4.1 Target species
Porcine: pigs for fattening (up to 40 kg bodyweight)
4.2 Indications for use, specifying the target species
Symptomatic treatment of fever appearing as a concomitant sign of respiratory diseases of viral origin in combination with an appropriate anti-infective therapy, if necessary.
4.3 Contraindications

4.4 Special warnings for each target species
The intake of medicated water by animals may be altered as a consequence of illness. In case of insufficient water intake, animals should be treated parenterally instead.
In case of combined viral and bacterial aetiology of the disease, an appropriate anti-infective therapy should be given concomitantly.
A decrease of hyperthermia is expected 12-24 hours after onset of treatment depending on the water-medicated intake.
4.5 Special precautions for use
Special precautions for use in animals
None.
Special precautions to be taken by the person administering the veterinary medicinal product to animals

4.6 Adverse reactions (frequency and seriousness)
In very rare cases an increase in blood urea levels and a decrease in blood creatinine levels may be seen.
In very rare cases somnolence, anxiety, irritability, vomiting, cutaneous rash, tachycardia, increased blood pressure, and abdominal pain may occur.
The frequency of adverse reactions is defined using the following convention:
- Very common (more than 1 in 10 animals displaying adverse reaction(s) during the course of one treatment).
- Common (more than 1 but less than 10 animals in 100 animals).
- Uncommon (more than 1 but less than 10 animals in 1,000 animals).
- Rare (more than 1 but less than 10 animals in 10,000 animals).
- Very rare (less than 1 animal in 10,000 animals, including isolated reports).
4.7 Use during pregnancy, lactation or lay
Studies in laboratory animals have not detected any teratogenic nor foetotoxic effects. However, the safety of the veterinary medicinal product has not been established during pregnancy and lactation in the target species, and this product is not indicated for use in breeding animals. Use only according to the benefit/risk assessment by the responsible veterinarian.
4.8 Interaction with other medicinal products and other forms of interaction
No interactions were investigated with commonly used antibiotics. Therefore, concomitant treatment with other products should be considered on a case-by–case basis.
Concurrent administration of nephrotoxic drugs should be avoided
4.9 Amounts to be administered and administration route
For use in drinking water.
30 mg of paracetamol per kg bodyweight per day, for 3 to 5consecutive days by oral route, i.e. 0.1 ml of product per kg bodyweight.
To ensure a correct dosage, bodyweight should be determined as accurately as possible to avoid underdosing. The uptake of medicated water depends on the clinical condition of the animals. In order to obtain the correct dosage, the concentration of paracetamol in the drinking water should be adjusted taking into account water intake.
The quantity in ml of product to be added per litre of water should be calculated as follows:
|
|
|
|
|
|
|
|
0.1 |
x |
mean b.w. of individual animals (kg) |
x |
number of animals to be treated |
|
|
Total water consumption (litres) of these animals on the previous day |

The solution should be prepared freshly every 24 hours. No other source of drinking water should be available during the medication period. The product is easily dissolved in ambient temperature water (20°C to 25°C) When using a dose proportioning pump, settings should be in the rage 3% to 5%. Do not use a setting below 3% as precipitation may occur.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
Administration of three times the recommended dose or twice the recommended treatment duration did not result in side effects.
Excessive doses could cause hepatotoxicity.
It has been reported in both human and veterinary published literature that administration of N-acetylcysteine has been used in case of overdose of paracetamol.
4.11 Withdrawal period(s)
Meat and offal: 1 day
5. PHARMACOLOGICAL PROPERTIES
Pharmaceutical group: Other analgesic and antipyretic.
ATCVet Code: QN02BE01
Pharmacodynamic properties
Paracetamol or acetaminophen is a derivative of para-aminophenol with analgesic and antipyretic properties. It inhibits the action of endogenous pyrogenic agents in pigs, by acting on the thermoregulatory centre of the hypothalamus. It is a weak inhibitor of COX-1 synthesis; therefore it has limited side effects on the gastrointestinal tract or on platelet aggregation.
Pharmacokinetic particulars
-
Absorption and distribution: after oral administration of the product via drinking water at a dose of 30 mg/kg bw, bioavailability was 81%, reaching a maximum concentration (Cmax) of 10.41 mg/l at 2 hours (Tmax) later. Presence of food slows down the rate of absorption of paracetamol. Plasma binding is low at therapeutic levels.
-
Metabolism: Paracetamol is extensively and rapidly metabolised, mainly in the liver. The main metabolites are glucuronide and sulphate conjugates.
-
Excretion: Paracetamol is rapidly excreted (t1/2: 2.23 hrs), mainly by urine as glucuronide conjugate, and in lower amounts as cysteine, unchanged paracetamol and sulphate conjugates.
