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 its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.

None.

Special precautions for safe use in the target species
Inject slowly as life threating symptoms of shock can occur due to the content of
propylene glycol.
Non-steroidal anti-inflammatory drugs (NSAIDs) are known to have the potential to
delay parturition through a tocolytic effect by inhibiting prostaglandins that are
important in signalling the initiation of parturition. The use of the veterinary medicinal
product in the immediate post-partum period may interfere with uterine involution and
expulsion of foetal membranes resulting in retained placentae.
The veterinary medicinal product should have a temperature close to body
temperature. Stop injection immediately after first symptoms of shock and start shock
treatment if necessary.
Use of NSAIDs in hypovolemic animals or animals with shock should be subject to a
benefit-risk evaluation performed by the responsible veterinarian due to the risk of
renal toxicity.
Use in very young (cattle, horses: less than 6 weeks old) as well as in old animals
may involve additional risks. If such treatment cannot be avoided, careful clinical
observation is indicated. The underlying cause of pain, inflammation or colic should
be determined and, when appropriate, antibiotic or re-hydration therapy should be
given concurrently.
NSAIDs can cause phagocytosis inhibition and, therefore, in the treatment of
inflammatory states associated with bacterial infections, appropriate concurrent
antimicrobial therapy should be established.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
This veterinary medicinal product may cause hypersensitivity (allergy) reactions.
People with known hypersensitivity to non-steroidal anti-inflammatory drugs such as
flunixin and/or to propylene glycol should avoid contact with the veterinary medicinal
product. In case of hypersensitivity reactions seek medical advice and show the
package leaflet or the label to the physician.
This veterinary medicinal product may cause skin and eye irritation. Avoid contact with
skin or eyes.
Wash hands after use. In case of accidental skin contact, wash affected area
immediately with plenty of water.
In case of accidental eye contact, rinse eyes immediately with plenty of water. If skin
and /or eye irritation persists, seek medical advice immediately and show the package
leaflet or the label to the physician.
Accidental self-injection may cause pain and inflammation. In case of accidental self-
injection, seek medical advice immediately and show the package leaflet or the label
to the physician.
Laboratory studies in rats with flunixin have shown evidence of foetotoxic effects.
Pregnant women should use the veterinary medicinal product with serious caution to
avoid accidental self-injection.
Special precautions for the protection of the environment:
Flunixin is toxic to avian scavengers. Do not administer to animals susceptible to
enter wild fauna food chain. In case of death or sacrifice of treated animals, ensure
that they are not made available to wild fauna.

Do not administer other non-steroidal anti-inflammatory drugs (NSAIDs) concurrently
or within 24 hours of each other. Do not administer corticosteroids concurrently.
Concurrent use of other NSAIDs or corticosteroids may increase the risk of gastro-
intestinal ulceration.
Some NSAIDs may be highly bound to plasma proteins and compete with other
highly bound drugs which can lead to toxic effects.
Flunixin may decrease the effect of some antihypertensive drugs by inhibiting
prostaglandin synthesis, such as diuretics, ACE inhibitors (angiotensin converting
enzyme inhibitors) and beta blockers.
Concomitant administration of potentially nephrotoxic drugs (e.g., aminoglycoside
antibiotics), should be avoided.

Do not store above 25°C after first opening the immediate packaging.
