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 also the section 17
of the package leaflet for contact details.
Strategies that should be avoided because they might lead to an increased risk
of development of resistance to anthelmintic drugs include:
- Too frequent and repeated use of anthelmintics from the same class over an
extended period of time
- Underdosing
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.
Selection of resistant genes leading to the development of resistance can
ultimately result in ineffective anthelmintic therapy.
Additional measures regarding management and biosecurity are necessary, as
advised by the prescribing veterinarian.
