Flea treatment and prevention (cats and dogs)
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 (cats and dogs)
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 (cats and dogs)
A single dose of the veterinary medicinal product should be administered.
Treatment of biting lice (cats and dogs)
A single dose of the veterinary medicinal product should be administered.
Treatment of ear mites (cats)
A single dose of the veterinary medicinal product should be administered.
Treatment of ear mites (dogs)
A single dose of the veterinary medicinal product should be administered. Loose
debris should be gently removed from the external ear canal at the time of treatment.
A further veterinary examination 30 days after treatment is recommended as some
animals may require a second treatment.
Treatment of hookworm infections (cats)
A single dose of the veterinary medicinal product should be administered.
Treatment of sarcoptic mange (dogs)
For complete elimination of the mites, a single dose of the veterinary medicinal
product should be administered for two consecutive months.
Unlimited Renewal: May 2024
Method and route of administration: spot-on use.
Apply to the skin at the base of the neck in front of the shoulder blades.
How to apply:
1. Remove the pipette from its packaging. Hold the pipette in an upright position,
twist and pull the cap off.
2. Turn the cap around and place the other end of the cap back on the pipette. Push
and twist the cap to break the seal, then remove the cap from the pipette.
3. Part the coat at the base of the neck in front of the shoulder blades until the skin is
visible. Place the tip of the pipette onto the skin and squeeze the pipette several
times to empty its contents completely and directly onto the skin in one spot.
Avoid contact between the veterinary medicinal product and your fingers.
