Clinical information

Chanox Multi 50 mg/ml Oral Suspension for Piglets, Calves and Lambs — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

Calves: For the prevention of clinical signs of coccidiosis and reduction of coccidia
shedding in housed calves replacing cows producing milk for human consumption
AN: 00545/2025 & 00547/2025
(dairy cows) on farms with a confirmed history of coccidiosis caused by
or Eimeria zuernii.
Lambs: For the prevention of clinical signs of coccidiosis and reduction of coccidia
shedding in lambs on farms with a confirmed history of coccidiosis caused by
crandallis and Eimeria ovinoidalis.

The oral suspension must be shaken before use.
To ensure a correct dose, body weight should be determined as accurately as
possible.
To obtain maximum benefit, animals should be treated before the expected onset of
clinical signs, i.e. in the prepatent period.
Piglets
Individual animal treatment.
Each piglet should be treated between days 3 - 5 of life with a single oral dose of 20
mg toltrazuril per 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.
Treatment during an outbreak will be of limited value for the individual piglet because
of damage to the small intestine having already occurred.
Calves
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.
If animals are to be treated collectively rather than individually, reasonably
homogeneous groups of the same breed and same or similar age should be set up,
and all animals of a group should be dosed at the rate corresponding to the heaviest
one.
Lambs
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, reasonably homogeneous groups
should be set up, and all animals of a group should be dosed at the rate
corresponding to the heaviest one.

Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
For environmental reasons:
Do not use in calves weighing more than 80 kg bodyweight.
Do not use in fattening units such as veal or beef calves.
For more details see sections 3.5, other precautions and section 4.3, environmental
properties.

None Known.
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or the national competent authority via the
national reporting system. See the package leaflet for respective contact details.

As with any antiparasiticide frequent and repeated use of antiprotozoals from the same
class may lead to the development of resistance.
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
with regard to 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 to the individual piglet because
of damage to the small intestine having already occurred.

Special precautions for safe use in the target species:
Not applicable.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
People with known hypersensitivity to toltrazuril, or any of the excipients, should
AN: 00545/2025 & 00547/2025
avoid contact with the veterinary medicinal product.
This product can cause skin and eye irritation.
Avoid skin and eye contact with the product.
In case of accidental exposure to the skin or eyes, wash the affected area thoroughly
with plenty of water.
If irritation persists, seek medical advice and show the package leaflet or the label to
the physician.
Do not eat, drink or smoke whilst using the product.
Special precautions for the protection of the environment:
The major metabolite of toltrazuril, toltrazuril sulfone (ponazuril), has been shown to
be both persistent (half-life >1 year) and mobile in soil and to be toxic to plants.
Calves: In order to prevent any adverse effects on plants and possible contamination
of groundwater manure from treated calves must not be spread onto land without
dilution with manure from untreated cows. Manure from treated calves must be
diluted with at least 3 times the weight of manure from mature cows before it can be
spread onto land.
Lambs kept throughout the whole life span indoors under an intensive rearing system
must not be treated beyond the age of 6 weeks or body weight of more than 20 kg at
treatment. Manure from these animals should only be applied to the same piece of
land every third year.
