before disease has developed, fasciolosis can be prevented.
Unscrew the cap from the container and replace it with the white spigot cap provided.
If using an automatic drenching-gun, attach the tube from the application device to
the white spigot cap. After use, remove the white spigot cap and close the container
with the cap.
All pack sizes:
To ensure a correct dosage, body weight should be determined as accurately as
possible: accuracy of the dosing device should be checked. If animals are to be
treated collectively rather than individually they should be grouped according to their
bodyweight and dosed accordingly, in order to avoid under- or over-dosing.
Administer 5 mL/100 kg body weight, equivalent to 12 mg triclabendazole per kg of
body weight. The veterinary medicinal product is administered orally after thorough
shaking of the suspension. Most types of automatic drenching guns are suitable.
Clean drenching gun before and after use.
The veterinary medicinal product can safely be given to young, pregnant or stressed
cattle, cattle not producing milk intended for human consumption or dry cattle.
The veterinary medicinal product is given once. The administration may be repeated
several weeks or months after the first treatment depending on the epidemiological
situation.
In case of acute fasciolosis, treat immediately, then repeat in approximately 4-6
weeks, and consult a veterinarian for advice.

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.
Care should be taken to avoid the following practices because they increase the risk
of development of resistance and could ultimately result in ineffective therapy.
• Too frequent and repeated use of anthelmintics from the same class, over an
extended period
of time.
• Underdosing, which may be due to underestimation of bodyweight,
misadministration of the
veterinary medicinal product, or lack of calibration of the dosing device (if any).
Suspected clinical cases of resistance to anthelmintics should be further investigated
using appropriate tests (e.g. Faecal Egg Count Reduction Test).
Where the results of the test(s) strongly suggest resistance to a particular
anthelmintic, an anthelmintic belonging to another pharmacological class and having
a different mode of action should be used.
Resistance to triclabendazole has been reported in Fasciola hepatica in a number of
countries including ones in the EU. Therefore, the use of this veterinary medicinal
product should be based on local epidemiological information about susceptibility of
F. hepatica
anthelmintics. Dosing programmes should be discussed with your Veterinary Adviser.
