Pig:
Supportive treatment for reduction of pyrexia in combination with, appropriate anti-
infective therapy, if necessary.

Oral powder for top dressing use.
For use in individual pigs on farms where only a small number of pigs are to receive
the veterinary medicinal product.
Pig:
30 mg acetylsalicylic acid (corresponding to 30 mg of the product) per kg BW twice
daily.
The treatment period is 3 consecutive days.
Minimum body weight of pigs to be treated: 11 kg.
Treatment is achieved by mixing the product with approximately 50 g or 200 g
(according to bodyweight) of the normal diet per pig. For measuring the correct
amount of the veterinary medicinal product please use the enclosed scoops
according to the dosage table below. Non-medicated feed should only be offered
after complete consumption of all the medicated feed. Animals should be isolated
from other animals for treatment.
Medicated feed should be freshly prepared before each administration.

Scoops – two scoops measuring 0.4 ml (= 0.33 g of the product) and 3 ml (= 2.25 g
of the product) are supplied.
Part-consumed feed must be disposed of with other waste feed and not given to
other animals.
To avoid overdosing the pigs to be treated should be weighed or body weight
accurately estimated by an experienced person.
Feed consumption may be reduced in clinically sick animals and also in older pigs
therefore feed intake may need to be adjusted to achieve target dosage intake. The
correct quantity of the product should be thoroughly mixed with the feed in a bucket
or similar receptacle. To achieve good mixture and homogeneity a pre-mixture can
be used.
The product should only be added to dry non-pelleted feed. Do not in use in a dry
hopper or a semi liquid feeder.

AN: 01720/2015

Do not use in case of hypersensitivity to the active substance or in cases of
gastrointestinal
irritation and ulcers, chronic gastro-intestinal disorders, bronchospasm, liver function
impairment or nephropathies.
Do not use in pregnant or lactating sows.
Do not use in piglets less than 4 weeks of age.

Gastrointestinal irritation may occur especially in animals with pre-existing
gastrointestinal disease. Such irritation may clinically be manifested by production of
black manure due to blood loss in the gastrointestinal tract.
Inhibition of normal blood clotting may occur incidentally. If this effect occurs it will be
reversible and effects will diminish within approximately 7 days.

In combined treatment with tetracyclines, a treatment interval of at least one hour
between the two active agents is recommended.

Special precautions for use in animals
It must be ensured that the animals consume sufficient water during treatment.
Given that the veterinary medicinal product may inhibit clotting of blood, it is
recommended that elective surgery should not be performed on animals within 7
days after the end of treatment.

Special precautions to be taken by the person administering the veterinary
medicinal product to animals
Do not eat, drink or smoke whilst using this product. Contact via the skin or mucous
membranes of the user must be avoided due to the risk of sensitisation. If you know
that you are allergic to aspirin, avoid contact with this product. Use suitable protective
clothing when using this product, such as gloves and a face mask. Wash hands and
all exposed skin after use.

Penicillins, sulphonamides
As a result of its high plasma protein binding, acetylsalicylic acid may suppress
strongly binding substances such as penicillins and sulphonamides, therefore
potentiating their effect.
Furosemide
The diuretic effect of furosemide is decreased. This may cause symptoms of toxicity
in animals receiving high aspirin doses.
Tetracyclines
Combined administration of buffered acetylsalicylic acid with tetracyclines may lead
to chelate formation.
Aminoglycoside antibiotics
A combination of acetylsalicylic acid and aminoglycoside antibiotics leads to
increased nephrotoxic potential.
Ascorbic acid, methionine, ammonium chloride
Urinary acidification caused by ascorbic acid, methionine or ammonium chloride
leads to decelerated renal salicylic acid secretion with heightened risk of toxic
reactions.
Medicines leading to urinary alkalinisation (sodium hydrogen carbonate)
The renal secretion of salicylic acid is accelerated by the alkalinisation of the urine
(sodium hydrogen carbonate).
Non-steroidal anti-inflammatories
Combination with other NSAIDs leads to increased or intensified occurrence of side
effects, particularly within the gastro-intestinal tract.
Glucocorticoids
Simultaneous administration of glucocorticoids increases the risk of gastro-intestinal
bleeding.
