administration. The product may be safely administered to animals infected with adult
heartworms, however, it is recommended, in accordance with good veterinary

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 veterinary medicinal product may be administered year-round or at least within
one month of the animal’s first exposure to mosquitoes and monthly thereafter until
the end of the mosquito season. The final dose must be given within one 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. 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.
Treatment of biting lice
A single dose of the veterinary medicinal product should be administered.
Treatment of ear mites
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 sarcoptic mange
For complete elimination of the mites, a single dose of the veterinary medicinal
product should be administered for two consecutive months.

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:
Remove the pipette from its protective package
Holding the pipette upright, firmly depress the cap to puncture the applicator seal,
then remove the cap.
Part the hair at the base of your animal’s neck in front of the shoulder blades to
expose a small area of skin.
Apply the tip of the pipette directly to the skin without massaging. Squeeze the
pipette firmly to empty the contents in one spot. Avoid contact between the product
and your fingers.
Do not use in animals under 6 weeks of age.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
On rare occasions application of the veterinary medicinal product may produce a
local temporary clumping of the hair at the application site and/or an occasional
appearance of a small quantity of a white powder. This is normal and will disappear
typically within 24 hours of treatment administration and does not affect either the
safety or efficacy of the veterinary medicinal product.
Very rarely, as with other macrocyclic lactones, reversible neurological signs,
including seizures, have been observed after use of the veterinary medicinal product
in dogs.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse reaction(s))
- common (more than 1 but less than 10 animals in 100 animals treated)
- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- rare (more than 1 but less than 10 animals in 10,000 animals treated)
- very rare (less than 1 animal in 10,000 animals treated, including isolated reports).
Animals may be bathed 2 hours after treatment without loss of efficacy.
Do not apply when the animal’s hair coat is wet. However, shampooing or soaking
the animal 2 or more hours after treatment will not reduce the efficacy of the product.
For ear mite treatment, do not apply directly to the ear canal.
