Fleas on dogs are killed within one day following treatment. One treatment prevents
further flea infestation for four weeks. The veterinary medicinal product can be used as
part of a treatment strategy for flea allergy dermatitis (FAD).
Treatment of biting lice (Trichodectes canis).
The veterinary medicinal product has persistent acaricidal and repellent efficacy against
tick infestations (Rhipicephalus sanguineusIxodes ricinus for four weeks, and
Dermacentor reticulatus for three weeks).
Reduction of the risk of transmission of the vector-borne pathogen Ehrlichia canis,
thereby reducing the risk of canine ehrlichiosis by acaricidal and repellent activity on the
tick vector Rhipicephalus sanguineus.
from three days following application of the veterinary medicinal product and to persist for
four weeks.
Ticks already on the dog may not be killed within two days after treatment and may
remain attached and visible. Therefore the removal of ticks already on the dog at the time
of treatment is recommended, in order to prevent them from attaching and having a blood
meal.
One treatment provides repellent (anti-feeding) activity against sand flies (Phlebotomus

Underdosing could result in ineffective use and may favour resistance development.
To ensure a correct dosage, body weight should be determined as accurately as
possible.
Ticks, fleas:
The need and frequency of re-treatment(s) should be based on local epidemiological
situation and the animal’s lifestyle.
Biting lice:
In case of biting louse infestation, a further veterinary examination 30 days after
treatment is recommended as some animals may require a second treatment.
Sand flies:
To protect a dog over the whole sand fly season, treatment should be compliantly
continued throughout.
Method of administration
Remove one pipette from the package. Hold applicator pipette in an upright position, twist
and pull cap off. Turn the cap around and place the other end of cap back on pipette.
Twist cap to break seal, then remove cap from pipette.
With the dog standing still, part the coat between the shoulder blades until the skin is
visible. Place the tip of the pipette on the skin and squeeze firmly several times to empty
the contents directly onto the skin.

Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or the national competent authority via the
national reporting system. See the package leaflet for respective contact details.

canis from three days following application of the veterinary medicinal product and to
persist for four weeks.
Immediate protection against sandflies bites is not documented. Treated dogs for the
reduction of the risk of infection with Leishmania infantum via transmission by sandflies
Phlebotomus perniciosus should be kept in a protected environment during the first 24
hours after the initial treatment application.
To reduce re-infestation from emergence of new fleas, it is recommended to treat all
dogs in a household. Other animals living in the same household should also be treated
with a suitable product. To aid further in reducing environmental challenge, the additional
use of a suitable environmental treatment against adult fleas and their developmental
stages is recommended.
The veterinary medicinal product remains effective if the animal becomes wet. However,
prolonged, intense exposure to water should be avoided. In cases of frequent water
exposure the persistent efficacy may be reduced. In these cases do not retreat more
frequently than once weekly. If a dog requires a shampoo, it should be administered
before applying the veterinary medicinal product or at least 2 weeks after application, to
optimise efficacy of the veterinary medicinal product.
The possibility that other animals in the same household can be a source of re-infection
with fleas, biting lice, ticks, mosquitoes and flies should be considered, and these should
be treated as necessary with an appropriate product.
In the absence of risk of co-infection, a narrow spectrum veterinary product should be
used. The use of this veterinary medicinal product should take into account local
information about susceptibility of the target parasites, where available.
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 animal.
In Europe, resistance to pyrethroids has been reported in isolated cases of Rhipicephalus
sanguineus and. Current knowledge suggests that resistance in both
parasites is conferred by gene mutations at the target site while other factors like
metabolic detoxification may also play a role.
Special precautions for safe use in the target species:
Care should be taken to avoid the content of the pipette coming into contact with the
eyes or mouth of the recipient dogs.
Care should be taken to administer the veterinary medicinal product correctly as
described under section 3.9. In particular oral uptake due to the licking of the application
site by treated or in-contact animals should be avoided.
Do not use on cats.
This veterinary medicinal product is extremely poisonous to cats and could be fatal due
to the unique physiology of cats which is unable to metabolise certain compounds
including permethrin. To prevent cats from being accidentally exposed to the veterinary
medicinal product, keep treated dogs away from cats after treatment until the application
site is dry. It is important to ensure that cats do not groom the site of application on a
dog, which has been treated with this veterinary medicinal product. Seek veterinary
advice immediately if this occurs.
Consult your veterinary surgeon before using the veterinary medicinal product on sick
and debilitated dogs.
Ticks will be killed and fall off the host within 24 to 48 hours after infestation without
having 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.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
Avoid contact between the veterinary medicinal product and skin, eyes or mouth.
Do not eat, drink or smoke during application.
Wash hands thoroughly after use.
In case of accidental spillage onto skin, wash off immediately with soap and water.
People with known skin sensitivity may be particularly sensitive to this product.
People with known hypersensitivity to imidacloprid and permethrin should administer the
veterinary medicinal product with caution.
The predominant clinical symptoms that in extremely rare case may be shown are
transient sensory irritations of the skin like tingling, burning sensation or numbness.
If the veterinary medicinal product gets accidentally into the eyes, the eyes should be
thoroughly flushed with water.
If skin or if eye irritation persists seek medical advice immediately and show the package
leaflet or the label to the physician.
Do not ingest. In case of accidental ingestion seek medical advice immediately and show
the package leaflet or the label to the physician.
Treated dogs should not be handled especially by children until the application site is dry.
This may be ensured by treating the dogs e.g. in the evening. Recently treated dogs
should not be allowed to sleep together with their owner, especially children.
In order to prevent children from getting access to pipettes, keep the pipette in the
original packaging until ready for use and dispose of used pipettes immediately.
Special precautions for the protection of the environment:
As the veterinary medicinal product is dangerous to aquatic organisms, treated dogs
must not under any circumstances be allowed into any type of surface water for at least
48 hours after treatment.
Other precautions:
The solvent in this veterinary medicinal product may stain certain materials including
leather, fabrics, plastics and finished surfaces. Allow the application site to dry before
permitting contact with such materials.
After opening the foil pouch store in a dry place at a temperature not above 30°C.
