Do not use the veterinary medicinal product at this dose regimen in intensively
reared broiler chickens which are unlikely to be infected with Raillietina
echinobothrida
Unnecessary use of antiparasitics or use deviating from the instructions given in
the SPC may increase the resistance selection pressure and lead to reduced
efficacy. The decision to use the veterinary medicinal product should be based
on confirmation of the parasitic species and burden, or of the risk of infection
based on its epidemiological features, for each flock.
Repeated use for an extended period, particularly when using the same class of
substances, increases the risk of resistance development. Within a flock,
maintenance of susceptible refugia is essential to reduce that risk. Systematically
applied interval-based treatment and treatment of a whole flock should be
avoided. Instead, if feasible, only selected individual animals or subgroups should
be treated (targeted selective treatment). This should be combined with
appropriate husbandry and pasture management measures. Guidance for each
specific flock should be sought from the responsible veterinarian.
The use of this veterinary medicinal product should take into account local
information about susceptibility of the target parasites, where available.
It is recommended to further investigate cases of suspected resistance, using an
appropriate diagnostic method (e.g. Faecal Egg Count Reduction Test (FECRT).
Confirmed resistance should be reported to the marketing authorisation holder or
to the competent authorities.
