All Species
The ready-to-use oral suspension must be shaken for 20 seconds before use.
To ensure a correct dosage, body weight should be determined as accurately as
possible.
Cattle
Each animal should be treated with a single oral dose of 15 mg toltrazuril/kg body
weight corresponding to 3.0 ml oral suspension per 10 kg body weight.
For the treatment of a group of animals of the same breed and same or similar
age, the dosing should be done according to the heaviest animal of this group.
Pigs
Each pig to be treated on day 3-5 of life with a single oral dose of 20 mg
toltrazuril/kg body weight corresponding to 0.4 ml oral suspension per kg body
weight.
Due to the small volumes required to treat individual piglets, use of dosing
equipment with a dose accuracy of 0.1 ml is recommended.
Sheep
Each animal should be treated with a single oral dose of 20 mg toltrazuril/kg
body weight corresponding to 0.4 ml oral suspension per kg body weight.
If animals are to be treated collectively rather than individually, they should be
grouped according to their body weight and dosed accordingly, in order to avoid
under- or over-dosing.

Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
For further information on use in cattle please refer to the table in section 3.5 Special

It is recommended to treat all animals in a pen.
Hygienic measures may reduce the risk of coccidiosis. It is therefore,
recommended to improve concomitantly the hygienic conditions in the concerned
facility, particularly dryness and cleanliness.
To obtain maximum benefit, animals should be treated before the expected onset
of clinical signs, i.e. in the prepatent period.
To alter the course of an established clinical coccidial infection, in individual
animals already showing signs of diarrhoea, additional supportive therapy may be
required.
Treatment during an outbreak will be of limited value for the individual animal
because of damage to the small intestine having already occurred.
As with any antiparasiticide frequent and repeated use of antiprotozoals from the
same class may lead to the development of resistance.
If resistance is present it should be considered to use another antiprotozoal from
another class and with a different mechanism of action.
