Oral use by adding to small quantities of feed for immediate consumption by
individual pigs.
Individual Treatment – single dose
The recommended therapeutic dose is 5 mg fenbendazole per kg bodyweight as a
single dose individual treatment which is equivalent to 1g of product per 10kg
bodyweight or 5g of product per 50 kg bodyweight or 20g of product per 200 kg
bodyweight.
To ensure the correct dosage and to avoid possible under-dosing, the bodyweight
and the amount of product to be administered should be determined as accurately as
possible. To accurately measure the correct amount of product, a suitably calibrated
weighing scale should be used.
The recommended amount of veterinary medicinal product should be added to a
small quantity of the estimated daily amount of food for each individual animal in a
bucket or a similar container and mixed thoroughly prior to being offered for
immediate consumption.
Medicated feed should be freshly prepared before administration.
Part-consumed feed must be disposed of with other waste feed and not given to
other animals.

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:
•
extended period of time.
•
misadministration of the 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.
