Prevexto 1.25 g + 0.56 g, Medicated Collar for Cats

Ticks already on the cat prior to treatment may not be killed within 48 hours after collar
application and may remain attached and visible. Therefore removal of ticks already
on the cat at the time of application is recommended. If you are unsure how to safely
remove ticks from your animal, seek professional guidance. The prevention of
infestations with new ticks starts within two days after application of the collar.
Ticks will be killed and fall off the host within 24 to 48 hours after infestation without
having had a blood meal, as a rule. An attachment of single ticks after treatment cannot
be excluded. For this reason, a transmission of infectious diseases by ticks cannot be
completely excluded if conditions are unfavourable.
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 product should be based on confirmation of the parasitic species
and burden, or of the risk of infestation based on its epidemiological features, for each
individual.
The use of this product should take into account local information about susceptibility
of the target parasites, where available.
In the absence of risk of co-infestation by fleas and ticks, a narrow spectrum product
should be used.
Ideally, the collar should be applied before the beginning of the flea or tick season.
As in all long-term topical products, periods of excessive seasonal hair shedding may
lead to transient slight reduction of efficacy by loss of hair-bound portions of the active
ingredients. Replenishment from the collar starts immediately so that full efficacy will
be re-established without any additional treatment or collar replacement.
For optimum control of flea problems in heavily infested households it may be
necessary to treat the environment with a suitable insecticide.
Fleas can infest pets’ beds, sleeping areas and usual resting areas like rugs and sofas.
In the event of a massive infestation, these places should be treated with a suitable
insecticide and vacuumed regularly.
The possibility that other animals in the same household can be a source of re-
infestation with fleas or ticks should be considered, and these should be treated as
necessary with an appropriate product.
The veterinary medicinal product is water resistant; it remains effective if the animal
becomes wet. However, shampooing or prolonged, intense exposure to water should
be avoided as the duration of activity may be reduced.
