Special precautions for the protection of the environment:
Not applicable.

Do not administer concurrently with glucocorticosteroids, other non-steroidal anti-
inflammatory drugs or with anticoagulant agents.

This veterinary medicinal product does not require any special storage conditions.
