4.4. Special warnings for each target species


4.5. Special precautions for use.

Special precautions for use in animals

Avoid intra-arterial injection.

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 product in the immediate post-partum period may

interfere with uterine involution and expulsion of foetal membranes resulting in

retained placentae. See also section 4.7.

Use in any animal less than 6 weeks of age or in aged animals may involve

additional risk. If such use cannot be avoided animals may require a reduced

dosage and careful clinical management.

Do not use in dehydrated or hypovolaemic animals except in the case of

endotoxaemia or septic shock.

It is preferable that NSAIDs which inhibit prostaglandin synthesis are not

administered to animals undergoing general anaesthesia until fully recovered.

The cause of the inflammatory condition or colic should be determined and treated

with appropriate concurrent therapy.

The product should not be used in piglets weighing less than 6 kg.

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

Flunixin meglumine is a non-steroidal anti-inflammatory drug (NSAID).

The product may cause an allergic reaction in people sensitised to NSAIDs.

People with known hypersensitivity to NSAIDs should avoid contact with the

product. Hypersensitivity reactions may be serious.

This product may cause skin and eye irritation.

Avoid contact with skin or eyes.

In case of skin or eye contact, wash exposed area with plenty of clean

water. If symptoms persist, seek medical advice.

In case of accidental self-injection, seek medical advice immediately and

show the package leaflet or the label to the physician.

Do not eat or drink when using the product.

Wash hands after use.

4.6. Adverse reactions (frequency and seriousness)

Adverse reactions include gastro-intestinal irritation, ulceration and, in dehydrated or

hypovolaemic animals, potential for renal damage.

In pigs transient irritation may occur at the injection site, this resolves spontaneously

within 14 days.

As with other non-steriodal anti-inflammatory drugs, idiosyncratic renal or hepatic

adverse effects may be observed.

4.7. Use during pregnancy, lactation or lay

The product may be used in pregnant and lactating cattle.

The product should only be administered within the first 36 hours post-partum

following a benefit/risk assessment performed by the responsible veterinarian and

treated animals should be monitored for retained placentae.

Do not use in pregnant mares or pregnant sows. Safety studies in pregnant mares

and pregnant sows have not been conducted.

4.8. Interaction with other medicinal products and other forms of interaction

Do not administer other NSAIDs concurrently or within 24 hours of each other.

Some NSAIDs may be highly bound to plasma proteins and compete with other

highly bound drugs which can lead to toxic effects.







aminoglycosides, should be avoided.

The concurrent administration of corticoids may increase toxicity of the two products

and increase the risk of gastro-intestinal ulceration. It should therefore be avoided.

Flunixin may reduce the effect of some anti-hypertensive medicinal products, such

as diuretics, angiotensin conversion enzyme (ACE) inhibitors, and beta blockers, by

inhibition of prostaglandin synthesis.

4.9. Amounts to be administered and administration route


2.2 mg flunixin per kg bodyweight (equivalent to 2 ml of product per 45 kg BW)

administered intravenously. Repeat as necessary at 24 hour intervals for up to 5

consecutive days.


By intravenous injection for musculo-skeletal disorders at the following rate:

1.1 mg flunixin per kg

bodyweight (equivalent to 1 ml of product per 45 kg BW)

once daily for up to 5 days according to clinical response.

By intravenous injection for colic at the following rate:

1.1 mg flunixin per kg

bodyweight (equivalent to 1 ml of product per 45 kg BW)

repeated once or twice if colic recurs.

For the treatment of endotoxaemia or septic shock associated with gastric torsion

and with other conditions in which the circulation of blood to the gastro-intestinal

tract is compromised: 0.25 mg/kg every 6-8 hours, by intravenous injection.

2.2 mg flunixin

per kg bodyweight (equivalent to 2 ml of product per 45 kg BW)

once by intramuscular injection, in the neck, in conjunction with appropriate

antimicrobial therapy. The injection volume should be limited to a maximum of 5 ml

per injection site.

An appropriately graduated syringe must be used to allow accurate administration of

the required dose volume. This is particularly important when injecting small


When intramuscular injection is used, the dose should be divided between two

injection sites on either side of the neck.

In order to prevent excessive broaching of the rubber stopper, the 50 ml and 100 ml

vials should not be broached more than 25 times and the 250 ml vial not more than

50 times.

4.10. Overdose (symptoms, emergency procedures, antidotes), if necessary

Overdosage studies in the target species have shown the product to be well-

tolerated. Flunixin meglumine is a non-steroidal anti-inflammatory drug. Overdosage

is associated with gastrointestinal toxicity. Concurrent use of nephrotoxic drugs

should be avoided.

4.11. Withdrawal period(s)

Cattle (meat and offal):

5 days

Cattle (milk)

24 hours

Horses (meat and offal):

7 days

Pigs (meat and offal):

22 days

rheumatic products, non-steriods, flunixin

5.1. Pharmacodynamic properties

Flunixin meglumine is a non steroidal antiinflamatory drug (NSAID) with anti-

inflammatory, analgesic and anti-pyretic properties.

5.2. Pharmacokinetic properties

Following flunixing meglumine administration to horses by intravenous route at dose

1,1 mg/kg a bicompartmental kinetic pattern was established . It showed a rapid

distribution and a high degree of protein binding. The elimination half life is short 1-2

h. AUC


was 19.43 mg-h/ml. Excretion quickly took place, mainly via urine.

In cattle, after intravenous administration of 2.2 mg / kg, peak plasma levels

between 15 and 18

g / ml were obtained after 5 to 10 minutes after injection.

Page 4 of 6

Issued: December 2017

AN: 00904/2016

Between 2 and 4 hours after administration, a second peak plasma concentration

(possibly due to enterohepatic circulation) was observed. Flunixin meglumine is

rapidly distributed to organs and body fluids (with high persistence in the

inflammatory exudate), with a high distribution volume. The elimination half-life was

approximately 4 to 7 hours. Excretion took place mainly through urine and faeces. In

milk, the drug was not detected, and where it was detected, the levels were

insignificant (<10 ng / ml).

In pigs following the intramuscular administration of flunixin meglumine the drug is

completely absorbed, extensively distributed and eliminated slowly.

Excretion (mostly as unchanged drug) took place primarily in the urine, although it

was also detected in the faeces.
