Flea treatment and prevention
Following administration of the veterinary medicinal product, the adult fleas on the
animal are killed, no viable eggs are produced, and larvae (found only in the
environment) are also killed. This stops flea reproduction, breaks the flea lifecycle
and may aid in the control of existing environmental flea infestations in areas to
which the animal has access.
For the prevention of flea infestations, the veterinary medicinal product should be
administered at monthly intervals throughout the flea season, starting one month
before fleas become active. Through a reduction in the flea population, monthly
treatment of pregnant and lactating animals will aid prevention of flea infestations in
the litter up to seven weeks of age.
For use as part of a treatment strategy for flea allergy dermatitis the veterinary
medicinal product should be administered at monthly intervals.
Prevention of heartworm disease
The need for treatment should be determined by the prescribing veterinarian and
should be based on the local epidemiological situation (see section 3.4). For
prevention of heartworm disease, the veterinary medicinal product should be
administered within one month of the animal’s first exposure to mosquitoes and
monthly thereafter until 1 month after the last exposure to mosquitoes. If a dose is
missed and a monthly interval between dosing is exceeded then immediate
administration of the veterinary medicinal product and resumption of monthly dosing
will minimise the opportunity for the development of adult heartworms. The need for
extended treatment should be determined by the prescribing veterinarian. When
replacing another heartworm preventive veterinary medicinal product in a heartworm
disease prevention programme, the first dose of the veterinary medicinal product
must be given within a month of the last dose of the former medication.
Treatment of roundworm infections
A single dose of the veterinary medicinal product should be administered.

animals may require a second treatment.
Treatment of sarcoptic mange

product should be administered for two consecutive months.
