hatching (ovicidal activity) and by inhibiting the emergence of adults from eggs laid
by adult fleas (larvicidal activity).
Ticks:
The veterinary medicinal product has persistent acaricidal and repellent efficacy
against tick infestations (Rhipicephalus sanguineusIxodes ricinus for one month,
and Dermacentor reticulatus for up to three weeks).
If ticks are present when the veterinary medicinal product is applied, the ticks may
not all be killed within the first 48 hours, but they may be killed within a week. To
remove ticks, it is recommended to use an appropriate tick removal device.
Sand flies, mosquitoes and stable flies:
The treatment provides persistent repellent (anti-feeding) activity. It prevents biting
from sand flies (Phlebotomus perniciosus), mosquitoes (Culex pipiens, Aedes
aegypti) and from stable flies (Stomoxys calcitrans) for one month post-application.
The treatment also provides persistent insecticidal activity for one month against
mosquitoes (Aedes aegypti) and stable flies (Stomoxys calcitrans).

AN: 02913/2023Page 6 of 9
Step 2: With the other hand, press downwards on the smaller disk until the 2 disks
meet evenly. This will pierce the seal.

Part the hair until the skin is visible. Apply the veterinary medicinal product (as
directed in step 4 below) slowly with the tip of the applicator on the skin.
Step 4: Use according to 4a or 4b recommendation.
4a recommendation: Gently squeeze the applicator and apply the veterinary
medicinal product to the skin along the dog's back, beginning between the shoulder
blades, in the number of spots and order shown in the diagrams below and
squeezing until the applicator is empty. Avoid superficial application to the dog’s hair.
The number of application spots will depend on the body weight of the dog.
Dogs over 40 kg body weight

OR
4b recommendation: Regardless of the dog’s body weight, using
the applicator tip, part the hair at the base of the tail and begin
applying the veterinary medicinal product directly onto the skin in a
continuous line from the base of the tail along the centre of the
back all the way up to the shoulder blades, as shown in the
diagram, squeezing the applicator until it is empty.

cat, or ingested by a cat that actively grooms a recently treated dog, this veterinary
medicinal product may have serious harmful effects. (See section 3.5.)

be treated with a veterinary medicinal product authorised for use in that species.
Fleas can infest the dog’s basket, bedding and regular resting areas such as carpets
and soft furnishings. In case of massive flea infestation and at the beginning of the
control measures, these areas should be treated with a suitable insecticide and then
vacuumed regularly.
The veterinary medicinal product remains effective when treated animals are
immersed in water (e.g. swimming, bathing). Water immersion repeated weekly for
one month and starting 48 hours after treatment, as well as shampooing 2 weeks
after treatment do not affect the efficacy of this product. However, in case of frequent
shampooing, or bathing within 48 hours after treatment, the duration of activity may
be reduced.
Special precautions for safe use in the target species:
This veterinary medicinal product can induce convulsions in cats that could be fatal,
due to the unique physiology of this species which is unable to metabolise certain
AN: 02913/2023Page 3 of 9
compounds, including permethrin. In case of accidental exposure, if undesirable
effects occur, wash the cat with shampoo or soap. To prevent cats from being
accidentally exposed to the veterinary medicinal product, keep cats away from
treated dogs 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.
In case of suspicion of dermatitis (itch and skin irritation), seek veterinary advice.
The safety of the veterinary medicinal product has not been established in dogs
younger than 7 weeks or weighing less than 1.5 kg.
Care should be taken to avoid contact between the veterinary medicinal product and
the eyes of the dog. If in eyes, immediately flush with water.
The attachment of a single tick after treatment cannot be excluded. For this reason
the transmission of infectious diseases cannot be completely excluded if conditions
are favourable.

product to animals
Do not eat, drink or smoke while handling the veterinary medicinal product.
