30 mg of paracetamol per kg body weight per day, for 5 days, orally, administered in
drinking water, equivalent to 1 ml of the veterinary medicinal product per 10 kg body
weight per day for 5 days.
To ensure a correct dosage, bodyweight should be determined as accurately as
possible. The intake of medicated water depends on the clinical condition of the
animals. In order to obtain the correct dosage, the concentration of paracetamol may
need to be adjusted accordingly.
Based on the recommended dose and the number and weight of animals to be
treated, the exact daily concentration of the veterinary medicinal product should be
calculated according to the following formula:

weight / day
x
average body weight
of individual animals
(kg)
x
number of
animals to be
treated

Total water intake (litres) of animals to be treated on the previous
day
= ml of
veterinary
medicinal
product per
litre of
drinking
water
The solution should be prepared freshly every 24 hours. No other source of drinking
water should be available during the medication period.

Recommendation for dissolution:
The maximum solubility of the product in (soft/hard) water at (5ºC/20ºC) is 100 ml /L.
First add the necessary quantity of water for the preparation of the final solution in
the container. Then add the product while stirring the solution. For stock solutions
and when using a proportioner, take care not to exceed the maximum solubility which
can be achieved under the given conditions. Adjust flow rate setting of the dosing
pump according to concentration of the stock solution and water intake of the animals
to be treated.
