further flea infestation for four weeks. The veterinary medicinal product can be used as

To ensure a correct dosage, body weight should be determined as accurately as

For dogs smaller 10 kg or greater 25 kg bw, use an appropriate available pipette size to
achieve the recommended dose for the weight of the animal to be treated.
For treatment or prevention of infestations with the parasites indicated for use of this
veterinary medicinal product, the need for and frequency of re-treatment(s) should be
based on professional advice and should take into account the local epidemiological
situation and the animal’s lifestyle.
In case of biting louse infestation, a further veterinary examination 30 days after
treatment is recommended as some animals may require a second treatment.
Method of administration
Remove one pipette from the package. Hold pipette in an upright position, twist and pull
off cap. Use reversed cap to twist and remove seal from pipette.
With the dog in the standing position, 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.

Do not apply an excessive amount of solution at any one spot that could cause some of
the solution to run off the side of the dog. Correct application will minimise the
opportunity for the dog to lick the veterinary medicinal product. Apply only to
undamaged skin.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.

Very rare
(<1 animal / 10,000 animals
treated, including isolated
reports):
Agitation
Hypersalivation
Disorientation, Neurological signs (e.g. Depression,
Incoordination, Tremor)
Application site reaction (e.g. Hair loss, Itching,
Reddening of the skin, Skin lesion)
May occur if the dog licks the application site immediately after treatment due to the
bitter taste. This is not a sign of intoxication and disappears within some minutes
without treatment.
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 its local representative> or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.
SPC may increase the resistance selection pressure and lead to reduced efficacy. The
decision to use the veterinary medicinal 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.
The possibility that other animals in the same household can be a source of re-infection
with fleas and biting lice should be considered, and these should be treated as
necessary with an appropriate product.
Re-infestation from emergence of new fleas in the environment may continue to occur
for six weeks or longer after treatment is initiated. More than one treatment may
therefore be required, depending on the level of fleas in the environment. To aid
reduction in environmental challenge, the additional use of a suitable environmental
treatment against adult fleas and their developing stages is recommended, especially of
the animal's basket, bedding and regular resting areas such as carpets and soft
furnishings. In order to reduce further the environmental challenge, it is recommended
that all dogs in the household are treated. Treatment of nursing bitches controls flea
infestations on both dam and offspring.
The veterinary medicinal product remains effective if the animal becomes wet, for
example after swimming or exposure to heavy rain. However, in cases of frequent
swimming or bathing re-treatment may become necessary, depending on the presence
of fleas in the environment. In these cases do not treat more frequently than once
weekly.
Special precautions for safe use in the target species:
This veterinary medicinal product is for topical use and should not be administered
orally.
Care should be taken to avoid the contents of the pipette coming into contact with the
eyes or mouth of the recipient animal.
Do not allow recently treated animals to groom each other.
