No dietary control is required before or after treatment.
The veterinary medicinal product is to be administered only for the treatment of
individually fed animals or a small group of animals where the intake by individual
animals can be effectively controlled.
For the treatment and control of migrating and tissue larval stages of large
strongyles, encysted mucosal 3
rd
and 4
th
stage small strongyle larvae and encysted
inhibited 3

Recommended dosing programme
Inappropriate use of anthelmintics may increase resistance selection pressure and
lead to reduced efficacy. The decision to use this veterinary medicinal product should
be based on professional advice and take into account current best practice
recommendations for parasite control.
Treatment with this product should form part of an integrated worming plan. Consult
with your supplier for advice regarding wormers to use throughout the year.

Horses and other equines:
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 its local representative 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:
•
extended period of time.
•
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 fenbendazole has been reported in cyathostomes in horses. Therefore,
the use of this veterinary medicinal product should be based on local (regional, farm)
epidemiological information about susceptibility of nematodes and recommendations
on how to limit further selection for resistance to anthelmintics.

Special precautions for safe use in the target species:

Special precautions to be taken by the person administering the veterinary medicinal

and water.
